Any area of work where it is necessary to travel between two or more levels on a regular basis must be equipped with fixed industrial stairs to provide a permanent point of access for workers. a. false b. true

B. TRUE!! Stairs can be used as a emergency fire exit (In case the elevators blow up in a fire) And stairs can be used even in general. If you're late to work, and all the elevators are hogged, then you can run up the stairs. 

True because how are you able to travel without any stairs
