What does FR mean on Clothing?

FR means Flame resistant clothing. A cloth piece that burns very slowly or extinguishes by itself and which doesn’t promote the fire is the FR cloth.

These clothes tend to push the oxygen away from them and slower down burning speed up to a great extent. Let’s discuss the FR clothing and walk through all the basic about it.

1) Who are advised to wear Flame resistant clothes?

The employees of a unit where the environment is more prone to heat, fire or electrical injuries are always advised to wear FR clothing sets. The electri-cians, electricity utility workers, pharmaceutical and chemical workers, refin-eries’ workers, workers in food processing units, workers of paper and pulp industries, etc should always take precautions and wear FR clothes. You can find various outstanding FR clothing sets on the official website of the FR Outlet.

2) Is there a difference between primary and secondary protection?

Both of these terms, “primary protection” and “secondary protection”, are quite frequent when we talk about FR clothing. A brief breakdown of these terms is given below.

• Primary protection:

The primary protection gear is specifically designed for the workers who are constantly exposed to flames, radiant heat and potential molten substance splash. For example, a firefighter’s gear. When a firefighter or a Fire Watch Guard is going to move into the fire for his duty, he will definitely need the additional measures offered by primary protection gear.

• Secondary protection:

The secondary protection gear is specially designed for workers who may en-counter intermittent hazards. More precisely, the user of secondary gear is not as much in danger as the wearer of the primary gear.

3) What is generally preferred to wear under the FR clothing gear?

The clothing pieces you choose to wear under the flame-resistant gear play a major role in your safety and the effectiveness of your FR clothing. There are various perks of taking this caution. The very first is that you are adding up a second layer FR protection, therefore, if by chance your upper layer of FR set gets damaged or burned, you will still be having a second protection layer to protect you. Plus, there is also a layer of air insulation to provide some more protection.

The second reason is that it might happen that if you wear a flammable cloth material underneath, it might melt due to the environment you are working in. Although your outer gear provides protection, you might end up damaging the inner layer while the upper layer is still good due to the extreme enough con-ditions and temperatures in the environment. The bottom layer may ignite and can cause severe injuries.

4) What is the difference between Flame-resistant, Fire-resistant, and Fire-retardant?

You might believe that all these terms are synonymous. The first two terms are mostly interchangeable but the third one isn’t.

• Flame-resistant: These clothes are made up of inherently non-flammable fabrics and materials. These clothing protection gears have a chemical structure which is resistant to fire. These clothes might catch fire but either it will be extinguished very quickly or it will burn very much slower. The tar-get of these clothes is to prevent the further spread of fire; to prevent the further spread of fire.

• Fire-resistant: This thing is synonymous to the flame resistant. Do not get confused when you see both of them as both of these words are inter-changeable.

• Fire-retardant: These fabrics are those which have gone through a chemi-cal treatment to get the same properties as the flame-resistant clothes have. Any kind of fabric can be converted into fire-retardant fabric by treating it under certain chemicals.


Hope, the above-stated facts have provided you with a comprehensive idea and clear concept of fire-resistant clothing.
