The HSE plan summarizes the key health and safety requirements for erecting new crude oil storage tanks at an oil refinery in Kavala, Greece. It defines 3 main objectives: 1) outline the theoretical background of HSE, including definitions of safety, health, and environment, and causes of accidents; 2) present the HSE policy and responsibilities of contractors, supervisors, and engineers; 3) provide guidelines on specific safety measures for work involving elevations, electricity, lifting devices, welding, confined spaces, and excavations. The plan aims to ensure work is completed according to Greek legislation and that risks are properly managed to avoid accidents and protect workers.
