NEMA Releases New Standard on Exit Sign Visibility
September 10, 2003
(ROSSLYN, VA) - The Emergency Lighting Section of NEMA, the National Electrical Manufacturers Association, has released EM 1-2002, Exit Sign Visibility Testing and Requirements for Safety.

The purpose of this publication is to promote safety by setting forth visibility testing procedures and requirements for exit signs. These procedures and requirements are based on the best available objective research by the National Institute of Standards and Technology and the Lighting Research Center and on independent testing by CSA International.

EM 1-2002 contains performance requirements and test methods for evaluating exit sign visibility, which includes readability and the ability to attract attention in an emergency.

"During the past few years, NFPA and UL have allowed minimum visibility requirements for exit signs to degrade to the point where many authorities believe the signs no longer meet the need to be readily visible in order to help occupants evacuate a building," said Billy Helton, chairman of the Emergency Lighting Section. "EM 1 is an important document because it sets minimum visibility requirements for exit signs that are very cost effective and readily available. These requirements also allow better harmonization with CSA exit sign visibility requirements."

EM 1-2002 may be purchased for $51.00 by visiting or by contacting Global Engineering Documents at (800) 854-7179 (within the U.S.), (303) 397-7956 (international), or (303) 397-2740 (fax).
