What safety equipment is essential when working with gas appliances?

When working with gas appliances, having a fire extinguisher readily available is essential due to the inherent risks associated with flammable gases. Gas appliances can potentially leak flammable gas, creating a situation where ignition can occur easily, leading to fires or explosions. A fire extinguisher provides a critical first line of defense in quickly addressing any fire that may start, allowing for immediate action to minimize damage and ensure safety for personnel in the surrounding area.

While other safety equipment, such as safety goggles, hearing protection, and respirators, may be important in specific scenarios or environments, they do not directly address the primary hazards associated with gas appliances like the risk of fire. Therefore, the presence of a fire extinguisher remains the focal point of safety when dealing with gas-related work.
