Planning & EstimatingQuestion 502 of 700
A bedroom plan shows a single egress window with a clear opening of 5.0 square feet and a sill 46 inches above the finished floor. Based on typical emergency escape requirements, what should the plan checker flag?
a.The sill height exceeds the maximum and the clear opening is below the minimum
b.Nothing; bedrooms do not need egress windows
c.Only the glass type matters
d.The window is oversized and should be reduced
Explanation
Emergency escape and rescue openings in sleeping rooms generally must provide a minimum clear opening of about 5.7 square feet (5.0 sq ft is allowed only at grade-floor openings) with a sill no more than 44 inches above the floor. A 46 in sill exceeds the maximum, and 5.0 sq ft is short for an above-grade room. Options b, c, and d misstate or ignore the life-safety requirement.
