General knowledge of maintenance of aerial work safety of mobile tower

1. Common knowledge of safety inspection for working at heights

1. Working at heights where falling height is 2m (including 2m) is likely to fall is called working at heights.

2, before aerial work, must carry on the dangerous point analysis, formulate preventive measures. 3, before aerial work, carefully check the safety protection facilities.

if you check whether the hoisting equipment is safe and reliable, and whether the braking, safety devices and protection devices of the hoisting machinery are safe and reliable, you should handle the problems in time. 4. Safety fences and warning signs should be set up at the aerial work place to stop pedestrians and vehicles from passing and avoid falling objects from hurting people.

5. When working high above the ground, always wear the safety helmet on your head, and don't take it off casually. 6. When working high above the ground, you must use your seat belt. The hook or rope of your seat belt should be hung on a solid component or a wire rope specially designed for your seat belt.

stop hanging on moving or unstable objects.

2. What safety precautions should be paid attention to when working at height

1. The hook or rope of the safety belt should be hung on a solid component or a steel wire rope specially designed for hanging the safety belt.

do not hang on moving or unstable objects. 2. Tool bags shall be used for work at heights.

Larger tools should be tied to solid components with ropes, and they are not allowed to be randomly placed to prevent accidents caused by falling from high altitude. 3. When working at heights, no one is allowed to walk or stay below the workplace except the relevant personnel. Fences or other protective devices should be installed below the workplace to prevent falling objects from hurting people.

if you work on a grating platform, you should lay wooden boards to prevent tools and equipment from falling. 4. Tools and materials are not allowed to be thrown up and down. They should be hoisted down or up after being fastened with ropes, so as not to injure the staff below or destroy the scaffolding.

5. When the upper and lower floors are working at the same time, a tight and firm protective partition, shed or other isolation facilities must be erected in the middle, and the staff must wear safety helmets.

3. What are the basic provisions of safety measures for working at heights?

The basic provisions of safety measures for working at heights are as follows: (1) The safety technical measures for working at heights and the required materials and tools must be included in the construction organization design of the project.

(2) The person in charge of unit project construction shall be responsible for the safety technology of working at heights of the project and establish the corresponding responsibility system. Before construction, safety technical education and delivery should be carried out step by step, and all safety technical measures and personal protective equipment should be implemented. Construction is not allowed without implementation.

(3) Safety signs, tools, instruments, electrical facilities and all kinds of equipment in high-altitude operations must be checked before construction to confirm that they are in good condition before they can be put into use. (4) Climbing and hanging high-altitude operators and those who set up safety facilities for high-altitude operations must pass professional technical training and professional examinations, hold relevant certificates, and must.

have a regular physical examination. (5) When defects and hidden dangers are found in the safety technical facilities for working at heights during construction, they must be solved in time; When personal safety is endangered, the operation must be stopped.

(6) All objects that may fall in the construction workplace should be removed or fixed first. Materials used in high-altitude operations should be piled up smoothly, which may hinder the passage and loading and unloading.

tools should be conveniently put into the tool bag; The walkways, access boards and climbing appliances in operation shall be cleaned at any time; Dismantled objects, surplus materials and waste materials shall be cleaned and transported away in time, and shall not be randomly placed or discarded downwards. It is forbidden to throw the transferred objects.

(7) When working at heights in rainy and snowy days, reliable anti-skid, anti-cold and anti-freezing measures must be taken. All water, ice, frost and snow should be removed in time.

lightning protection facilities should be set in advance for high-rise buildings working at heights. In case of severe weather such as strong wind and dense fog below level 6, open-air climbing and hanging high-altitude operations are not allowed.

after the snowstorm and typhoon rain, the safety facilities for working at heights should be inspected one by one, and if they are found to be loose, deformed, damaged or falling off, they should be repaired immediately. (8) When the safety protection facilities are temporarily dismantled or changed due to the necessity of operation, it must be approved by the construction director, and corresponding reliable measures shall be taken, and the operation shall be resumed immediately.

(9) When the protective shed is erected and dismantled, a warning zone should be set up, and special personnel should be assigned to monitor it. It is strictly forbidden to dismantle it from top to bottom at the same time.

(1) The mechanical calculation of the main stress bars of the safety facilities for working at heights is based on the general structural mechanics formula, and the strength and deflection are calculated according to the current relevant codes. However, the strength calculation of steel flexural members does not consider the plastic effect, and the structure should meet the requirements of the current corresponding codes. .

4. What are the main safety precautions for aerial work in communication engineering?

1. Personal injury prevention, falling prevention and anti-skid accidents. 1. During winter construction, strengthen labor protection. Construction personnel should wear gloves and rubber-soled shoes, increase anti-skid measures, and it is forbidden to wear hard-soled shoes.

second, you must wear a safety helmet when entering the construction site, and the cold hat cannot replace the safety helmet; Three, outdoor work should be equipped with cold-proof articles, and the "probe board" should be carefully prevented from stepping on the frame. For aerial work, the safety belt should be hung. On the horse stool with a height of more than 1.5 meters, one person should operate and one person should monitor it. Four, climbing workers must wear anti-skid shoes, protective gloves and other anti-skid and anti-freezing measures, must fasten your seat belt; 5. Tower crane installation and jack-up operations are prohibited in strong winds above level 4, and hoisting operations and aerial work are prohibited in strong winds above land level; When the steel cables used for binding and lifting steel members on land and at negative temperature are in direct contact with the members, anti-skid spacers should be set. Check whether the wire rope of the hanging object is damaged, whether the U-shaped clamp is locked and whether the hook insurance is effective; Paint, because the materials are brittle and easy to slide in winter, so the tools for lifting large tonnage goods should have a greater safety factor to fully ensure safety; Right, in case of bad weather such as rain and snow, the accumulated water and snow on the construction site should be removed in time, and it is strictly forbidden to organize construction forcibly in rain, snow and windy weather.

