OPITO Basic H2S Training
Learners attending this training and assessment programme will be given a series of explanations and demonstrations which will identify what they are expected to know and do. This will be followed by practical exercises which will allow learners to demonstrate their knowledge and understanding and emergency response skills.
Learners will be assessed against the learning outcomes using direct observation, and oral and written questions as appropriate.
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 standard 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 course consists of the following modules:
- 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
- Operating personal H2S detection equipment (including checks)
- Responding to an alarm
- Donning & operating (including checks) an escape breathing apparatus (EBA) with a mask
- Donning & operating (including checks) an EBA with a hood within 30 seconds
- Connecting to a pressurised cascade breathing system with an activated EBA.
- Disconnecting from a pressurised cascade breathing system with an activated EBA.
