암모니아에 대한 사고대응 정보시트 개발 = Development of Accident Response Information Sheets for ammonia

다국어 초록 (Multilingual Abstract)

We analyzed the demand of competent authorities requiring adequate technical information for initial investigation of chemical accidents. Reflecting technical reports on chemical accident response by environmental agencies in the U.S. and Canada, we presented information on environmental diffusion and toxic effects available for the first chemical accident response. The ammonia can explode if it heats with the extremely inflammable. In case of causing the damage in the burn and eye which is severe in the skin and inhaling it is harmful to the human body but the ammonia entered through the breathing is mostly again ejected through the breathing. The reaction characteristic reacts with the acid and oxide material. And if the reaction characteristic applies heat, the reaction characteristic is disassembled and can produce the toxic hum and nitric oxide and erode the copper and surface of the zinc and metal. In case of ammonia leak, the preventive measures are to decrease steam generation in exposed sites, prevent the transfer of vapor cloud and promptly respond using inflammable substances including acetic acid solution, ground limestone, dried soil, dry sand, vermiculite, fly ash and powder cement. The method for fire fighting is to suppress fire with manless hose stanchions or monitor nozzles by wearing the whole body protective clothing equipped with over-pressure self-contained breathing apparatus from distance. In case of transport accident accompanied with fire, evacuation distance is 1,600m radius. In cae of fire, fire suppression needs to be performed using dry chemicals, CO2, water spray, water fog, and regular fog etc. The major symptoms by exposure route are dyspnoea, bronchitis, chemical pneumonia and pulmonary edema for respiration, skin laceration, dermatitis, burn, frostbite and erythema for eyes, and nausea, diarrhea, stomachache, and tissue destruction for digestive organs. In atmosphere, its persistency is low, and its bioaccumulation in aquatic organism is also low.
