Campus Public Safety: Emergency or Non-emergency, extension 8888

City of Cambridge: ambulance, police, fire, 9-911

If you discover a fire, smoke, toxic vapors, or a chemical/oil spill:

R - Remove: Remove people in immediate danger without endangering

yourself, then:

A - Activate: Fire: Activate nearest fire alarm box (near exit), exit, & call 8888.

Chemical Spill/Leak: Leave and notify Physical Plant, 8881.

Provide the location

C - Confine: IF YOUR SAFETY WILL NOT BE ENDANGERED:

Fire: Close fire doors, windows and switch off exhaust fans

Spills/leaks: Leave windows open & exhaust fans on Turn off airsupply (recirculates)

Plan your escape: Never permit fire to get between you and anescape route

E - Evacuate: Evacuate the building (in case of fire) or the area (in case of a

spill/leak) Leave via a safe fire exit NEVER use elevators in aFire Only use the stairs

R.A.C.E.: If smoke, flames, toxic vapors, or any other emergency is discovered: Leave the area, call

Public Safety, 8888, and provide information about the incident

• Alarm Locations: Fire alarm pull stations devices are located throughout each building, near exits.

Alarm signals are located on each floor & are audible bell/siren and/or visual (strobe) & audible alarms

Do not attempt to extinguish a fire, unless you have been trained to use an

extinguisher

• Emergency Exits: Use the primary or the closest emergency egress route unless it is unsafe Exits are

equipped with illuminated exits signs Follow these exit signs to the nearest ground level exit.

• Assembly Areas: Use the closest egress route, if it is safe, and go to the designated assembly area or

the closest, clear area that is at least 150 feet from the building Do not obstruct emergency personnel or vehicle access Account for all evacuated students, visitors, faculty, and staff Notify the person-in- charge of unaccounted individuals or observations requiring further action.

• Special Needs: Identify those persons who may need to be alerted or assisted Provide assistance as

required.

• Check: Quickly inspect each room in your area as you exit to ensure that everyone has been

evacuated However,

Do not endanger yourself!

• Chemical Emergencies: It is unlikely that a chemical emergency will require a building evacuation.

However, if you discover chemical emergency, leave the area, secure the room, and notify Public Safety (8888) Lesley University provides trained and authorized response personnel who will evaluate the situations and take appropriate action to control the incident Evacuate all affected areas as necessary.

If trained and authorized to use them, chemical spill kits are available through the Chemistry and

Cambridge, Massachusetts

Emergency Response Guidelines

Chemical Spill / Accident / Explosion

• Notify Security at 617.349.8888 Provide location and chemical information, if known, and have someone stay on line to give additional information while

emergency units are in route

• Obtain Safety Data Sheet (SDS) from the Safety Coordinator for the spilled

chemical, if known All SDS Sheets are kept in room 2-143 in the filing cabinet drawer marked “”

• Any chemical cloud that can affect community members in their offices would very likely affect them outside in the assembly area If time is of prime importance, it may be necessary to evacuate several blocks from the building by foot If this occurs, move crosswind or upwind to avoid fumes or vapors, never downwind When appropriate, proceed to assembly areas listed below

• NOTE: Do not attempt to clean up a hazardous chemical spill Physical Plant Personnel will arrange for clean up through an environmental service

provider.

Fire Emergency

• Never endanger your personal safety or the safety of others If the fire can't be readily extinguished activate the closest fire alarm pull station if available

• Evacuate the building

• After Evacuation, call 911 and security (617) 349-8888 Report street address, etc

• Report to your designated assembly area: parking lot next to 49 Roseland St

Important fire emergency issues:

• Never silence the fire alarm panel

• Do not use elevators during a fire alarm

• Use caution when entering a fire scene (feel doors for heat prior to opening)

• Always evacuate the building

Regulatory Notifications

Contact the Physical Plant (x 8881) to determine if regulatory notifications are required

See the Emergency Contact list.

When notified to evacuate, proceed as follows:

• Alert nearby personnel of the emergency

• Quickly shutdown operating equipment (e.g gas or vacuum lines)

• Calmly and expeditiously proceed to the nearest exit

• Close fire doors when exiting

• Leave room (e.g., office, bathroom, etc.) doors open (To permit an occupant survey.)

• Designated personnel should check offices, bathrooms, and other spaces while proceeding to the exit

• Use the nearest exit or stairs to exit the location

• Walk, do not run

• Inform all persons seen en-route to the exit of the evacuation notification

• Upon exiting the building, proceed to the parking lot adjacent to 49

Roseland Street or move at least 150 feet from the affected location

• Upon arrival at the assembly area, report to the person in chargeimmediately and provide critical information such as, event causes, injuredemployees, observations noted during exit, unaccounted people, etc

• Await further instructions from the person in charge

• Never leave the assembly area without authorization from the person in charge

Never re-enter a building or affected area until permitted by the Shift

Supervisor (Emergency Coordinator / Incident Commander).

