Fire helmet cleaning and maintenance

When on fire helmet shell is clean, use soap and water and soft cloth to clean. Don't recommend the use of grinding sand mold cleaning sponge surface screen and safety goggles, recommend the use of fire helmet supplier sea on offer professional detergent and soft cloth to clean, ensure the cleaning of the surface screen without damage. When clean cap lining, the cap can be lined with about 30 degrees Celsius temperature with mild detergent to clean warm water. As far as possible using tap water rinse cap inside the shell. Note: do not use hydrocarbon cleaning products or solvent cleaning and fire helmet surface screen and goggles.

After cleaning the fire helmet you need for each part, especially all the link of a thorough examination. Mainly check the correct part fixed way fixed parts, secondly whether there is a visible wear parts, helmet whether any damage. Ensure the normal regulation of the fire helmet. If there are parts damaged parts, it is only through the helmets are accredited suppliers to buy parts for installation, in order to ensure that the helmet in conformity with the specifications. Recommendations on a regular basis to qualified institutions to test whether a helmet to use standard.

If fire helmet clean up is completed, you can put on the helmet specific protection bag, or seal, such as closet, cabinets, etc. Storage place as far as possible away from humidity, illumination and exhaust gas. Avoid falling when stored in or knock against, because it may lead to damage of mask, helmet weaken shock absorption system function or damage to the surface protection coating. 

Helmet is to prevent physical damage to the head impact protection products

 Helmet is to prevent physical damage to the head impact protection products . By the cap shell , cap liner , and rear lower cheek with hoop components. Hemispherical cap shell , firm, smooth and have a certain flexibility , impact and puncture combat substance mainly composed of the cap shell to withstand the kinetic energy . Cap shell and leave some space between the cap liner can be buffered , dispersing instantaneous impact, so as to avoid or mitigate the direct damage to the head . Absorption of the impact properties, puncture resistance , lateral stiffness , electrical insulation , flame resistance is a helmet basic technical performance requirements.

Helmet can withstand the pressure is mainly used three principles : 1. Buffer damping effect : cap shell and cap liner between 25 ~ 50mm gap , when the object hit the Fire helmet , the cap shell deformation is not due to a direct impact to the head at the top . 2 . Dispersing stress : cap shell is oval or hemispherical , smooth surface , when the object fall on the cap shell , the object can not stay immediately fall ; And cap shell hit points to withstand the force transmitted to the surroundings through the cap lining cushioning to reduce the force of up to 2 /3 of the rest of the force through the cap liner gives the entire area of ??the skull to pass , so put the focus on the surface becomes a focal point , thus avoiding the impact force to a point on the cap shell stress concentration and reduce the force per unit area . 3 . Biomechanics : GB forth helmet must be able to absorb the 4900N. This is because the biological tests , the force in human cervical maximum limit , exceeding this limit will be harmed cervical spine , the light causing paralysis , severe life-threatening.
