Planning & EstimatingQuestion 542 of 700
A basement bedroom plan shows an emergency escape and rescue opening with a clear opening HEIGHT of 22 inches and width of 30 inches. What is the BEST assessment?
a.It fails because the clear opening height is below the 24-inch minimum
b.It passes because the width exceeds 20 inches
c.It passes because total area is over 5 square feet
d.It fails only if the sill is above 44 inches
Explanation
An emergency escape opening must provide a minimum net clear opening height of 24 inches and width of 20 inches, in addition to meeting a minimum net clear opening area. At 22 inches, the height fails regardless of width or overall area. Options b and c ignore that each dimension must independently be met. Option d addresses a separate sill-height rule. Both minimum dimensions and minimum area must all be satisfied.
