How many years is the validity of FRP and plastic safety helmet?

The safety helmet is valid for one and a half years from the date of purchase. Plastic caps are not more than two years, laminated caps and FRP caps are two and a half years, rubber caps and cold-proof caps are three years, and riding helmets are three and a half years. The safety helmet is easy to age beyond its general service life and lose its protective performance.

I) type of safety helmet

A helmet is used to protect the human head from external force, which consists of a helmet shell, a hat lining, a chin strap, a back hoop, etc. Safety helmets are divided into six categories: universal, riding, special, military helmets, military protective hats and athletes' protective hats. Among them, universal and special safety helmets belong to labor protection articles.

1, universal helmet

There are two kinds of this kind of hat, which only prevent top and side impact. It has the characteristics of puncture resistance and is used in the construction and transportation industries. The universal safety helmet used in places with fire sources is flame retardant.

2. Special safety helmet

(1) electrical safety helmet. The insulation performance of the cap shell is very good, and it is widely used in electrical installation, high-voltage operation and other industries.

(2) Anti-static safety helmet. The antistatic agent is added to the materials of the cap shell and the cap lining, which is used in places with explosive substances such as combustible gas or steam. According to the 0 zone and 1 zone specified in the Electrical Safety Regulations for Explosive Dangerous Places, the minimum ignition energy of combustible substances is above 0.2 MJ ..

(3) cold safety helmet. Good low-temperature characteristics, cotton cloth, fur and other warm-keeping materials are used as fabrics, and they can be used in the environment where the temperature is not lower than -20℃.

(4) High-temperature and radiation-resistant heat safety helmet. It has good thermal stability and chemical stability, and is used in places with radiant heat sources such as fire fighting and smelting.

(5) Safety helmet against lateral pressure. High mechanical strength and bending resistance, used in forestry, underground engineering, underground coal mining and other industries.

(6) Safety helmet with accessories. A helmet with accessories that meets certain use requirements.

(B) the use of safety helmet

According to the statistics of relevant departments, 15% of people who were injured by falling objects from high altitude were caused by improper use of safety helmets. So you can't think that wearing a helmet can protect your head from impact injuries. In practical work, we should also understand and do the following:

(1) All personnel who enter the production site or engage in productive labor inside and outside the factory must wear safety helmets (unless there are special regulations in the country or industry; Special operations or labor, except that measures can be taken to ensure that the head of personnel is not injured and approved by the safety supervision department).

(2) When wearing a helmet, you must fasten the helmet strap to ensure that it does not fall off under various circumstances; The brim of safety helmet must be consistent with the visual direction, and it is not allowed to wear it askew or obliquely.

(3) It is not allowed to disassemble the parts on the cap and adjust the size of the cap liner without permission, so as to keep the vertical spacing and horizontal spacing in line with the relevant specified values and prevent personal injury caused by hitting the top after impact.

(4) It is forbidden to put anything on the hat lining. It is forbidden to change any mechanism of safety helmet at will. Do not use the safety helmet as a container. It is forbidden to use safety helmet as cushion.

(5) The safety helmet must have instructions for use and indicate the place of use for workers' reasonable use.

(6) Always keep the cover gasket clean. If it is not clean, rinse it with soapy water and clean water. Don't put it in a place with acid and alkali, high temperature, sunshine, humidity and chemical solvents after use.

(7) Helmets subjected to severe impact in use can no longer be used.

(8) If the cap shell and cap liner are aged or damaged, which reduces the impact resistance and penetration resistance, they can no longer be used, and a new cap should be replaced.

(9) Anti-static safety helmet cannot be used as a safety helmet in the electrical industry, so as to avoid problems.
