What is a necessary measure when conducting any welding operations?

When conducting any welding operations, ensuring that a fire guard is present is crucial because welding generates sparks and heat, which can easily ignite nearby flammable materials. The role of the fire guard is to monitor the environment actively, watching for any signs of fire and being prepared to act quickly should a fire start. This proactive measure helps prevent fires and protect both equipment and personnel in the vicinity.

In a welding environment, the risk of fire is significantly heightened, making it essential to have someone designated specifically for fire watch duties, especially if the operation occurs in a location with combustible materials. This safety measure is part of a broader approach to ensure a safe working environment during welding activities.
