Tips: Basic requirements for safety performance testing of labor protection articles

Basic requirements for the safety performance of labor protection products The company's safety and security departments must comply with regulations for expired safety helmets. After a spot check and test, they can be used continuously. After a random inspection every year, the safety helmets are scrapped.

First, the helmet

1. Composition: It consists of a cap shell, a cap liner, a lower jaw strap, and a rear hoop.

2. Storage: The helmet should not be stored in the acid, alkali, high temperature, sun, and humid places, and it should not be stored together with the hard objects.

3. Effective period: From the date of production, the plant weaves caps shall not exceed two years; plastic caps, paper caps and plastic caps shall not exceed two and a half years; and glass fibre reinforced plastic caps shall not exceed three years.

The company's safety and security departments must perform spot checks on the expired helmets in accordance with the regulations before they can continue to use them. After a year's sampling inspection fails once every year, the batch of safety helmets is scrapped.

4. Each top safety helmet shall have the following four permanent markings and be affixed with safety certifications: 1 name, brand, model of the manufacturer; 2 year and month of manufacture; 3 production certificate; 4 safety production license number.

5. Equipped with standards: Construction companies must provide a safety helmet for each type of work except construction site workers and construction site guards; renewal should not exceed 48 months but should be checked according to the effective period of safety helmets and inspections conducted by the company's safety and security departments. If it fails, it can be replaced in advance.

6. Sampling test sample quantity: 12 types of Y class.

Second, the seat belt

1. Composition: Consists of straps, ropes and metal fittings.

2. Storage: Seat belts should be stored in dry, ventilated warehouses. Exposure to high temperatures, open flames, strong acids, and sharp, hard objects must not be allowed.

3. Use period: After using the seatbelt for two years, check the batch purchase situation once; if using frequent ropes, you must always perform a visual inspection to find abnormalities. Replace the new rope immediately; use the belt for a period of 3 to 5 years and find abnormalities. Should be scrapped in advance.

4. Marks: (1) Metal fittings shall be marked with the manufacturer's code; (2) The permanent belt mark, certificate, safety production license number and safety appraisal shall be sewn on the seat belt body; (3) The certificate shall indicate: The name of the production year and month tensile test 4412.7N (450kgf impact weight 100kg manufacturer name inspector's name; 5 each seatbelt is carried in a plastic bag with printed on: Product name Production year Static load 4412.7N (450kgf) Impact weight 100kg manufacturer's name and use precautions.

5. Equipped with standards: The personnel of construction and construction enterprises engaged in working at heights such as poles, suspensions, and climbing should be equipped with a safety belt for each person. The replacement may be based on the life of the seatbelt and the frequent use.

6. The number of samples to be sampled: 3 for each model, 3 for metal parts, and 3 for rope samples.

Third, safety net

1. Classification: Including flat nets, vertical nets, and dense-mesh security nets, represented by letters P, L, and ML, respectively.

2. Composition: It is composed of net body, side rope, tether and other components.

3. Concentric safety nets The mesh density is not less than 800 meshes/100cm2. It is generally composed of a mesh body, eye-opening buckles, side ropes and additional tethers.

4. Storage: The safety net should be kept by special personnel and temporarily stored in warehouses or special places where there is no need for ventilation, light, heat, or chemical pollution.

5. Use: From the date of production more than 2 years, 2 samples should be sampled for less than 1000 samples for impact testing.

6. LitNet, Pingwang logo includes the following: 1 product name and classification mark; 2 side length of the mesh; 3 factory name, site; 4 trademarks; 5 manufacturing date (or number) or production batch number; 6 expiration date; 7 Safety production license number.

Each dense mesh should be firmly sewn with permanent signs including the above.

7. General rules for the use of safety nets:

(1) Installation requirements

1 Each tether on the safety net should be tied with the bracket, and the four surrounding ropes (edges) should be tightly attached to the bracket. The tie should be in accordance with the principle of knotting, which is easy to connect and easy to solve. Safety ropes with ribbed ropes should also be attached to brackets when installed.

2 The flat mesh surface should not be stretched too tightly. When the height difference between the mesh surface and the work surface is greater than 5m, the extension length should be greater than 4m. When the height difference between the mesh surface and the work surface is less than 5m, the extension length should be greater than 3m. The minimum distance to the surface of the object should not be less than 3m. The distance between two flat screens must not exceed 10m.

3 The vertical net surface should be perpendicular to the horizontal plane, and the maximum clearance with the edge of the working surface should not exceed 10m.

4 The safety net after installation shall be used only after being examined by a specialist.

(2) Use regulations

1 The following phenomena should be avoided during use

a) Casually dismantling the components of the safety net; b) Persons jumping in or putting items into the safety net; c) Massive welding or other Mars falling into the safety net; d) Accumulating objects in or under the safety net; e) Safety nets There are severe corrosive fumes around.

2 The safety net in use should be checked regularly or irregularly, and the netting pollution should be cleared in time. When the impact is greater, it should be promptly replaced.

8. Sampling and testing the number of samples: flat net (vertical net) of each specification, material, a rope sample 3; dense mesh safety net each specification, material 2 pieces of rope sample 3 .
