Personal protection equipment has a wide variety of products and covers a wide range of fields. Correct selection is a prerequisite for ensuring the safety and health of producers. In 1989, China issued the National Standard for the Selection of Labor Protection Products (GB/T11651-1989), which provided a basis for the selection of personal protective equipment. The selection of personal protective equipment should follow the following principles: 1. According to the work environment and nature to determine the type of operation selected personal protective equipment 2. Equip personal protective equipment according to the relevant laws and regulations of the country (previously issued by the State Economic and Trade Commission on March 6, 2000, "Standard for the Provision of Labor Protective Equipment (Trial)"). 3. Personal protective equipment with production licenses and safety signs should be purchased. Special personal protective equipment: safety helmets, safety belts, safety nets, dust masks, filter gas masks and filter jars, welding goggles and masks, impact eye protectors, flame retardant protective clothing, anti-static overalls, and acid proofing Workwear, protective toe safety shoes (leather safety shoes and rubber surface flood control safety boots), anti-static shoes, conductive shoes, acid-resistant shoes (boots), insulated leather shoes, low-voltage insulating rubber shoes, and anti-puncture shoes, etc. Licensing system. The production of these products cannot be produced without a license, and a "safety certificate" must be affixed to the product. When purchasing, you should check whether there are "two certificates". If there are no illegal products, it may be a shoddy product whose quality does not meet the standards. 4. Regarding the term of use and the principle of retirement. The period of use of personal protective equipment is determined by various factors, and is closely related to the environmental conditions of the workplace, the frequency of use of the equipment, and the material of the equipment itself. Take the example of a safety helmet issued by a factory and mining company in a province. In the metallurgical operation, the slab operation in a rolling mill is 36 months, and the cold work is 48 months. In coal operations, civil engineering operations are generally A maximum of 24 months; a pitman, installer, driller, and sampler in the geology industry is on top of 12 months. In general, the following three principles should be taken into consideration: (1) Degree of corrosion (According to different operations, the wear of the product can be divided into heavy abrasion, medium abrasion and light abrasion): It reflects the operating environment and the use of the type of work. (2) Loss conditions (Depending on the extent to which the product's protective function is reduced, it can be classified as prone to wear, medium to wear, and obsolete): reflect the product's protective performance. (3) Durability (can be divided into durable, medium-duration, and not durable): reflect the material condition of the product, such as flame-retardant protective clothing made of high-temperature flame-retardant fiber fabric, and flame retardant fabric treated with flame retardant The flame retardant protective clothing made is durable. Personal protective equipment shall be scrapped when it meets one of the following conditions, and shall not be used as personal protective equipment. (1) Does not comply with national standards or industry standards or local standards. (2) The functional indicators specified in the relevant standards and procedures for higher-level safety production have not been reached. (3) It is damaged or exceeds the effective period of use during use or storage and storage period. After inspection, it has not reached the minimum target of effective protective function of the original regulations.
