If a basement bedroom window opens into a window-well, what clearance must be provided in front of the window?

• A. 60 centimetres (24 inches)
• B. 76 centimetres (22 inches)
• C. 90 centimetres (36 inches)
• D. 100 centimetres (40 inches)

Answer: (B)

The essential idea is that an egress window facing a window-well must have enough space in front of it so someone can safely exit and rescuers can access if needed. When a basement bedroom window opens into a window-well, clearance is required to allow the window to be opened fully and for a person to move from the opening into the well and onward to safety. The minimum front clearance specified is 76 centimetres (about 30 inches). This amount provides room for the occupant to exit without brushing against obstacles and gives space for rescue personnel or equipment to reach the window if necessary.

Choices offering less than this can block the escape route, while larger clearances go beyond the minimum requirement. So the required clearance is 76 cm (about 30 inches).
