Personal safety equipment maintenance and inspection

Personal safety protection equipment used by on-site construction personnel generally includes: safety helmets, safety belts, protective clothing, protective glasses, protective shoes, and gloves. These safety articles need to be properly used and worn, as well as simple maintenance, maintenance, and inspection knowledge.

The use and inspection of commonly used security products is very important to ensure the safety of construction personnel during the labor process. Because it is commonly used, people often disregard it, and it is easy to ignore its role. In particular, strict requirements for use are not kept in mind, and it is easy to cause vicious accidents.

Years of practice have proven that the commonly used safety helmets, seat belts, and safety nets play an important role in protecting workers' safety in the labor process. Especially in the high, cross and overlapping operations of power transmission and distribution construction, its magical effects are further exerted.

In order to give full play to the positive role of personal protective equipment in safety construction, it is necessary for all construction personnel to use it more standardly and correctly. It is necessary to manage and inspect commonly used safety protective equipment.

First, the helmet

On the power construction site, the helmets worn by construction workers are mainly to protect the head from harm. It can protect people's head from injury or reduce the degree of head injury in the following situations.
(1) When a flying or falling object hits the head;
(2) When the operator falls from a height of 2m or more;
(3) When there is a possibility of electric shock on the head;
(4) When walking or working in a low position, the head may collide with a sharp, hard object.

Safety helmets must be worn in accordance with standards, and use must comply with regulations. If it is worn and used incorrectly, it will not provide sufficient protection. Generally should pay attention to the following matters:
(1) Before wearing the helmet, adjust the rear cap adjustment belt to the proper position according to your own head type, and then fasten the elastic strap inside the cap. The elastic strap of the cushioning pad is adjusted. The vertical distance between the top of the head and the top of the cap body is generally between 20 and 50 mm, and at least not less than 32 mm. In this way, it can be ensured that when the impact is applied, the cap body has enough space for cushioning, and it is usually beneficial to the ventilation between the head and the cap body.
(2) Do not wear a hard hat or wear a brim behind your head. Otherwise, the protective effect of the helmet on the impact will be reduced.
(3) The mandible strap of the helmet must be buckled under the jaw and fastened tightly. This will not be blown off by strong winds, or it will be touched by other obstacles, or the helmet will come off due to the back and forth swing of the head.
(4) On the top of the helmet body, a cap liner is installed inside the cap body, and some holes are ventilated. However, do not casually open the hole for ventilation during use. This will reduce the strength of the cap.
(5) Due to the safety helmet being used, it will gradually be damaged. Therefore, it is necessary to check regularly to check for cracks, dents, cracks, and wear. If abnormalities are to be replaced immediately, they should be scrapped.
(6) It is forbidden to use a safety helmet with only the lower jaw attached to the cap shell, ie a helmet with no buffer layer inside the cap.
(7) The construction personnel shall not take off the helmet, place it aside, or use it as a cushion during the on-site operation.
(8) As the safety helmet is mostly made of high-density low-pressure polyethylene material, it has the properties of hardening and blemishes. So it is not easy to expose to sunlight.
(9) Newly-collared helmets first check whether there is a labor department's permission for production and product certification, and then see if there is any damage, uneven thickness, and whether the buffer layer, adjustment belt, and elastic belt are complete and effective. Does not meet the requirements of the immediate exchange.
(10) Safety helmets are also required for on-site indoor work. In particular, live helmets must be worn in the room, but helmets must be worn carefully because the helmets can not only collide but also provide insulation.
(11) Peacetime helmets should be kept clean and tidy, and they must not touch the fire source. Do not apply paint on the helmet. Do not sit on a stool to prevent loss. If lost or damaged, it must be replaced or replaced immediately. No helmets are allowed to enter the construction site.

Second, the seat belt

Electric power construction site, high work, overlap and crossover operations are numerous. In order to prevent the operator from falling down at a certain height and position, the operator must fasten the seat belt when he is working at a height or height. The use and maintenance of seat belts have the following requirements:
(1) The role of seat belts must be emphasized in thinking. Numerous cases have demonstrated that seat belts are "life-saving belts." However, there are a few people who have trouble wearing seat belts. It is inconvenient to walk up and down, especially some small living and temporary activities. They think that “there is a time to live with a safety belt”. As everyone knows, the accident occurred in a moment, so high-level operations must be required to fasten the seat belt.
(2)Before using the seatbelt, check that the rope is not deteriorating, if there is crack in the snap ring, and whether the circlip is good or not.
(3) In high places such as seat belts, there shall be no fixed hangers, and appropriate strength wire ropes or other methods shall be used. It is forbidden to hang the belt on a moving or sharp corner or loose object.
(4) high hanging low use. Hanging a seat belt high, people working underneath is called high hanging. This is a relatively safe and scientific method of hanging. It can reduce the actual impact distance when a crash occurs. In contrast with the low hanging high. It is the safety belt hanging in the low place and the person working on it. This is a very unsafe tying method, because when the fall occurs, the actual impact distance will increase, and both the person and the rope will be subject to a greater impact load. Therefore, the safety belt must be used in the same way as it is to keep it low.
(5) The seat belt must be hung on a firm member or object. To prevent swing or collision, the rope must not be knotted and the hook should be hung on the connecting ring.
(6) The seat belt rope protection sleeve should be kept intact to prevent the rope from wearing out. If it is found that the protective sleeve is damaged or peeled off, it must be used after adding a new one.
(7) It is strictly prohibited to use the seat belt without authorization. If a long rope with a length of 3m or more is used, a buffer must be added and all parts must not be removed.
(8) Before using the seat belt, check whether all parts are intact. Safety belts should be maintained and kept after use. Always inspect the seat belt sewing section and the hook section, and check the rifling thread for cracks and damage.
(9) When the seat belt is not in use, it should be properly kept. Do not touch high temperature, open flame, strong acid, strong alkali or sharp objects, and do not store it in a damp warehouse.
(10) The seat belts shall be tested once after two years of use. Frequent use shall be subject to visual inspections. Any abnormalities must be replaced immediately. Regularly or sampling the used seat belts and continue to use them as soon as possible.

