assemblies shall be decontaminated in accordance with manufacturers
recommendations; and

3.06 AIR PURIFYING RESPIRATORS;
A. Supply a sufficient quantity of HEPA respirator filters so that workers can change filters at any
time that flow through the face piece decreases to the level at which the manufacturer
recommends filter replacement. Require that regardless of flow, filter cartridges must be
replaced after 40 hours of use. Require that HEPA elements in filter cartridges be protected
from wetting during showering. Require entire exterior housing of respirator, including blower
unit, filter cartridges, hoses, battery pack, face mask, belt, and cords, be washed each time a
worker leaves the Work Area. Caution should be used to avoid shorting battery pack during
washing. Provide an extra battery pack for each respirator so that one can be charging while
one is in use.
