June this year is the 22nd national "Safety Production Month"
The theme is "Everyone speaks safety, everyone will respond"
Construction site safety common sense labor protection supplies use

First, safety helmet

Safety helmets must be worn at the construction site. The correct wearing of the helmet should pay attention to two points, one is that the hat lining and the hat shell can not be close, there should be a certain gap, the top gap is 20mm-50mm, and the circumference is 5mm - 20mm, when something falls on the helmet shell, the hat lining can play a cushioning role, protect the head and cervical spine, and the hat lining can not be taken off for use; The second is that the hat strap must be fastened to prevent the object from striking multiple times and causing accidents.
2. Seat Belt

To use qualified seat belts, pay attention to check the service life of the seat belts, the service life of the seat belts is 5 years. Height operators, when there is no safety protection measures, must fasten the safety belt, hang the first and then work, should be high and low use. Do not use the rope knot, nor do you allow the hook to be directly hung on the safety rope, should be hung on the connection ring for use.
3. Other protective equipment

Where directly engaged in live work, must wear insulation shoes, wear insulation gloves to prevent electric shock accidents. Electric welding workers engaged in electric welding operations must wear electric welding gloves, wear insulating shoes and use goggles and protective masks. Electric welding operations may produce arc. Wearing protective masks and protective gloves can prevent injuries.

Construction site safety instructions

First, the general code of conduct of construction personnel
(A) before entering the construction site must go through safety education. Everyone should have a full understanding of the day's work and possible safety risks.

When going up and down the stairs, you must use the special passageway, bridleway, and do not climb the shelves and temporary facilities.
(2) Requirements for material handling and tool use in high altitude operations.
The ladder must be solid and the feet must have anti-slip measures. The span of the scaffold working at a height shall not be greater than 2 meters, and no more than two people shall operate in each span (the load shall not exceed 150 kg). It is forbidden to disassemble the outer frame and close the net. If material needs to be transferred, it should be hung up in time after opening. When the template is dismantled at a height above 3 meters, a firm operating platform should be set up, and a guardrail should be set up at the edge. A horse stool is available below 3 meters. The tools of high operation should be put into the tool bag, the objects and waste materials removed should be cleaned and transported in time, and should not be piled and discarded anywhere. Do not throw when passing objects.
(3) Requirements for the use of protective equipment for high altitude operation
Height workers must wear safety belts when there is no safety protection. The reserved hole must be equipped with a strong cover plate, protective railing, safety net or other protective measures against falling. Effective protective railings or fixed gates must be set up at the elevator wellhead, and removal or climbing is strictly prohibited. Step or climb ladder must be set up not less than 1 meter high protective railing.

High-altitude construction: safety rope is life rope

The safety rope is the "life rope" when working at altitude, which plays a safety protection role for the staff.
The safety rope is one of the important protective equipment used to protect the personal safety of high altitude and high altitude workers, and the correct use of safety rope is one of the important measures to prevent the on-site high altitude workers from falling casualties and ensure personal safety.

1, the correct use of safety rope
(1) One end of the escape rope or escape ladder is fixed on a firm object, the other end is hung on the safety belt or wrapped around the waist, tie the safety hook, and throw the life rope down the window to the downstairs;
(2) Put on protective gloves and hold the life rope belt with both hands, hook the left foot on the windowsill, push off the outer wall with the left foot, and move the left foot out of the window after treating people smoothly;
(3) The legs are slightly bent, the feet are pushing hard against the wall at the same time, the arms are straight, the hands are slightly loose, the eyes are staring down, and the life rope is sliding down;
(4) When approaching the ground, bend the right arm forward, bend the two legs of the tightening rope, and land on the toes first.
2, the use of safety rope precautions

(1) It is strictly prohibited to use hemp rope as a safety rope;
(2) If the length of the safety rope exceeds three meters, it is necessary to install a buffer to ensure the safety of high-altitude workers;
(3) Two people cannot use a safety rope at the same time;
(4) In high-risk operations, in order to make high-altitude workers safer in the movement, while fastening the safety belt, they should be hung on the safety rope.
