What are the main safety precautions when working at high altitudes in communication projects?

1. Prevent personal injury, fall and slip accidents 1. During winter construction, labor protection should be strengthened. Construction workers should wear gloves and rubber-soled shoes, and add anti-slip measures. Hard-soled shoes are strictly prohibited. 2. You must wear a safety helmet when entering the construction site. Cold-proof hats cannot replace safety helmets. 3. When working in the open air, you must be equipped with cold-proof supplies. When constructing on a rack, be careful to prevent the "probe board" from being stepped on. When working at heights, you must wear a safety belt. On horse stools with a height of more than 1.5 meters, one person must operate and the other shall supervise; 4. Personnel working at heights must wear non-slip shoes, protective gloves and other anti-slip and anti-freeze measures, and must fasten seat belts; 5. Tower crane installation is prohibited in strong winds above Level 4. Jacking operations, hoisting operations and high-altitude operations are prohibited in strong winds above land level; on land, when the steel ropes used for binding and lifting steel components in negative temperatures are in direct contact with the components, anti-slip spacers should be installed. Check whether the hoisting wire rope is damaged, whether the U-shaped clamp is locked, and whether the hook insurance is effective; Because the material is brittle and slippery in winter, tools for lifting heavy-tonnage cargo must have a greater safety factor to fully Ensure safety; When encountering bad weather such as rain or snow, the accumulated water and snow at the construction site must be removed in time. It is strictly forbidden to organize construction in rain, snow and windy weather. 2. Prevent fires and poisoning accidents 1. To prevent fires, fire-fighting facilities and equipment should be complete, intact and functional, and flammable and explosive items should not be piled in the computer room (base station); 2. Safety officers should regularly inspect the construction site Check the power supply and fire protection to prevent communication, fire accidents and theft; 3. It is strictly prohibited to use open fires for heating at the construction site, especially at the construction site. Once discovered, heavy fines will be imposed; 4. Before going down to the manhole for work, "one pass, one pass, "First inspection": (1) Before manhole operations, the front and rear manhole covers of the working area should be opened and ventilated first. (2) Check whether there are poisonous and harmful gases in the manhole to ensure safety in the well. 5. When working in manholes, "one thing to wear, one thing to look at, two things not allowed, and three things forbidden": (1) Operators should wear safety helmets, waterproof pants and rubber boots. (2) There should be dedicated personnel guarding the outside (top) of the well. (3) It is not allowed to light a blowtorch in the well; it is not allowed to smoke in the well. (4) Non-operators are prohibited from watching; it is prohibited to bring flammable materials in the manhole; it is strictly prohibited to use flammable materials to clean the cables (gasoline, alcohol, toluene, etc.).

3. Preventing Cyber ??Security Accidents in China 1. It is strictly prohibited to use high-heat lamps (such as sun lamps, etc.) for temporary lighting during construction in the computer room, and it is strictly prohibited to use non-construction electric heating appliances such as electric water heaters and electric furnaces; 2. The construction temperature is low in winter, and construction workers' joints are not Flexibility, a lot of clothing, and inconvenient movement. When installing equipment and deploying cables, attention should be paid to the safety of the equipment and the site to prevent interruption of the site's business due to construction; 5. Cutting, relocation, or dismantling of optical (electrical) cables Before switching over, relocating or demolishing old buildings, detailed plans and procedures must be formulated, a thorough analysis must be conducted, on-site resources must be carefully surveyed and the data on switching, relocation or demolition must be verified. After the plan, steps and methods (including personnel, production equipment, cold protection, anti-freeze, wind protection and other auxiliary tools) are determined and approved, technicians (administrator or above) of each participating unit will verify the site again, and the maintenance supervisor will be stationed on site. Only under the command of technical personnel can they enter the site for implementation to avoid communication accidents such as cutover errors, business interruption or accidental disassembly; On land, when carrying out pipeline optical (electrical) cable construction in urban areas and towns, each wellhead is required to Safety signs must be placed and people must be on guard to pay attention to passing vehicles. When the length of a single optical (electrical) cable is long, more migrant workers are required for manual laying. During the construction of complex road surfaces, strict organization, close cooperation, and equipment must be Good communication tools (such as wireless walkie-talkies, speakers, etc.) enable construction workers to coordinate their movements and ensure personal safety and the safety of optical (electrical) cables; When constructing on the side of the highway, install as many production safety signs and slogans as possible, and mark the The signs are connected in series with reflective tapes. During nighttime construction in urban areas, fog lights are required to warn, and personnel are arranged to cooperate with the traffic department to ease traffic. Before welding bars and steel pipes, test welding should be carried out. Only after the test welding is passed can formal welding and butt welding be carried out. When welding steel pipes, in order to prevent the temperature difference from being too large and affecting the welding quality, protective measures should be taken for the welded joints. When it snows, they should be covered with appropriate items. Joints that have not been cooled after welding are strictly prohibited from touching ice and snow; 9. Strengthen construction quality monitoring, and joints should be There must be no transverse cracks. When a joint does not meet the requirements, the batch of joints should be inspected and unqualified products should be removed. After re-welding, a second acceptance inspection should be carried out. The welding should be carried out in a windshield structure. When the temperature is low When the temperature reaches -20 degrees Celsius, construction will no longer continue. 4. Preventing traffic safety accidents 1. Strengthen the maintenance and upkeep of engineering vehicles to prevent accidents caused by vehicle failures; 2. It is strictly prohibited to drive under the influence of alcohol, drive without a license, and drive while fatigued; 3. In the event of severe ice and snow weather, vehicles are moving Driving distance should be maintained to prevent rear-end collisions. 5. Heating and fire prevention in winter 1. The use of coal-fired heating in winter construction dormitories should prevent carbon monoxide poisoning of construction workers. The dormitories should ensure adequate ventilation conditions; each dormitory is equipped with a ventilation funnel according to the size of the room. The size of the ventilation funnel: length is not less than 50cm. The width of the lower opening should not be less than 30cm, and the width of the upper opening should not be less than 5cm. There should be at least three ventilation funnels in each room. 2. Designate a dedicated person to seal the fire before turning off the lights every day. Coal-fired heating facilities are strictly prohibited from being exposed. The stove plate and furnace cover should be tightly buckled. If the stove plate and furnace lid cannot be fully buckled and tightly covered, they should be plastered tightly with loess mud. To prevent gas leakage. 3. When installing the exhaust pipe of heating facilities, the socket of each pipe should be installed in the direction of medium circulation, and the interface should be sealed with tape; the outlet of the exhaust pipe should not be less than 50cm from the eaves, and the riser should not be less than 2.0m, horizontal The distance between the pipe and the roof of the house must not be less than 50cm, and its orientation must not face the northeast direction where the winter monsoon wind blows. 4. Clothes and other flammable items must not be dried on the smoke exhaust pipe, and flammable, explosive, or volatile toxic substances must not be piled near heating facilities. 5. The unburned coal removed when sealing the fire should be cleared out of the room, and the unburned coal should be extinguished with clean water. Lu. Carry out safety education to prevent incidents such as burns and gas poisoning, and provide education on medical rescue and emergency response to emergencies. Paint. It is strictly forbidden to connect electric blankets, electric stoves and other heating facilities in dormitories, offices and warehouses; it is also not allowed to use iodine tungsten lamps for heating indoors or on site
