H2S Training for Workers

1. INTRODUCTON H2S is a toxic (poisonous) gas that can kill you if you breathe it. It is present at almost every phase of the oil and gas extraction process, so whether you work on a drilling rig or any hydrocarbon processing plant, you’re never far away from this deadly gas. Just a small quantity of H2S can render a person unconscious or even dead. But, if we know the dangers and implement the required control measures/ emergency procedures, we can work safely with H2S. It is a gaseous compound generated by the decomposition of organic matter, i.e. microorganisms, human and animal waste (sewage) breaking down without Oxygen (O2) being present. H2S is a combination of 2 hydrogen atoms and 1 sulfur atom. H2S has many names. These include: Devil’s Breath, Rotten Egg Gas, Sewer Gas, Sour Gas, Stink Damp, Silent Killer, and Swamp Gas.

2. Different Sources of H2S H2S can be found at nearly all of Saudi Aramco operations locations & facilities: o Oil, Gas & Water Wells o Pipelines o Gas Plants and GOSPs o Production Tanks and Facilities o Sulfur Plants o Sewers o Flare Pits

3. Characteristics, Hazards and Physical Properties of H2S

4. Effects of Hydrogen Sulfide on the Body There are several factors that can affect how an individual reacts to H2S. These are: o Duration of exposure to H2S o Concentration of H2S in atmosphere o Frequency of exposure to H2S o Body resistance to H2S effects Physical characteristics affect ones vulnerability to H2S. Height, weight, and health are factors. Other influences are age and habits such as smoking. Concentration and duration also play important roles. Exposure to chemicals and an individual’s health also affect vulnerability. Always remember that the safest way to deal with H2S is to avoid it.

5. Fixed and Man-Portable Gas Detection and Monitoring Equipment Every Confined space is required to have the following five different types of detectors for H2S and other toxic and flammable substances: o Fixed Monitors o Portable Monitors o Personal Gas Monitors o Handheld Pump Detectors o Draeger Test Kit

6. Emergency Procedures including Rescue and First Aid Techniques Emergency Procedures A well site emergency response plan is required for every wellsite, and is typically prepared by Safety Engineer. One safe briefing area must be positioned upwind from potential H2S release points at all times All personnel report to the upwind designated area when an H2S gas release occurs A headcount is completed as per the Station Bill or persons onboard list (POB). Do not attempt to rescue anyone - both of you may die First Aid and Rescue Procedures Sound the alarm Get out of the area Assess situation (Perform a head count and beware of other hazards) Call medical aid Rescue the casualty

7. Breathing Apparatus o Emergency Escape Breathing Apparatus o Supplied Air Breathing Apparatus (SABA) o Self-Contained Breathing Apparatus (SCBA)
