Safety helmet is a kind of protective equipment to prevent the head from being injured by impact objects. The utility model is composed of a cap shell, a cap lining, a lower cheek band and a back hoop. The cap shell is hemispherical, firm, smooth and elastic. The impact and puncture kinetic energy of the striking object are mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. 1mpact absorption performance, puncture resistance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements of safety helmet
shallow dome hat made of steel or similar materials worn by miners and underground engineering personnel to protect their heads. A lightweight protective helmet, usually made of metal or reinforced plastic, worn by workers in industrial environments. A cap worn by a worker during construction or mining to protect his head from falling objects. 1t is usually made of wicker, rattan core or plastic
classification of safety helmets
safety helmets can be divided into two categories according to their uses: general operation (y) safety helmets and special operation (T) safety helmets. Among them, the T category can be further divided into five categories: T1 category is suitable for workplaces with fire sources; T1 category is suitable for workplaces with fire sources; T2 is suitable for underground, tunnel, underground engineering, logging and other workplaces; T3 is suitable for inflammable and explosive workplace; T4 (insulation) is suitable for live working places; T4 (low temperature) is suitable for low temperature workplace. Each kind of safety helmet has a certain technical performance index and scope of application, so choose the appropriate products according to the industry and working environment.
consumers can choose the appropriate products according to their own needs, and choose the safety helmet according to the industry and working environment. For example, the construction industry generally chooses Y-type safety helmet; 1n the electric power industry, T4 (insulated) safety helmet should be selected due to contact with power grid and electrical equipment; T3 safety helmet should be selected when working in flammable and explosive environment. The color selection of safety helmet is quite random. Generally, light color or eye-catching color is appropriate, such as white, light yellow, etc. it can also be selected according to the requirements of relevant regulations, following the principles of safety psychology, according to the division of departments, and according to the workplace and environment
application fields of various safety helmets 1. FRP safety helmets are mainly used in metallurgical high-temperature workplaces, oil field drilling, forest cutting, power supply lines, high-rise building construction and construction in cold areas. Polycarbonate plastic safety helmet: mainly used in oil field drilling, forest cutting, power supply lines, construction and other operations. ABS plastic safety helmet: mainly used in mining, machinery industry and other indoor normal temperature workplaces with high impact strength. 4. Ultra high molecular weight polyethylene plastic safety helmet: it has a wide range of applications, such as metallurgy and chemical industry, mining, construction, machinery, electric power, transportation, forestry and geology. Modified polypropylene plastic safety helmet: mainly used in metallurgy, construction, forest, electric power, mining, well, transportation and other operations. 6 tape miner safety helmet: mainly used in coal mine, underground, tunnel, culvert and other places. When wearing, there is no mandibular frenulum. 7. Plastic miner’s safety helmet: the performance of the product is basically the same as that of the colloid miner’s helmet except that the high temperature resistance of the product is greater than that of the colloid miner’s helmet. 8. Cold proof safety helmet: it is suitable for field and open-air operators in cold regions of China in winter, such as mining, geological drilling, forestry logging, construction and port handling. 9 paper glue safety helmet: suitable for outdoor operation, anti solar radiation, sand and rain. Bamboo safety helmet: mainly used in metallurgy, construction, forestry, mining, wharf, transportation and other operations. Other woven safety helmet: it is suitable for use in hot areas in the South without open fire
summary of instructions for the use of helmet color in different industries
relevant national standards do not make guiding specifications for the use of helmet color, and different industries, systems and enterprises have different specifications, For example, several typical color specifications: Construction 1ndustry: Wine Red: leader Red: technician white: Safety Supervisor blue: electrician or supervisor yellow: other construction personnel; Guodian system: White: leaders, blue: managers, yellow: constructors, red: outsiders, petroleum system: White: managers, yellow: Safety Supervisors, red: operators
