According to statistics, up to 85% of the victims of fire died not from burning or thermal radiation, but from poisonous gases such as carbon monoxide and hydrogen cyanide produced by the burning of building structures and decorative materials. Most of the victims had asphyxiated before they were burned. Fire-fighting filter self-rescue respirator can effectively protect people from carbon monoxide (CO), hydrogen cyanide (HCN), toxic smoke, fire retardant and heat insulation, which provides an opportunity for people to escape from the smoke. It can be widely equipped in high-rise buildings and civil buildings, hotels, banks, shopping malls, entertainment halls and factories. It is an effective respiratory protection device for emergency evacuation in fire.
