Protective clothing for welders: Ensuring safety in high-risk environments

Welding, grinding and working with hot materials pose significant risks to welders. WorkSafe has investigated numerous incidents where welders’ clothing caught fire during welding, grinding or contact with hot welded plates which resulted in serious burns requiring medical attention.

Wearing appropriate protective clothing when undertaking welding works is essential in safeguarding welders.

Untreated cotton drill clothing, including highvisibility garments, often claim compliance with standards. However, they are not inherently flame-resistant.

While synthetic materials like nylon and polyester can be difficult to ignite, once ignited, can melt and drip. The melted material can cause serious burns when it drips onto exposed skin.

Undergarments made from loose-weave fabrics are highly flammable and should never be exposed during thermal cutting, grinding, or welding. Ignited undergarments can set the outer garment ablaze, exacerbating the risk.

Flame-resistant cotton drill clothing is highly recommended as protective clothing for welders. While it may cost a bit more, the safety it provides outweighs the investment. Look for clothing labels ISO 11611, ISO 11612, ISO 14116, ASTM F1959 and AS/NZS 4502.2 as they conform with flame-resistant standards.

Guidelines for protective clothing

• Full coverage: ensure clothing protects all parts of the body from hot particles or objects.
• Preferred fabrics: opt for leather, wool, or flame-resistant cotton drill.
• Avoid cuffs and open pockets: garments should be free of cuffs or open pockets that could trap molten metal and cause local burns or fires.
• Proper fit: snug wrists but loose-fitting overall, especially in hot conditions.
• Footwear coverage: clothing should cover the tops of footwear.
• Maintenance: regularly launder clothing as per manufacturer’s guidance and check for holes.

By following the guidelines and investing in flame-resistant clothing, welders can significantly reduce the risk of burns and injuries. See the Welding processes: Code of practice for more information.
