    transportation hydrogen sulfide h2s safety poisoning truck trucks automobile poisoning

                                                                                   

                                                                                       

    Hydrogen sulfide is encountered most commonly as an environmental contaminant. It occurs naturally in crude petroleum, natural gas, sour gases, in salt mines, in volcanic gases, hot sulfur springs, lakes, salt water ponds, undersea vents, marine sediments, swamps, stagnant bodies of water, and as an occluded gas in some minerals. It is formed as a result of bacterial breakdown of organic matter containing sulfur and can be formed by bacteria in the digestive tract. It can be found in sewage treatment facilities and in livestock barns and manure. It is also a by-product of many industrial operations, such as petroleum refineries, petrochemical plants, natural gas plants, Kraft paper mills, iron smelters, coke ovens, food processing plants and tanneries. The major industrial use of hydrogen sulfide is in the production of elemental sulfur and sulfuric acid.

    It is also used for the production of thioorganic compounds and sodium sulfide and sodium hydrosulfide; for purification of hydrochloric and sulfuric acids; to replenish sulfide content in Kraft pulping; for the purification of ores by selective flotation; in metallurgy to precipitate copper, nickel and cobalt sulfides from ores; in the removal of copper, cadmium and titanium from spent catalysts; for catalyst activation, such as presulfiding petroleum cracking catalysts, and catalyst poisoning; in the production of extreme pressure lubricants; in the formulation of rare earth phosphors for use in colour television tubes; for treatment of metal surfaces; for passivation of the walls of reactors operating at high temperatures in petroleum operations; to form a layer of sulfide on the surface of steel wires or plates that are to be coated with paint or plastic; in the production of heavy water for the nuclear industry; in analytical chemistry; and as an additive in cutting oils.

    Inhalation Effects of H2S Hydrogen sulfide (H2S) is a very toxic gas at normal temperatures. It poses a very serious inhalation hazard.

    • 1-5 ppm - Moderately offensive odour, possibly with nausea, or headaches with prolonged exposure.
    • 20-50 ppm - Nose, throat and lung irritation, digestive upset and loss of appetite, sense of smell starts to become "fatigued".
    • 100 -200 ppm - Severe nose, throat and lung irritation, ability to smell odour completely disappears.
    • 250-500 ppm - Potentially fatal build-up of fluid in the lungs (pulmonary edema) in the absence of central nervous system effects (headache, nausea, dizziness), especially if exposure is prolonged.
    • Prolonged exposure (for several hours or days) to concentrations as low as 50-100 ppm can cause a runny nose, cough, hoarseness, and shortness of breath. Prolonged exposure to higher concentrations can produce bronchitis, pneumonia and a potentially fatal build-up of fluid in the lungs (pulmonary edema).

      Things to Remember-

    • Before crude oil or condensate is loaded onto trucks for transportation, it is important to know the hydrogen sulfide content for the safety of the truck operator as well as other motorists on the road.

                                                                                    

                                                                                            

    • Due to the toxicity of hydrogen sulfide, corrosion of pipelines and tanks can occur over time if transporters are not aware of H2S content.

    H2S CAN BE FOUND IN THE TRANSPORTATION OF:   

    • Septic tank drainage/sewage
    • Asphalt (black top) for driveways
    • Petroleum based products such as gasoline, oil, diesel fuel, and kerosene.
    • Agricultural manure or fertilizers that contain organic matter that is decomposing.

    TRANSPORTATION CHARACTERISTICS:

    • A colorless gas having a strong odor of rotten eggs. Boiling point -60.2°C. Shipped as a liquid confined under its own vapor pressure. Density (liquid) 8.3 lb / gal. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Gas is very toxic by inhalation. Fatigues the sense of smell which cannot be counted on to warn of the continued presence of the gas. Prolonged exposure of closed containers to heat may result in their violent rupturing and rocketing.
    • Rate of onset: Immediate & Delayed
    • Persistence: Minutes to hours
    • Odor threshold: 0.1 ppm
    • CAS Number 7783-06-4
    • UN/NA Number 1053
