OSHA 30 Hour Construction Program Practice Test

Which three elements are usually associated with struck-by accidents?

1. Vehicles, falling objects, masonry walls

2. Tools, ladders, weather conditions

3. Heavy machinery, scaffolding, and manual lifting

4. Electrical hazards, ground conditions, and noise levels

The correct answer is: Vehicles, falling objects, masonry walls

Struck-by accidents are a significant concern in the construction industry and are often characterized by specific elements that lead to these incidents. The correct answer highlights elements that are commonly associated with the risks of being struck by an object or vehicle on a work site. The presence of vehicles, falling objects, and masonry walls all contribute to the likelihood of struck-by accidents. Vehicles, such as trucks and construction equipment, can inadvertently strike workers when they are in motion or not clearly seen. Falling objects, such as tools, materials, or debris, can pose a serious risk if not properly secured or if work is performed at height without adequate protection. Masonry walls, particularly those that are being constructed or demolished, can collapse or have materials that fall from them, creating hazards for workers in close proximity. In contrast, the other options mention factors that are less directly linked to the struck-by category. While tools and ladders (from the second choice) involve safety considerations, they are not the primary causes of struck-by incidents. Heavy machinery and manual lifting (described in the third choice) relate more to caught-in or caught-between hazards. The final option refers to environmental factors that, while important for overall safety, do not specifically pertain to the mechanisms of struck
