Analysis on current situation of chemical poisons and emergency rescue in an aircraft maintenance warehouse in Guangzhou City
Objective To understand the current situation of chemical poisons and emergency rescue facilities in an aircraft maintenance warehouse in Guangzhou City,and put forward improvement suggestions to effectively prevent occupational hazards.Methods In September 2022,during the normal production stage of the enterprise,the current situation of chemical poisons and emergency rescue facilities in an aircraft maintenance warehouse in Guangzhou City was investigated and analyzed by occupational health investigation,occupational health testing,field experiment and other methods.Results The concentration of toluene in each production workshop of the aircraft maintenance depot was<0.16-1.20 mg/m3,the concentration of xylene was 0.26-1.20 mg/m3,the concentration of ethylbenzene was 0.09-1.60 mg/m3,and the concentration of isopropanol was<0.13-18.00 mg/m3.The detection results of the concentration of other chemical toxins were all below the 10％occupational exposure limit(OELs).Harmful factors that may lead to occupational disease hazards included chemical irritants,sulfuric acid,phosphoric acid,potassium hydroxide,hydrogen sulfide and ammonia.Possible occupational hazard accidents included eye,skin irritation,chemical skin burns,chemical eye burns,acute hydrogen sulfide poisoning,and acute ammonia poisoning.Conclusions The current situation of chemical poisons and emergency rescue in this aircraft maintenance warehouse in Guangzhou City is not optimistic.In response to possible occupational hazards and accidents,enterprises should continue to improve and maintain emergency rescue facilities,strengthen emergency drills,improve emergency management ability,and effectively prevent employees from occupational injuries.
