HIGH-PRESSURE GAS CYLINDER SAFETY

Safety Guidelines for High-Pressure Gas Cylinders

SAFETY GUIDELINES FOR HIGH-PRESSURE GAS CYLINDERS

High-pressure gas cylinders include: compressed gas cylinders, dissolved gas cylinders, and liquefied gas cylinders. The contents may be in gas, liquid, liquid-vapor mixture, powder, or foam form – discharged by internal pressure.

I. Hazards & Risk Factors

  • Physical explosion hazard: caused by impacts, heating, or high temperatures.
  • Chemical explosion hazard: caused by static electricity, friction, or exposure to open flames.
  • Injury hazard: caused by falling, tipping, impacts, or high-pressure gas discharge due to improper operation.

II. General Safety Measures

  • Cylinder Placement: Keep cylinders upright or at a 45° angle with valves facing up. Securely strap upright cylinders.
  • No Operation with Oil/Grease: Never open oxygen valves if hands, clothes, or tools are contaminated with oil or grease.
  • Use Proper Tools: Only use specialized tools to open valves. Never use hammers, chisels, or extension bars.
  • Open Valves Correctly: Open slowly, turning no more than ¼ turn at a time.
  • Check for Leaks: Use soapy water or foaming solution only. Never test with open flames.
  • Storage Classification: Do not mix full and empty cylinders or store different gas types together.
  • No Direct Transfer: Always use a pressure regulator when transferring gas between cylinders.
  • Maintain Residual Pressure: Never completely empty a cylinder; leave residual pressure as required by technical standards.
