Hydrogen Sulfide Awareness

safety officer course in rawalpindi

Hydrogen sulfide is an often ignored, yet potentially dangerous presence when drilling an oil well. It's presence in the ground can lead to corrosive effects on drilling equipment and additionally can pose a serious risk to health. It can range from being a minor health and equipment annoyance to being a full fledged, serious health risk for rig workers. Understanding this about this gas can help save the lives and ensure the wellness of rig operators and employees by safety officer course in rawalpindi.

Hydrogen sulfide gas, commonly referred to as H2S, builds up in the soil from decaying organic material, usually plant life, and is often times released when drilling deep into the ground for things like water wells and oil wells. The gas, in parts per million of 10 - 100 can smell like rotten eggs. Once you go above 100 parts per million, or ppm as it is commonly known as, it starts to irritate the mucous membranes, eyes and throat. As the levels of hydrogen sulfide exposure increase, so does the risk of bodily injury and illness. The side effects become intolerable and can result in unconsciousness, brain damage and even death in the 500 - 1000 ppm range. It is highly recommended that rig workers take safety classes for dealing with these hazards first hand. For more detailed training for safety officer course in rawalpindi is the best option

Products that can bring H2S levels under control help preserve drilling equipment from its highly corrosive effects and help workers by creating a safer environment. Products that do these functions are usually referred to in the chemical industry as H2S scavengers. There are several scavengers made by multiple chemical manufacturers and supply houses. There are typically two types of scavengers made, regenerative and non-regenerative. The difference is that regenerative scavenging uses a system that absorbs the H2S and the active chemical scavenger is heated which enables it to be reused. The H2S then goes through a process to make it take the form of sulfur, thus eliminating the threat. Non-regenerative scavengers are applied as a continuous, inline injection method or as a batch treatment sequence.

Which well has h2s and which not, this will only be understood if you participate in safety officer course in Islamabad for Some oil wells may never run into significant toxic gas problems where other wells will see extremely high concentrations of toxic, corrosive gasses. When gas concentrations reach hazardous and highly corrosive levels, drilling and production must be terminated to deal with the gas and neutralize it safely and efficiently as possible. Extremely high levels of hydrogen sulfide in a well can cause delays of up to two days in some cases to eliminate all the gas, which is both water and oil soluble.

Taking the precautionary measures to monitor toxic gas levels and following safety protocols ensures a safe work environment and is an important task which is often learned by taking the appropriate safety class. Having at least one experienced employee on the rig with hands on experience is a benefit to his fellow workers.
