First, the leakage of toxic gas hydrogen sulfide contingency rapid withdrawal of staff from air leakage supremacy wind, and immediately isolate the gas alarm, the small leakage isolation 150m, Leakage isolation 300m, strict restrictions on access. Cut off the source of fire. The proposed emergency personnel wearing self-Pressurized respirators to wear protective clothing. From upwind to enter the scene. As much as possible to cut off the source of leakage. Reasonable ventilation, accelerated proliferation. The water-spray diluted solution. Build a causeway or trenching asylum produce a large amount of wastewater. If possible, the residual gas or use exhaust gas leakage sent washing tower or towers connected fume hood. Or make it by ferric chloride aqueous solution, piping installed to return devices to prevent the solution was sucked back. Leak containers should be properly handled, repair, testing later use. Second, the toxic gas hydrogen sulfide protective measures respiratory protection: concentration in air overweight, they should wear the transition type (half-mask). Emergency rescue or evacuation, it is recommended to wear a the oxygen respirator or air respirators. Eye Protection: Wear chemical safety glasses. Physical protection: wear antistatic overalls. Hand protection: Wear gloves against chemicals. Other: no smoking scene work, eating and drinking. After work, take a shower. Timely changed or washed overalls. Workers should learn self-help and mutual aid. Enter the tank, restricted space or other high-concentration area operations, someone custody. Third, the toxic gas hydrogen sulfide aid measures Skin contact: Remove contaminated clothing, mobile water rinse. Medical treatment. Eye contact: immediately filed eyelid, with a large number of mobile water or saline thoroughly washed at least 15 minutes. Medical treatment. Inhalation: rapidly from the scene to fresh air. To keep the airway open. If breathing is difficult, give oxygen. If breathing has stopped, artificial respiration. Medical treatment. Fire fighting methods: firefighters must wear fire protective body suits. Cut off gas supply gas alarm. If not immediately cut off the gas source is not allowed to extinguish burning gas. Cooling water containers, if possible containers from the scene empty Department. Extinguishing Media: water spray, foam, carbon dioxide, dry powder.
