This document discusses risks associated with installing metal sheets on a roof for a football stadium. It identifies hazards at each step: transporting metal sheets, laying sheets, and installing sheets. Hazards include sheets falling, overloading machinery, ruptures causing injury, slipping, equipment mishandling, electric shock, and metal splinters. For each hazard, it assesses risk level and proposes risk reductions like safety equipment, training, and monitoring. The overall goal is a risk assessment process to identify, assess, reduce, implement, and monitor risks to achieve acceptable residual risks.
