Oxygen (O₂) Reference Tag
Oxygen (O₂) Reference Tag
Oxygen (O₂) levels are critical to life safety — and small changes outside the normal range can quickly lead to impaired judgment, unconsciousness, or increased fire risk.
This oxygen reference tag gives you a fast, reliable way to interpret O₂ percentage readings in the field without relying on memory.
Designed as a durable, field-ready cheat sheet, it attaches directly to your gas monitor or bunker gear so safe ranges, deficiency risks, and oxygen-enriched hazards are always within reach.
Quick reference for oxygen (O₂) percentage ranges
Clear guidance for oxygen deficiency and enrichment hazards
Immediate context for impaired judgment and life-threatening conditions
No phone or manual needed during response
If you’re using a gas monitor, this is the fastest way to understand oxygen readings under pressure.
