The National Institute for Occupational Safety and Health
(NIOSH) and other government agencies do not consider EMFs a
proven health hazard. Because some studies have associated high
magnetic field exposures with increased cancer risks, the
government will continue studying EMFs. While
research continues, concerned workers and employers might
consider the following simple, inexpensive measures for reducing
Inform workers and employers about possible hazards of
Increase the worker's distance from the EMF source. Since
magnetic fields often drop off dramatically within about 3
feet of the source, workers can stand back from electrical
equipment, and work stations can be moved out of the 3-ft
range of stronger EMF sources.
Use low-EMF designs wherever possible (for the layout of
office power supplies, for example).
Reduce EMF exposure times. No action should be taken to reduce
EMF exposure if it increases the risk of a known safety or
health hazard such as electrocution.