3.0 Hazard Identification and Communication

3.1 Introduction

A hazardous chemical is defined by OSHA's laboratory standard as "a chemical forwhich there is statistically significant evidence based on at least one study conducted inaccordance with established scientific principles that acute or chronic health effects mayoccur in exposed employees." Hazardous chemicals include carcinogens, toxic or highlytoxic agents, reproductive toxins, irritants, corrosives, sensitizes, hepatotoxins,nephrotoxins, neurotoxins, agents which act on the hematopoietic system and agentswhich damage the lungs, skin, eyes or mucous membranes.”

3.2 Hazard Communication

By communicating information about chemical hazards, safe work practices can beidentified thereby facilitating the management of risks Lesley University will use thefollowing methods to communicate information on the chemical hazards

3.2.1 Signs:

• Emergency Information: Post a copy of the (completed) Emergency Information Data

and “Emergency Numbers”, notices, found at the beginning of the CHP at theentrance to each laboratory and by phones, where available

• National Fire Protection Association (NFPA) 704 “Diamond”: Display at the entrance

to each laboratory an NFPA 704 diamond Prepare the diamond following guidancedescribed in the NFPA 704 standard

• Massachusetts Water Resources Authority (MWRA): Post notices required by theMWRA See Physical Plant

3.2.2 Labels:

• Manufacturers’ Labels: Do not remove, deface, or obscure labels on incomingcontainers of hazardous chemicals The manufacturers’ labels identify thechemical(s) or product and contain chemical hazard information This informationcan be used to rapidly identify the chemical’s hazards and locate the correspondingSDS

• “ Secondary” Containers: Label secondary containers with the chemical name(s) andhazard identification(s) Secondary containers are those that are filled from originalshipping or manufacturer's containers

“ Secondary” Container Labeling Notes: Containers intended only for the immediate use (within one work shift) of the Laboratory Instructor or Supervisor transferring the chemical from a labeled container do not require labeling; however, labeling of these containers is strongly recommended Containers of chemicals that are used by more than one Instructor or Supervisor or for longer than one work shift must be labeled with the following information:

• Chemical Name,

• Concentration, and

• Appropriate hazard warnings, e.g., inhalation hazard, causes dermatitis, etc.

Unlabeled Secondary Container: Secondary containers with unknown contents should be segregated and not handled Contact the CHO with a description and the container’s location The CHO will arrange for analysis and proper disposal.

Disposal of Materials in Unknown Containers: Containers with “unknown” contents must be handled

as “unknown” until their contents can be verified These containers must be placed in the nearest hazardous waste Satellite Accumulation Area, SAA The container contents will be verified and the

proper disposal method identified Please note: Verifying the contents and hazards of an unknown

container is an extremely time-consuming and costly process To control costs and minimize laboratory disruption, properly label all containers to avoid generating “unknowns” Attempt to identify the contents of any unlabeled container or containers with unknown contents by locating the person who transferred the material into the secondary container Contact the CHO for guidance.

• Peroxide Forming Chemicals: Label peroxide forming chemicals with the receivedate and the date the container is opened After the recommended disposal date,test the chemical for peroxides or dispose of properly (See Table 1 for a list ofperoxide forming chemicals, peroxide testing protocols, and mandatory disposaldates.)

• Shipping Hazardous Chemicals Off Campus: Shipping hazardous chemicals offcampus requires special training and procedures Contact the CHO for guidance andassistance

3.2.3 Additional Labeling Guidelines:

• Over-the-Counter Materials: Over-the-counter materials available to the public areexempt from labeling requirements if the manufacturer has already labeled theproduct and the material remains in the original container If the material istransferred to a secondary container, it must be labeled as described above

• Stationary Process Vessels: Stationary process containers such as tanks may beidentified with signs, placards, process sheets, batch tickets or other writtenmaterials, in lieu of affixing labels to process containers A sign or placard mustconvey the same information that a label would and must be visible to employeesthroughout the work shift

• Sample Containers: Label sample containers or prepared solutions If there is alarge quantity of containers with the same chemical, label the container, tray, shelf,cupboard, refrigerator, etc

3.2.4 Safety Data Sheets (SDSs): SDSs are documents prepared by the manufacturer

or importer for each hazardous chemical or products and summarizes the properties,hazards, and precautions for safe handling and use SDSs are readily accessible to alllaboratory personnel Each lab will maintain in the lab, SDSs received with incomingshipments of hazardous chemicals Laboratory Personnel will have access to the printversion of SDSs Please note: SDSs for over-the-counter materials must be maintained

if the material is used in a manner other than its intended purpose

3.3 Chemicals Developed In the Laboratory: Contact the CHO if development ofhazardous materials or chemicals is anticipated in the Lab Additional action is required.3.4 Prior Review / Approval

Prior to using the materials or performing operations listed below, the LaboratoryInstructor, CHO, Student, or others must obtain prior approval from the LaboratorySafety Committee To obtain “prior approval” the Laboratory Instructor must completethe form in Appendix D, Safety Guide They should submit the form to the LaboratorySafety Committee for review and approval, prior to using the material or performing theoperation Contact Physical Plant for assistance identifying technical safety, industrialhygiene or environmental compliance resources

