We are only able to get away from a fire calamity when we are out of the house or building. But, what if we are still inside the building, plenty of things can happen that will our life at a huge risk. Fire smoke is very dangerous when no fire-rated wall or doors with smoke seals are installed in order to prevent the passage of smoke. In a fire accident, most casualties had fainted because of the inhalation of smoke. Fire can devour those people who have become unconscious when this takes place, and this will result in permanent damage and loss of life. But there is a better chance for people to be protected from the sudden spread of fire if there is a fire door.
