Is your helmet "healthy"?

A worker's master wearing a helmet accidentally stumbles on a small screw and is on the spot. After inspection by related departments, the helmet has already exceeded the service life. Although the interior of the helmet has a sponge-like liner, it has been used for a long time. The hard hat outer shell material has become brittle and the surface has no anti-attack ability.

The safety helmet is a protective tool during labor production, and is also a personal insurance cap. The protective effect of the protective object can not be ignored. Now, in the safety helmets that protect the lives of people, we have seen security risks. At the production site, people generally pay attention to whether or not the worker is wearing it, and there is little concern about the age of the worker. The author found at the grassroots random visit, most employees do not know that helmets have a shelf life, and some people said that wearing a hat is just to look like, to cope with inspections, the key time can not be of any use.

It is understood that the normal service life of ordinary helmets is 2.5 years, but the use of helmets on the job site is extremely common, and some security managers are indifferent. An enterprise has had a hard hat for nearly 10 years. Because it looks "new" and looks "nothing," it is still used indefinitely.

The long-term use of the safety helmet, the helmet shell material is easy to be aged and brittle, and the impact absorption performance, puncture resistance, lateral rigidity, electrical insulation and flame retardancy are greatly reduced, and the surface does not have the anti-strike ability and cannot meet the requirements. The basic technical performance requirements of helmets do not achieve the protective effect that helmets should have on workers. The phenomenon of cap top breakdown and hat splitting is not uncommon. The annual safety accidents caused by aging failure of safety helmets occur frequently. . According to the compulsory standard for safety belts and helmets, the safety helmet shall be calculated from the date of completion of manufacture. The maximum period for use of the plastic helmet shall be 3 years, and the period of use of the glass helmet shall be 2.5 years. After the expiry of the use of the unit must go to the relevant departments to carry out spot checks, can only continue to use qualified, otherwise the batch of helmets will be scrapped.

Safety experts point out that each safety helmet can be “checked” by a safety tool tester. The quality of the “healthy” condition of the helmet is determined by the data from the tester. It can avoid blind use. At the same time, it establishes archival information for the helmet during the test, makes a good identification, and issues an “identity card” to make it healthy. According to inspection. After testing, the unqualified seat belts and safety helmets are destroyed and must not be used indefinitely.

Lessons from the accidental upset of the warning warned us that the problem of excessive use of safety helmets should not be underestimated, and that everyone should pay enough attention. In particular, the safety supervision department should supervise and inspect the on-site safety helmet overdue use during routine safety inspections. Each year, we must conduct a comprehensive safety "health check" on the helmets, order "unless laid-offs" on unqualified helmets, eliminate the hidden dangers caused by the overuse of the helmets, and allow the helmets to truly play their due role in safety protection. .
