What does NIOSH investigate in the firefighting context?

• A. Equipment maintenance issues
• B. Medical insurance fraud
• C. Building codes and enforcement
• D. Firefighter line-of-duty deaths as part of its fatality assessment and control evaluation program

Answer: (D)

NIOSH’s firefighting investigations focus on line-of-duty fatalities to prevent future deaths. In firefighting, they run the Fatality Assessment and Control Evaluation program to examine each death, identify the circumstances and contributing factors, and make practical recommendations to improve training, procedures, PPE use, incident management, and policies. The goal is to learn from what happened and prevent similar fatalities in the future. Medical insurance fraud and building code enforcement are not part of this program, and while equipment issues can appear as factors in a fatality investigation, the emphasis is on understanding and stopping fatal incidents through prevention.
