Safety helmet can not be used beyond the time limit

recently, on the construction site of a petrochemical enterprise, an employee wearing a safety helmet was accidentally knocked down by a cement block when working, and his head was broken on the spot. After the inspection by the relevant departments, the safety helmet worn by the employee has already exceeded the service life, and the shell material of the safety helmet has become brittle and does not have enough impact resistance

the safety helmet is not only a protective tool in labor production, but also a personal safety helmet, and its protective effect on striking objects can not be ignored. Now, in the safety helmet to protect human life, we see the hidden danger. Many enterprises only pay attention to whether the workers wear safety helmets, but few people care about the service life of safety helmets. The author also found that most of the employees did not know that the safety helmet also has a shelf life, and even some people said that wearing the safety helmet is just a show to cope with the inspection, which is not useful at the key time

according to the mandatory national standard for safety helmets, the maximum service life of plastic safety helmets is 3 years and that of FRP safety helmets i2.5 years from the date of completion of manufacture. After the expiration date, the user must go to the relevant departments for spot check and test, and can continue to use it only after it is qualified, otherwise it should be scrapped immediately. However, in fact, it is very common that safety helmets are used beyond the time limit. Some safety helmets of an enterprise have been used for nearly 10 years, and they are still used indefinitely

if the safety helmet is used for a long time, its shell material is easy to be aged and brittle, and its impact resistance, puncture resistance, lateral rigidity, electrical insulation and flame retardancy will be greatly reduced, which can not play the role of protection for workers. 1t is understood that every year due to the aging failure of the safety helmet caused by the size of accidents occur from time to time

safety protection experts pointed out that “physical examination” can be carried out for each safety helmet through the safety tool detector. Safety helmet health condition has the final say of the tester data, avoid blind use. At the same time, during the test, the safety helmet should be provided with file data, well marked and issued with “1D card” so that its health status can be verified. After testing, the unqualified safety helmet should be scrapped and destroyed, and must not be used indefinitely

the lessons we have learned from each other are that we should not underestimate the problem of over use of safety helmets, and we should pay enough attention to it. Especially the safety supervision department, in the daily safety inspection, should do a good job in the supervision and inspection of the problem of safety helmet overdue use, carry out a comprehensive safety inspection on the safety helmet every year, order the unqualified safety helmet to “lay off”, eliminate the safety hidden trouble caused by the safety helmet overdue use, and let the safety helmet really play its due role in safety protection
