Sulfur Dioxide (SO₂) Reference Tag
Sulfur Dioxide (SO₂) Reference Tag
Sulfur dioxide (SO₂) is a highly irritating gas that can quickly impact breathing, visibility, and crew effectiveness — even at relatively low concentrations.
This sulfur dioxide reference tag gives you a fast, reliable way to interpret SO₂ ppm 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 exposure levels, symptoms, and response guidance are always within reach.
Quick reference for SO₂ ppm readings and exposure thresholds
Clear progression from irritation to dangerous exposure levels
Symptoms and treatment guidance on the reverse side
No phone or manual needed during response
If you’re monitoring sulfur dioxide, this is the fastest way to understand readings under pressure.
