This course shows workers how to work safely in and around hydrogen sulfide (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 colourless, 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.

For these reasons, training in how to protect yourself is crucial in any industry where H2S might be encountered. This course provides participants with the skills and knowledge to help them identify and detect H2S, mitigate the hazards of working in an H2S environment, and respond to an incident involving an H2S release. It includes both theory and practical application exercises.


Upon successful completion of the course and examination with a minimum score of 70%, you will receive a Certificate of Completion that is valid for three years.

H2S Alive FAQ

Do you have to be clean-shaven for h2s Alive?

 It is not required as part of the program to be clean-shaven. However, you may not fit the mask you will be wearing at the course, as it conforms better to a face that has no beard. Be aware that you will need to be clean-shaven when you go to a field location and are expected to wear a respirator in an emergency situation.

How long is the h2s Alive course?

 The course ranges from  up to 8 hours.  The time depends on the size of the class, number of breaks, length of the lunch break, and how long it takes the class to write the exam.

What is the difference between h2s Alive and h2s awareness?

 H2S Alive is a franchised course by Energy Safety Canada and offered through Authorized Providers.  To be allowed entry to most oil and gas facilities, particularly in the upstream oil or gas sector, the only accepted course is H2S Alive. Workers must show their skills are competent in the class, such as donning SCBAs and conducting rescues.  Students must receive at least 70% on their exam.

H2S Awareness is a course designed to provide general awareness to workers who might have limited exposure to Hydrogen Sulphide gas but don’t enter typical petroleum sites in Alberta.

What is h2s certification?

 H2S Alive, an Energy Safety Canada trademarked product, has been adopted as a standard for the petroleum industry. It has the most recognition in Western Canada as the school to provide training on hydrogen sulphide gas. As a result, most employers have a preference for employees and visitors or contractors with this certification.

What does h2s stand for?

Hydrogen sulfide gas.

H2S is the chemical name for hydrogen sulphide gas, which is a naturally occurring toxic gas that is found in Alberta and many other areas of the world.  It can be produced as a by-product of drilling and is found in volcanic activity, and sulphur mountains as well as industries such as pulp and paper, mining, wastewater containment, and in sewers.  The H2S Alive program is a training session designed to make people aware of the dangers and properties of hydrogen sulfide gas.

How fast can h2s kill you?

H2S is called the “two second  knockdown”, as it is highly toxic to humans and other animal species.  It can cause the respiratory system to fail rapidly but can also affect the cardiovascular system and neurological system and cause pulmonary edema. Death can occur immediately above 700 ppm.  The IDLH or Immediately Dangerous to Life and Health limit of 100 ppm has been established Federally in Canada.

What does h2s smell like?

Hydrogen sulfide has a rotten egg smell.  Some common names for the gas include sewer gas, stink damp, swamp gas, sour gas, acid gas, and manure gas. It occurs naturally in crude petroleum, natural gas, and hot springs and where anaerobic decomposition occurs. Why it is considered so dangerous is that people have a problem detecting the odor over a low odor threshold.  Once they lose the smell, they think that H2S has gone away.  In fact, it may be increasing in intensity
