Don’t be in doubt, know your exit route!
How would you escape from your workplace in an emergency? Do you know where all the exits are in case your first choice is too crowded? Are you sure the doors will be unlocked and that the exit access, such as a hallway, will not be blocked during a fire, explosion, or other crisis? Knowing the answers to these questions could keep you safe during an emergency.
What is an exit route? An exit route is a continuous and unobstructed path from any point within a workplace to a place of safety.
An exit route consists of three parts:
- Exit access: the portion of an exit route that leads to an exit.
- Exit: portion of an exit that is generally separated from other areas to provide a protected way of travel to the exit discharge.
- Exit discharge: part of the exit route that leads directly outside or to a street, walkway, refuge area, public way, or open space with access to the outside.
