Hydrogen Sulfide (H₂S) Reference Tag
Hydrogen Sulfide (H₂S) Reference Tag
Hydrogen sulfide (H₂S) is one of the most dangerous gases encountered in fire service and confined space work — and small changes in ppm can mean a major change in risk.
This hydrogen sulfide reference tag gives you a quick, reliable way to interpret H₂S 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 critical exposure levels, symptoms, and hazards are always within reach.
Quick reference for H₂S ppm readings and exposure thresholds
Clear guidance for increasing danger levels
Symptoms and treatment info on the reverse side
No phone or manual needed in the field
If you’re carrying an H₂S meter, this is the fastest way to understand readings under pressure.
