Hazard Locations and Solutions

Although extremely low frequency (ELF) exposures occur everywhere, potentially hazardous exposure depends on the strength of the ELF fields at the source, the distance from the source, and possibly the duration of exposure. The following references describe where significant exposures may occur and may be useful in identifying significant exposures and possible solutions.

  • EMF (Electric and Magnetic Fields). National Institute for Occupational Safety and Health (NIOSH) Workplace Safety and Health Topic.
  • EMFs in the Workplace. U.S. Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 96-129, (1996). Also available in Spanish. Answers frequently-asked questions about extremely low frequency (ELF)- electric magnetic fields (EMFs) in the workplace and helps identify EMF sources at work and suggests simple steps for reducing exposures.
  • Electric & Magnetic Fields. National Institute of Environmental Health Sciences (NIEHS), National Institutes of Health (NIH). Provides links to EMF health effects, results of EMF research and EMF Questions and Answers.
