31) MEDICAL GASES

Cylinder Storage and Handling

Secure Storage:

  • All cylinders (portable and onboard spares) must be secured using approved brackets or straps.

  • Portable cylinders not in use must be secured in designated storage areas in the ambulance.

 

Valve Safety:

  • Always keep valve protection caps on spare cylinders when not in use.

  • Never oil, grease, or lubricate valves or regulators. This can cause combustion with oxygen.

  •  

Handling:

  • Never drag, roll, or drop a cylinder.

  • Use caution when lifting and moving; use a cart for heavy cylinders.

 

Use and Operation

Check Before Use:

  • Inspect tanks for damage, proper labeling, and fill level.

  • Ensure regulators and flowmeters are in good condition.

  • Never use a cylinder with a damaged valve or no label.

 

Proper Connections:

  • Use only oxygen-compatible equipment for oxygen tanks.

  • Ensure regulators are tightly connected and not cross-threaded.

 

Replacement Guidelines:

  • Do not allow onboard oxygen to fall below 500 psi unless in active use.

  • Replace low or empty tanks before placing the unit back in service.

  • Tag empty or partially full tanks using the provided tags.

 

Safety Precautions

Fire Hazard:

  • Oxygen-enriched environments are a serious fire risk.

  • Keep oxygen and medical air systems away from open flames, heat sources, or smoking.

 

Emergency Procedures

Leaks or Malfunctions:

  • Shut off the cylinder immediately.

  • Ventilate the area and remove ignition sources.

  • Notify a supervisor and tag the equipment as “Out of Service.”

 

Fire:

  • Activate emergency response protocols.

  • If safe, turn off the gas supply and evacuate the vehicle.

  • Use a fire extinguisher only if trained and it is safe to do so.

 

Final Reminders

  • Always treat oxygen as a hazardous material.

  • Never bypass safety checks or attempt makeshift repairs.

  • When in doubt—shut it down, step away, and call for help.
