Swift Current

This course shows workers how to work safely in and around hydrogen sulphide (H2S) environments.

H2S is a naturally occurring gas. It is often referred to as sour gas, acid gas, stink damp or sulphurated hydrogen. H2S is colorless, heavier than air in its pure state, and extremely toxic. It can also deaden your sense of smell. In low concentrations, it has a rotten egg smell and causes eye and throat irritation. At higher concentrations, it can cause death.
