What is the most effective method for controlling a workplace hazard?

The most effective method for controlling a workplace hazard is the elimination of the hazard at the source. This approach is fundamental in workplace safety because it directly removes the risk, rather than just addressing the symptoms or consequences of the hazard. By eliminating the hazard, there is no longer any chance for exposure or harm to employees, which significantly reduces the risk of accidents and injuries.

In contrast, other methods, such as relocating workers, do not eliminate the hazard but merely transfer the risk to a different location. Increased supervision may help ensure that safety procedures are followed, but it does not remove the underlying hazard itself. Providing personal protective equipment is important for protecting workers, but it is more of a secondary measure that relies on individuals consistently using the equipment correctly. These approaches are useful and necessary in certain contexts, but they do not achieve the same level of safety as directly eliminating the hazard at its source.
