of floors as below: 2.15 SCHEDULE OF INSPECTION/T&C FORM Refer to ITP form as the attached file in below 2.16 ATTENDEES 2.16.1 Sub-contractor manager 2.16.2 Sub-contractor site manager 2.16.3 Main contractor MEP coordinator MVAC Services Page PROJECT: EXCHANGE SQUARE (STREET 106 SITE) TITLE OF WORK: METHOD STATEMENT MVAC 11 APRIL 2015 FOR DUCT & PIPE INSULATION -2.16.4 Main contractor mechanical engineer 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 to supervise and to remind workers to observe safety requirement Stop work order shall enforce once its dose not meet the 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 during construction 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 usage workability 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 the construction superintendent This includes moving scaffolds from one position to another Each leg of a scaffold must be supported by and adequate footing Loose bards, bricks and other material not provide a safe, adequate base 2.17.7-2 Where the working platform in more than 10 feet off the ground, the scaffold shall have guardrails installed 2.17.7-3 If people are working under the scaffold, toe boards must be used to prevent tools and materials from falling on them 2.17.7-4 Workers are not to climb the metal tubular frame of the scaffold to get the working platform Other, safer means 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 to overturning and require a smooth, level working surface A complete guardrail system must be used at elevations above 10 feet and shall be used at all working levels Scaffold should be moved when unoccupied and only by pushing from the base Wheel brakes must be set when scaffold is in use MVAC Services Page PROJECT: EXCHANGE SQUARE (STREET 106 SITE) TITLE OF WORK: METHOD STATEMENT MVAC 11
