Safety Standards for Signs, Signals, and Barricades

The Occupational Safety and Health Administration (OSHA) is issuing a direct final rule amending construction industry standards to require that traffic control signs, signals, barricades or devices protecting construction workers conform to Part VI of either the 1988 Edition of the Federal Highway Administration (FHWA) Manual on Uniform Traffic Control Devices (MUTCD), with 1993 revisions (Revision 3) or the Millennium Edition of the FHWA MUTCD (Millennium Edition), instead of the American National Standards Institute (ANSI) D6.1-1971, Manual on Uniform Traffic Control Devices for Streets and Highways (1971 MUTCD). This action is consistent with OSHA's June 16, 1999 interpretation letter stating that the agency would allow employers to comply with Revision 3 in lieu of the 1971 MUTCD.
