SEALING OF VENT HOLES ON HANDRAILS AFTER INSTALLATION

1.0 PURPOSE

1.1 The purpose of this method statement is to describe the sequence of work and safety precautions to be observed to ensure that the sealing work of vent holes on handrails after installation shall be performed in accordance with the project specification and safety standard of commercial buildings, plants and refinery projects.

2.0 SCOPE

This method statement will describes the works processes in sealing of vent holes on handrails of steel structure at commercial buildings, plants and refinery projects after installation using epoxy steel resin since seal welding after installation is not practical (12-SAMSS-007, sec. 6.2.6.8). The procedure to be applies to all vent holes on handrails at different elevation. Execution of work shall be carried out safely and in accordance with the relevant project specifications and safety standard.
