Lotions, Oils and Sprays – Oh My!

Updated April 8, 2022

With summer weather comes the need to protect workers from seasonal hazards like sun exposure and disease-carrying biting insects. But when arc flash or flash fire is a risk, it’s important to think twice before reaching for the products you may use off-the-clock; unfortunately, some are flammable, presenting a burn hazard in your work environment. For example, insect repellents containing DEET are highly flammable and should never be used with arc-rated and flame resistant (AR / FR) clothing. So what solutions are safe to use with AR / FR clothing, and how can you be sure?

  • Start by looking at a product’s Safety Data Sheet (SDS).
  • Beware: many sprays like insect repellents use a “carrier” – the substance that delivers the active ingredients in the repellents to your skin – that is flammable in its wet and/or dry state, even if the SDS states the active ingredients are not flammable.
  • The only way to know for sure is to test the product in hazard conditions.

Scott Margolin, Vice President of Technical, explains:
