1, where the fall height of the reference plane 2 meters (including 2 meters), there is a possibility of falling from the height of the operation, known as work at height.
2, before working at height, must be carried out to analyze the danger point, the development of preventive measures. 3, before working at height, carefully check the safety protection facilities.
Such as checking the lifting gear is not safe and reliable, lifting machinery, braking, insurance and protection devices are not safe and reliable, found that the problem should be dealt with in a timely manner. 4, work at height should be set up safety fences and signs to stop the pedestrians, vehicles, to avoid falling objects.
5, when working at height, should always wear the helmet on the head, shall not be taken off. 6, when working at height, must use the safety belt, safety belt hooks or or rope should be hung on the strong and solid components or specialize in safety belts with the steel wire rope.
Stop hanging on the moving or unsound objects.
2. Working at height to pay attention to what safety matters
1, the hook or rope of the safety belt should be hung on a strong and solid components or wire rope designed for hanging the safety belt.
Prohibit hanging on the moving or unsound objects. 2, high work should always use the tool bag.
Larger tools should be tied to the rope in a solid component, not allowed to put, in order to prevent accidents from falling from a height. 3, in the work at height, in addition to the relevant personnel, do not allow others in the workplace below the line or stay, the workplace should be fenced or installed below other protective devices to prevent falling objects hurt.
If you work on the grille-type platform, in order to prevent the tools and equipment fall, should be paved with wooden planks. 4, tools and materials are not allowed to be thrown up and down, to be tied to the rope down or up to send, so as not to injure the staff below or destroy the scaffolding.
5, the upper and lower levels of work at the same time, the middle must be set up tight and solid protective partition, canopy or other isolation facilities, the staff must wear helmets.
3. What are the basic provisions of the safety measures for work at height
The basic provisions of the safety measures for work at height are as follows: (1) safety and technical measures for work at height and the required materials and equipment must be included in the project's construction design.
(2) unit project construction should be responsible for the project's safety and technology of work at height and the establishment of a corresponding responsibility system. Before the construction, should be carried out level by level safety technology education and briefing, the implementation of all safety technology measures and personal protective equipment, without the implementation of the construction shall not be carried out.
(3) safety signs, tools, instruments, electrical facilities and various equipment in the work at height must be checked before construction to confirm their integrity before being put into use. (4) Climbing and hanging work at height personnel and build safety facilities for work at height, must be qualified for professional technical training and professional examination, licensed to work, and must be .
Regular physical examination. (5) the construction of safety facilities for work at height, found defects and hidden danger, must be resolved in a timely manner; jeopardize personal safety, you must stop the operation.
(6) construction workplace objects that may fall, should be removed or fixed. The materials used in the high work should be stacked smoothly, so as not to hinder the passage and loading and unloading.
Tools should be put into the tool bag; work in the aisle, access panels and climbing gear, should be cleaned up at any time; dismantled objects and residual materials and waste should be cleaned up in a timely manner and transported away, and shall not be arbitrarily placed or thrown down. Passing objects are prohibited to throw.
(7) rainy days and snowy days for high work, must take reliable anti-skid, cold and frost measures. Where water, ice, frost, snow should be removed in a timely manner.
The towering buildings for high work, should be set up in advance to avoid lightning facilities. In the event of six or less strong winds, fog and other inclement weather, shall not be open-air climbing and overhead work.
After snowstorms and typhoons, the safety facilities for work at height should be checked one by one, and should be repaired and improved immediately if they are found to be loose, deformed, damaged or detached. (8) due to operational necessity, temporary removal or change of safety protection facilities, must be agreed by the construction manager, and take appropriate and reliable measures, the operation should be immediately restored.
(9) protective shed construction and demolition, should set up a warning area, and should be sent to specialists to monitor. It is strictly prohibited to dismantle the upper and lower at the same time.
(10) the main force of the safety facilities of work at height rod, mechanical calculations in accordance with the general structural mechanics formula, strength and deflection calculations in accordance with the current relevant norms, but the strength of the steel bending member of the calculation does not take into account the impact of plasticity, the structure should be in line with the current requirements of the corresponding norms.

4. Communications engineering work at height, the main prevention of which safety
First, the prevention of personal injury, fall prevention, anti-skidding accidents, a winter construction, to strengthen labor protection, construction workers with gloves, wear rubber-soled shoes, increase anti-skidding measures, it is strictly prohibited to wear hard-soled shoes.
Second, into the construction site must wear a helmet, cold hat can not replace the helmet; third, open-air work to match the cold supplies, construction on the shelf to be careful to prevent "probe board" stepping on the air, high-altitude work to suspend the safety belt, at a height of more than one.5 meters on the bench, to be operated by a person to guardianship; fourth, the height of the operating personnel must wear slip-resistant shoes, protective gloves, and increase slip measures, strictly prohibit wearing hard-soled shoes. Must wear non-slip shoes, protective gloves and other anti-slip, anti-freezing measures, must fasten the safety belt; 5, four or more gusts of wind prohibit the tower crane installation, jacking operations, land level gusts of wind prohibit lifting operations and work at height; land, in the negative temperature of binding, lifting steel components with steel cables and components in direct contact, should be set up non-slip spacer pads. Check the lifting wire rope has no damage, U-type card is locked, hook insurance is effective; paint, because of the winter material brittle, easy to slip, so lifting heavy tonnage of goods tools should be left with a greater safety factor to fully ensure safety; bar, encountered in the rain and snow and other inclement weather, we must promptly remove the construction site of the water, snow, rain and snow and gusty weather is strictly prohibited to force the organization of the construction.
Second, fire prevention, anti-poisoning accidents a, to prevent fire, fire facilities and equipment should be complete, intact and can be used, the engine room (base station) shall not be stacked flammable and explosive substances; second, the safety officer should be regularly on the construction site of the power supply, fire prevention inspections, to prevent communications, fire accidents and theft of the matter; third, it is strictly prohibited to move the open fire in the site to warm up, especially in the construction site, once found, will be heavily fined; fourth, in the lower people under the people's power, the fire will be the first time, the construction site, the fire will be the second time, the fire will be the second time. Heavy penalties; Fourth, in the manhole operation should be done before "a pass, a check": (a) in the manhole operation should be before and after the manhole operation area manhole cover open, the first to do the ventilation process. (B) check the manhole for poisonous and harmful gases, to ensure the safety of the well.
5, in the manhole operation must do "a wear, a look, two are not allowed, three prohibited": (a) the operator should wear a good helmet, wear waterproof pants and rubber boots. (B) outside the well (on) should be guarded.
