If a structure is 60 feet tall, the collapse zone using the standard factor would be approximately what height?

• A. 60 feet
• B. 75 feet
• C. 90 feet
• D. 120 feet

Answer: (C)

The collapse zone is estimated using a standard multiplier of 1.5 times the building’s height. This zone marks how far debris could travel if the structure fails, so crews stay clear of that area. For a structure 60 feet tall, multiply 60 by 1.5 to get about 90 feet. So the approximate collapse zone is 90 feet. This quick rule of thumb provides a conservative safety distance, though real situations may require adjustments for irregular shapes or instability.
