2.16 ATTENDEES

2.16.1 Sub-contractor manager

2.16.2 Sub-contractor site manager

2.16.3 Main contractor MEP coordinator

2.16.5 HKL M&E manager.

2.17 SAFETY BRIEFING

2.17.1 Safety shall be in first priority during construction, safety staff shall be present on site all the time tosupervise and to remind workers to observe safety requirement Stop work order shall enforce once its dose not meetthe safety requirements

2.17.2 Safety shall conform strictly observed All workers and staff on site shall be oriented of safety requirements.All safety equipment such as cloths , shoes, helmet , gloves , safety belt should provide and regularly checked duringconstruction

2.17.3 The engineer shall inspect all subcontractor tools prior to be used on site

2.17.4 Safety Supervisor shall be present for all the safety site inspection

2.17.5 For the safety of worker, grounding wire for the electric ARC process must be provided and wet cloths,protective glasses, long sleeve cloth must be imposed to worker

2.17.6 Fire extinguisher shall be provided at welding area and safety provision must done to ensure usageworkability

2.17.7 Safety working with Scaffolding

2.17.7-1 All scaffolds must be erected under the supervision of a competent and experienced person- usually theconstruction superintendent This includes moving scaffolds from one position to another Each leg of a scaffoldmust be supported by and adequate footing Loose bards, bricks and other material do not provide a safe, adequatebase

2.17.7-2 Where the working platform in more than 10 feet off the ground, the scaffold shall have guardrailsinstalled

2.17.7-3 If people are working under the scaffold, toe boards must be used to prevent tools and materials fromfalling on them

2.17.7-4 Workers are not to climb the metal tubular frame of the scaffold to get the working platform Other, safermeans of access must be used – a ladder or access from the building

2.17.8 Safety working with Mobile Scaffold

2.17.9 Mobile scaffolds have restricted reach unless a guy wire secures them They are more susceptible tooverturning and require a smooth, level working surface A complete guardrail system must be used at elevationsabove 10 feet and shall be used at all working levels Scaffold should be moved when unoccupied and only bypushing from the base Wheel brakes must be set when scaffold is in use

-Impact damage during pouring of concrete installation to be monitored constancy white concrete is poured Correctconnections or materials, ensure the final installation and connections are inspected and signed off withphotographic records by MEP coordinator on site M&E staff from contractor, architect and client
