Each site operator must properly use safety nets, safety helmets, safety belts, safety shoes, welding eyepieces, face masks, and other safety items in accordance with relevant safety regulations and the specific requirements of each type of work.
(a) Safety net
1. The safety net should have special personnel responsible for purchasing, keeping, issuing and storing. When the net body is in storage and inventory, it is necessary to check the statutory permanent signs attached to two different locations on the Internet. Above the signage are marked product markings, material specifications and side lengths, manufacturer name, manufacturing lot number, serial number and date, dry and wet wire rope breaking strength, load height, expiration date and license number. It is forbidden to purchase or use safety nets without product specifications and quality inspection certificates.

2. In the process of use, special personnel should be assigned to maintain the safety net, and timely inspection and maintenance. Falling objects in the net should be cleaned regularly to keep the net clean. Also avoid massive welding or other Mars falling into the net and avoid high temperatures or steam conditions. When the net body is contaminated with chemicals or the mesh rope is embedded in coarse sand particles or other foreign materials that may cause abrasion, it must be cleaned and washed to make it dry naturally.

3. The nets removed after use must be specially inspected and signed by qualified personnel before they can be placed in stock or reused.

4. Once the safety net has been set up, it must be checked by full-time personnel and it can be formally put into effect after it is deemed qualified. According to the net, support frame and connector for inspection. The inspection of the network first pays attention to whether the type meets the requirements for use, whether the network is equipped with a product quality inspection certificate and whether the appearance of the network is subject to disease. Then check the accuracy of each joint location, whether the spacing is reasonable and no loose phenomenon. Also pay attention to whether the working environment has no corrosion and damage to the net. The support frame must have sufficient strength, rigidity and stability, the appearance is neat without damage, and the tether tie has no support angle or sharp edge lashing points in line with regulations. The connections of the connectors should be firm and secure. The lashing points of the tether and the support frame should not be loosened after being subjected to the force, and the spacing and number of points are in compliance with the regulations. Wire rope specifications and quality meet the requirements of use.

5. Do a check every two weeks or one month in the construction process. When a safety net receives a large impact, such as a human body or an object equivalent to a human body, it must be checked in time and the inspection is divided into the above three parts. The inspections of the network include: no construction waste can be stored in the net, and no articles can be accumulated under the net. The net body must not be seriously deformed and worn, and whether it is contaminated by chemicals, acid and alkali fumes, and burning sparks. The support frame must not be severely deformed and worn, and there must be no loosening of the joints. The connection point between the net and the net and between the net and the support frame is also not allowed to loosen. All bolted snails cannot be severely worn or deformed. After the inspection of the safety net, all unqualified items and parts must be refurbished or replaced, and only after they meet the requirements of relevant regulations can they be put into use. As the construction period is often longer, it is necessary to carry out a strong test of the test rope according to the batch number every three months during the construction period and make a good record of the test. A sample impact test is also required once a year.

6. The service life of the safety net Because of the large differences in the conditions of use and habits between the regions and the construction units, the influencing factors, and the frequent accidents during use, it is difficult to make clear regulations. In order to prevent the use of safety nets with degraded performance, it is dangerous. Therefore, safety nets are required to be tested periodically to determine whether they can continue to be used.

7. Do not use iron hooks or spiked tools in the safety net to prevent damage to the net. The nets should be stored in a warehouse or a special place, and be classified, stored on shelves in batches, and not allowed to be randomly stacked. The warehouse requires ventilation, shading, heat insulation, moisture proof, and avoidance of chemical corrosion. In the process of storage, it is also required to regularly inspect the nets, find problems, and handle them immediately to ensure safety.
(B) Hard Hat
1. All personnel entering the construction site must wear a safety helmet. The helmet must not be removed from operation, set aside, or used as a cushion.

2. The current helmet must comply with the national standard GB-2811 "safety helmet" provisions, in addition, the helmet should also have the advantages of light weight, good air permeability.

3. The national standard specifies that the height of the helmet to be worn is from 80 to 90 mm in vertical distance from the bottom edge of the hoop to the top of the head (represented by the wooden head model during the test). Its size is divided into large, medium and small three, can be selected according to need. National standards for the helmet is the most important requirement is able to withstand the impact of 5000N. That is, at the instant when the falling object impacts the helmet, the helmet is not damaged when the impact force is 5000 N. The impact force is not only greatly reduced but also transmitted from the landing point to the human head through the joint points of the cap liner. The person's head can withstand and is not harmed. Plastic safety helmets can meet these requirements better.

4. To use the helmet properly, buckle the cap and adjust the spacing of the cap (usually about 4 ~ 5cm), do not easily loosen or shake. The lack of lining or broken safety helmet shall not be used.

5. When purchasing helmets, you must check whether there is a product inspection certificate and do not allow the purchase and use of nonconforming products.
(three) seat belts
1. Seat belts should meet the requirements of the national standard GB6095-80 "safety belt" requirements of the seat belt structure, materials, technical performance and use of storage requirements.

2. Use high hanging low to prevent swinging collision, the rope can not be knotted, the hook should be hung on the connecting ring. When there is an abnormality, replace it immediately and add a new one when replacing the new one. Use buffers for long ropes longer than 3m.

3. In climbing and vacant operations, it is necessary to wear a seat belt and have a reliable hooking facility. It is forbidden to wear a seat belt only at the waist and not to hook the hook ring at a fixed facility.

4. The seat belt should be properly kept when not in use, and it must not be exposed to high temperature, open flame, strong acid, strong alkali or sharp objects. Frequently used ropes should always be visually inspected; sampling should be done after two years of use, and sampled belts should be replaced with new ones. The inspection of seat belts shall be carried out in accordance with GB6096-85 "Safety belt inspection methods". Do not purchase and use unqualified products.