3.5 “Particularly Hazardous Substances”

Due to the hazards posed by handling OSHA designated, “Particularly HazardousSubstances”, special precautions are required when working with the following:

1 Select carcinogens: Any substance which meets one of the following criteria:

• regulated by OSHA as a carcinogen (Appendix E, Table 6);

• listed under the category, "known to be carcinogens," in the Annual Report onCarcinogens published by the National Toxicology Program (NTP) (latest edition);

• listed under Group 1 ("carcinogenic to humans") by the International Agency forResearch on Cancer (IARC) Monographs (latest edition); or

• listed in either Group 2A or 2B by the IARC, or under the category, "reasonablyanticipated to be carcinogens" by NTP, or any other substance that causesstatistically significant tumor incidence in experimental animals in accordancewith criteria specified in the OSHA laboratory standard

2 Reproductive toxins: Chemicals which affect the reproductive capabilities, includingchemicals which produce chromosomal damage (mutagenic or mutagens) and thoseeffecting the fetus (teratogenic or teratogens);

3 Substances with a high degree of acute toxicity: Chemicals of High Acute Toxicityinclude, but are limited to, such chemicals as diisopropylfluorophosphate,hydrofluoric acid, hydrogen cyanide, etc

When an Instructor is planning use of a particularly hazardous substance, they musttake the following steps prior to using the substance:

• Develop a Safety Guide (Appendix D)

• Obtain prior approval from the Laboratory Safety Committee

• Take the action specified in Sections 3.5.1 to 3.5.5

Appendix D, the Safety Guide, provides a simple format for outlining and documentingthe information necessary to identify hazards and document precaution for the safe use

of particularly hazardous substances Prior to handling particularly hazardoussubstances, Laboratory Faculty must review, implement, and inform all appropriateLaboratory Personnel of the Safety Guide information as outlined in Section 3.4.1,Safety Guide Communication

3.5.1 Establish a Designated Area

Particularly hazardous substances, as defined above, must be used and stored only indesignated areas Designated areas may be: a restricted access fume hood, (ductlesshoods can not be used), glove box, or other lab location designated for use of theparticularly hazardous substance The Laboratory Instructor will identify, specify, andcommunicate, the designated location to laboratory personnel S/he will communicateall appropriate safety precautions for the particularly hazardous substances through use

of signage, labels, personal communications, and other acceptable means Additionally,containers, storage areas, etc holding particularly hazardous substances will be labeled

or provided with appropriate signage as specified in Section 3.4, Labeling/Signage.When not in use, these materials will be secured under lock and key Access will belimited to the Laboratory Instructor or CHO

3.5.2 Designate “Containment Devices”

Particularly hazardous substances must be used in a fume hood, glove box or othercontainment device to prevent or control generation or release of aerosols or vapors to

the laboratory or community Ductless fume hoods shall not be used for particularly

hazardous substances Containers holding particularly hazardous substances will bestored in chemical-resistant trays Apparatus or procedures involving particularlyhazardous substances will be performed on or mounted above chemical-resistant trays,

or the work area will be covered with removable, absorbent, containment devices orequally effective measures needed to contain spillage, leakage, release, or damage

3.5.3 Identify Contaminated Waste Removal Methods

Prior to introducing a particularly hazardous substance into a laboratory, the Instructorwill contact CHO to determine the appropriate hazardous waste handling and disposalrequirements If the substance will require changes to LU’s waste generator status, theInstructor must obtain “Prior Approval” as outlined in Section 3.4, prior to purchasing thesubstance Generator status could change, for example if more than one pound of “P”listed waste is generated, or large quantities of waste will be generated The LaboratoryInstructor and CHO must follow EPA/MassDEP hazardous waste managementrequirements for disposal of hazardous waste generated by the use of the particularlyhazardous substance

3.5.4 Develop Decontamination Guidelines

The Laboratory Instructor must develop guidelines for decontaminating spills orreleases of particularly hazardous substances Decontamination techniques explained

in the guidelines can only be used by trained, designated, and authorized emergencyresponders These may be contract or other responders (e.g., fire/police department,hazmat, etc.)

