How many years is the life cycle of the helmet?
The helmet will be progressively damaged during use and shall be visually checked regularly. If the cap shell and the liner are found to be abnormally damaged or cracked, or the horizontal vertical spacing between the hat liner and the top of the hat shell is not up to the standard requirement, the helmet can not be used again, and a new safety helmet shall be replaced. When the helmet is not used, it should be placed in a dry and ventilated place, away from the heat source and not exposed to direct sunlight, so as to ensure that the protective function is not affected during the effective use period. Pay attention to the use of time: FRP helmet generally not more than three years, expired safety helmet to be tested, in line with safety requirements can continue to use, otherwise it must be replaced.
As a personal head protection product, the helmet can effectively prevent and reduce the injury to the human head when the operator suffers the falling object or falls from the production operation. The safety helmet is composed of a hat shell, a cap lining, a chin belt and a back hoop. Although we can not do without it in our work, the specific method of use may not be fully understood by everyone. Incorrect use and storage will result in the helmet not being able to protect itself when it is hit. According to statistics of the departments concerned, 15% of the accidents caused by falling objects are caused by improper use of helmets.
The use of safety helmet, safety helmet for the first choice with their heads, wearing helmets, to carefully check the certificate, instructions for use, use period, and adjust the size of the top cap lining, and the inner top of the helmet casing must be maintained between 20-50 mm space. With this space, in order to form an energy absorbing system, so that the impact force suffered by the distribution in the whole area of the skull, to reduce the head injury; secondly, not free to remove safety cap or add attachments, so as not to affect the original protection performance; must be safety cap, wear. And can not shake, to fasten the jaw belt, after adjusting hoop, to prevent the safety helmet off.
In order for helmets to play a better role in protection, it is necessary for us to have a better understanding of their use requirements. In the shell material, the helmet has low pressure polyethylene, ABS (engineering plastics), glass fiber reinforced plastic and rubber material, Taketo and other materials made of different materials. Some helmets also have additional functions, such as electricity alarm, safety helmet, noise proof safety helmet, electric welding face mask, safety helmet and so on. At present, most of the petroleum workers wear glass fiber reinforced plastic safety caps, which have the characteristics of strong rigidity, high temperature resistance and corrosion resistance. They are suitable for steel, underground, mine and other special operations.
