Safety Trained Supervisor (STS) Practice Exam

Who is responsible for approving the use of a scaffold that is 20 feet high?

1. A project manager

2. A safety coordinator

3. A competent person

4. The site supervisor

The correct answer is: A competent person

The responsibility for approving the use of a scaffold that is 20 feet high lies with a competent person. A competent person is defined as someone who has the necessary knowledge, training, and experience to identify existing and predictable hazards in the surroundings or working conditions. They are authorized to take prompt corrective action to eliminate these hazards. In the context of scaffolding, the competent person must evaluate the setup, ensure compliance with safety regulations, and confirm that all practices are followed to protect workers from potential accidents. This evaluation is crucial because scaffolding can present significant risks if not properly installed and maintained, particularly at greater heights. While project managers, safety coordinators, and site supervisors each play important roles in overall safety management and coordination, the competent person's specialized expertise about scaffolding specifically is what makes them the designated authority to approve its use. They are trained to inspect the scaffold and confirm that it meets necessary safety standards before it is utilized.
