90% of fires occur inside buildings, where we spend on average 90% of our time. Today a fire can engulf a room in 3 minutes compared to 25 minutes 50 years ago, and this change has come about because of the increase of plastics in our homes.
People escaping often have only a few minutes to leave a building safely before the development of smoke makes orientation increasingly difficult. This fact makes identifying escape and rescue routes impossible. Dense and corrosive fumes make the activity of rescue teams more difficult and dangerous.
