What is the first action to take in the event of an emergency during oxyfuel cutting?

In the event of an emergency during oxyfuel cutting, shutting off all gas supplies is the most critical first action. This immediate response is essential because it helps to eliminate the source of potential hazards, such as fire or explosion, that can arise from leaking gases. Oxyfuel cutting involves the use of oxygen and a fuel gas, which can be extremely dangerous if not managed properly.

By shutting off the gas supplies, you significantly reduce the risk of a fire escalating or harmful fumes accumulating. This action must be prioritized to ensure the safety of everyone in the vicinity. Once the gases are secured, it is safer to proceed with further actions, such as calling for help or inspecting for damages, but those responses should come after the immediate danger has been addressed by cutting the gas supply first.
