In the event that a hazmat incident should occur while in transit, a Hazardous Materials Incident Report must be filed at the time the incident is discovered. Reporting requirements apply whenever any of the conditions in CFR 171.16 are met. Found in 171.16, a completed DOT Form F5800.1 must be submitted within 30 days of the discovery of the incident. Those incidents that qualify for reporting are specified in CFR 171.15(b) and are defined as unintentional releases of a hazardous material or the discharge of any quantity of hazardous waste. Shippers should be familiar with these two regulations before a hazmat shipment becomes in-transit.
