What issues should be paid attention to when buying a anti-collision work cap?
Not only plastic caps can be called anti-collision work caps, but ordinary manufacturers cannot casually produce anti-collision work caps. Anti-collision work caps are widely used in industrial production and belong to protective equipment, whose function is to protect the safety of workers. Manufacturers of safety helmets must have an industrial production license for special protective equipment. Because it is a special protective equipment, it must meet national requirements and standards. The mandatory standard for safety helmets in China is "Helmets" GB2811-2007, which stipulates the physical performance requirements, technical performance requirements, inspection rules, management, marking and packaging of industrial safety helmets. It is suitable for safety helmets commonly used in industry, and other added special properties are only suitable for corresponding special places.
Manufacturers of anti-collision work caps must pass the system approval of the competent department and have self-inspection capabilities. Its products must pass the inspection of the inspection agency designated by the state and pass random inspections in batches. When choosing a safety helmet, you must choose a safety helmet that meets national standards, has complete signs, and has passed the inspection. When purchasing safety helmets, users should also check their recent inspection reports, which are provided by the manufacturer. And choose different varieties according to different protection purposes. For example, if you work in a fire-proof place, you should choose a safety helmet with anti-static function when purchasing a safety helmet, otherwise the protection function will not be achieved, causing certain safety hazards. So what should you pay attention to when buying a safety helmet? Today, the editor of China National Defense Network will provide you with some popular science to help you better choose a helmet that meets your needs.
Helmets can be divided into ordinary helmets and special function helmets
Anti-collision work hat has two basic attributes:
Impact resistance: The impact test should be carried out at a high temperature of 502, a low temperature of -102, and water immersion, from a height of 1 meter, with a 5 kg steel hammer falling, and the maximum resistance of the head should not exceed 4900 N.
Puncture resistance performance: In the environment of high temperature 502, low temperature -102, and water immersion, a steel cone weighing 3 kg is dropped from a height of 1 meter for the test. The steel cone should not be in contact with the headform.
Special function helmet, as long as the specific working environment requires the helmet to have a specific protective function, it is mainly divided into several functions
Insulation helmet: tested according to national standards, leakage The current does not exceed 1.2 mA, mainly used in live working environments.
Flame retardant safety helmet: test according to national standards. The afterburning time shall not exceed 5 seconds, and the cap shall not burn through.
Antistatic safety helmet: the surface resistance value is required to be no more than 1 109.
Lateral rigid helmet: tested according to the requirements of national standards, the maximum denaturation does not exceed 40 mm, and the residual denaturation does not exceed 15 mm.
When purchasing a safety helmet, it should be reasonably selected according to the place of use and special functional requirements, and should be used and maintained correctly according to its structural characteristics and protective performance. Don't underestimate hard hats. Only with it will you be safe.
