Employers should use the hierarchy of controls to control hazards and protect workers, including by first trying to eliminate hazards from the workplace, then implementing engineering controls followed by administrative controls and safe work practices, and finally using personal protective equipment (PPE). When engineering controls, such as physical barriers, are not feasible in a particular workplace or for a certain operation, other types of controls, including PPE, may be considered in accordance with the hierarchy.
