What is first choice to reduce and eliminate a hazard?

The first choice to reduce and eliminate a hazard is to implement engineering controls, which involve redesigning equipment or processes to minimize risks. This can include substituting hazardous materials with safer alternatives, enclosing processes, or using safety guards. If engineering controls are insufficient, administrative controls and personal protective equipment (PPE) can be employed as secondary measures. Ultimately, the goal is to prioritize solutions that eliminate the hazard at its source.
