Generally speaking, the effective use period of helmets is about one and a half years. However, the materials are different, so the actual use time is also different. For example, the use time of plastic safety helmets is not more than two years, while the use time of laminated caps and glass fiber reinforced plastic caps is about two and a half years. Rubber caps and cold caps should be used for three years. Years, helmets can be used for a maximum of three and a half years.
The time limit for use is only a meaningful time, and the actual time limit for use is difficult to reach this length of time. Because in the process of use, many inappropriate use methods will damage the service life of the helmet.
Therefore, in the process of using the helmet, you need to pay attention to the following matters:
1. It is strictly forbidden to change any structure of the helmet at will, so as not to cause the helmet to lose its protective effect and reduce the service life.
2. It is forbidden to use the safety helmet as a seat cushion or other functions other than head protection, so as not to damage the aging time of the safety helmet and reduce the protective performance of the safety helmet.
3. Do not graffiti or paste pictures and text on the helmet.
4. The safety helmet should be stored away from acid and alkali, high temperature, humidity and direct sunlight, and should not be placed with other hard objects.
5. The service life of the helmet should be calculated from the date of manufacture and needs to be replaced regularly.
6. After the new helmets are issued, the old helmets cannot be used again and should be handed in in time.
Only by mastering the appropriate method of use and paying attention to the corresponding matters, can the protective performance of the helmet be better played.
