Quick details
UN 2059
Class: 3
Placard type: Flammable
ERG: Guide 127 (check current ERG)
Isolation: ERG 127: isolate spill area minimum 50m all directions; for large spills isolate 800m downwind; evacuate immediate area if fire involves bulk containers
Chemical & Response Details
| Also known as | CollodionCellulose nitrate solutionNitrocellulose in solventPyroxylin solutionGun cotton solution |
| Appearance | Clear to pale yellow viscous liquid with a characteristic ether-like or solvent odor. The solution contains nitrocellulose dissolved in flammable organic solvents such as alcohols, esters, or ketones. |
| Flash Point | -18C to 13C (0F to 55F) depending on solvent composition |
| Boiling Point | 35C to 82C (95F to 180F) depending on solvent mixture |
| Vapor Density | 2-3 (heavier than air, varies with solvent) |
| Water Reactivity | No significant reaction with water, but insoluble and will separate as a layer |
| Extinguishing | Alcohol-resistant foam (AR-AFFF), CO2, dry chemical powder; regular AFFF may be ineffective due to alcohol solvents |
| PPE | ⚠️ Level B minimum with SCBA required; butyl rubber or nitrile gloves; fire-resistant suit for fire conditions; explosive potential requires safe distance |
| Isolation | ERG 127: isolate spill area minimum 50m all directions; for large spills isolate 800m downwind; evacuate immediate area if fire involves bulk containers |
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).
