What is the primary purpose of using fire-resistant blankets during welding?

The primary purpose of using fire-resistant blankets during welding is to protect flammable materials from sparks. During the welding process, high temperatures and flying sparks can pose a significant fire hazard. Fire-resistant blankets are specifically designed to resist ignition and help contain any sparks or molten metal that may escape during welding operations. By placing these blankets over or around flammable objects and materials, the risk of fire is greatly reduced, ensuring a safer working environment for welders and others nearby.

While shielding welders from heat, providing comfort, and enhancing visibility may be important considerations in a welding environment, they are not the primary function of fire-resistant blankets. The key focus is on fire prevention and protection, making the use of these blankets a critical safety measure in welding practices.
