explain the concept of hierarchy of control measures?

The hierarchy of control measures is a systematic approach used to minimize or eliminate hazards in the workplace. It prioritizes control strategies from most effective to least effective: elimination of the hazard, substitution with safer alternatives, engineering controls, administrative controls, and personal protective equipment (PPE). This framework emphasizes addressing risks at their source and encourages the implementation of the most effective measures first to ensure worker safety. By following this hierarchy, organizations can create safer work environments and reduce the likelihood of accidents and injuries.
