How should responders handle unknown containers with no visible labels?

• A. Treat as hazmat; isolate, establish zones, and consult ERG for identification cues.
• B. Ignore unlabeled containers and proceed.
• C. Open container to read contents.
• D. Move container to a secure area for later labeling.

Answer: (A)

Unknown containers with no labels pose a real risk because you don’t know what hazard they contain. The safest approach is to treat them as hazmat from the start: isolate the container to stop exposure and prevent spread, set up protective zones so responders and bystanders are kept at safe distances, and use the Emergency Response Guidebook to look for identification cues from visible features like shape, packaging, material, or any markings. The ERG will guide you to the right section for an unidentified item and tell you the initial actions to take, including PPE, evacuation needs, and isolation distances. Opening the container, reading contents, or moving it without proper assessment could unleash an unknown hazard, so those actions aren’t appropriate. Treat, isolate, establish zones, and consult the ERG for identification cues and next steps.