3.5.5 Obtain Prior Approval

Prior to introducing a particularly hazardous substance into the laboratory, theLaboratory Instructor must request and receive “prior approval” by the Laboratory SafetyCommittee See Section 3.4

4.0 Safety Guidelines (“Standard Safety Practices”)

4.1 Introduction

Lesley University has developed safety guidelines for various laboratory operations.These guidelines are designed to provide general safety guidance for Laboratorypersonnel working in LU laboratories Where the scope or nature of laboratory operation

is not specifically addressed by these safety practices, the Laboratory Instructor and/orCHO can use the Safety Guide format, Appendix D, to develop specific procedures toidentify appropriate precautions to manage operational risks Appendix D provides atemplate to identify appropriate safety information Please contact the Director ofFacilities and Operations for guidance or assistance developing the Safety Guide TheLaboratory Safety Committee must approve the completed guideline

Note: The information presented below is adapted from various College and University

safety websites and technical laboratory safety references References include: Safety

in Academic Chemistry Laboratories (American Chemical Society); Prudent Practices for Handling and Disposing of Hazardous Chemicals (National Research Council,

1995) See Appendix J, Electronic Resources, for additional information and references.4.2 General Safety Practices

The following general safety practices have been developed to alert personnel to

inherent laboratory hazards and to provide generalized methods to prevent and control exposure to hazards and maintain a basic level of laboratory safety

3 Post emergency numbers by lab phones Update the phone list when changes occur.

4 Identify the location of emergency equipment - fire alarms, fire extinguishers, eyewash and safety showers

5 Check emergency equipment regularly to ensure its readiness This includes fire extinguishers, hood alarms, eyewash / emergency showers, spill kits, and spill containment equipment, gas line shutoffs

6 Ensure that first aid supplies are stocked and available Contact Physical Plant for assistance acquiring and stocking kits.

7 Before lab work begins, formulate an emergency contingency “plan” for the particular procedure or experiment Plan for fire, spill, personnel exposure, etc When working with chemicals that are particularly hazardous or odiferous, inform the Laboratory Safety Committee, CHO, or Physical Plant

8 Should a fire alarm sound, immediately evacuate the building If it will not delay evacuation, close hood sashes before leaving.

9 Maintain constant communication with others in the lab If you will be working alone, see Section 4.2.12

10 Do not block exits, emergency equipment (fire extinguishers) or hazard controls, e.g., safety shower / eye washes Do not use hallways and stairways for storage.

4.2.2 Controlling Chemical Exposure

Laboratory personnel must use work practices and techniques that minimize personal and coworker exposure to laboratory chemicals The authorization to handle hazardous chemicals is an individual's commitment to handle and use the chemicals properly, from receipt to disposal Information on the proper handling, storage and disposal of

hazardous chemicals and access to related SDSs is available to all laboratory users prior to handling chemicals Only trained and LU authorized employees may work in the LU’s laboratories, handle chemicals, etc

1 Consult Safety Data Sheets (SDSs) for chemical substances that will be handled (See Appendix C ).

2 Consider substituting less toxic chemicals for those with a higher degree of toxicity, e.g., lower, Occupational Exposure Limits, OSHA permissible exposure limit (PEL), or ACGIH threshold limit value (TLV), etc.

3 Assume that a chemical mixture is at least as toxic as its most toxic component

4 Label chemicals and equipment with appropriate hazard notations (See Section 3.2.2 )

5 Assume substances of unknown toxicity are extremely toxic.

6 Review SDSs for chemicals you handle Review symptoms of exposure and precautions necessary to minimize exposure

7 Replace container labels that are missing, defaced, or that do not meet appropriate packaging regulations

8 Do not store chemicals on high shelves Large or bulky containers should be stored no more than two feet above floor level

9 Segregated / store chemicals by compatibility, not alphabetically.

10 Label chemical storage areas with their contents (see Labeling, Section 3.2.2 )

11 Maintain minimum quantities of chemicals at the lab bench or in work areas Store excess, unused,

or inventoried chemicals in a Storeroom.

12 Wear designated and appropriate personal protective equipment (PPE) (See Section 5.7 , PPE).

13 Inspect protective and exposure control equipment for damage before use DO NOT USE defective equipment

14 Avoid skin contact with chemicals In the event of skin contact, wash thoroughly with copious amounts

of water and seek assistance, when necessary and appropriate.

15 Even when gloves are worn, wash hands thoroughly with soap and water after working with hazardous chemicals Wash thoroughly before contacting consumables or leaving the laboratory.

16 Be sensible in grooming and attire Observe the following practices: Tie back long hair Do not wear artificial fingernails, which may be a fire hazard Wear fitted clothing, preferably long and of natural fabric Wear flat, closed shoes Do not wear plastic jewelry.

17 Add reagents together, slowly Add concentrated solutions to diluted ones with stirring.

18 Keep your work area clean and uncluttered and be sure it is reasonably clean and clear at the end of each work day, operation, or experiment.

19 Carefully consider when it is appropriate to work in a laboratory fume hood For example, work in the hood with lachrymators, foul-smelling compounds, suspected carcinogens, or teratogens (reproductive toxins), etc For additional guidance on use of laboratory fume hoods, see Section 5.2

20 Do not use the mouth for vacuum or suction for pipeting or starting a siphon.

21 Never taste or smell any chemical substance.

22 Do not eat or drink, handle, or store food or beverages in the laboratory area or in laboratory refrigerators Do not use laboratory glassware or utensils for food or beverages Do not apply cosmetics in a lab area.

23 Use a bottle carrier for secondary containment when transporting chemicals from a stockroom or into common areas such as hallways or elevators

24 Do not smoke in the building.

25 Consult the Laboratory Instructor or CHO for additional and specific precautions that should be implemented, based on the toxicological characteristics of individual chemicals substances.

