Ladders used for escape on a roof should be arranged with at least how many ladders, and on how many sides of the building?

• A. Two ladders on different sides
• B. One ladder on one side
• C. Three ladders on two sides
• D. Two ladders on the same side only

Answer: (A)

Two independent escape routes are essential from the roof. Placing two ladders on two different sides of the building gives you a true second option if one side becomes blocked by fire, smoke, or debris, ensuring occupants or firefighters can still reach safety. Ladders on the same side don’t provide that redundancy—the same hazards on that side could render both ladders unusable. One ladder is not enough for reliable egress, and having three ladders on two sides adds clutter without adding the essential benefit of an alternate, unobstructed path.
