Hydrogen Sulfide (H2S) Safety Specialist Train the Trainer (CH2ST) 

Course Introduction:

Hydrogen Sulfide (H2S) is known as an insidious killer and goes by a number of unsavory names: sour gas, meadow gas, stink damp, Devil's Breath, and sulfureated hydrogen. It is a colorless gas that can be routinely found around decaying organic material and in some oil and gas operations. It smells like rotten eggs at extremely low concentrations, but it quickly, though temporarily, kills the sense of smell at higher concentrations. (This property gives a false sense of security to the unsuspecting.)

H2S is a highly-hazardous gas which rapidly renders its unfortunate victims unconscious, paralyzes the respiratory system, and then causes death in a matter of just a few minutes.

However you can work safely in H2S environments if you are properly trained, utilize appropriate engineering precautions, and are equipped with the proper personal protective equipment.

Course Description

It is essential that employees who work in oil & gas petroleum and natural gas industries, utilities, research and development area, laboratories, transportation, paper/pulp/food processing, chemical manufacturing, tanning industries, waste disposal and other industries where the hazard of Hydrogen Sulfide Gas can be present.
