Chemical Identity & Physical Properties
| Also known as | Environmentally hazardous substance liquid NOSMarine pollutant liquidAquatic pollutant liquidHazardous to the environment liquid |
| Appearance | Physical properties vary widely as this is a generic classification for liquid substances harmful to aquatic environments. Typically colorless to colored liquids at room temperature with varying odors depending on the specific substance. |
| Flash Point | Varies by specific substance; generally not readily ignitable |
| Boiling Point | Varies by specific substance |
| Vapor Density | Varies by specific substance |
| Water Reactivity | Generally no significant reaction with water, though environmental contamination is a concern |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 3082
Extinguishing Media
Foam, dry chemical, CO2, or water spray typically suitable; avoid release to environment
PPE Requirements
⚠️ Level D minimum for routine handling; upgrade to Level C or B if substance identity unknown or airborne exposure risk exists; chemical-resistant gloves and eye protection required
Isolation & Evacuation
ERG 171: No evacuation distances specified for small spills; isolate immediate area and prevent environmental release; for large spills isolate 25m in all directions
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 171).
First Actions for a UN 3082 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