26 Notify the Laboratory Instructor or CHO in the event of an exposure incident, spill, or other event.

4.2.3 Guidelines for Fume Hood Use

The protection afforded by a fume hood is only as good as the work practices used Thefollowing are general guidelines when working in a fume hood:

1 Do not break the plane of the hood face with the head.

2 The hood sash or panels should be closed to the maximum position possible while still allowing comfortable working conditions.

3 Keep the sash completely lowered anytime no "hands-on" part of an experiment is in progress or whenever the hood is on and unattended.

4 Minimize or eliminate storage inside the hood If equipment must be stored in the hood, ensure it does not block airflow to slots in the baffle.

5 Tape a line approximately 6 inches behind the sash Maintain all chemicals and equipment behind that line This will help keep vapors from escaping the hood when air currents from people passing the hood, etc interfere with airflow at the hood face.

6 Never work in a hood unless there is clear (visual) indication that the hood is operating A tissue or Kimwipe taped to the sash or inside the hood can be used to confirm airflow.

7 Visually inspect the baffles (openings at the top and rear of the hood) to ensure slots are open and unobstructed.

8 Do not block baffles If large equipment is stored in the hood, put it on blocks to raise it approximately two inches so that air may pass beneath it.

9 Do not use the hood for storage Keep only the materials necessary for the experiment inside the hood If chemicals need to be stored in the hood for a period of time, install shelves on the sides of the hood, away from the baffles.

10 Keep the sash clean and clear.

11 The hood is not a substitute for personal protective equipment (PPE) Wear appropriate, required PPE, e.g., gloves, safety glasses, etc., as appropriate.

12 Flammable liquids should not be stored permanently in the cabinet under the hood unless that cabinet meets the requirements of ANSI/NFPA 30 and 45 for this type of storage.

13 The hood sash or panels should not be removed except as necessary for set-up and should be replaced as soon as practicable.

14 Each hood must be posted with a notice giving the date of the last periodic evaluation

15 Do not use hoods during maintenance outages.

16 Clean all chemical residues from the hood chamber after each use

17 Connect electrical devices outside the hood to avoid sparks which may ignite a flammable or explosive chemical.

18 Only use a hood for the function it was designed Certain chemicals or reactions require specially constructed hoods, e.g., perchloric acid, high pressure reactions, others Most special use hoods are labeled as to the uses for which they are designed If you have any questions about the capabilities of

a particular hood, contact the Laboratory Instructor of CHO.

4.2.4 Laboratory Equipment

1 Inspect laboratory equipment on a periodic basis and replace or repair as necessary Don't neglect to check electrical cords for frayed wiring, effective ground connections, etc.

2 Use laboratory equipment only for its intended purpose or an appropriate modification.

3 Handle and store glassware in such a manner as to minimize breakage.

4 Shield evacuated glass apparatus to contain chemicals and glass fragments should implosion occur.

4.2.5 Waste Storage

This information and the sections on Waste Treatment and Waste Disposal containspecific EPA requirements Contact Physical Plant for additional information orguidance

1 Consult Physical Plant for LU’s hazardous waste storage policy.

2 Follow prudent practice to segregate waste according to hazard class, disposal requirements, etc Have separate containers for halogenated and non-halogenated materials and for corrosives.

3 Remove or completely obscure a container’s label prior to using it for hazardous waste accumulation.

4 Label each waste container with the specific wording "Hazardous Waste" unless the contents are not hazardous waste, and indicate the hazard class (for example, corrosive, toxic, reactive, etc.) if known Contact Physical Plant for guidance on other information to include on the hazardous waste container.

5 Keep screw caps on waste containers tightly closed except when material is being added or removed.

6 Provide secondary containment which holds the volume of the largest container or at least 10% of the volume of all containers in the satellite accumulation area.

7 Do not transfer waste from the room in which it was generated

8 Contact Physical Plant when hazardous waste containers are full to arrange for the removal.

9 Use approved containers provided for "sharps": syringe needles, disposable syringes, and razor blades.

1 Never pour chemical waste in a sink or down the drain.

2 Remove from the lab, hazardous waste containers within three days of a container becoming full Contact Physical Plant for a waste container pickup Waste cannot be transferred to a larger container for the purpose of extending the storage period.

3 Only containers that are acceptable for disposal will be removed by the hazardous waste vendor Acceptable containers must be tightly closed and in good condition Contact Physical Plant for guidance.

4.2.8 Eating, Drinking, Smoking, etc.

Due to obvious issues, no eating, drinking, smoking, or applying cosmetics is permitted in laboratories.

LU does not permit the storage (including in laboratory refrigerators, storage cabinets, etc.), use, or disposal of 'consumable' items in laboratories

4.2.9 Container Handling

Take the listed action when transporting chemicals:

1 Carry glass containers in specially designed bottle carriers or leak resistant, unbreakable secondary containers.

2 When transporting chemicals on a cart, use a cart that is suitable for the load and one that has high edges to contain leaks or spills.

