What is fire retardant clothing made of?


Fire retardant clothing is designed to protect workers from flames and heat in potentially hazardous environments. These garments are made from special fabrics that have been treated with chemicals to resist ignition, prevent the spread of flames, and self extinguish.

The specific composition of fire retardant clothing can vary depending on the intended use and level of protection required, but the following materials are commonly used:

  1. Nomex:

    Nomex is a heat resistant fibre made from aramid polymer that is used in a wide variety of applications, including firefighting gear, racing suits, and military apparel. It has excellent resistance to flames and high temperatures, and does not melt or drip when exposed to heat.
  2. Kevlar:

    Kevlar is another type of aramid fibre that is known for its high strength and resistance to cuts, abrasion, and punctures. It is often used in combination with other materials to create fire resistant garments that can withstand extreme conditions.
  3. Carbon fibre:

    Carbon fibre is a lightweight, high strength material that is commonly used in aerospace, automotive, and sporting goods applications. It has good thermal resistance and can help protect against radiant heat and flames.
  4. Modacrylic:

    Modacrylic is a synthetic fibre that is inherently flame resistant and is often used in protective clothing for industrial workers. It is soft, lightweight, and comfortable to wear, and can provide good insulation in cold environments. Here is an example of a Modacrylic hi vis jacket.
  5. Flame resistant (FR) cotton:

    FR cotton is a type of cotton fabric that has been treated with chemicals to make it resistant to flames and heat. It is a cost effective option for industries such as oil and gas, where workers are exposed to potential fire hazards.

In addition to these materials, fire retardant clothing may also include other features such as reflective tape, moisture wicking properties, and ergonomic design elements to maximize comfort and mobility. When selecting fire retardant clothing, it is important to consider the specific hazards of the work environment and choose garments that provide the appropriate level of protection for the job at hand.
