How long can the helmet be stored without use?

We all know the importance of safety helmets, but lack of attention to the validity period. As long as there is no obvious damage, they will be used all the time. Many users even wear a safety helmet for many years, which poses great safety risks. The validity period of safety protection products is a very important parameter. Whether it is buying or using a helmet, the first thing to pay attention to is whether the helmet is within the validity period and how long it can be used. Generally, the longest service life of a plastic safety helmet is 3 years, and a fiberglass safety helmet is 2 and a half years. Of course, due to differences in materials and technical methods, the validity period of different manufacturers may vary. Many users have this misunderstanding, thinking that the helmet will not expire without being used. Here we need to solemnly remind everyone that according to the requirements of GB2811-2007 "Hard Hat" 6.2.10, even if it is not used, the material of the helmet will Aging, although no problems can be seen on the surface, the protective effect is greatly reduced, and there are hidden safety hazards. Each helmet will be marked with the production date on the inside, so the advice to everyone is that even if the helmet has not been used, check the production date before using it to confirm whether it is within the validity period. So can the helmets that have passed the production date but are intact can only be scrapped? Conditional use units can go to the relevant departments for performance testing, and they can continue to use it if they pass the test. However, they need to be tested regularly every month. For individuals, it is more convenient and trouble-free to replace a new helmet. There is also a special case. After the helmet is hit, no obvious cracks, dents, etc. are found. Can the helmet continue to be used? The answer is no. As long as this happens once, the helmet will be immediately scrapped.

How to identify the quality of the helmet?

How to identify the quality of the helmet?

As a head protection product, the important role of helmets is self-evident. Many accidents are caused by not using helmets or using inferior helmets. Therefore, relevant workers must pay attention to the quality of helmets. Safety helmets must be produced in accordance with the national standard GB2811-2007 "Safety Helmets". Products delivered from the factory should pass the inspection of the safety supervision department and the quality inspection department. The safety helmets that meet the requirements of the standard will be issued with relevant qualification certificates. According to national standards, a qualified safety helmet should have the following four permanent marks: 1. Name, trademark and model of the manufacturer 2. Production date (including year and month) 3. Production certificate and inspection verification 4. Production license number After checking these four signs, you need to distinguish quality based on experience: Look thin and thick: Whether it is glass fiber reinforced plastic, ABS or other materials, high-quality helmets have a certain sense of thickness, and seemingly thin helmets often have poor impact resistance. Weighing weight: Thickness does not mean heavy weight. An overweight helmet will put pressure on the wearer's neck and cause fatigue. According to international standards for the weight of helmets, the small-edge and curled-edge helmets must not exceed 430g (excluding the weight of accessories), and the large-edge helmets must not exceed 460g. Hardness test: At present, there are more ABS helmets on the market, which have the characteristics of high strength and good toughness. However, some inferior helmets are mixed with other secondary materials, and they will break with a light drop. The protective effect can be imagined. We can lightly press the top of the hat with our thumbs when testing. If it is too soft, it is best not to choose. Qualification for the production of protective equipment is very important, especially when purchasing safety helmets online, you must check the manufacturer’s production qualifications. If you are an agent or distributor of a big brand, you must check the relevant certification to ensure that it is genuine. The test report provided by the manufacturer is, after all, a safety issue, so you can't be sloppy.
