Hierarchy of controls and inherently safe design.
American Industrial Hygiene Conference and Exposition, May 21-26, 2005, Anaheim, California. Fairfax, VA: American Industrial Hygiene Association, 2005 May; :1
Industrial hygienists have become very proficient in the implementation of ventilation, administrative, and personal protective equipment controls. When considering and designing exposure controls, however, industrial hygienists sometimes skip over the top of the hierarchy of controls, perhaps because of the perception that these types of controls are too difficult or too expensive to implement. Elimination and substitution deserve a closer look, not only because they increase the level of protection afforded to the worker and the work environment, but also because they can better control environmental pollution concerns that may be overlooked with the use of ventilation or personal protective equipment. In many cases, elimination or substitution controls are also less expensive and lower maintenance alternatives to other types of controls over the long term. A number of examples and case studies will be presented that demonstrate the thought process involved in designing controls that more effectively eliminate the exposure hazard to the worker, the workplace, and the environment.
