H2S Training

Definition - What does H2S Training mean?

H2S (Hydrogen Sulfide) training is a course designed for employees who are engaged in operations where there is a potential risk of H2S being present. H2S trained individuals might include employees of an oil and gas company (well drilling, servicing, work over, down hole maintenance, plug and abandonment procedures etc.) or individuals involved in the storage and transports of such substances that release H2S. It is a highly toxic gas that can kill or seriously harm human health even at low concentrations (e.g.10 ppm). It is also flammable, thus it is a fire hazard.

Safeopedia explains H2S Training

H2S training is mandatory for employees engaged in oil and gas field, rig, storage and transports. Offshore Petroleum Industry Training Organization (OPITO) has approved a basic H2S training standard that covers the emergency response competency requirements and provides details of training required for personnel working in possible H2S environments. The participants of H2S training learn the following:

  • How H2S is formed, where found, characteristics and hazards associated with H2S

  • Parts per million (ppm) as a measurement parameter

  • Exposure limits of H2S and individual vulnerability

  • Types of detectors, respiratory equipment and escape breathing apparatus (EBA) and their practical use including alarm, donning and operating

  • Connecting to a pressurized cascade breathing system with an activated EBA which has to be worn correctly (correct facemask fit)

  • Recognition of and proper response to, H2S warnings at the workplace

  • Symptoms of H2S exposure, rescue techniques and first-aid procedures to be used in a H2S exposure

  • Confined space and enclosed facility entry procedures

  • Emergency response procedures, corrective actions and shutdown procedures

  • Effects of H2S on the components of the handling system
