1. What is the role of the Safety Trained Supervisor Construction (STSC) in post-incident investigation?

   • A. To assign disciplinary action to involved workers
   • B. To secure the scene, document conditions, and identify root causes to prevent recurrence
   • C. To negotiate with OSHA on behalf of the company
   • D. To process workers' compensation claims

Answer: B. To secure the scene, document conditions, and identify root causes to prevent recurrence

The STSC's role in post-incident investigation is to preserve the scene, gather facts, and conduct root cause analysis to prevent future incidents.

Answer: B. Recognize that correcting unsafe behavior is a core supervisory responsibility regardless of worker seniority

All workers must be held to the same safety standards, and supervisors must address violations regardless of a worker's experience or tenure.

Answer: B. Number of safety observations and near-miss reports submitted.

Leading indicators are proactive, forward-looking measures that track activities designed to prevent incidents. The number of safety observations and near-miss reports is a leading indicator because it reflects active employee engagement in identifying hazards before they cause an accident. TRIR, DART rate, and compensation costs are all lagging indicators, as they measure past incidents and outcomes.

Answer: B. Identify why workers are bypassing the guardrail before imposing penalties

Understanding the root cause of unsafe behavior (e.g., inconvenience, poor placement) is the first step in effective risk assessment to create lasting corrective action.
