OSHA June 13 issued a direct final rule to update the construction signage standards by adding references to the latest versions of American National Standards Institute (ANSI) consensus standards on specifications for accident prevention signs and tags. The rule retains the existing references to the earlier ANSI standards, which allows employers the option to either comply with the updated or earlier standards.

The rule also incorporates, by reference, Part VI of the Manual of Uniform Traffic Control Devices (MUTCD), 1988 Edition, Revision 3, into the construction standards. 

The rule becomes effective Sept. 11, 2013, unless OSHA receives significant adverse comments. Comments on the direct final rule must be submitted by July 15, 2013.
