FR Clothing Guide: Safety and Regulations

What is FR Clothing?

FR garments are made from special fabrics and coatings designed to withstand high temperatures and resist ignition from combustible materials. Common materials used include:

  • Treated cotton
  • Treated cotton/high tenacity nylon blends
  • Kevlar
  • Modacrylic
  • Nomex

FR clothing is crucial for worker safety in industries with high risks of injury or death from fires or thermal transfer. In these environments, FR garments are often not just recommended, but also legally required.

FR Clothing Guide

Key Regulations

Occupational Health and Safety Code

Requires employers to ensure workers wear FR clothing and other essential PPE to protect against hazards like flash fires and arc flashes.

Example: Taken from Alberta OHS Laws regarding use of flame resistant clothing:

232(1) If a worker may be exposed to a flash fire or electrical equipment flashover, an employer must ensure that the worker wears personal protective equipment that includes flame resistant outerwear and uses other personal protective equipment appropriate to the hazard.

232(2) A worker must ensure that clothing worn beneath flame resistant outerwear and against the skin is made of flame resistant fabrics or natural fibres that will not melt when exposed to heat.

CGSB 155.20

A Canadian General Standards Board standard that mandates FR clothing pass specific tests and meet minimum safety requirements against hydrocarbon flash fires, steam, and extremely hot fluids.

Provincial and Territorial Laws

Some provinces and territories have their own regulations governing FR clothing use for protection against flash fires, molten metal, welding, and other thermal hazards.

Industries Where FR Clothing is Essential

Industries where FR clothing is essential due to burning hazards from electrical arc flashes, welding, molten metal, and flash fires include:

  • Electric Utilities and Power Generation: Workers face risks from electric arc flashes, which can reach over 35,000°F and cause severe burns.
  • Oil and Gas: Workers are exposed to flammable substances like hydrogen sulfide, petrochemicals, and chemical vapors.
  • Metalworking: Workers in environments like smelting plants are exposed to electric arcs, molten metal, and high temperatures that could ignite non-FR clothing.
  • Construction: Workers use heavy machinery and flammable materials, making FR garments vital protection against accidental fires, arc flashes, or sparks.
  • Food Processing: Heavy machinery and equipment used in cooking and canning expose workers to high heat and pressure.
  • Papermaking: This industry involves fire risks due to flammable materials, combustible dust, and chemicals.

Important Note:

This list is not complete. If you’re unsure about the type of PPE that you require, consulting a safety professional can help determine the necessary PPE. Always practice due diligence and refer to standards and regulations in the jurisdiction that you are working in to ensure your PPE list is comprehensive.
