Final answer:
Yes, engineering controls are preferred over PPE for controlling exposure to hazards because they address the hazard at the source and provide a higher level of protection by not relying on worker behavior.
Step-by-step explanation:
In the hierarchy of hazard control, engineering controls are indeed more preferred than personal protective equipment (PPE) for controlling exposure to hazards. Engineering controls aim to eliminate or reduce the hazard at the source, before it comes into contact with workers. Examples of engineering controls include the use of isolation, ventilation, and enclosures.
Engineering controls can often provide a higher level of protection because they do not rely on worker behavior and can potentially eliminate the hazard from the workplace. On the other hand, PPE is considered a last line of defense and should be used when engineering controls cannot adequately control the hazard or during the time engineering controls are being developed. PPE is crucial but is accepted as a less preferred method because it does not eliminate the hazard and its effectiveness depends on correct selection, fit, and use by the workers.
