The number of existing special equipment operators in the country was 8,829,900, an increase of 17.52% over 2017, of which 1.63 million were issued in 2017.
(3) Safety monitoring and inspection of special equipment.
By the end of 2018, the national quality inspection system had set up 3,236 special equipment safety supervision institutions, including one at the national level, 32 at the provincial level, 485 at the municipal level, and 2,718 at the county level. There were 12,491 national special equipment safety supervisors.
By the end of 2018, there were 513 comprehensive inspection facilities for special equipment in the country, including 323 inspection agencies affiliated to quality inspection departments, and 190 industry inspection agencies and enterprise self-inspection agencies. There are also 37 type test institutions, 336 non-destructive testing institutions, 1817 gas cylinder inspection institutions, 179 safety valve calibration mechanisms, 85 building construction sites and municipal engineering site crane inspection institutions; various inspection agencies The total number of personnel licenses is 71,765.
In 2018, the quality supervision departments at all levels in the country carried out 1,201,300 person-times of special equipment law enforcement supervision and inspection, and issued 155,700 safety supervision orders. The special equipment inspection agency supervised and inspected the manufacturing process of 1,393,100 sets of special equipment and components, and found and urged the enterprise to handle 66,200 quality and safety issues; supervised and inspected the installation, renovation and maintenance of 2.0534 million special equipments. It discovered and urged enterprises to deal with 344,500 quality and safety issues; conducted a regular inspection of 4,756,600 units of special equipment, and found and urged the use of units to handle 1,108,700 quality and safety issues.
Second, the safety status of special equipment
(1) The overall situation of the accident.
In 2018, there were 227 special equipment accidents, 289 deaths and 274 injuries. No major accidents occurred in special equipment throughout the year. Compared with 2012, the number of accidents decreased by one, down by 0.44%; the number of deaths decreased by 3, down by 1.03%; the number of injured decreased by 80, down by 22.60%. The number of deaths per unit of equipment in the country was 0.46, a decrease of 11.03% compared with 2012, and the control target of 10,000 units of equipment deaths issued by the State Council Security Committee did not exceed 0.51. Overall, the national security situation of special equipment is generally stable.
