83. If it should become necessary to abandon a compartment because of the danger of a large steam leak on a boiler, which of the following actions represents the best avenue of escape?

To escape a compartment with a large steam leak, moving laterally into a lower-level compartment provides the safest route by avoiding the upward flow of hot steam and placing a barrier between you and the hazard; elevators and upward routes expose individuals to the most dangerous conditions, while a lateral move to a lower level offers cooler air and a secure escape path.
