A helmet is a protective device that protects the head from impact. It consists of a cap shell, a cap liner, a lower cheek band and a rear cuff. The cap is hemispherical, strong, smooth and flexible, and the impact and puncture kinetic energy of the striker is mainly absorbed by the cap. There is a space between the cap and the cap liner to cushion and disperse the instantaneous impact force, thereby avoiding or reducing direct damage to the head. Impact suction performance, puncture resistance, lateral rigidity, electrical insulation, and flame retardancy are requirements for the basic technical performance of the helmet.
Helmet structure and parts function Cap: Understand the impact and separate the falling object from the human body.
Cap: Hold the helmet in a defined position on the head.
Top belt: Disperses the impact force and keeps the shell floating, so as to disperse the impact force.
Rear hoop: The locking device for the headband.
Bottom strap: assists in maintaining the status and position of the helmet.
Sweatband: Sweat.
Cushion: Reduces impact when impact occurs.
The helmet products are divided into two categories according to the general operation type (Y type) helmet and special operation type (T type) helmets. Among them, the T category is divided into five categories: the T1 category is suitable for workplaces with fire sources; T2 is suitable for underground, tunnel, underground engineering, harvesting and other work sites; T3 is suitable for inflammable and explosive working places; T4 (insulated) is suitable for live working places; T4 (low temperature) is suitable for low temperature working places. Each helmet has certain technical performance indicators and scope of application, so choose the corresponding products according to the industry and working environment used.
Consumers can choose the right variety according to their needs. Choose a helmet based on the industry and operating environment you are using. For example, the construction industry generally uses Y-type helmets; in the power industry, T4 (insulation) helmets should be used for contact with power grids and electrical equipment; T3 helmets should be selected for operation in flammable and explosive environments.
The choice of helmet color is relatively random. Generally, it is suitable for light color or eye-catching color, such as white or light yellow. It can also be selected according to the requirements of relevant regulations. It should be selected according to the principle of safety psychology. Choose according to the workplace and environment.
Pay attention to the problem during use 1. Before use, check whether the appearance of the helmet is cracked, scratched, uneven, worn, whether the cap lining is complete, whether the structure of the cap lining is in a normal state, and if there are obvious defects on the helmet that affect its performance, it will be scrapped in time. So as not to affect the protective effect.
2. Users are not allowed to disassemble or add accessories in the helmet to avoid affecting their original protective performance.
3. The user can't adjust the size of the cap lining at will, which will directly affect the protective performance of the helmet. Once the falling object impact occurs, the helmet will directly hurt the wearer due to the wearing or the impact.
4. The wearer must wear the helmet in a positive and tight manner when using it. Do not shake it. Tighten the lower strap and adjust the rear hoop to prevent the helmet from falling off.
5. You can't punch holes in the helmet and don't bump into the helmet. Don't sit the helmet on the bench to avoid affecting its strength.
6. A helmet that has been subjected to an impact or has been tested shall be void and shall not be used again.
7. Hard hats should not be stored in an environment contaminated with acid, alkali or chemicals. Do not place them in high temperature, sun or wet places to prevent them from aging.
8. It should be noted that the helmet is used within the validity period, the helmet-woven helmet is valid for 2 years, the plastic helmet is valid for 2 years and a half, and the FRP (including vinylon steel) and colloidal helmets are valid for 3 and a half years. Safety helmets that exceed the expiration date should be scrapped. 'Qingdao helmet quality upgrade product platform
