What are the regulations for safety protection when working at heights?

1. The purpose is to ensure the safety of high-altitude operations involved in factory construction and maintenance and other work and to prevent accidents. These regulations are specially formulated. 2. Scope of application These regulations apply to the safety management of high-altitude operations in factory construction and maintenance. 3. Definitions This standard adopts the following definitions: 3.1 Work at heights Any work performed at heights 2m or above from the reference plane of the fall height, where there is a possibility of falling, is called work at heights. 3.2 Fall height datum plane The horizontal plane from the working position to the lowest fall landing point is called the fall height datum plane. 4 Grading and classification of high-altitude operations 4.1 Grading of high-altitude operations High-altitude operations are divided into first-level, second-level, third-level and special-level high-altitude operations. 4.1.1 When the operating height is between 2m and 5m, it is called first-level high-altitude operation. 4.1.2 When the operating height is between 5m and 15m, it is called secondary high altitude operation. 4.1.3 When the operating height is between 15m and 30m, it is called Level 3 high altitude operation. 4.1.4 When the operating height is above 30m, it is called special high altitude operation. 4.2 Classification of high-altitude operations High-altitude operations are divided into special high-altitude operations and general high-altitude operations. 4.2.1 Special high-altitude operations a. Strong-wind high-altitude operations carried out when the gust wind is level 6 (wind speed 10.8m/s) and above. b. Work at high altitudes in snowy weather during snowfall. c. Work at heights on rainy days when it rains. 4.2.2 General high-altitude operations except special high-altitude operations. 5. Objective risk factors that directly cause falls. Each enterprise should strictly control the following objective risk factors that directly cause falls, and take practical and effective measures to prevent falling accidents from heights. 5.1 Wind gust level six (wind speed 10.8m/s) and above; 5.2 The working time is up to 4 hours when the temperature is above 25℃; 5.3 Outdoor environment with the temperature below 10℃; 5.4 There is ice, snow, frost, water, Oil and other slippery objects; 5.5 Insufficient natural light and poor visibility; 5.6 Approaching or contacting dangerous voltage charged objects; 5.7 Swinging, the footing is not flat or has only a small flat surface, causing the operator to be unable to maintain a normal posture; 5.8 Rescue a sudden incident Various disasters and accidents; 5.9 personnel carry objects exceeding 15KG at a time. 6 Basic requirements for high-altitude operations 6.1 Units engaged in high-altitude operations must have the qualifications for high-altitude operations and must implement safety protection measures before construction. 6.2 All personnel engaged in high-altitude operations must undergo safety education and be familiar with the site environment and construction safety. People with occupational contraindications (hypertension, heart disease, severe anemia, fear of heights, etc.) and those who are old and frail, overtired, have poor eyesight, and those who are drunk are not allowed to work at heights. People who are low in energy, anxious, or overly excited are not suitable for working at heights for the time being. 6.3 Personnel working at heights should wear labor protection supplies in accordance with regulations, conduct inspections before operation, and use anti-fall supplies and climbing appliances and equipment correctly during operations. 6.4 Safety guardians should be assigned to monitor workers working at heights, and safety guardians should stick to their posts. 7 Management requirements for operations at height 7.1 Requirements for safety technical measures Various safety technical measures required for operations at height should be planned in advance and included in production preparations. The enterprise's technical department is responsible for formulating safety technical measures for working at heights, the production management department is responsible for organizing and implementing them, the user department is responsible for daily maintenance and 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 Make preparations before construction at high altitudes. In case of severe weather (strong wind, heavy rain, heavy snow) or dangerous factors in or near the workplace (high-voltage wires; release of toxic and harmful gases) ; When there is high-temperature steaming or smoke eruption; when there are ice, snow, frost, water, oil and other slippery objects on the construction site), it is prohibited to arrange construction. 7.2.2 Clarify the construction content and operation sequence, implement the safety facilities required for construction (scaffolding, lighting, etc.) to meet construction safety requirements. 7.2.3 Whenever there is mixed upper and lower operations during construction, coordination and contact should be made in advance. During the operation, the scope of responsibilities of each position should be clarified, mutual contact should be strengthened, and coordination should be done well. 7.2.4 During the operation, the unsafe behavior of personnel working at heights and the unsafe state of objects should be monitored.

7.2.5 After the operation, the workers should be urged to do a good job in civilized production at the construction site, and the construction safety facilities should be inspected, including: safety railings, covers, safety nets and scaffolding. 8 Safety protection and requirements for working at heights 8.1 The basic safety management regulations of "three musts", "six don'ts" and "ten don't climb heights" in the safety regulations for working at heights must be followed. 8.1.1 "Three must-haves": ① If there is a hole, there must be a cover; ② If there is a side, there must be a fence; ③ If there is no cover or fence around the hole, there must be a net. 8.1.2 "Six Don'ts": ① Do not throw objects down; ② Do not turn your back on the escalator; ③ Do not wear slippers, sandals, high heels; ④ Play or sleep; ⑤ Do not lean on the escalator Temporary handrails or railings; ⑥ Do not operate when the safety belt is not fastened. 8.1.3 "Ten Do not Climb": ① Do not climb if you have contraindications; ② Do not climb if you are not authorized or approved; ③ Do not climb if you do not wear a safety helmet or fasten a safety belt; ④ Do not climb scaffolding boards, springboards, and ladders.
