Flame-resistant clothing is designed to protect wearers from exposure to flames, while arc-flash protective clothing is designed to protect wearers from electrical arc flashes that can cause severe burns.

Flame-resistant clothing is typically made from materials such as cotton or wool, which have a low propensity to burn or melt, while arc-flash protective clothing is typically made from materials such as Nomex or Kevlar, which have high resistance to electrical arcing.

Flame-resistant and arc-flash protective clothing is required in industries where there is a risk of exposure to flames or electrical arcs, such as the electrical, utility, oil and gas, and manufacturing industries.

Flame-resistant and arc-flash protective clothing should be inspected regularly for damage and cleaned according to the manufacturer's instructions, as improper care can compromise the protective properties of the garments.
