Countermeasures for mine control dangers and hazards
First, improve the production process, implement mechanization and automated production.
Second, the installation of security devices, such as protective devices, insurance devices, signal devices and dangerous signs and identification signs.
Third, the mechanical strength test. On the one hand, the mechanical strength is ensured by design calculation; on the other hand, the preventive mechanical strength test is carried out at regular intervals (the mechanical load is subjected to a test load higher than the working load, and if the test object is not damaged during the test time, Residual deformation or other defects are considered qualified and permitted to operate).
Fourth, to ensure electrical safety and reliability, including safety certification, backup power, anti-shock, electrical fire and explosion prevention, anti-static measures.
5. Maintain and repair machinery and equipment as required.
6. Maintain a reasonable layout of the workplace. According to the ergonomics requirements, the machinery and equipment are installed to conform to the workers' operating habits, and the operation is convenient, so that the lines through which the processed articles pass are the shortest; the distance between the working places, the equipment and the walls and columns of the building To meet safety requirements; all the boxes, cabinets, shelves, etc. that store tools, blanks, and finished products in the workplace; keep the workplace clean and level.
7. Equipped with personal protective equipment. Special labor protection products must use products obtained by enterprises that have obtained the production license for special labor protection products issued by the national designated agency. The products should have safety appraisal certificates. Anti-poisoning products must be strictly managed and uniformly washed, disinfected, stored and destroyed.
