Hydrogen Sulphide (H2S) is the single biggest killer of workers in the oil & gas industry FACT!! Have you considered all the risks involved in operating in a known H2S area?
A few simple questions for you to consider:
Are you working in a known H2S geographical zone, is there a history of H2S in this area?
Is the reservoir location that you are working to located within a known geological formation that may contain H2S?
Will your operations increase the risk of H2S being released to atmosphere where the workforce will be present?
Do all personnel need to be working / located in the area?
Have you taken all the engineering steps to negate the risk of exposing the work force to H2S or other non-life supportive atmospheres?
Does your evacuation plan take into account the possibilities of increasing toxic hazards around your primary evacuation routes?