Third, protective clothing

Electric power construction workers on the construction site should wear work clothes. Protective clothing has the following types:
(1) Overall protective overalls;
(2) Antivirus uniforms;
(3) Acid resistant work clothes;
(4) Fireproof work clothes;
(5) Insulation work clothes;
(6) ventilation cooling work clothes;
(7) Water cooling working clothes;
(8) Anti-radiation work clothes;
(9) Labor protection raincoats;
(10) Ordinary work clothes.
The wearing requirements of protective clothing for workers on construction sites are:
(1) Workers must wear overalls while working;
(2) The cuff must be tight when operating the rotating machine;
(3) Personnel engaged in special operations must wear protective work clothes;
(4)Welder uniforms should be made of white canvas.

Fourth, protective shoes

There are many kinds of protective shoes, such as leather safety shoes, anti-static rubber sole shoes, plastic anti-smashing safety shoes, insulated leather shoes, low-voltage insulating rubber shoes, acid and alkali-resistant shoes, acid and alkali plastic molded boots, high-temperature protective shoes, and thorn-proof. Empty shoes, welding protective shoes and so on. Should be based on the different choices and use of the workplace and content.

Power construction construction commonly used insulation boots (shoes), welding protective shoes, acid-resistant rubber boots and leather safety shoes. The requirements for insulating shoes are:
(1) Must be used within the specified voltage range;
(2) The rubber parts of the insulating shoes (boots) are not damaged, and a preventive test is made every six months;
(3) It shall not be used as an auxiliary safety device under conditions such as flooding, oleic acid, and alkali.

Fifth, protective gloves

Most of the work on the construction site is done by both hands, which determines that the hands are often in danger. The safety of the opponent mainly depends on gloves.

When using protective gloves, after analyzing the parts, equipment, and work conditions, select suitable materials and gloves that are easy to operate to protect the work. In the case of operations requiring fine adjustment, wearing protective gloves is inconvenient to operate, especially for operators who use drilling machines, milling machines, and conveyors and where there is a risk of crushing. If gloves are used, they are mechanically entangled. danger. Therefore, personnel engaged in these operations are strictly prohibited from using protective gloves.

The following are the commonly used protective gloves on electric power construction sites:
(1) Labor protection gloves. With the function of protecting hands and arms, workers usually use such gloves when working.
(2) Insulating gloves for live working. According to the voltage to select the appropriate gloves, check the surface for cracks, cracks, sticky, brittle and other defects, if abnormal use is prohibited.
(3) Acid and alkali resistant gloves. Primarily used for gloves when in contact with alkali.
(4) Rubber tension gloves. Mainly used for contact with mineral oil, vegetable oils and fat clusters.
(5) Welder's gloves. For the protective gloves worn in the electric and fire welding industry, check the surface of the leather or canvas for incomplete phenomena such as stiffness, thin files, and holes, and if any, use them. The gloves should be of sufficient length and the wrists should not be exposed outside.

Sixth, common safety protective equipment inspection method

The commonly used safety protective gear must be carefully checked and tested. Is there any debris on the safety net, whether it is damaged by objects or damaged by lifting objects? After the hitting of the helmet, there is a crack or the like. Safety checks are often carried out as required.
(1) Hard hat: 3Kg heavy steel ball, vertical impact from 5m height is not damaged. The test should use wood to make a half-head model, and tie the buffer elastic band in the helmet of the experiment on the model. Safety helmet tests made of various materials can use this method. The inspection cycle is once a year.
(2) Seat belt: According to the national regulations, the factory test is to take an object with a load of 120kg. The seat belt is impacted from the 2-208m elevated frame. All parts are qualified without damage.

According to the actual situation, the construction unit can take some feasible measures according to local conditions under the conditions of meeting the test load standard. Some of the methods often used by construction agencies are: use sacks, wood shavings, etc. as fillers, and then add iron to achieve the experimental load standard. With a shelf that specializes in experiments, dynamic and static load tests are performed.

Nylon seat belt accessories, the ultimate tensile index is: belt 1200-1500kg, was taken with 700-1000kg, safety rope 1500kg, hook ring 1200kg, fixed card 60kg, legs with 700kg.

The load test requirements for seat belts are as follows: The construction unit shall carry out a static load test on the seat belts periodically. The test load shall be 225 kg, and shall be hung for 5 min. Check for any deformation, cracking, etc., and make a record.

The inspection period of the seat belt is: Before each use of the seat belt, it must be carefully checked. Two years after the use of seat belts, spot checks were conducted and the old seat belts were tested every six months.

It should be noted that any safety gear that has been tested must not be reused.
(3) The inspection of personal protective equipment must also pay attention to:
1) Whether the product has a product produced by a "production license" unit;
2) Whether the product has a "product certificate";
3) whether the product meets the relevant quality requirements of the product;
4) The product specifications and technical performance are in line with the protection requirements of the operation.
General requirements for the use, maintenance, and inspection of personal protective equipment mentioned above are to be carefully studied by all personnel of the team and the team. The focus is on the three items of safety helmets, seat belts, and protective shoes. The company will organize examination results in the company's evaluation meeting. .
