FAQ - Fire Resistant Work Clothing

What is the best FR rated clothing?

IFR, Action West and Big Bill are three Canadian companies that have specialized in FR and PPE clothing for decades, and their FR clothing is carried at Wei’s.

Increased demand for PPE and safety clothing has attracted well-known work wear brands like Carhartt, Ariat and Wrangler who now offer several styles of FR clothing, from bib overalls to hoodies, pants and plain or patterned shirts. Wei’s carries a big selection of FR clothing.

Safety regulations have improved over the years, resulting in more requirements for specific types of FR clothing, which must meet inspection and testing standards.

FR Treatments Vs. Inherently FR Materials

Cotton is a good insulator against heat and a poor conductor of electricity, and often used in FR clothing – but it will catch fire when exposed to direct flame.

Some FR manufacturers might use treated cotton clothing instead of inherently fire-resistant fibres or fabrics. The problem with treated clothing is the chemical treatment will wear off after several washes. Your protection lessens or disappears, and you are not fully protected as the jobsite requires.

In Canada, this deterioration of FR protection must be stated on the label - for example, 'replace after 20 washes'.

Does FR Treatment Wash Away from Treated Cotton?

Yes.  The label will give you an idea of how many washes your treated FR clothing can withstand before you need to replace it to ensure your safety code compliance.

What Are Inherently Flame-Resistant Materials?

For better protection, buy better FR clothing using materials that are inherently fire resistant. FR materials are such as Nomex or Kevlar are designed at the molecular level to inhibit electricity, arc flashes and heat.

These materials are inherently fire-resistant and resist catching fire when exposed to extreme heat and combustion. They are available in fibres or fabrics to clothing manufacturers who use them to make the industry-standard flame resistant clothes

Why Not Use Polyester?

Synthetic fibres such as nylon, polyester, acetate or rayon, when heated, could melt onto your skin, therefore FR clothing is never made with 100% of these synthetic materials, but blends, for example with a higher percentage of cotton and a lower percentage of polyester, are common.

Cotton may be blended with polyester as well as a specialized FR material to provide durability as well as protection.
