Welding Blankets: Fire Safety in Welding Workshops
What Is a Welding Blanket?
A welding blanket is a heat-resistant fiberglass curtain or cover designed to protect against sparks, molten metal spatter and high heat generated during welding. It shields both the operator and any nearby flammable materials.
Why It's Necessary
Welding sparks can travel several meters and ignite flammable materials — wood, oily rags, chemical storage — on contact. A welding blanket stops those sparks, making it a critical layer of workplace and fire safety, especially in enclosed workshops and job sites.
Applications
Welding blankets are used in welding and metalworking shops, factories and production facilities, shipyards, construction sites, and heavy industrial plants — to curtain off a welding station or protect nearby flammable equipment and materials.
Frequently Asked Questions
Is a welding blanket the same as a fire blanket?+
Both are made from heat-resistant fiberglass, but they serve different purposes: a fire blanket extinguishes a small fire, while a welding blanket prevents welding sparks from starting one in the first place.
What temperatures can a welding blanket withstand?+
Fiberglass welding blankets are built to withstand the brief, intense heat of welding sparks and spatter — designed for spark/splash protection, not continuous high-temperature exposure.
