The GA44-2004 standard, with the impact of anti - sharp objects, corrosion, heat radiation, the reflective insulation performance. Shell made of high temperature imports polyetherimide plastic, impact, puncture, high-density foam buffer layer are power buffer network and cap hoop quadrupole damping structure to maximize slow the external head position of impact. Helmets as a whole has a very high temperature resistance, the helmet shell temperature of 260 ℃. With high strength, high resistance to penetration, and the excellent performance of anti-electric shock, fire-retardant and heat. Mask lens has a good transmittance, high clarity, impact resistance, excellent performance, heat resistant, anti-fog, scratch resistant, radiation and anti-aging performance. 

 Korean fire helmets, protective properties to the American standard, comfort and user-friendly reference to European standards, 
 Maximum impact force: 3525N. Shell quality: <1 kg, the total mass of <1300g. Its impact absorbing properties to meet the standard requirements of GA44-2004 "Fire Helmet". Heat resistance: cap shell can not be touched head modulus qualified. Cap shell along the deformation sagging 3.2mm. (The standard requirements of ≤ 40mm). Peak deformation sagging 2.4mm (standard requirement ≤ 30mm). Both sides of the cap shell deformation sagging 4.6mm (standard requirement ≤ 30mm). Hat bands, hat care, the buffer layer and the chinstrap should be no significant deformation damage, to meet the standard requirements. Thermal deformation properties: Qualified. Drop Performance: Qualified. Under the chin with a tensile strength: qualified. The extension length of 7.8 
 mm (standard ≤ 20mm). Lateral rigidity: the maximum deformation of the cap shell is 38.2mm (standard ≤ 40mm). Deformation after unloading for the 6.2mm (standard requirements of ≤ 15mm). Electrical insulation properties: cap shell leakage current 1.5 
 mA (standard ≤ 3mA).
