Flame-resistant (FR) clothing is a life-saving piece of PPE for workers exposed to open flames, sparks, molten metal, or other fire hazards. Used in industries like oil and gas, welding, electrical work, and manufacturing, FR clothing is designed to self-extinguish when exposed to fire, prevent burns, and provide workers with valuable time to escape dangerous situations. However, FR clothing only works effectively if it is used correctly. This guide outlines the key steps for proper use of FR clothing to ensure maximum safety.
First, select the right type of FR clothing for the specific hazard. FR clothing is rated based on its ability to withstand heat and flame, and different work environments require different levels of protection. Before using FR clothing, consult the safety data sheet (SDS) for the materials being handled and the manufacturer's guidelines to ensure the clothing meets the required standards. For example, welding workers may need FR clothing with a higher heat resistance rating than workers in general manufacturing. Additionally, ensure the clothing is the correct size-too loose, and it may catch on equipment or allow flames to reach the skin; too tight, and it may restrict movement and reduce comfort.
Proper donning of FR clothing is essential. Before putting on FR clothing, remove any loose or flammable accessories, such as jewelry, scarves, or synthetic undergarments. Synthetic materials (like polyester or nylon) can melt when exposed to fire, causing severe burns, so workers should wear cotton or other natural fiber undergarments under FR clothing. When putting on FR jackets or pants, ensure that all closures (zippers, buttons, Velcro) are fastened securely to prevent gaps that could allow flames to reach the skin. For welding workers, additional protection such as FR gloves, hoods, and face shields should be worn to cover exposed areas.
During use, avoid damaging the FR clothing. FR clothing can lose its flame-resistant properties if it is torn, burned, or contaminated with flammable substances like oil or grease. Workers should avoid dragging the clothing on rough surfaces, which can cause tears, and avoid contact with sharp objects that could puncture the fabric. If the clothing becomes contaminated with flammable materials, it should be cleaned immediately according to the manufacturer's instructions-contaminated FR clothing is less effective and may even catch fire more easily.
Never alter FR clothing. Cutting, sewing, or adding patches to FR clothing can damage the flame-resistant material and reduce its effectiveness. Even small modifications can create weak points that allow flames to penetrate. If the clothing is damaged (e.g., torn, burned), it should be replaced immediately-do not attempt to repair it. Additionally, FR clothing should not be shared between workers, as this can spread contaminants and reduce the clothing's lifespan.
After use, FR clothing should be inspected and cleaned properly. Check for any signs of damage, such as tears, burns, or fading, and replace the clothing if necessary. Clean FR clothing according to the manufacturer's guidelines-most FR clothing can be machine washed with mild detergent, but avoid using bleach or fabric softeners, which can damage the flame-resistant properties. Air dry the clothing or tumble dry on low heat, and store it in a clean, dry place away from flammable materials.
