Excessive levels of hydrogen sulfide in the vapor phase above residual fuel oils in storage tanks can result in health hazards, violation of local occupational health and safety regulations, and public complaint. An additional concern is corrosion that can be caused by the presence of H2 S during refining or other activities. Control measures to maintain safe. levels of H2 S require a precise method for the measurement of potentially hazardous levels of H2 S in fuel oils. Hydrogen sulfide (H2S) is a very dangerous, toxic, explosive and flammable, colourless, and transparent gas which can be found in crude oil and can be formed during the manufacture of the fuel at the refinery and can be released. during handling, storage, and distribution. At very low concentrations, the gas has the characteristic smell of rotten eggs. However, at higher concentrations, it causes a loss of smell, headaches, and dizziness, and at very high concentrations, it causes instantaneous death. It is strongly recommended that personnel involved in the testing for hydrogen sulfide are aware of the hazards of vapor-phase H2 S and have in place appropriate processes and procedures to manage the risk of exposure.
