In the not-too-distant past, it was common for Occupational Safety and Health professionals to consider the hierarchy of controls according to the following priority order:

1. Engineering controls,

2. Administrative controls

3. Personal Protective Equipment

However, eliminating the hazard and substitution have usurped engineering control's position at the top of the hierarchy although they have always been obvious best options, just not always included in discussions of the hierarchy of controls. Identify two examples where elimination of the hazard or substitution was, or might be, applied as a means of hazard control. Discuss some of the pros and cons of this option as compared to the other options in the hierarchy. You may also select examples from places you have worked or for which you have some familiarity.
