Possible Solutions

Styrene exposure is best controlled through the use of engineering and work practices. Some operations (e.g., certain open molders using manual techniques) have shown that engineering and work practice controls are not practical for limiting exposure below 100 ppm.

Hazard Recognition

Health effects of styrene include irritation of the skin, eyes, and the upper respiratory tract. Acute exposure may also result in gastrointestinal effects. Chronic exposure affects the central nervous system showing symptoms such as depression, headache, fatigue, weakness, and may cause minor effects on kidney function. The following references aid in recognizing occupational hazards and health effects associated with styrene.

Evaluating Exposure

Overview

Styrene is primarily a synthetic chemical that is used extensively in the manufacture of plastics, rubber, and resins. It is also known as vinylbenzene, ethenylbenzene, cinnamene, or phenylethylene. Many workers, including those who make boats, tubs, and showers, are potentially exposed to styrene. Health effects from exposure to styrene may involve the central nervous system and include complaints of headache, fatigue, dizziness, confusion, drowsiness, malaise, difficulty in concentrating, and a feeling of intoxication..
