PAPR use is prior training. A formalized training
process with periodic refresher training is recom-
mended, including instruction in donning and
removal, and several hours of clinical simulation.
7.11 Conclusion
Respiratory protection equipment is recommended
at Level B when substances are unknown or
potentially in high concentration, and Level C
when lesser threats are present. Studies have
demonstrated large reductions in particulate levels
and chemical off-gassing, once outer clothing
is removed; especially after washing with soap
and tepid water [10]. Patients decontaminated
pre-hospital should pose minimal risk to hospital
workers assuming clothes are removed and skin is
washed. The major exception to this rule occurs
when highly persistent military chemical agents are
employed. Residual agent may continue to pose
a small threat to hospital personnel until a more
thorough process is completed. The powered air-
purifying respirator (PAPR), equipped with both
particulate and chemical filters should serve most
hospital based scenarios.
