When traveling through a smoke-filled area a person must be able to see for a distance of at least in order to safely reach a fire exit?

When traveling through a smoke-filled area, a person must be able to see at least 6 to 8 feet in front of them to safely navigate towards a fire exit. This visibility distance allows for better awareness of obstacles and ensures a clearer path to safety. If visibility is less than this, individuals should stay low to the ground where the air is clearer.
