Chemical Identity & Physical Properties
| Also known as | Environmental hazard solid NOSHazardous to aquatic environment solidMarine pollutant solidEcotoxic substance solid |
| Appearance | Variable appearance depending on specific substance; typically a solid material at room temperature that poses environmental hazards, particularly to aquatic ecosystems. May be powders, granules, or solid masses with varying colors and no characteristic odor as this is a generic classification. |
| Flash Point | Variable depending on specific substance; many are not readily ignitable |
| Boiling Point | Not applicable (solid at ambient conditions) |
| Vapor Density | Not applicable (solid material) |
| Water Reactivity | Generally no violent reaction, but may slowly dissolve or release harmful substances into water causing environmental damage |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 3077
Extinguishing Media
Dry chemical, CO2, water spray, or foam generally acceptable; specific agent depends on actual substance
PPE Requirements
⚠️ Level D minimum for routine handling; Level C or B if substance identity unknown or airborne exposure possible; nitrile or neoprene gloves recommended; respiratory protection if dust generation occurs
Isolation & Evacuation
ERG 171: Small spills isolate 25m all directions; large spills isolate 50m all directions; no evacuation distances specified for this guide as materials present minimal immediate hazard to people
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 171).
First Actions for a UN 3077 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
