Massachusetts Unrestricted Construction Supervisor License Practice Test

In a single-family dwelling, which of the following items does NOT require safety glazing?

1. Swinging doors

2. Storm doors

3. Jalousies

4. Railings

The correct answer is: Jalousies

Safety glazing is a requirement in certain situations to prevent injuries from broken glass in areas where it is more likely to occur. In the context of a single-family dwelling, safety glazing must be used in locations where human impact is a significant risk, such as near doors, windows, and other similar areas. Swinging doors and storm doors typically require safety glazing because they are at a height where a person could accidentally walk into them, creating a risk of injury from shattered glass. Jalousies, which are a type of window with adjustable horizontal slats that open for ventilation, are generally not subject to the same requirements for safety glazing in residential contexts. This is because their configuration and typical installation reduce the likelihood of impact injuries compared to doors. Railings also generally do not require safety glazing, since they are designed with materials intended to provide safety without the need for additional glazing materials. Therefore, among the items listed, jalousies are the correct answer as they do not typically require safety glazing.
