Basic H2S Training

This four-hour Basic H2S Training Course is Safe Zone-approved and aimed at all personnel who risk exposure to hydrogen sulfide contamination at work. The fire training covers the detection and measurement of the flammable gas, plus the correct emergency response to an H2S leak. Basic H2S Training certification should be re-validated every three years.
The aims and objectives of the Basic H2S Training are to ensure 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.
H2S is one of the most deadly occupational hazards affecting operations in the oil and gas industries. 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
