Gas production

Gas production - production of combustible gas for industrial and household purposes. The main occupational hazards in gas production are dust and toxic substances. Dust occurs when crushing, shredding, sorting of coal. Toxic substances are released during gasification by incomplete combustion of fuel, cooling, and allocation of water vapor from the received gas, gas cleaning from heavy hydrocarbons by the method of leaching in oils, the removal of ammonia, cyanide compounds, carbon dioxide and hydrogen sulfide. The most toxic components of gas are carbon monoxide and hydrogen sulfide. The concentration of carbon monoxide in the shops and factories can reach 20 mg/m3 or more, which can lead to occupational poisoning, acute and chronic (see carbon Monoxide).
The improvement of working conditions is achieved through the elimination of harmful factors of working environment. For dust control use of hiding places dust and its suction; combating excessive heat through aeration and mechanical ventilation, use of mobile dusiruumi systems with chilled using sprayed water air. Great importance is the device places or rest cabins with submission of the cooled air. Necessary works mechanization in the repair of cameras and regenerators. Of particular importance is the struggle against gas release: sealing equipment, in particular chamber furnaces, pipelines, remote control, good ventilation. Necessary adoraria gas mercaptans for organoleptic control of his presence in the air, as well as neutralization of condensate and wash water because of their high toxicity. Mandatory monitoring of the air environment (pollution CO) using rapid techniques. Required periodic medical examinations of employees. Cm. also Gas-producing shop.
