Main piece size

There are no insulated ladders for climbing operations; or they do not meet safety requirements and are non-slip; and there are no dedicated people to watch and help you go up and down. Observe visually and take photos for documentation

Smoking while working in communication buildings, computer rooms, warehouses and other workplaces. Observe visually and take photos for documentation

Where open flames or electric welding operations are required, the fire operation approval procedures for the machine room have not been completed in advance and a "fire permit" has not been obtained; fire operations are not carried out under the supervision of dedicated personnel and equipped with fire-fighting equipment. Check the fire approval and fire-fighting equipment, and take photos for documentation

When entering the suspended ceiling or tunnel construction, the suspended ceiling and tunnel facilities were not checked for leakage, and insulating gloves and shoes were not worn. Use an electric pen to inspect the work area, make visual observations, and take photos for documentation.

Before the tower was installed, the tower base concrete was not tested to see if it had reached the design strength. Measure with rebound hammer and take photos for documentation

Tower installation workers and tower team electricians and welders must wear corresponding labor protection supplies in accordance with national labor insurance regulations, including safety belts, safety helmets, insulating shoes and necessary work clothes. Observe visually and take photos for documentation

Lifting equipment (truck crane, electric winch, manual winch, etc.) is not regularly maintained and accompanied by records of equipment maintenance; entering the construction site for installation and installation without starting up the machine for trial operation and inspection. On-site inspection and maintenance records; visual observation, taking photos and keeping records

The circumferential range with the tower base as the center and 1.05 times the tower height as the radius is the tower installation construction area. The site should be surrounded and warned. Non-construction personnel are not allowed to enter without approval (safety helmets should also be worn when entering with approval) ; The circumferential range with the tower base as the center and 20% of the tower height as the radius is the construction restricted area. During construction, no one is allowed to enter without the consent of the on-site commander and before notifying the personnel on the tower to suspend operations. Visual observation, rangefinder measurement, taking photos for documentation

When the tower feet are installed first using the segmented tower installation plan, the tower segments are installed without adjusting the level and height of the base plates of each tower foot to be consistent; the deviations such as the center verticality and tower body cross-sectional size are not adjusted and meet the specification requirements; the tower legs are not tightened After all the anchor bolts (according to the design quantity, anchor nuts must be installed), continue to assemble the upper tower section. Level, theodolite and torque wrench measurements, visual observation, taking photos for documentation

Installation of lattice iron towers and diagonal support poles without simultaneous support and protection in accordance with construction specifications. Observe visually and take photos for documentation

When erecting the cable tower, the construction workers went up to the tower to work before the cables were fixed. Observe visually and take photos for documentation

When installing an iron tower on the roof of a building, if the roof area does not meet the safe construction area, a protective net is not built on the outer wall, safety warning signs are set up in appropriate areas downstairs, and people are sent to direct passers-by. Observe visually and take photos for documentation

When working at height, do not keep the distance from strong electricity or strong magnetism at least 3 meters. Measure with a rangefinder or tape measure, observe visually, and take photos for documentation

Construction work on the tower is required when encountering the following climatic and environmental conditions: 1. When the ground temperature exceeds 40℃ or below -20℃; 2. Winds of level 5 and above; 3. Dust, clouds or low visibility; 4. Rain and snow Weather; 5. There is ice on the tower, and the frost and snow have not yet melted; 6. There are thunderstorms in nearby areas. Weather forecast, visual observation, on-site judgment, and taking photos for documentation

People who were sick and unfit to go up the tower after a doctor's examination reluctantly went up to the tower to work. People who have been drinking the day before or on the day go to the tower to work. Feedback from on-site personnel, visual observation, and taking photos for documentation

Before the transformation, the original base station environment was not familiar with and the construction was carried out blindly without knowing the on-site environmental conditions. Observe visually and take photos for documentation

There is no load review on the original tower, which will damage the performance of the original tower and equipment. Verify the design plan, inspect the damage, and take photos for documentation

After manually digging the soil to form the hole, no concrete retaining wall was installed according to the specifications or design requirements. Observe visually and take photos for documentation

The depth of excavated trenches, pits, and ditches exceeds 1.5m, and no grading or reliable support is provided according to the soil quality and depth. Visual observation, measurement with a rangefinder or tape measure, and taking photos for documentation

The depth of the manually dug pile hole exceeds 3 meters, and the digging personnel enter the hole without ventilation; when the depth of the pile hole is greater than 10m, there is no equipment specially equipped to supply air to the underground; in the event of heavy rain, the operation is not stopped. Visual observation, measurement with a rangefinder or tape measure, and taking photos for documentation

The operating surface of the foundation pit is too small and the safe working distance is not enough, which may easily cause safety accidents caused by objects striking. Visual observation, measurement with a rangefinder or tape measure, and taking photos for documentation

Failure to carefully observe the terrain and surrounding environment before erecting cement power poles, failure to properly equip working tools and workers according to the materials, specifications and weight of the poles to be erected, failure to clearly define the division of labor, and assign dedicated personnel to direct; when carrying electricity to paddy fields and hillsides The route was not selected in advance during the pole operation.

Before climbing the pole, you did not carefully check whether the pole root was in danger of breaking or falling over. You found that the pole was rotten, seriously cracked, or unstable, and you climbed the pole before it was reinforced.

Severe weather such as strong winds above Level 5, thunderstorms, ice and snow, dense fog, and insufficient lighting in the workplace are objective risk factors that directly cause falls from heights. It is not appropriate to use the pole for high-altitude operations or work at night.

When working under or near power lines, workers and equipment are not strictly prohibited from contacting power lines. When setting up wires, installing cables, etc. near high-voltage lines, the minimum clearance distance from high-voltage lines is: 2.5m below 35KV; 4m above 35KV.

There are no insulated ladders for climbing operations; or they do not meet safety requirements and are non-slip; and there are no dedicated people to watch and help you go up and down.

If the transformer is not kept at a safe height or has no protective measures, it is usually required that the distance between the bench type and the ground should not be less than 2.5 meters, and the ground-type guardrail (or wall) should not be less than 2 meters; there should be no transformer within two meters around the tower.

Cables were erected under high-voltage power lines, and no protective device was installed between the high-voltage lines and the cable intersection to prevent the cables from bouncing up and touching the high-voltage power lines when laying or tightening the cables.

During live work, the wiring is not standardized, and when the power is cut off, there is no dedicated person to watch the power supply end.
