1-11. Health Hazards. A variety of ingredients used in the manufacture of paint materials are
injurious to the human body in varying degrees. While the body can withstand nominal quantities of
most of these poisons for relatively short periods of time, continuous exposure or overexposure to them
may have harmful effects. Furthermore, continued exposure to some material may cause the body to
become sensitized so that subsequent contact, even in small amounts, may cause an aggravated reaction.
To this extent, these materials are a very definite threat to the normally healthy individual and a serious
danger to persons with chronic illnesses or disorders.
a. Causes of Health Hazards. Hazardous materials are divided into two major groups; they are
toxic materials and dermatitic (skin-irritating) materials.

and may enter the body either by breathing, swallowing, or absorbing through the skin. Possible
symptoms of excessive exposure are irritation of the nasal
