UN 1133
Class: 3
Placard type: Flammable
ERG: Guide 128 (check current ERG)
Isolation: ERG 128: Initial isolation 50m in all directions; protect from ignition sources; for large spills isolate 150m downwind
Chemical & Response Details
| Also known as | Flammable adhesiveCement (flammable)Glue (flammable)Contact adhesiveRubber cementModel glue |
| Appearance | Varies widely; typically clear to amber liquid or viscous paste with characteristic solvent odor (acetone, toluene, or other organic solvents). Some formulations may be gel-like or semi-solid. |
| Flash Point | Varies by formulation; typically -18°C to 23°C (0°F to 73°F) for highly flammable adhesives |
| Boiling Point | Varies by solvent composition; typically 56°C to 110°C (133°F to 230°F) depending on volatile components |
| Vapor Density | 2-4 (heavier than air for most solvent-based adhesives) |
| Water Reactivity | No significant reaction with water; may be immiscible and float on water surface |
| Extinguishing | Alcohol-resistant foam (AR-AFFF), CO2, dry chemical; water spray for cooling only |
| PPE | ⚠️ Level B minimum; SCBA required in confined spaces or heavy vapor concentrations; chemical-resistant gloves and suit recommended |
| Isolation | ERG 128: Initial isolation 50m in all directions; protect from ignition sources; for large spills isolate 150m downwind |
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).
