How to Navigate the FR Clothing Marketplace

When the original version of the OSHA 1910.269 standard was published, flame-resistant (FR) clothing wasn’t even mentioned. The dangers associated with electric arcs were known, but the standard only required that an employer not allow an employee to wear clothing that, when exposed to flames or electric arcs, could increase the extent of injury sustained by the employee. This was covered under 1910.269(l)(6)(iii). The rule eliminated the use of garments constructed with synthetics such as polyester, nylon, rayon and acetate, which could melt and drip, and led to the adoption of clothing made with 100 percent cotton. The problem was that non-FR cotton – once exposed to thermal energies beyond its ignition point – will ignite and continue to burn, thus adding to an injury.

Now that the much-anticipated revisions to the 1910.269 standard have been published, they have introduced a number of new challenges to the electric utility industry and those entrusted with their employees’ safety. Specifically, page 20317 of the final rule (see states that the “new provisions for protection from electric arcs include new requirements for the employer to: Assess the workplace to identify employees exposed to hazards from flames or from electric arcs, make reasonable estimates of the incident heat energy to which the employee would be exposed, ensure that the outer layer of clothing worn by employees is flame resistant under certain conditions, and generally ensure that employees exposed to hazards from electric arcs wear protective clothing and other protective equipment with an arc rating greater than or equal to the estimated heat energy.”
