745 Welding, Cutting, and Brazing Safety

Regulator and Hose Safety

• Use only correctly matched regulators and hoses for each gas type. Never interchange those intended for oxygen with those for acetylene.
• Do not attempt to force unmatching or crossed threads on valve outlets, hose couplings, or torch valve inlets.
• Ensure that oxygen regulator outlets, hose couplings, and torch valve inlets have right-handed threads, while acetylene fittings have left-handed threads.
• Always inspect hoses for leaks or damage before use.
• Keep hoses away from sharp objects, flames, and hot metal to prevent burns or punctures.

Torch & Cutting Equipment Safety

Proper handling of torch and cutting equipment is essential for maintaining a safe work environment and preventing accidents.

Incorrect use of gas torches can lead to fire hazards, explosions, and exposure to harmful gases. The following guidelines outline key precautions for safely operating torch and cutting equipment.

• Use the correct tip or nozzle and set the correct gas pressure for the job. This information is available in equipment manuals or tables.
• When lighting the torch, open the acetylene valve first and ignite the gas before opening the oxygen valve.
• While operating the torch, be careful to adjust it properly to prevent backfire or flashback.
• When turning off the torch, close the acetylene valve first, then close the oxygen valve.
• Do not allow unburned acetylene to escape and accumulate in confined spaces, as it is highly explosive.
• Keep the torch and work area free of excess gas buildup to prevent fire hazards.
• Ensure that the work area allows easy access to cylinder valves for quick shutoff if needed.
