You must continue wearing your shock and arc flash PPE – can’t shed PPE just because it’s hot outside! Clothing ignition kills about 50% of the time.
Keep these tips in mind:
Buying from several different manufacturers? The company that makes the most comfortable pant may not make the most comfortable shirt. Especially when shopping for t-shirts, keep in mind there are arc rated moisture-wicking shirts that are amazing compared to cotton. Wear trial summer clothing in the summer and winter clothing in the winter.
Don’t spray DEET products on your AR PPE. DEET should be used to protect your skin.
You can use permethrin to spray on your PPE, but follow the instructions.
CAUTION: Don’t spray both on your skin together, and don’t spray DEET on permethrin-impregnated and treated clothing. The result can be toxic.
See the e-Hazard Blog on ArcWear Testing of DEET and Permethrin sprays on AR garments.
See this information from Indiana University on DEET and Permethrin.
