12.1.1.1-8 Emergency Exit Features

In designing and constructing emergency doors and exits, ensure that they:

 

  1. are simple to operate
  2. are readily accessible
  3. are clearly designated
  4. are unobstructed
  5. are simple to locate and operate in the dark
  6. are capable of being opened in 3 seconds or less
  7. require between 44 and 133 N (10 and 30 pounds (lb)) of operating force to open
  8. permit exit by one person in 5 seconds or less
  9. do not, in themselves or in their operation, constitute a safety hazard

 

Additional Information. A door that is not blocked in the direction of exiting travel is not considered an obstruction. An inside door under low occupancy conditions should not be less than 71 centimeters (cm) (28 in.) in width. When other factors (such as necessary emergency clothing or equipment) are considered, these minimal dimensions should be larger. HFDS
