- Microclimate with 100% Sample reached the Hygiene Standard

- Light: % samples not reach the standard reduced;

- Noise: % of samples not achieve the standard increased from 0 to 11.4%

II THE REALITY OF LABOR ENVIRONMENTAL

CONTAMINATION

2 Data of weight dust, lead dust, lead gas, acid gas measured from 2009-2011

- The rate % Sample reached the Hygiene Standard: Acid gas with 100%

- The rate % Sample not reach the Hygiene Standard

Lead dust, lead gas : 100%,

Dust weight: be increasing

II THE REALITY OF LABOR ENVIRONMENTAL

Lead dust and lead vapor from

2009 to 2011 % samples not reach the Standard did not change

4 Conclusion about the reality of labor environmental pollution

Noise: increase Light: decrease

Weight dust, lead dust, lead gas: increase

is very high

1 Lead dust: 100% samples exceed the allowed Hygiene Standard with the reliability α = 0,10

2 Lead vapor: 60% samples exceed the allowed Hygiene Standard with the reliability α

= 0,10

II MANAGING EMPLOYEES’ HEALTH

1 The result of periodically health examine at GS

Company

- Percentage % as per the health classification of

employee did not fluctuate considerably

2 Statistics on disease situation of employees through

periodically health examine.

- Periodontal disease occupied the highest rate

→ respiratory tract is the primary route of exposure

II MANAGING EMPLOYEES’ HEALTH

3 Survey and interview results

A Awareness of the environmental factors affecting health is temperature highest rate

B The illness reality of employees during the first six months of the year is backache highest rate

C Employees’ awareness in using personal protective equipment from 70-100%

IV THE REALITY OF HEALTH, ILLNESS OF EMPLOYEES

Company :

 Protected employees’ health good

Equipped the personal protective equipment for workers good

 Awareness of health protection for themselves is high

 Reducing the rate of inorganic lead infection over time from 2009 to 2011.

Company

Occupational illness for employees

Discovering the occupational diseases soon

Minimize the cause of career illness

SUMMARY AND PROPOSALS

A SUMMARY

I ENVIRONMENTAL MANAGEMENT

1.1 Management of labor hygiene

- To labor environment: factors exceeded the Standard of Labor Hygiene as following:

1 Lead dust: 100% samples

2 Lead vapor: 60% samples

3 Weight dust: 21.5% samples

4 Noise: 13.9% samples

I ENVIRONMENTAL MANAGEMENT

1.2 Evaluation of environmental risks

Company should manage well:

receiving the exposure with contaminants at current and

in future

II MANAGEMENT OF HEALTH

1 To employees

The reality of illness in 2011:

- Molar and face is highest eyes Otorhinolaryngology

2 Evaluating the health risks

-The rate following of inorganic infection and inorganic lead

infection decreased from 2009 to 2011

=> People who have lead infected symbols need to be treated and stop contacting or change working position.

II MANAGEMENT OF HEALTH

3 The control comparison

- Workers who contacted directly (317 people) and indirectly (22 people) with lead vapor

The danger of infection at directed department is very high because they contact with lead vapor and dust weight every day By the time the lead content accumulates in the environment or imbues in their bodies will be increased

 Company needs to have nutrition and protection for their workers, and rotates the work for people who may have a high risk for lead infecting

Company needs:

1 The technological process should be closed

2 Increase the productivity of sucking of partial stuck system

3 Chemicals should be maintained in closed containers with label in particular area

4 Automate the manufacturing process of chemicals

5 Workers working should have personal protective equipment

PETITION

6 Workers should be equipped with good comforters suitable to each kind of work and avoid reusing the old comforters

7 Limiting the spreading out lead in living environment surrounding

8 It is forbidden to put food, drink, and cigarettes near the manufacturing areas

9 Having a regimen to improve worker health

10 Pay special attention to prevent and fight fire

PETITION

A SOLUTIONS FOR REDUCE ENVIRONMENTAL POLLUTION.

1 Training and upgrading the employees’ awareness

2 Planning the manufacturing area

3 Measures of technology

4 Managing waste water

5 Managing the solid waste

6 Managing the air pollution

7 Proposals for regulations and policies

PROPOSE SOLUTIONS

B SOLUTIONS FOR MANAGING WORKERS’ HEALTH.

Measures of health

1 Organize to examine in recruitment

2 Periodically health examine

3 People who have signals in infecting lead should

be treated, stopped working and changed their job

B SOLUTIONS FOR MANAGING WORKERS’ HEALTH

Individual methods

1.Employees should be equipped to use personal protective equipment

2.Having shower after working

3.Not allowed smoking at work

4.Clean dental hygiene
