Massachusetts Unrestricted Construction Supervisor License Practice Test

To determine if a double hung window provides an adequate clear opening for emergency escape in a two-family dwelling, it's essential to refer to the code requirements for egress windows. The minimum clear opening requirements for emergency escape and rescue windows as stated in the code typically require a minimum width of 24 inches and a minimum height of 24 inches, with a minimum net clear opening of 5.7 square feet.

In this case, while the window measurement of 22 inches by 20 inches may provide a decent size, it falls below the required minimum dimensions for width and height, thus failing to sufficiently meet the criteria for an emergency escape window. Therefore, the window does not meet the necessary building codes for egress requirements in a situation where immediate escape is needed. The other choices regarding tempered glass or screens are irrelevant in this context because the primary issue is with the dimensions of the window itself.
