Major Accident Hazard Management in Construction Projects

A major accident hazard is a source of danger that has the potential to cause a major incident, whether that involves multiple fatalities and/or significant damage to machine, equipment or the environment. Managing major accident hazards is vital to safe operations. In construction projects, the main contributors for major incidents are from sloping and shoring in excavation works, formwork structure in cast-in-situ concrete and working at height in access scaffolds. It is critical to put in place arrangements for the control of major accident hazards and to limit the consequences to people and the environment of any that do occur.
