🔍 Key Concepts

• Hazardous materials reporting requirements to the U.S. Department of Transportation (DOT) under 49 CFR • Difference between a reportable release vs. minor or exempt releases (e.g., residue, properly emptied containers) • Factors that trigger a detailed incident report: quantity, type of material, circumstances, and resulting damage or injury

💭 Think About

• For each choice, ask: Does this involve an actual release of hazardous material into the environment, or just residue/trace amounts? • Consider whether there is significant risk to safety, property, or the marine environment in each scenario. • Think about which scenario most closely resembles a normal handling or minor residue situation rather than a transportation incident.

✅ Before You Answer

• For each option, identify if there was damage, injury, or property/environmental harm. • Check whether the material released is from a loaded container vs. an empty/previously unloaded container with only residue. • Verify which situation would most likely be treated as a minor residue loss that does not trigger a detailed DOT incident report.