3 When transporting chemicals between floors, transport chemicals in freight elevators to avoid the possibility of exposing people on passenger elevators or in stairwells.

2 Ensure the valve protection cap is securely in place to protect the stem during transport and storage.

3 Secure and store cylinders in an upright position Use suitable racks, straps, chains, or stands to support cylinders against an immovable object, such as a bench or a wall, during use and storage Do not allow cylinders to fall, lean, or bang against one another.

4 Use an appropriate cart to move cylinders.

5 Never bleed a cylinder completely empty Leave a slight pressure to keep out contaminants.

6 Do not lubricate an oxygen regulator or use a fuel gas regulator on an oxygen cylinder Use an oxygen-approved regulator Oil or grease on the high-pressure side of an oxygen cylinder can cause

4.2.11 Unattended Operations

At times, it may be necessary to leave a laboratory, laboratory procedure, etc.unattended The following guidelines should be considered in the design of anyprocedure that will be left unattended:

1 Always check with the Laboratory Instructor or CHO to determine if it is permissible to leave a laboratory procedure unattended Where necessary and appropriate, you will be asked to develop a protocol with the Laboratory Instructor or CHO for an unattended procedure The protocol must address potential interruptions in electric, water, inert gas, and other services and provide containment for toxic substances as part of the protocol.

2 If hazardous conditions are present, post a warning notice in the vicinity of the unattended procedure and on the doors leading to the laboratory.

3 Obtain “prior approval” from the Laboratory Instructor, CHO, or Laboratory Safety Committee before leaving operations, equipment, etc., unattended.

4.2.12 Working Alone

Working alone in certain circumstances, situations, or environments may be unsafe, andrequire special arrangements with the Laboratory Instructor or CHO to ensure safety.Working "alone" for the purpose of LU’s CHP means work beyond the visual or audiblerange of another employee working in the laboratory for more than a few minutes at atime

1 If the nature of the work being performed makes an operation relatively safe (e.g., recording data, operating an instrument, clerical, others), a phone call to Public Safety informing them you will be working alone, may be adequate Confirm with the Lab Instructor, CHO, or Lab Safety Committee.

2 Work of a clearly hazardous nature (e.g., tasks involving high energy, toxic, flammable, cryogenic, high-pressure materials, compressed gases, mechanical equipment, etc.) can not be conducted alone Such activities must be scheduled during normal Laboratory hours or performed when the Laboratory Instructor or CHO is capable of providing assistance or helping in an emergency.

3 Students are not permitted to work alone when handling chemicals

4 If it is necessary to work alone, notify the Laboratory Instructor or CHO of your activities and request assistance.

5 Notify Public Safety when you leave the building or additional parties begin working in the immediate vicinity

6 Obtain “prior approval” from the Laboratory Instructor, CHO, or Laboratory Safety Committee before working alone.

4.3 Hazardous Waste Management

Safe and environmentally sound management of hazardous waste is an integral part ofthe Lesley University’s environmental management mission Failure to comply withregulatory requirements has resulted in significant fines, major liability, increased costs,and adverse publicity Lesley University is committed to meeting the stringent federal,state, and local hazardous waste regulations Responsibility for compliance withhazardous waste regulations begins with those generating waste material

In laboratories, hazardous materials that have been used and are no longer needed

may be classified as hazardous waste Because of the volume of hazardous waste

generated and accumulated by the Laboratory, it is designated as a “very small quantity”hazardous waste generator This category places numerous requirements, obligations,and restrictions on how waste must be stored, managed, etc Although beyond thescope of this program, a brief description of the critical requirements that are relevant tolaboratories is provided below

The Physical Plant Department is LU’s campus resource for management and disposal

of hazardous waste generated in laboratories Physical Plant manages the collection,processing, and disposal of chemical waste and provides resources for other hazardouswaste and environmental compliance responsibilities

Accumulation: To effectively manage hazardous waste in Laboratories, LesleyUniversity has established storage or “Satellite Accumulation Areas” (SAA) in eachlaboratory These areas are clearly labeled and delineated with hazardous waste binsfor storage of containers holding hazardous waste material pending off-site disposal

Once a hazardous material is no longer needed and will be discarded, it must never be

discharged to a drain, but must be transferred to an appropriate container and relocated

to the SAA Once the container is full, Physical Plant must be notified to arrange for thecontainer’s removal and disposal at an approved hazardous waste management facility.For more information, contact Physical Plant at 617-349-8881

5.0 Exposure Prevention and Protection

5.1 Introduction and Implementation

Lesley University utilizes various hazard prevention and control strategies to minimizeemployee exposure to toxic and hazardous substances in laboratories Methods utilized

at Lesley University include: safety engineering, administrative protocols, personalprotective equipment, and hygiene practices To ensure that the selected controlmeasures provide the designed level of protection, they must be carefully selected,effectively implemented, appropriately maintained, and properly used The followingprovides guidance for identifying, applying and maintaining appropriate exposureprevention and control strategies for laboratory procedures, chemicals, and methods Additional Exposure Prevention and Protection methods will be included as they areidentified or implemented The two criteria that will be addressed include a description ofthe device or equipment and the measures used to ensure they are functioning properly,

as well as specific measures that will be taken to ensure proper and adequateperformance and maintenance

