Most of the big fires leading to serious human losses and asset damages are caused by asphyxiation. Victims may die of asphyxiation within 2-3 minutes. In addition to foam and automatic sprinkler systems, respirators are effective measures to escape fire. Apartment residents will feel assured when having special masks at home.
