UN 1210 Quick Details
UN 1210
Product name: Printing ink related material, flammable
DOT Class: 3
Placard type: Flammable
ERG Guide: 129 (check current ERG)
Initial isolation: ERG 129: Initial isolation 50m in all directions; for large spill isolate 150m in all directions; if tank/rail car involved in fire isolate 800m in all directions
Common Hazards of UN 1210
- 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 | Printing inkInk related compoundFlammable printing ink mixtureInk solvent mixturePrinting ink thinner |
| Appearance | Variable appearance depending on formulation; typically colored liquid (black, cyan, magenta, yellow, or other colors) with characteristic solvent odor. May range from thin to viscous consistency at room temperature. |
| Flash Point | Below 23C (73F) - typically ranges from -4C to 23C (25F to 73F) depending on solvent composition |
| Boiling Point | Variable, typically 50-150C (122-302F) depending on solvent mixture; initial boiling point may be lower for volatile components |
| Vapor Density | Heavier than air (>1) - vapors will settle in low areas and confined spaces |
| Water Reactivity | No significant reaction with water, but insoluble and will float on water surface |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 1210
Extinguishing Media
Alcohol-resistant AFFF foam recommended; also CO2, dry chemical, water fog for cooling; avoid direct water stream
PPE Requirements
⚠️ Level B minimum for spill response; SCBA and chemical-resistant suit required for fire or large spills; nitrile or neoprene gloves for skin protection; organic vapor respirator minimum for small spills in ventilated areas
Isolation & Evacuation
ERG 129: Initial isolation 50m in all directions; for large spill isolate 150m in all directions; if tank/rail car involved in fire isolate 800m in all directions
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 129).
First Actions for a UN 1210 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).
