Analysis and Countermeasures of occupational hazards in sewage (ethylene) treatment plant - preventive measures (4)

A) carry out HSE education, make full use of radio, television, newspapers, blackboard newspapers, local areas and other publicity tools, and vigorously publicize the occupational disease prevention and control law and the occupational hazards and prevention knowledge of sewage treatment plant; Carry out safety prevention education through various forms such as special education and team safety activities, strengthen the employees' understanding of the occupational hazards of benzene and other toxic factors in the sewage treatment plant, and improve the employees' self-awareness and prevention ability

b) strengthen management and assessment to ensure that personal protective equipment is used in place. They provide some large companies (such as Boeing) with composite materials required for the production of fuselage, wings and aircraft interior, and take proper precautions

c) the personnel with low white blood cell count in the blood should be changed, so that they can temporarily leave the place with occupational hazards, and medical supervision should be strengthened. The national aluminum output is 3.28 million. The experimental machine should be installed in a clean, dry and uniform temperature house. At the same time, the possibility of long beam zigzag experiment on the machine and the possibility of using a mirror extensometer for experiment should be considered. If necessary, further examination should be made

d) formulate prevention and control measures for toxic hazards and strictly implement them. On the premise of meeting the production requirements, use non-toxic or low toxic reagents instead of toxic 1-eye clear reagents; The analysis and test workshop is isolated from the office and rest room, and eating in the workshop is strictly prohibited; Control the escape of poisons and reduce the concentration of poisons. All operations and tests that can produce irritant or toxic gases must be carried out in the fume hood, and the indoor ventilation must be maintained; When operating in the unit area or collecting sewage samples, special protective masks and gloves should be worn to avoid direct exposure to poisons; Carry out mass sports activities and more outdoor exercises to improve the body's immunity

e) improve the working site environment. The dehydration plant that produces a lot of odor shall be treated, and the transformation measures such as isolation and closure, ventilation and deodorization, and fixed-point discharge shall be taken to isolate the working environment of employees from the odor pollution source
