Torch Hose Safety

The welding torch hose, because it is flexible and softer than other equipment is one of the most vulnerable parts of a welding operation. A clean hose, free of debris and in good repair is critical to safe welding.

  1. Pressure

    • The U.S. Occupational Safety and Health Administration (OSHA) requires that hoses have a minimum bursting pressure of 1,000 pounds per square inch gauge (psig) (6.8 mega Pascals (MPa)). Hoses must also be connected to a check valve, pressure regulator, hydraulic seal or some combination thereof and fastened in a such a way that they will withstand, without leaking twice the pressure they normally work under.

    Wear

    • OSHA also requires that hoses with leaks, worn patches, burns or other defects be replaced. Avoiding hanging hoses up with the torch still attached extends the life of the hose by reducing wear.

    Oil

    • Another OSHA requirement is that hoses be kept clean and free of greasy or oily substances. An oily hose can be a fire hazard. OSHA requirements also state that cylinders, valves and couplings be free of oil and grease.
