Hydrogen Sulfide (H2S) Awareness
Hydrogen sulfide (H2S) awareness — properties, exposure limits, detection, and response in oil & gas and wastewater work.
Length
1.7 hours
Format
Self-paced online
Renewal
Every 12 months
Modules
7
Who it's for
Oil and gas, drilling, refining, wastewater, and tank-cleaning workers who may encounter hydrogen sulfide.
Why it matters
H2S is colorless, heavier than air, and quickly deadens your sense of smell — so workers cannot rely on odor to detect it. Recognized practice (ANSI Z390.1) calls for awareness training before exposure.

FAQ
Why can't I just rely on the smell?
At low levels H2S smells like rotten eggs, but it rapidly causes olfactory fatigue — at dangerous concentrations you stop smelling it. Gas monitors, not your nose, are the control.
Is H2S training legally required?
OSHA cites it under the General Duty Clause and air-contaminant limits; ANSI Z390.1 is the consensus standard most operators require before site access.
