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.

  • Styrene. National Institute for Occupational Safety and Health (NIOSH), (May 1994). Provides an Immediately Dangerous to Life or Health (IDLH) document that includes acute toxicity data for styrene.
  • Criteria for a Recommended Standard: Occupational Exposure to Styrene. U.S. Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 83-119, (September 1983).
