CGA G-4.1 Oxygen Cleaning Services
Professional hydrocarbon removal for aerospace, medical gas, and industrial oxygen systems. Compliant with Compressed Gas Association G-4.1 standards.
In pure oxygen environments, ignition energy requirements drop by up to 90%, making even trace hydrocarbons extremely dangerous.
Materials that won't burn in normal air can spontaneously combust when exposed to high-pressure oxygen and contamination.
The aerospace industry has documented numerous incidents traced directly to inadequate oxygen system cleaning.
Why Oxygen Cleaning Matters
Oxygen-enriched environments demand absolute contamination control. Any hydrocarbon residue creates catastrophic fire and explosion risk.
The Science of Oxygen Fires
In oxygen-enriched environments, materials that wouldn't normally burn become highly flammable. Hydrocarbons, oils, greases, and organic particles can spontaneously ignite when exposed to high-pressure oxygen. The ignition energy threshold drops dramatically as oxygen concentration and pressure increase—what's safe in air becomes deadly in pure oxygen. This is why CGA G-4.1 cleaning protocols exist: to eliminate every trace of combustible contamination before oxygen service.
