⚠ DANGER: Strong oxidizer that dramatically intensifies combustion. Oxygen-enriched atmospheres (>23.5%) cause ordinary materials to burn with extreme intensity. NEVER use oil, grease, or contaminated fittings on oxygen equipment.
GHS Hazard Pictograms
🔆 Oxidizer🔵 Compressed Gas
Hazard Statements (H-codes)
H270 – May cause or intensify fire; oxidizer
H280 – Contains gas under pressure; may explode if heated
Precautionary Statements (P-codes)
P220 – Keep away from combustibles
P244 – Keep valves and fittings free from oil/grease
P370+P376 – In case of fire: Stop leak if safe to do so
P403 – Store in well-ventilated place
First Aid Measures (Section 4)
👁Eye Contact▼
High-pressure gas contact: flush with water. Cryogenic contact: do not rub; flush with tepid water; seek medical attention.
🖐Skin Contact▼
Cryogenic contact causes frostbite. Do not rub. Warm with tepid water. Seek medical attention.
🫁Inhalation▼
Pure O2 breathing: remove from source. While O2 is not toxic short-term, high-pressure exposure can cause O2 toxicity (CNS effects) in diving scenarios.
🫦Ingestion▼
Not applicable.
Storage & Handling
🔒 Storage & Handling: Separate oxygen cylinders from fuel gas cylinders by at least 20 feet or a fire wall. Store upright, secured, away from oil and grease. Use only oxygen-compatible fittings.
PPE Requirements
Safety glasses
No oily gloves or clothing
Flame-resistant clothing in oxygen-enriched environments
