High-Pressure N2 & O2 Servicing — Why This Matters
- Aircraft N2 and O2 systems are stored at very high pressure — typically 1,800–3,000+ psi depending on the system.
- A cylinder, hose, or fitting failure under this pressure can cause serious injury or death.
- Oxygen systems also carry an additional fire/explosion hazard that nitrogen does not.

SOP & compliance notes
- Never mix N2 and O2 servicing equipment — cross-contamination is a fire/explosion risk
- Keep oil and grease away from all oxygen system components, always
