Certified Treecare Safety Professional (CTSP) Practice Exam

How can struck-by hazards be minimized on a job site?

1. By ensuring workers wear reflective clothing

2. Through proper setup of cones, signs, and flags

3. By using heavier equipment to move materials

4. By providing personal safety devices to all workers

The correct answer is: Through proper setup of cones, signs, and flags

Minimizing struck-by hazards on a job site is critical for ensuring worker safety. The proper setup of cones, signs, and flags is an effective way to alert workers and operators about potential hazards, communicate restricted areas, and guide traffic flow. This creates a clear visual barrier and delineates work zones, helping to prevent accidents involving tools, machinery, or moving objects. When these indicators are correctly placed, they can significantly reduce the risk of workers being struck by vehicles or falling objects. While reflective clothing enhances visibility and is beneficial in certain situations, it does not directly control the risk of being struck. Similarly, providing personal safety devices is important for overall safety, but these devices alone do not address the environmental setup that can lead to struck-by hazards. Using heavier equipment to move materials might even increase the risk of accidents rather than mitigate them if not managed carefully. Therefore, focusing on the organization and communication through visible indicators is the most effective way to minimize struck-by risks on a job site.