2. Fire prevention and poisoning accident prevention 1. To prevent fire, fire-fighting facilities and equipment should be complete, intact and usable, and inflammable and explosive articles should not be piled up in the computer room (base station); Second, the security officer should regularly check the power supply and fire prevention on the construction site to prevent communication, fire accidents and theft; Three, it is forbidden to open fire to keep warm at the construction site, especially the construction site, once found, will be severely punished; Four, before the manhole operation should be "one pass, one inspection": (a) before the manhole operation, the manhole covers at the front and rear of the operation area should be opened and ventilated first. (2) Check whether there is poisonous gas and harmful gas in the manhole to ensure the safety in the manhole.

5. When working in a manhole, it must be "one wearing, one looking, two forbidding and three forbidding": (1) Operators should wear safety helmets, waterproof pants and rubber boots. (2) Outside the well (above), there should be a special guard.

Before the optical (electric) cable is cut, relocated or torn down, it is necessary to make a detailed plan and steps for cutting, relocating or tearing down the old, make a thorough analysis, carefully survey the on-site resources and verify the data of cutting, relocating or tearing down the old, and determine the plan, steps and methods for cutting, relocating or tearing down the old (including personnel, production instruments, auxiliary tools such as cold protection, antifreeze and windproof). During the construction of pipeline optical (electric) cables in urban areas and towns, it is required that safety signs should be placed at each wellhead, and people should be kept to watch over the traffic. When the length of single optical (electric) cable is long, more migrant workers are needed for manual laying. During the construction of various complex pavements, strict organization and close cooperation must be made, and good communication tools (such as radios and speakers) should be equipped to make the actions of construction personnel coordinated, so as to ensure personal safety and light. Paint, in the road construction, as far as possible to set up safety signs and slogans, the signs are connected in series with reflective tape, and fog lights are needed to warn the urban construction at night, and personnel are arranged to cooperate with the traffic department to divert traffic; Right, before welding steel pipes, trial welding shall be carried out, and formal welding can be carried out only after the trial welding is qualified. When butt welding steel pipes, in order to prevent the excessive temperature difference from affecting the welding quality, protective measures should be taken for the welded joints, which should be covered with appropriate articles when it snows, and the joints that are not cooled after welding are strictly forbidden to touch the snow and ice; 9, strengthen the construction quality monitoring, joint can not have transverse cracks, when there is a joint does not meet the requirements, to deal with this batch of joint inspection, reject the unqualified products, after welding, the second acceptance, welding in the wind structure construction, when the temperature is lower than-2 degrees Celsius, no longer continue the construction. Fourth, prevent traffic accidents 1. Strengthen the maintenance of engineering vehicles to prevent accidents caused by vehicle failures; Second, it is strictly forbidden to drink and drive, drive without a license, and drive fatigue; Three, in case of severe snow and ice weather, vehicles should keep driving distance, to prevent the occurrence of tail chase accidents.

The dimensions of ventilation funnels are not less than 5cm in length, 3 cm in lower mouth width and 5cm in upper mouth width, and each dormitory shall be equipped with at least three ventilation funnels. 2. bank up is designated by special personnel before the lights are turned off every day. Exposure to coal-fired heating facilities is strictly prohibited, and the furnace plate and furnace cover should be fastened tightly; If the furnace plate and furnace cover can't be completely fastened tightly, it should be plastered with loess mud to prevent gas leakage.

3. Installation of smoke exhaust pipes for heating facilities. The socket of each pipe should be installed in the direction of medium circulation, and the interface should be sealed with adhesive tape; The smoke exhaust pipe outlet shall not be less than 5cm out of the eaves, the vertical pipe shall not be less than 2. m, and the horizontal pipe shall not be less than 5cm away from the ceiling of the building, and its direction shall not be toward the northeast of the winter monsoon. 4. Flammable articles such as clothes shall not be dried on the smoke exhaust pipeline, and flammable, explosive and volatile toxic substances shall not be piled up near the heating facilities.

5. The unburned coal cleared in bank up should be cleared out of the room and extinguished with clean water. Lu. Conduct safety education to prevent burns, gas poisoning and other incidents, and conduct medical rescue and emergency treatment education in China.

Paint. It is forbidden to connect heating facilities such as electric blankets and electric stoves in dormitories, offices and warehouses; Iodine tungsten lamp is not allowed to be used for indoor and on-site heating.

5. What should I do when I need to use a mobile ladder when working at heights?

It should be: ① Before using it, I should conduct an inspection, and in peacetime, there should be a special person responsible for the management, maintenance and repair.

② Before using the ladder, it must be placed firmly, with an angle of 6 with the ground? 7 degrees is appropriate, and the top end of the ladder should be firmly connected with buildings and structures. (3) when using the ladder on the wooden floor, the ladder angle should have a metal anti-skid device; When it is used on the hard and smooth ground surface of concrete, the ladder corner should be covered with rubber to form a fiber-dimensional anti-sliding pad, and it should be supported by a special person when necessary.

④ It is strictly forbidden for two people to stand on the same single ladder at the same time to work. Workers are not allowed to stand at the top of the ladder, and the distance from the top should be no less than four steps when using the leaning ladder, and no less than two steps when using the herringbone ladder. The leaning ladder and herringbone ladder should be fixed by ropes, and the fixed connecting ropes should be checked for conformity before construction, and other goods such as electric wires should not be used instead.

⑤ it is strictly forbidden to move the ladder when there are people on it. ⑥ When the rotating machine is attached to the ladder, a temporary protective barrier should be set between the ladder and the rotating part of the machine.
