Cylinder Safety Tips

Handling & Storage Tips

  • Always use gloves when handling cylinders
  • Never handle cylinders without caps
  • Do not use magnets, ropes or slings to suspend cylinders

  • Never mistreat cylinders i.e. drop, roll lying down on the ground etc.
  • Never assume a vessel is empty – check
  • Ensure that valves are closed and cap in place when moving any cylinder
  • Use a trolley to move cylinders, where applicable
  • Never force a valve open by knocking or heating or tighten connections while the cylinder is under pressure
  • Never store cylinders isolated (individually) unless fastened to a sturdy structure
  • Never store cylinders in a row – always nest in a three point contact position

Properly Nested Cylinders
