Major safety inspection focuses are whether the construction procedures comply with the work plan and whether the installation process rise to unsafe condition. Figure 2: Weekly cycle
Process safety discussion Process safety discussion provides platform to discuss and solve problems which are identified during the safety inspection and hazards identification activities. Moreover, safety discussion is arranged daily at fixed time and safety officer reviews safety performance of the day.
Monthly SWC Monthly SWC is carried out to review the site performance and progress, to improve the workers' safety awareness through training and reward schemes, and to recognize their commitment and cooperation. Prepared by: Mark Anthony P. Taton
