UN 1267
Class: 3
Placard type: Flammable
ERG: Guide 128 (check current ERG)

Chemical & Response Details
| Also known as | Crude oilCrude petroleumPetroleumRock oilMineral oil (crude)Fossil oil |
| CAS Number | 8002-05-9 |
| Appearance | Dark brown to black viscous liquid with characteristic petroleum odor. Mixture of hydrocarbons with varying viscosity depending on source and composition. |
| Flash Point | -35°C to 32°C (-31°F to 90°F) depending on composition and vapor pressure |
| Boiling Point | Wide range 38°C to 400°C (100°F to 750°F) depending on hydrocarbon fractions present |
| Vapor Density | 3-4 (heavier than air) |
| Water Reactivity | No significant reaction with water. Floats on water surface and spreads rapidly. |
| Extinguishing | Alcohol-resistant AFFF foam, protein foam, CO2, dry chemical. Water spray for cooling only. |
| PPE | ⚠️ Level B minimum recommended. SCBA with full protective clothing. Splash-resistant chemical suit for spill control. Avoid skin contact due to carcinogenic components. |
| Isolation | ERG 128: Initial isolation 50m in all directions. For large spills isolate 100m. If tank/rail car involved in fire, isolate 800m in all directions and consider evacuation. |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- 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.
First actions (field-minded)
- 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).
