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.
