TITLE OF WORK: METHOD STATEMENT MVAC 23 APRIL 2015 FOR COOLING TOWER ASSEMBLY AND INSTALLATION 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 2.18 MITIGATION OF RISK Impact damage during pouring of concrete installation to be monitored constancy white concrete is poured Correct connections or materials, ensure the final installation and connections are inspected and signed off with photographic records