5.2 Fume Hoods

A chemical fume hood is an important engineering method for controlling exposure tohazardous materials In conjunction with sound laboratory techniques, a chemical fumehood serves as an effective means of capturing airborne contaminants that wouldotherwise enter the general laboratory environment Although not a substitute forpersonal protective equipment, the chemical fume hood sash, when lowered, also forms

a physical barrier to protect laboratory workers from hazards such as chemical splashes

or sprays, fires, and minor explosions Chemical fume hoods may also provide effectivecontainment for accidental chemicals spills, although this is not their primary purpose

A well designed fume hood, when properly installed and maintained, can provide asubstantial degree of protection for the user, provided its proper use and limitations areunderstood Characteristics to consider in determining the applicability of fume hooduse include: physical state, volatility, toxicity, flammability, eye and skin irritation, odor,and the potential for producing aerosols

5.2.1 Procedures Requiring Fume Hoods: A fume hood will be used if a chemicalprocedure exhibits any of the following characteristics:

1 Airborne concentrations might approach an occupational exposure limit (e.g., OSHAaction level or permissible exposure limit);

2 Flammable vapors might approach 10% of the lower explosion limit,

3 Materials of unknown toxicity are used, handled or generated, or

4 The odor is annoying to laboratory personnel or areas adjacent to the laboratory

If the appropriateness of fume hood use cannot be determined, it is best to utilize theequipment

5.2.2 Optional Fume Hood Use: Each procedure should be evaluated for its potential toproduce, release, or increase the volatility of chemicals or aerosols Procedures thatcan generally be carried out safely outside the fume hood involve:

1 Water-based solutions of salts, dilute acids, bases, or other reagents,

2 Very low volatility liquids or solids,

3 Extremely small quantities or concentrations of otherwise problematic chemicals,and

4 Closed systems that do not allow significant escape of vapors, fumes, aerosols, etc.,

to the laboratory environment

5.2.3 Special Precautions: In specialized cases, fume hoods will contain exhausttreatment devices, such as water wash-down systems for perchloric acid use, orcharcoal or HEPA filters for removal of particularly toxic or hazardous materials Contact

a Certified Industrial Hygienist for assistance determining if special precautions arenecessary

5.2.4 Fume Hood Work Practices: See Section 4.2.3, Safety Guidelines (“StandardSafety Practices”)

5.2.5 Fume Hood Performance: Proper maintenance and functional testing will ensurethe fume hood provides an adequate degree of performance and safety LesleyUniversity will take the following action to ensure fume hoods are effective:

• Storage of apparatus, chemicals, bottles, anything, other materials and substancesinside fume hoods must be minimized;

• Fume hoods will be tested annually to ensure that they maintain adequate capturevelocity and air flow volume; and

• Labels will be affixed to the hoods indicating the appropriate sash height to achieve

an acceptable capture velocity

Chemical fume hood performance is also dependent on the room's air flow pattern,including airflow generated by drafts and persons walking by Minimize traffic andopening and closing of doors near the chemical fume hood When the chemical fumehood is in use, the sashes should be pulled down as far as workable for minimalexternal airflow interference and maximum barrier protection Chemical fume hoodsused for hazardous chemicals shall have an average face velocity of 80 to 100 feet perminute (fpm) at a minimum sash height of twelve inches Face velocity should notexceed 120 fpm at the working sash height

5.2.6 Fume Hood Performance Evaluation

The CHO is responsible for scheduling and managing the fume hood-testing program.S/He will arrange for needed repairs as appropriate, and maintain the documentation ofthe annual fume hood testing Chemical fume hoods must also be evaluated forperformance upon installation and following any alterations, modifications, etc TheLaboratory Instructor or CHO must notify the Physical Plant of new installations or

5.3 Safety Shields (Fume Hood Sash)

“Sash” is the term used to describe the movable glass panel that covers a fume hoodface area Sashes can be vertical, horizontal, or a combination of the two Many hoodsare installed with a sash stop, which stops the sash at approximately a 14 inch worklevel Sash stops should never be removed, overridden, or modified It is recommendedthat all lab work in a properly functioning fume hood be performed at the sash stop level

or lower whenever possible

Safety shields must be properly positioned and used when working with concentratedacids, bases, oxidizers or reducing agents, because of their potential for suddenspattering or even explosive release of material Other times safety shields are requiredinclude: reactions carried out at non-ambient pressures (vacuum or pressure), first timereactions or reactions involving extremely volatile materials under normal conditions 5.3.1 Safety Shields Inspection: When Safety Shields are provided they will be visuallyinspected before and after each use to ensure that they provide the designed level ofprotection This visual inspection will consist of the following:

