No respirator provides total protection or provides the wearer a guaranteed zero-exposure level. The primary objective of a respirator is to reduce a worker's inhalation exposure from a level that is considered hazardous to a level that is considered safe. However, a respirator cannot do its job if it is not being worn during all times of exposure. Not wearing the respirator for even short periods during exposure will reduce protection. Two ways to reduce this risk during contaminant exposure include training respirator wearers on the effects of removing their respirator prematurely, and allowing them to select a respirator that is more suitable for them and their application.
