Provision of H2S Management Programme


Our client, a service company in the oil and gas industry in Libya, had contracted a third party to carry out a Health Risk Assessment. From the assessment, it was identified that there is a need to set up H2S Management Programme.

The client requested our support to set up and implement the H2S Management Programme. Air monitoring data was provided to the client by its own client.


Hydrogen Sulfide (H2S) is one of the most dangerous and hazardous gas found in the oil and gas industry. Exposure to H2S can lead to injuries and deaths. Moreover, it harms product value and creates environmental damages.


We developed the H2S Management Programme and worked with the client’s HSE Manager to implement the following:

  • Training was provided to the workers covering H2S awareness, PPE, use of personal monitoring devices, breathing apparatus, and emergency procedures.
  • A programme of personal H2S monitoring devices was rolled out to the workers at risk. Training was provided to personnel on the use of the monitors. A calibration programme was put in place.
  • A review was carried out of staff using Breathing Apparatus. Air-purifying full-face respirators with specific cartridges for H2S were implemented for areas with exposures below 100 ppm. For areas with exposures at or above 100 ppm, a full-face pressure demand self-contained breathing apparatus (SCBA) with a minimum service life of thirty minutes was implemented. Our review included face fit testing. Training was provided to the relevant personnel.
  • We reviewed the fitness to work programmes currently in place, to ensure fitness criteria for persons using Breathing Apparatus or working in H2S exposure areas.
  • We formed part of the team tasked with evaluating LEV upgrades.
  • We reviewed the emergency response plan for H2S exposure.
  • We set up procedures for management of H2S, including KPIs and methods for tracking performance and improvements.
