Part IV: General Rules
High Pressure Cylinder Storage and Use
OSHA citation 1910.101-120, 1910.166-171
- All cylinders must be stored in an upright position or in accordance with manufacturer’s instructions and Department of Transportation (DOT) standards, and secured to prevent tipping. Valves are to be closed and safety caps are to be in place.
- Welding hoses are to be neatly rolled up and put away to avoid a tripping hazard. Before you disconnect a hose, make sure the valve is closed and the system is depressurized. Never oil the valves on cylinders, as this can cause an explosion.
- Do not lift cylinders by the cap. For short distance moving, a cylinder may be rolled on its bottom edge, but never dragged.
- Always check a cylinder’s markings to be sure it contains the correct type of material for the job. Know how and when a substance should be used.
- Do not tamper with any safety devices; report all defects to your supervisor.
- When checking cylinder gauges, stand off to one side to lessen your risk that an exploding object might hit you.
- All cylinders must have an up-to-date hydrostatic test in accordance with DOT regulations.
- Leaking cylinders should be immediately reported to a supervisor or the Operations Center (5-8728) for proper removal.
