OPITO Hydrogen Sulphide (H2S) Training Program - Hazards and Properties of H2S and Appropriate Emergency Response

opito h2s

H2S (Hydrogen Sulphide) is a gas that can be created by natural biological processes or by human activity and poses a serious threat to people or assets because of its extremely toxic and corrosive properties. It is important, therefore, for oil and gas personnel to be competent in emergency response practices necessary for them to stay and work in an environment with potential for exposure to H2S gas.

The OPITO Basic H2S Training covers the emergency response competency requirements and provides details of training required for personnel working in potential H2S environments. This training covers the characteristics of hydrogen sulphide gas and the potential physiological effects of exposure as well as the use of H2S detection equipment and escape breathing apparatus.


The training ensures that the delegate gains the required knowledge and understanding of the particular hazards and properties of H2S, and appropriate emergency response actions to take should a H2S related incident arise.

The H2S training program is for personnel that are or could be, working in an environment that could become contaminated by H2S gas.

  • Duration: 4 hours

Basic H2S Training




Basic H2S Training (Theory)

  • Hydrogen sulphide - how it is formed and where it is found
  • Other names used to describe H2S
  • Properties and characteristics of H2S
  • Parts per million (ppm) as a measurement parameter
  • Occupational exposure limits to H2S
  • Factors affecting individual susceptibility to H2S
  • Types of detector equipment
  • Types of respiratory equipment
  • Pre-use checks of personal detection devices and EBA

Basic H2S Training (Practical)

  • Operating personal H2S detection equipment (including checks)
  • Responding to an alarm
  • Donning & operating (including checks) an escape breathing apparatus (EBA) with a mask within 30 seconds
  • Donning & operating (including checks) an EBA with a hood within 30 seconds
  • Connecting to a pressurized cascade breathing system with an activated EBA which has been donned correctly
  • Disconnecting from a pressurized cascade breathing system with an activated EBA which has been donned correctly
