Abstract: Due to the inherent fire risk in occupancies, it necessary that they are provided with suitable and sufficient escape route in case of fire emergency. This will ensure that occupants can get to a place of relative safety within the shortest period of time without travelling excessive distances or encountering hindrances. This paper is resultant of a study conducted on fourteen commercial highrise buildings in Nairobi CBD. It assesses essential fire escape route elements in the light of the requirements of the national regulations, laws and standards.
