As one of the important products of safety protection products, the safety helmet is based on the mandatory standards of national standards for safety helmets. The safety helmet is calculated from the date of completion of manufacture. The maximum period of use of the plastic safety helmet is 3 years, and the service period of the glass safety helmet is 2 years. half. After the expiry of the use of the unit must go to the relevant departments through the helmet detection equipment for the helmet test, qualified before they can continue to use, otherwise the batch of helmets that are scrapped.

Security experts pointed out that each helmet can be “checked” by helmet testing equipment. The quality of the "healthy" condition of the helmet is determined by the data detected by the helmet detection equipment, avoiding blind use. At the same time, during the test, a file was created for the helmet and the logo was made so that its health status was well documented. After testing, unqualified helmets should be scrapped and destroyed, and must not be used indefinitely. Safety is no small matter. The issue of overdriving safety helmets should not be underestimated, and everyone should pay enough attention. In particular, the safety supervision department should supervise and inspect the over-time use of safety helmets in the daily safety inspection and eliminate the safety helmets. The safety hazards caused by the extended use of the helmet make the helmet play a good role in its safety protection. Field safety inspectors generally focus on checking whether workers are wearing and whether they are wearing it correctly, but few people are concerned about its extended use. The problem of excessive use of safety helmets should be given enough attention. Because of the long-term use of the helmet, the helmet shell material becomes brittle, its impact absorption performance (tested by a helmet impact tester), puncture resistance (tested by a helmet puncture tester), and lateral rigidity (safety Cap lateral rigidity tester detection, electrical insulation (hard hat electrical insulation tester test) and flame retardant (hard hat flame retardant tester test) will be greatly reduced, the surface does not have the ability to fight, can not meet the security The basic technical performance of the cap does not provide the protective effect that the helmet should have on workers.

However, according to the survey, most employees do not know that helmets have a shelf life. To use the helmets if they want to continue using them, they need to send professional inspection agencies to carry out quality inspections through helmet testing equipment. A helmet is used for 5 years or even 10 years. The situation is not uncommon. What is more, in order to save costs or management is not standardized, some units have not strictly followed the cycle of product rotation or quality inspection in terms of the issuance of labor protection products.
