The standard building procedures already follow this regulation, so children can still climb out of the egress window without any problems. An egress window must be at least 20 inches wide and 24 inches high with openings of at least 5.7 square feet, and sills shall not exceed 44 inches in height to qualify for the minimum requirement of escape emergency escape. If it fails to comply with these regulations, then egress window installation will have to be done again.
