1, in order to ensure the safety of aerial work involved in factory construction and maintenance and prevent accidents, this regulation is specially formulated. 2. Scope of Application These Provisions are applicable to the safety management of aerial work in factory construction and maintenance. 3. Definitions The following definitions are adopted in this standard: 3. 1 work at height. Working at heights that are 2m or more away from the reference plane of falling height and may fall is called working at heights. 3.2 The reference plane of falling height is the horizontal plane from the working position to the lowest falling point, which is called the reference plane of falling height. 4. Classification and classification of work at height 4. 1 Classification of work at height The work at height is divided into Grade I, Grade II, Grade III and Grade III. 4. 1. 1 When the working height is 2m to 5m, it is called first-class aerial work. 4. 1.2 When the working height is above 5m to 15m, it is called secondary aerial work. 4. 1.3 When the working height is above 15m to 30m, it is called three-level aerial work. 4. 1.4 When the operating height is above 30m, it is called ultra-high operation. 4.2 Classification of aerial work Aerial work is divided into special aerial work and general aerial work. 4.2. 1 Special operation at heights A. Work at heights with strong winds above gust level 6 (wind speed10.8m/s). B. Work aloft on snowy days during snowfall. C. aerial work in rainy days. 4.2.2 General high-altitude operations except special high-altitude operations. 5 objective risk factors that directly lead to falling from a height All enterprises should strictly control the following objective risk factors that directly lead to falling from a height and take practical and effective measures to prevent falling from a height. 5. 1 gust wind force 6 (wind speed10.8m/s) and above; 5.2 Working at above 25℃ for 4 hours; 5.3 Outdoor environment with temperature lower than 65438 00℃; 5.4 There are slippery objects such as ice, snow, frost, water and oil on the construction site; 5.5 Insufficient natural light and poor visibility; 5.6 Close to or in contact with dangerous voltage charged bodies; 5.7 When swinging, the foothold is uneven or there is only a small plane, which makes the operator unable to maintain the normal posture; 5.8 rescue all kinds of disasters and accidents that suddenly happen; 5.9 personnel handling 15KG or more at a time. 6 Basic requirements for working at heights 6. 1 Units engaged in working at heights must have the qualification for working at heights and implement safety protection measures before construction. 6.2 All personnel engaged in aerial work must receive safety education and be familiar with the site environment and construction safety. For people with occupational contraindications (hypertension, heart disease, severe anemia, acrophobia, etc. ), old and weak, overworked, poor eyesight, drunk, etc. , aerial work is not allowed. People who are depressed, in a state of panic and anxiety and over-excited are not suitable for aerial work for the time being. 6.3 Workers working at heights shall wear labor protection articles according to regulations, check before operation, and correctly use anti-falling articles and climbing appliances and equipment during operation. 6.4 Safety guardians shall be set up for aerial work to supervise aerial work personnel, and the safety guardians shall stick to their posts. 7 Management requirements for work at height 7. 1 Safety technical measures All kinds of safety technical measures required for work at height should be planned in advance and incorporated into production preparation. The technical department of the enterprise is responsible for formulating safety technical measures for working at heights, the production management department is responsible for organizing the implementation, the user department is responsible for daily maintenance management, and the safety supervision department is responsible for the inspection and acceptance of safety technical measures. 7.2 Safety requirements for production organization personnel 7.2. 1 Prepare for aerial work before construction. In bad weather (strong wind, heavy rain, heavy snow) or dangerous factors in the workplace and nearby (high-voltage wires; Release of toxic and harmful gases; There is high temperature steam and smoke eruption; When there are slippery objects such as ice, snow, frost, water and oil on the construction site, it is forbidden to arrange construction. 7.2.2 Define the construction content and operation sequence, and implement safety facilities (scaffolding, lighting, etc.). ) construction needs, meet the construction safety requirements. 7.2.3 When mixing up and down in construction, it is necessary to coordinate and contact in advance, clarify the responsibilities of each post in the operation process, strengthen mutual contact and do a good job of coordination. 7.2.4 In the process of operation, the unsafe behavior of workers working at heights and the unsafe state of objects shall be supervised. 7.2.5 After the operation, urge the operators to do a good job in civilized production on the construction site and check the construction safety facilities, including safety railings, cover plates, safety nets and scaffolding. 8.
