Within how many hours should the DNR and local emergency response agencies be notified after a chemical spill?

• A. Immediately
• B. After cleanup
• C. Within 24 hours
• D. Within 72 hours

Answer: (C)

Spill reporting to the DNR and local emergency response agencies must occur within 24 hours of discovery. This time frame ensures authorities can quickly assess the situation, contain the release, and coordinate a proper response to protect the environment and public health. You should act immediately to stop the spill and secure the area, and call local emergency services if there’s an imminent danger. Reporting after cleanup would miss the opportunity for timely intervention, and waiting longer than 24 hours could allow the spill to worsen, which is why the official requirement is within 24 hours.