• Sash moves and operates freely

• Glass is clean, and contains no cracks, scores, or damage that may serve toweaken its protective abilities

5.4 Safety Shower and Eye Wash

5.4.1 Introduction: Safe operations, effective communication, and personal protectiveequipment are Lesley University’s primary methods of protecting laboratory personnelfrom exposure to hazardous chemicals Lesley University will reference the latestedition of ANSI Z358.1, “Emergency Eye Wash and Shower Equipment” for the properselection, installation and maintenance of this equipment Where provided, emergencywashing facilities will meet the requirements of the latest edition of ANSI Z358.1.Emergency facilities will be provided in locations where the eyes of any employee may

be exposed to “corrosive” materials All such facilities will be located where they areeasily accessible in an emergency

5.4.2 Inspection and Activation: Safety showers and eyewashes will be activated weeklyand inspected at least annually to assure conformance with ANSI Z358.1 Physical

Plant conducts the annual inspection and maintains related records Contact the Physical Plant to schedule safety-shower testing if the shower has not been inspected

in the previous 12 months ANSI Z358.1-2014 recommends the following EW/SSevaluations:

Annual Inspection: Inspect units annually to assure proper conformance with the ANSI

requirements.

Weekly Activation: Flush the lines and verify proper operation; weekly activation of plumbed units – long enough to verify operation and assure fluid is available and to clear any sediment build-up.

Self-Contained Units: Check self-contained units by following the manufacturer’s

recommendations; weekly for units using tap water, or 3-6 months if tap water is mixed with a manufacturer’s preservative Self-contained eyewash units should be drained completely, disinfected, and rinsed prior to refilling.

Factory-sealed cartridges / bottles: Follow the expiration date of the cartridge / bottle.

5.4.3 Training: All Laboratory Personnel will be instructed in the location(s) and use ofthe safety shower and eyewash During training, where possible, Laboratory Personnelwill be encouraged to activate the eye wash and experience the flushing procedure.This may further encourage them to utilize appropriate preventive measures andavailable personal protective equipment

5.4.4 Hazardous Locations: Flammable-liquid storage cabinets, other hazardousequipment or materials shall not be placed near a safety shower or eye wash, andaccess to the shower / eyewash or the activating handle shall not be impeded The areasurrounding a shower / eyewash shall be provided with a 34-inch-diameter clear area.5.5 Personal Hygiene

Personal hygiene is extremely important for those working in a laboratory Consumption

of chemically contaminated food, beverages, or smoking materials is a potential route ofexposure to toxic chemicals through ingestion Thus, laboratory personnel shall notprepare, store, or consume food or beverages; pipette by mouth; smoke; apply lip balm

or cosmetics; or handle contact lenses in the laboratory This elementary safety ruleshall be followed by everyone working in or visiting a laboratory

5.5.1 Hand Washing: Hand washing is a primary safeguard against inadvertentexposure to toxic chemicals Always wash hands after removing soiled protectiveclothing, before leaving the laboratory, even if gloves were used, and before eating,drinking, smoking, or using the rest room Hands should also be washed periodicallyduring the day at intervals dictated by the nature of the laboratory work Wash with soapand running water, with hands held downward to flush the contamination off the hands.Turn the tap off with a clean paper towel to prevent recontamination, and dry your handswith clean towels

5.5.2 Additional Hygiene Practices: When in the laboratory, confine long hair and looseclothing to keep them from catching fire, dipping into chemicals, or becoming entangled

in moving machinery Avoid wearing finger rings and wrist watches which may becomecontaminated, react with chemicals, or be caught in equipment moving parts

Remove personal protective equipment (e.g., laboratory coats, gloves, etc.) beforeleaving the laboratory to prevent spreading contamination to other areas Keep a clean,spare coat to wear outside the laboratory Do not wear gloves outside the laboratory.5.6 Personal Protective Equipment (PPE)

5.6.1 Introduction: When properly selected and worn, PPE can reduce the risk ofchemical exposure by physical contact, inhalation or ingestion of a toxic substance.Selection of appropriate PPE should be based on an evaluation of the operationalhazards and such information as: the chemicals handled, their concentration, operationsperformed, etc Laboratory Instructors and the CHO will conduct a hazard assessment

of each laboratory to identify and specify the appropriate PPE Appendix A provides ahazard assessment guide for evaluating and identifying appropriate PPE At a minimum,while in Lesley University laboratories, Laboratory Personnel will wear the followingminimum appropriate PPE:

• Eye Protection

• Appropriate Foot Wear

• Latex or nitrile gloves (when required)

• Lab coats are not necessary for all procedures, but may be required by thefaculty or CHO and will be available upon request

• Other equipment as deemed appropriate by the Laboratory Instructor or CHO

5.6.2 Contact Lenses Use: Contact lens use is permitted on a case-by-case basis.Procedures requiring removal of contact lenses will be announced in advance, withample time permitted for the removal
