acceleration of the aging process, or whether they will cause only significant discomfort
c. Evaluation. Evaluation of the magnitude of the environmental factors or
stresses arising in or from the work place is essential in order to predict the probable
effect on health and well being. The industrial hygienist, by virtue of training and
experience and aided by quantitative measurements of the chemical, physical energy,
biological, or ergonomic stresses, can render an expert opinion as to the "healthfulness"
of the environment, either for short periods or for lifetime exposure.
d. Prescription of Corrective Procedures. When necessary to protect health,
control measures are based on a good evaluation of the environmental factors of
stresses. Among control measures most frequently used are:
Isolation of a process or work operation to reduce the number of persons
Substitution of a less harmful material for one that is more dangerous to
Alteration of a process to minimize human contact..
Ventilation and air cleaning to provide an atmosphere safe for human
(5) Reduction of exposure to radiant energy by shielding, increasing
distance, and limiting time.
(6) Wet methods to reduce emission of dusts to the atmosphere such as in
abrasive blasting, lathing, and grinding operations.
(7) Good housekeeping, including cleanliness of the work place, proper
waste disposal, adequate washing, toilet and restroom facilities, healthful drinking water
and eating facilities, and control of insects and rodents.
(8) Personal protective devices to be worn, such as special clothing, eye,
hearing, and respiratory protective equipment.
ESSENTIAL INDUSTRIAL HYGIENE PROGRAM ELEMENTS
The items listed in this paragraph are the minimum essential elements required
for an installation IH program. The elements listed are required by Federal law, AR, and
policy or are based upon consensus standard and good IH practice. Figure 1-1 is a
possible IH health hazard.
