Massachusetts Construction Supervisor License (CSL) Practice Test

Which of the following does not meet the emergency escape window requirements for a two family dwelling?

1. A window with a minimum opening of 22 in. x 20 in.

2. A window that requires a key for operation

3. A window located within a basement

4. A window that opens inward

The correct answer is: A window that requires a key for operation

The answer that does not meet the emergency escape window requirements for a two-family dwelling is a window that requires a key for operation. According to building codes, emergency escape windows must be operable without special tools, keys, or knowledge. This requirement is in place to ensure that occupants can quickly and easily exit the building in the event of an emergency, such as a fire. If a window is locked and requires a key to operate, it would pose a significant risk during an emergency, as it could impede escape. The other options may have characteristics that could still comply with escape requirements. For example, a window with specific dimensions may meet minimum size requirements for egress, and windows located within a basement may also satisfy certain conditions depending on their size and accessibility. Similarly, a window that opens inward, as long as it fulfills size and operational criteria, can still be classified as an emergency escape window. Thus, the critical aspect of accessibility and operability without special tools makes the window requiring a key the correct answer for not meeting emergency escape window requirements.
