The service life and scrapping principle of commonly used special protective articles

First, the use of special protective equipment for years of use 1, the use of seat belts After using the seat belt for two years, should be a batch purchase of people sampling once. If qualified, the safety belt can continue to be used. For the tested sample belt, the safety rope must be replaced before it can be used again. Use frequent ropes. Always check the appearance. If any abnormalities are found, replace them with new ones. The belt is used for 3 to 5 years.

2. Precautions for anti-static shoes and anti-static overalls (1) GB12014-89 “Electrostatic Workwear” stipulates that when using anti-static clothing, it must be worn with the anti-static shoes specified in GB4385.

(2) Due to multiple washings, the anti-static performance of anti-static overalls will be reduced. Therefore, the operating period set by enterprises with high ambient temperature, high labor intensity, and frequent washing times should be appropriately shorter.

(3) During the wearing process of anti-static shoes, the resistance test should not be performed for more than 200 hours. If it fails, it cannot be used.

3. Precautions for the service life of electrically insulating shoes and insulating gloves Electrically insulating shoes include: electrical insulating leather shoes, cloth rubber shoes, rubber surface rubber shoes, and plastic shoes. Each unit can reasonably establish the use period according to the labor intensity and operating environment. But pay attention to the following: First, storage, since the factory day more than 18 months, only to conduct electrical performance preventive testing; Second, where the bottom of the corrosive damage, can not be used for electrical insulation shoes; Is to conduct at least one electrical performance test every 6 months during use. If it fails, it cannot be used. The period of use of insulating gloves, each unit can be made according to the frequency of use to make provisions, but must be required before each use blow air self-test, at least once every six months to do an electrical test, if not qualified to continue to use.

4. Precautions when equipped with a hearing protector The hearing protector includes a noise-proof earplug, a noise-proof earmuff, and a noise-proof helmet. In general, the anti-noise helmet has the best anti-noise effect. It can not only block the air conduction noise, but also can reduce the damage of the bone conduction noise to the ear. It should be used in a strong noise environment, and the anti-noise performance of the earmuffs should be followed. The ear plugs have the worst anti-noise effect, and the general sound attenuation values ​​in the 1000 to 2000 Hz band are only 10 to 20 dB.

Second, the principle of retirement of special protective equipment In general, the use of the following three principles should be considered:

1, the degree of corrosion According to different operations on the wear of labor protection supplies can be divided into heavy corrosion operations, corrosion operations and light corrosion operations. The degree of corrosion can reflect the operating environment and the use of the type of work.

2. Losses According to the degree of protection function reduction, it can be divided into vulnerability to loss, moderate loss and mandatory scrap. The loss status reflects the protection performance of the product.

3, durability According to the use of the cycle can be divided into durable, medium durable and not durable. The durability performance reflects the material condition of labor protection articles, such as flame-retardant protective clothing made of high-temperature flame-retardant fiber fabrics, and durable than flame-retardant protective clothing made of flame-retardant fabrics treated with flame retardants. Durability reflects the overall quality of protective equipment.

Third, there are several misunderstandings in the use of personal protective equipment

Myth # 1: Personal protective equipment can be worn or not

Experts pointed out that personal protective equipment can eliminate or reduce the impact of occupational disease hazards on workers' health. The Occupational Disease Prevention Act stipulates that employers must provide workers with protective equipment that meets the requirements, and that workers are obliged to wear protective equipment.

Misunderstanding 2: No odor in the workshop, you can not wear personal protective equipment

Experts pointed out that many of the harmful gases are colorless, odorless, tasteless, and do not have any alertness and do not feel it. Even if it is odorous, there are limitations and individual differences in the sensory organs' perception of the outside world. Therefore, excessive belief in feelings may lead to occupational poisoning.

Myth #3: Gauze masks can be used to prevent dust

Ordinary gauze masks cannot be used as dust masks. The gauze masks we use today are cheap, sweat-absorbent in the summer, and warm in the winter. However, such masks (even if they are 16 layers thick) cannot protect against the hazards of respiratory dust from pneumoconiosis. Special dust masks are required for dust protection.

Myth 4: Medical Masks Used to Prevent Drugs

Medical masks can prevent disease from spreading through droplets, but they cannot filter toxic gases. For different poisons, use different respirator masks. General volatile organic gases can use activated carbon respirator.

Myth 5: Dust masks washing and reuse

Dust mask filter material can not be washed. The high-efficiency filters used in dust masks are usually non-woven materials, and some rely on electrostatic charges on fibers to filter respiratory dust. After washing, the microstructure of the filter material is impaired, cracks and holes that are invisible to the naked eye occur, electrostatic charges are also greatly lost, and the filtration performance is severely degraded.

Protective equipment is a passive protective measure. In any case, it should first adopt advanced production technology, do a good job of engineering protection facilities to actively prevent occupational diseases, and consider it as a protection facility if it cannot completely eliminate the occupational hazards. Workers are equipped with appropriate personal protective equipment. It is worth noting that personal protective equipment is not a panacea, and any personal protective equipment has its applicability, and it has limitations. It needs to consider the use of the environment and the scope of application of protective equipment. (Source: Occupational Health Network)
