In oil, gas, petrochemical and electrical work, the right coverall can be the difference between a minor incident and a serious burn. An FRC coverall (flame-resistant clothing coverall) is designed to resist ignition, stop burning when the heat source is removed and give the wearer precious seconds to escape a flash fire or arc flash.
This guide explains what makes a coverall flame-resistant, the main fabric types, the standards your client may ask for and how to order FRC coveralls for a team. It is written by Blaze Uniforms in Dammam, where we supply Nomex fire resistant clothing and industrial uniforms.
What is an FRC coverall?
FRC stands for flame-resistant clothing. A normal cotton or poly-cotton coverall can catch fire and keep burning, and synthetic fabrics can melt onto the skin. An FRC coverall is made from fabric that will not continue to burn on its own and does not melt or drip.
FRC does not make a worker fireproof. It reduces the severity of burns and gives time to escape. That is why many sites in Saudi Arabia’s energy and industrial sectors make FR clothing mandatory in hazardous areas.
Inherent vs treated FR fabrics
Inherently flame-resistant fabrics
Fibres such as meta-aramid (best known by the brand name Nomex) are flame-resistant by their chemical nature. The protection cannot wash out and lasts for the life of the garment. Inherent fabrics are usually lighter for the protection they give, which helps in hot weather, but they cost more.
Treated FR cotton
FR-treated cotton is ordinary cotton or cotton blend that has been chemically treated to resist flame. It is comfortable and more affordable. The protection lasts for the stated life of the garment when washed correctly, but the wrong washing products can reduce it.
Both types are widely used. The right choice depends on the hazard, the client’s requirements, comfort in heat and budget.
Standards and ratings to understand
Your client or safety team may ask for coveralls that meet specific standards. The most common are:
- NFPA 2112 for protection against flash fire
- NFPA 70E and arc ratings (ATPV, in cal/cm²) for electrical arc flash risk
- EN ISO 11612 for protection against heat and flame
- EN ISO 11611 for welding and similar processes
- IEC 61482-2 for electric arc protection
Always ask your supplier for the fabric certificates, and match them to your site’s written PPE requirements. Major operators and their contractors often publish their own PPE rules, so check those before you order.
Colour and reflective tape
Red, navy and royal blue are common FR coverall colours, and many operators use colour to tell employees, contractors and visitors apart. If you add reflective tape, it must also be flame-resistant. Ordinary reflective tape can melt or burn and defeat the purpose of the coverall.
Comfort in Saudi heat
FR coveralls are worn for long hours in high temperatures. To keep workers comfortable:
- Choose the lightest fabric weight that meets the required protection level
- Consider ventilation features that do not compromise protection
- Provide enough sets for daily changes
- Remind workers not to wear synthetic clothing underneath, as it can melt
Branding FR coveralls
Logos and name tags on FR garments should be applied with FR-compatible thread and materials. Ask your supplier to confirm that the embroidery or patches used will not compromise the coverall’s rating.
Frequently asked questions
What does FRC stand for?
FRC stands for flame-resistant clothing, also called fire-resistant or FR clothing.
Is Nomex the same as FR cotton?
No. Nomex is an inherently flame-resistant aramid fibre, while FR cotton is cotton treated to resist flame. Both can provide certified protection.
Can I add normal reflective tape to an FR coverall?
No. Use FR-rated reflective tape only, because standard tape can melt or burn.
How do I know which standard my site needs?
Check your company or client’s written PPE requirements and your site risk assessment, then ask the supplier for matching fabric certificates.
