Safety Concerns Raised by the Firefighting
Community Regarding High-Visibility Safety
Apparel Result in Modification to Vest Rule
November 21, 2008 -- The Federal Highway Administration (FHWA) today issued an Interim Final Rule to
address safety concerns raised by the firefighting community regarding high-visibility safety apparel (see
Worker Visibility Final Rule - 23 CFR Part 634, below).
The Interim Final Rule:
Revises the definition of “worker” to exclude firefighters when they are exposed to flame, fire, high heat or
hazardous materials.
Exempts firefighters from the requirement to use high-visibility safety apparel, as defined in this rule, when
they are exposed to hazardous conditions where the use of such apparel may increase the risk of injury to
firefighter personnel.
The Interim Final Rule is available at
Worker Visibility Final Rule - 23 CFR Part 634
A new FHWA regulation (Worker Visibility Final Rule - 23 CFR Part 634) that goes into effect on November
24, 2008 requires firefighters and other first responders responding to or working at an incident on federally
funded highways to wear a retro reflective safety vest that meets the Class II or III standards of the American
National Standards Institute/International Safety Equipment Association (ANSI/ISEA) 107-2004 publication.
The ANSI/ISEA 207-2006 Public Safety Vest standard has also been interpreted as meeting this requirement.
