Flammable Materials You Should Never Wear while Welding

Part of the welding workforce must think about the functionality and practicality of their work attire while others are more focused on how they appear when getting ready for work. For some, this entails dressing in flame-resistant (FR) attire while working.  You might be shocked to learn which fabrics are among the most combustible and how frequently clothes producers still use them.


It’s critical to remember that flammability varies depending on a variety of elements, including the fabric’s construction, fiber content, and chemical treatments.  However, if fire threats are a regular part of your workday, you should avoid using these extremely combustible products that are prohibited by the United States Occupational Safety and Health Administration (OSHA).


Flammable Materials you should never wear while welding

The following materials are forbidden in work clothing, whether they are used alone or in blends, according to the Occupational Safety and Health Standard 1910.269 of the United States Occupational Safety and Health Administration (OSHA), “unless the employer demonstrates that the fabric has been treated to withstand the conditions that the employee may encounter or that the employee wears the clothing in such a manner as to eliminate the hazard involved.”


When melted onto another surface, acetate burns quickly and is difficult to remove. This is crucial for any non-FR apparel that is worn underneath FR clothes. Even while these undergarments may not come in direct contact with heat or flames, they could nonetheless be subjected to enough thermal energy to melt.


Because nylon is a synthetic fabric that shrinks when burned, it is not good to wear it while welding. It easily catches fire with just one spark, sticks to the skin, and makes burns worse. Nylon fibers continue to stick to the flesh even after the fire has been put out, doing further damage.

Polyester fibers in synthetic fabric are not flammable. Polyester fabric, though, is flame-resistant. This fabric will melt at a high temperature. Never wear this synthetic material since it will ignite and burn rapidly.



Cotton is equally as highly flammable as rayon, acetate, and triacetate. Acetate and triacetate may also melt and result in severe burns. The flammability of nylon, polyester, acrylic, and olefin is low. However, the melting of the fiber after ignition might result in severe burns.



Because the polymer is easily combustible due to its chemical makeup, flame retardancy becomes a crucial need. Polypropylene dissolves in aromatic hydrocarbons like benzene and toluene at temperatures above 100 °C.
