Engineering controls include eliminating toxic chemicals and substituting
non-toxic chemicals, enclosing work processes or confining work operations,
and the installation of general and local ventilation systems.
Work practice controls alter the manner in which a task is performed.
Some fundamental and easily implemented work practice controls include (1)
changing existing work practices to follow proper procedures that minimize
exposures while operating production and control equipment; (2) inspecting
and maintaining process and control equipment on a regular basis; (3) im-
plementing good housekeeping procedures; (4) providing good supervision;
and (5) mandating that eating, drinking, smoking, chewing tobacco or gum,
and applying cosmetics in regulated areas be prohibited.
Administrative controls include controlling employees' exposure by
scheduling production and tasks, or both, in ways that minimize exposure le-
vels. For example, the employer might schedule operations with the highest
exposure potential during periods when the fewest employees are present.
When effective work practices or engineering controls are not feasible or
while such controls are being instituted, appropriate personal protective
equipment must be used. Examples of personal protective equipment are
gloves, safety goggles, helmets, safety shoes, protective clothing, and respira-
tors. To be effective, personal protective equipment must be individually se-
lected, properly fitted and periodically refitted; conscientiously and properly
worn; regularly maintained; and replaced, as necessary.
