Hydrogen sulfide (H2S) is a vital component of oil and gas upstream production, where Hydrogen sulfide is naturally generated in situ from reservoir and from sulfate-containing minerals through microbial sulfate reduction and (or) thermochemical sulfate reduction. On the other hand, the technologies employed in oil and gas production, especially from unconventional resources, also can contribute to generation or delay of appearance of Hydrogen sulfide. Human health effects of exposure to hydrogen sulfide, an irritant depend of the concentration of the gas and the length of exposure. Hydrogen sulfide acts similarly to hydrogen cyanide, interfering with cytochrome oxidase and with aerobic metabolism. Essentially, hydrogen sulfide blocks cellular respiration, resulting in cellular anoxia, a state in which the cells do not receive oxygen and die. The human body detoxifies hydrogen sulfide by oxidizing it into sulfate or thiosulfate by hemoglobin-bound oxygen in the blood or by liver enzymes. Lethal toxicity occurs when H2S is present in concentrations high enough to overwhelm the body’s detoxification capacity. Hydrogen Sulfide gas is very corrosive and causes metals to become brittle. Therefore, employers need to take special precautions when choosing equipment when they may reasonably expect to encounter H2S. This may include appropriate H2S trimming of equipment. The recommendations and employee instruction will vary depending on the type of area. The effect of Hydrogen sulfide on the employers’ health and the environment of oil and gas industrial locations will be studied in this research taken Meliatha oil and gas location as a model example for this study. The results showed that following safety instruction can eliminate or reduce all types of accidents including H2S accidents
