What is the timeframe for submitting a written report after a hazmat incident?

The correct answer reflects that a written report must be submitted within 30 days following a hazardous materials incident. This timeframe is crucial because it ensures that timely documentation is provided to authorities regarding the nature of the incident, any actions taken, and the overall impact. Such reports can play a key role in assessing the situation, investigating the causes, implementing safety measures, and preventing future occurrences. Additionally, adhering to this 30-day timeframe aligns with federal regulations aimed at maintaining safety standards and accountability in handling hazardous materials.

The other options reflect timeframes that are not compliant with the regulations, as they either provide too short or too long a period for reporting, which could hinder effective response and recovery efforts following a hazmat incident.
