UN 1268 Quick Details
UN 1268
Product name: Petroleum distillates, n.o.s.
DOT Class: 3
Placard type: Flammable
ERG Guide: 128 (check current ERG)
Initial isolation: ERG 128: isolate spill 50m all directions; for large spills isolate 150m and evacuate 800m downwind if fire threatens
Common Hazards of UN 1268
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
- Vapors may travel to source of ignition and flash back.
- Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas
- Vapor explosion hazard indoors, outdoors or in sewers.
- Those substances designated with a (P) may polymerize explosively when heated or involved in a fire.
- Runoff to sewer may create fire or explosion hazard.
- Containers may explode when heated.
Chemical Identity & Physical Properties
| Also known as | petroleum distillatepetroleum naphthamineral spiritsStoddard solventpetroleum spiritsVM&P naphtha |
| Appearance | Clear to pale yellow or amber liquid with a characteristic petroleum or kerosene-like odor. Volatile flammable liquid at room temperature. |
| Flash Point | -18°C to 60°C (0°F to 140°F) depending on distillation range |
| Boiling Point | 150°C to 300°C (302°F to 572°F) typical range for petroleum distillates |
| Vapor Density | 3-5 (heavier than air) |
| Water Reactivity | No significant reaction with water; floats on water and forms a fire hazard layer |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 1268
Extinguishing Media
Alcohol-resistant AFFF foam, protein foam, CO2, dry chemical, or water spray for cooling
PPE Requirements
⚠️ Level B minimum; SCBA required in confined spaces or heavy vapor concentrations; chemical-resistant gloves and boots
Isolation & Evacuation
ERG 128: isolate spill 50m all directions; for large spills isolate 150m and evacuate 800m downwind if fire threatens
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 128).
First Actions for a UN 1268 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.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
- Consider initial downwind evacuation for at least 300 meters (1000 feet).
