Fire Escapes : When a fire breaks out in a building, it is not unusual for people to panic. Sometimes flames can spread rapidly, especially if fanned by blow of air from open or broken windows and doors, and blinding and choking smoke can soon envelop clear spaces. In such circumstances it is essential that escape routes are well known, clearly indicated and free from obstruction. Suitable escape routes are not susceptible to blockage or failure in emergencies. Similarly alarm points and assembly areas must be well indicated and accessible.
