Basic requirements for the number of exit routes include:

Blocked Fire Exit
Question: What's wrong with the exit in the photo?
Answer: The exit is blocked.
  • The number of exit routes should be adequate.
  • At least two exit routes should be available in a workplace to permit prompt evacuation of employees and other building occupants during an emergency.
  • The exit routes should be located as far away as practical from each other so that if one exit route is blocked by fire or smoke, employees can evacuate using the second exit route.
  • More than two exit routes should be available in a workplace if the number of employees, the size of the building, its occupancy, or the arrangement of the workplace is such that all employees would not be able to evacuate safely during an emergency.
  • A single exit route is permitted where the number of employees, the size of the building, its occupancy, or the arrangement of the workplace is such that all employees would be able to evacuate safely during an emergency.

For assistance in determining the number of exit routes necessary for your workplace, consult NFPA 101, Life Safety Code.
