2. storm doors

3. jalousies

4. railings

The correct answer is: jalousies

Safety glazing is a critical aspect in construction to ensure the safety of individuals in residential buildings. It refers to glazing materials that are designed to withstand impact and reduce the risk of injury from breaking glass. In a single-family dwelling, certain items are required to have safety glazing, particularly those that are at risk of being impacted or where people may easily come into contact with glass surfaces. Swinging doors and storm doors are potential points of contact for individuals, especially in high-traffic areas or when children are present. This makes safety glazing necessary for these types of doors to prevent injury from accidental collisions. Jalousies, which are typically louvered windows that can be opened for ventilation, also require safety glazing because they can pose a risk if broken, given their presence in areas where people may come into contact with them. Railings are designed to provide safety and are usually constructed from materials that do not require safety glazing; they’re primarily made from solid materials such as metal or wood. The structure and typical usage of railings mean that they are less likely to pose a risk associated with breakage and subsequent injury, allowing them to be exempt from the safety glazing requirement. Therefore, the item that does not require safety glazing in a single-family dwelling is jal
