In November of 2015 the EPA updated and revised its regulations regarding agricultural workers, pesticide handlers and other persons under the Worker Protection Standard (WPS).  This regulation covers many aspects on the safe use and handling of pesticides for agricultural use.

The regulation requires that pesticide product labels specify a respirator that is to be used with the respective product.  When a respirator is required by the pesticide product labeling, the handler must ensure that certain elements of 29 CFR 1910.134 Respiratory Protection be complied with.  It requires that fit testing, training and medical evaluations be performed in accordance with 1910.134.  Although the EPA regulation does not explicitly state that all the elements of the OSHA Respiratory Protection standard be complied with, it is certainly recommended that the user do so, and should also check with local, state and federal regulators for further guidance.

Affected Industries or General Applications:
