FR Pants FAQ

What rating do FR pants need?

The same as your shirt: NFPA 2112 for flash fire, and an arc rating that meets your PPE category for electrical work. See our FR rating guide and how to read an FR label.

Can I hem FR pants?

Ask first. Hemming with regular thread leaves a non-FR seam. We can find the inseam you need so you don't have to alter them.

How do I wash FR jeans?

Follow the care label and our FR washing guide. Skip chlorine bleach, fabric softener and starch. Retire jeans with holes, worn-through knees or oil that won't wash out; see when to replace FR clothing.

Can my company buy FR pants through a program?

Yes, through our company programs, with a set allowance per worker.
