What does Wu Linbian mean?

"Wulinbian" must install a double-layer fence of more than 1.0M or set up a safety net. The specific safety control points are as follows:

(1) The edges of deep foundations, stairwells, roofs, light wells, transfer platforms, balconies, both sides of pedestrian passages, and both sides of unloading platforms The sides must be protected by two steel pipes, and red and white marks must be painted on the steel pipes.

(2) Two protective railings must be erected on the outside of the temporary frame used to tie steel side beams and columns.

(3) Protective doors must be installed on the sides of the tic-tac-toe hoist and the unloading platform of the passenger and cargo elevator. The protective door must be a switch door welded with steel bars. Curved steel bars are not allowed to be used as protective doors.

(4) When working near the edge, safety warning signs must be set up.

(5) When the outside of the edge work is close to the street, in addition to setting up protective barriers, toe boards, and sealing safety nets, hard sealing measures such as wattle fences should also be taken on the facade to prevent falls during construction. Things hurt people.

"Three Treasures" Protection

You must wear a safety helmet when entering the construction site, and wear a safety belt when working at heights. There should be a sign saying "You must wear a safety helmet when entering the construction site" at the entrance and exit gates of the site. Construction workers call hard hats, seat belts, and safety nets the "three treasures" that save their lives.

(1) Safety helmet

1. Safety helmet requirements: There should be manufacturer name, trademark, model, production date, license number, industrial production license number, safety production License number, factory inspection certificate, test report, each helmet has batch verification by the inspection department and factory inspection certificate and approval certificate.

2. Impact resistance: After the helmet is treated at temperatures of +50°C, -10°C, or immersed in water, then lift a 5kg steel hammer from a height of 1m. When falling freely and impacting a helmet, the maximum impact force should not exceed 500kg (5000N or 5kN), because the human cervical spine can only withstand an impact of 500kg and will be vulnerable to injury if it exceeds.

3. Penetration resistance. According to the different materials of the helmet, it can be treated by three methods: +50℃, -10℃ or water immersion. Use a 3kg steel cone to drop freely from a height of 1m above the helmet. The steel cone will penetrate safely. cap, but not touching the scalp. This requires that when the selected safety helmet is worn, the horizontal distance between the top of the hat lining and each side of the inner surface of the hat shell should be maintained at 5 to 20 mm.

4. Good low temperature resistance. When the temperature is below -10℃, the impact resistance and penetration resistance of the helmet do not change.

5. The lateral rigidity can meet the specification requirements.

6. Safety helmets should be used correctly, worn properly, and fastened. The chin strap must be buckled under the chin. It is not allowed to litter or litter, it is used for sitting and cushioning, and helmets with missing linings, missing straps or damaged ones are not allowed to be used.

(2) Seat belts

1. Seat belt requirements: The length of the safety rope used by erect workers should be 1.5~2m, and a permanent trademark should be sewn on the body of the seat belt. , certificate, inspection certificate. The certificate should indicate: product name, year and month of production, tensile test, impact test, manufacturer name, inspector name. When the safety belt enters the site, there should be quality certificates, test reports, production licenses and other quality certification documents.

2. Seat belts should be hung high and used low to prevent swings and collisions; various parts of the seat belts must not be removed at will.

3. After the safety belt has been used for two years, the user should select a certain proportion of the quantity according to the size of the purchased batch, conduct a random inspection, and use an 80kg sand bag to do a free fall test. If it does not break, it can Continue to use, but the randomly inspected sample belts should be replaced with new lanyards before they can be used; if the test fails, the purchased batch of safety belts should be scrapped.

4. Frequently check the appearance quality of the seat belt. If it is found to be mildewed, hard and brittle, broken, damaged or smelly, it should be replaced immediately.

5. Seat belts should be scrapped after 3 to 5 years of use.

6. Seat belts should be used correctly. Fasten the seat belt, hang and fasten the safety hook. The site must be equipped with safety belts that comply with national standards. During construction, high-altitude operations, climbing operations, and independent suspended operations, Operators should wear seat belts and hang them on a solid and reliable object when in use. After use, a designated person should be responsible for safekeeping.

(3) Safety net

1. Safety net requirements: The mesh density is not less than 2000 mesh/10cm*10cm, and there should be batch verification and factory inspection by the nationally designated supervision and inspection department. Certificate of conformity, test report and license.

2. Penetration test: Place the 1.8m*6m safety net at an angle of 30° with the ground, and straighten and fix the four sides. At a place 3m above the center of the net, use a 5kg steel pipe of Ф48*3.2 and drop it freely. If the net does not penetrate, it is qualified. If the net penetrates, it is unqualified.

3. Impact test: Place the dense-mesh safety net horizontally and tighten the four sides. At 1.5m above the center of the net, a 100kg sandbag falls freely. If the length of the edge of the net torn is less than 200mm, it is qualified.
