Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

What does a door stop do?

1. Forms the sides of a door opening

2. Supports a run of handrail on a stairway

3. Acts as a small strip around the doorjamb that the door closes against

4. Separates adjacent door or window sections

The correct answer is: Acts as a small strip around the doorjamb that the door closes against

A door stop plays a crucial role in the functionality and efficiency of a door by serving as a small strip around the doorjamb that the door closes against. This component helps to prevent the door from swinging too far open or closed, thereby minimizing the potential for damage to the wall or the door edge itself. It creates a barrier that ensures the door can close securely and fit properly within its frame. This functionality is especially important in preventing drafts and providing a seal that contributes to energy efficiency within a building. Additionally, when doors are closed, the door stop helps to absorb some of the force of the closing action, which can protect both the door and its frame from wear and tear over time. Understanding this function is key, particularly in contexts involving older buildings where lead-based paint may be present. Ensuring that doors operate smoothly with proper stops can help assess and maintain safe environments within such structures.
