What is the maximum sill height for a window meant for emergency rescue measured in inches?

The maximum sill height for a window intended for emergency rescue is crucial for safety regulations. Specifically, it is set to ensure that occupants can easily escape in case of a fire or emergency, or that emergency responders can gain access.

According to the International Residential Code (IRC), the maximum height of the window sill from the floor should not exceed 44 inches. This height allows for sufficient access while still maintaining structural integrity and design requirements for windows. In contrast, other heights listed in the options exceed this safety standard and are not permitted for rescue windows. This regulation is designed to ensure that escape routes are both accessible and safe, further supporting the importance of operational emergency exits in residential buildings.
