On scaffolding, what is the minimum width that platforms or walkways can be before fall protection is required?

1. 12 inches

2. 18 inches

3. 24 inches

4. 36 inches

The correct answer is: 18 inches

In the context of scaffolding safety regulations, a key requirement is related to the width of platforms and walkways. Fall protection is mandated to ensure worker safety when working at heights. According to OSHA guidelines, if the width of a scaffolding platform or walkway is less than 18 inches, fall protection systems must be implemented at all times. The rationale behind this specific measurement is largely based on the increased risk of falls over narrower surfaces, significantly if workers are required to move or carry materials while on these platforms. By establishing 18 inches as the threshold, safety regulations strive to minimize the risk by ensuring that workers have adequate space to balance and maneuver without an imminent risk of falling over the edge. Platforms that are 18 inches wide or more provide a more stable base for workers, thereby reducing the necessity for active fall protection measures, although some safety practices should still be utilized for any elevated work. This is why the choice indicating 18 inches is recognized as the correct response regarding the minimum width before fall protection is required.
