Welding Equipments: Pressure Reducing Equipment and Torches

Oxygen, acetylene and other compressed gases shall never be used from a cylinder without reducing the pressure through a pressure-reducing regulator bearing an Underwriter Laboratory (UL) or Factory Mutual (FM) approval.Oxygen regulators shall be used only on oxygen cylinders and fuel gas regulators on fuel gas cylinders. Oxygen regulators are provided with national standard right hand threads and fuel gas regulators with left hand threads.

Handle all pressure regulating equipment with care to avoid damage to the mechanism.

Never use oil or grease on cutting or welding equipment for any purpose.

Regulators in need of repair shall be returned to the supplier or a person authorized to do such work shall make repairs. Inspect regulating equipment and torch prior to every use. Remove unsafe equipment from service.

Always stand to the side of regulators when opening or closing valves and making adjustments.

When a regulator is not in use, the pressure adjusting screw shall be released and the cylinder valve closed. A cylinder valve shall never be opened until the pressure adjustment screw on the regulator is fully released.

When burning or welding overhead, the regulators on the cylinders shall be properly protected to prevent sparks and objects from falling on them.

Regulators shall be removed from cylinders before cylinders are moved from one location to another unless they are in a carrier specifically designed for transporting.
