The purpose of a respirator is to prevent the inhalation of harmful airborn
e substances or to provide a source of respirable air when breathing in oxy
gen-deficient atmospheres. For a physician to recommend the use of respirat
or general background information on respiratory-protective devices is requ
ired. The first part of this clinical practice review describes the general
aspects of industrial hygiene respirators and a respirator-certification p
rogram. The second part addresses matters related to medical certification
for respirator use.
Medical certification for respirators is an important part of the activitie
s of the occupational physician. To determine whether a worker is able to t
olerate the added strain of a respiratory protective device is a complex pr
ocess in which factors such as fitness for work, health of the individual,
characteristics of the work itself and the properties, type, and requiremen
ts of the respiratory protective device, have to be considered. Medical cer
tification is of utmost importance for respirator use, and it should be vie
wed as an element in a comprehensive respiratory protection program. A comp
rehensive program is the key element in affording the workers' effective re
spiratory protection once the initial steps of the hierarchy of methods of
hazard control have proved insufficient or infeasible. As a result, the nee
d for the industrial hygiene/safety officer the worker; the employer and th
e medical professional to work as a team is much more than in any other fie
ld of occupational medicine-a necessary requirement for making the right de
cision. Am. J. Ind. Med. 37:142-157, 2000. (C) 2000 Wiley-Liss, Inc.
