Best FR Coveralls


Flame Resistant “FR” coveralls are designed to protect your body against flames. FR material will self-extinguish after the heat source is removed. You may be familiar with fire-retardant clothing and wonder if it’s the same as FR material. They are different! Fire retardant clothing is made with non-flammable fabrics while FR textiles are chemically treated to be self-extinguishing. 

FR coveralls are worn in many industries including manufacturing, oil and gas, aerospace, agriculture, and electrical. Protection against flames and flash arcs are required in many of these industries.

What are coveralls?

Coveralls are worn over clothing to protect skin and clothing. They are the gold standard for personal protective equipment (PPE) to protect against a number hazards, including harsh weather, chemicals, fire, and dirt. They cover your body from your neck to ankles plus arms and shoulders. The arm and shoulder protection is the main difference between coveralls and overalls. Some disposable coveralls come with a protective hood that can be used to cover your head as well.


Coveralls are made in different styles, colors, functionality, and material. FRs are designed to reduce the risk of burns and are made of either 100% cotton or a mixture of cotton and nylon twill. Nylon twill is a strong material that’s designed to be flame resistant. It’s important to know that coveralls may be FR but not arc resistant. 


FR coveralls offer protection against flames and flash arcs. It’s important to buy certified tested coveralls to be sure you are protected. The manufacture of FR material is governed by two organizations: the National Fire Protection Association (NFPA) and the Institute for Electrical and Electronics Engineers (IEEE). 

Flash arcs are a common hazard in many environments. NFPA 70E standard has four protection categories ranging from least to most protective. It’s important to know the arc level you may be exposed to before wearing coveralls. The guidance is to at least meet the minimum arc rating.

NFPA 2112 standard covers flame resistant materials. The organization mandates certain tests to be performed on material before manufacturing. The fabric is tested to determine if a maximum of 50% total body burn will occur when ignited for 3 seconds. In addition, the material cannot melt, drip, or have after-flame burning.


Manufacturers make a variety of styles of FRs clothing. They are not created equal and will depend on your working environment and environmental conditions.

  • Standard FRs are coveralls that are flame resistant by definition. They are made with either cotton or nylon twill for protection. They are ideal for hot weather, light rain, and cool climates. 
  • Insulated coveralls are designed to be worn in colder climates. They are insulated with materials to battle harsh winters while affording protection against flames. 
  • Overalls can be made of flame retardant fabric although by design, overalls do not protect shoulders and arms.  A FR jacket must be worn to cover your torso for full body protection. Some people find this more comfortable while others prefer wearing only one garment, a FR coverall.

Coveralls keep you safe, comfortable, and are designed to last years of wear. It’s important to maintain proper care of them as tears, abrasions, and other damage will reduce their protective capabilities.
