What are the specific contents of the safety regulations for climbing or working at heights? Zhongda Consulting will answer them below.
(1) The term "high-altitude operations" as mentioned in these regulations refers to any operations performed at heights where the fall height is more than two meters (including two meters) above the base level and there is a possibility of falling. The operating height is between 2-2 meters. 5 meters above is called Grade 1 height operation; more than 5 meters to 15 meters is called Grade 2 height operation; more than 15 meters to 30 meters is called Grade 3 height operation; more than 30 meters is called special grade height operation. Working at heights with or without a solid footing is called suspended aerial work.
(2) When formulating the construction or maintenance organization design or construction and maintenance plan, the construction or maintenance unit must list the prevention of falls from heights as an important part of the safety technical measures or organizational measures; for grade 2 or above Special safety technical measures and organizational measures must be formulated for high-altitude operations. After approval by the technical person in charge of the construction or maintenance unit, the truth shall be provided in writing to the construction and maintenance personnel. After the safety measures are implemented, the technical person in charge of the construction site must organize relevant personnel to conduct acceptance inspection and make acceptance records. Those that do not meet the requirements must be modified and qualified before they can be put into use.
(3) Anyone who has been diagnosed by a doctor as having high blood pressure, heart disease, severe anemia, epilepsy and other conditions that are not suitable for working at heights shall not engage in work at heights. Personnel working at heights shall Get an annual physical.
(4) Personnel working at heights must undergo level three safety education and be familiar with these regulations. Special operations personnel must also undergo safety technical training and assessment, and obtain the "Special Operations Operation Certificate" issued by the labor department. Ready to start work.
(5) Personnel working at heights must correctly use personal protective equipment and adopt safety protection measures. They must wear safety helmets when entering the construction site. It is prohibited to go barefoot, wear slippers, high heels, and slip-on shoes with spikes. On rainy days, mud on the soles of shoes must be removed before climbing. When working at high altitudes without protective facilities, safety belts must be worn. Entrances and reserved holes where cross-cutting operations are dangerous must have protective sheds or other isolation measures. Operations with a relative height difference of more than three meters must There are protective railings, baffles or safety nets, safety helmets, and safety nets that must be inspected regularly. If they do not meet international requirements, their use is strictly prohibited.
(6) When encountering severe weather such as strong winds above Level 6, storms, thunder, snow, heavy fog, etc., operations at high altitudes in the open air should be stopped. In the event of thunderstorms or strong winds, when emergency repairs are urgently needed, reliable safety measures must be taken before work at heights can be carried out.
(7) Materials or spare parts used for high-altitude operations must be stacked stably and reliably, and some may require temporary precautions. Tools should be readily placed in tool bags (sleeves). It is prohibited to throw objects when passing them up and down. When it is necessary to throw an object, the people below should be evacuated and a designated person should be designated to supervise it.
(8) Climbing facilities such as movable straight wooden ladders, folding ladders, movable or metal straight ladders must comply with national requirements. Ladders should be strong and reliable, with a block distance of 0.3 meters. There must be no missing blocks. When using The ladder feet should adopt anti-slip measures, and no heightening work is allowed. The angle between a single-sided ladder and the ground is 60-70 degrees. When using a herringbone ladder, the angle between the two pieces should be 60 degrees. The feet of the ladder should be tightened firmly. Two people are not allowed. Operate on the same ladder.
(9) Personnel working at heights must be focused when working. It is strictly forbidden to play and play at the work site, and it is strictly forbidden to work at height while drunk.
(10) Personnel working at heights should not climb up or down derricks, gantry, or scaffolding from the prescribed passages (except when derrick or gantry installers are working), and it is strictly prohibited to ride on non-passenger vertical transportation equipment.
(11) It is prohibited to sit on the edges of protective railings, platforms and holes, and it is not allowed to lie on or rest under scaffolding. In the absence of reliable safety protection measures, it is prohibited to walk or work on unfixed components such as roof trusses, supports, stringers, and walls. Strictly operate on scaffolding poles, balconies, railings, walls, and independent beams.
(12) The safety signs of various safety protection facilities at the construction or maintenance site shall not be moved or dismantled by anyone without the approval of the person in charge of construction or maintenance at the construction site. When construction is suspended and resumed, construction workers at the construction site must inspect various safety protection facilities. Construction will not be allowed if safety requirements are not met.
(13) Before the construction of the demolition project, practical safety technical measures must be formulated and installed only after approval by the technical person in charge of the construction site.
(14) When working up and down in the same vertical plane, a safety isolation layer must be set up. Safety protective sheds must be erected at the entrances and exits of buildings, pedestrian passages near construction or maintenance areas, and ground inlets of vertical transportation equipment.
