UN 1213 Quick Details
UN 1213
Product name: Isobutyl acetate
DOT Class: 3
Placard type: Flammable
ERG Guide: 129 (check current ERG)
Initial isolation: ERG 129: Small spill isolate 30m all directions; large spill isolate 150m and evacuate 800m downwind if fire
Common Hazards of UN 1213
- 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.
