UN 1986
Class: 3
Placard type: Flammable
ERG: Guide 131 (check current ERG)
Isolation: ERG 131: Small spill isolate 50m; large spill isolate 800m and evacuate 800m downwind initially
Chemical & Response Details
| Also known as | Flammable toxic alcoholsPoisonous alcohol mixturesToxic alcohol solutionsFlammable alcohol blends n.o.s. |
| Appearance | Variable depending on specific alcohol(s); typically clear to colored liquids with characteristic alcohol odor. Most are mobile liquids at room temperature with varying degrees of toxicity. |
| Flash Point | Varies by composition; typically below 23°C (73°F) as Class 3 flammable liquid |
| Boiling Point | Varies by specific alcohol mixture; typically 60-200°C (140-392°F) range |
| Vapor Density | Generally greater than 1 (heavier than air); specific gravity varies by alcohol type |
| Water Reactivity | Most alcohols are miscible or soluble in water; no violent reaction expected |
| Extinguishing | Alcohol-resistant (AR-AFFF) foam required; dry chemical, CO2 also effective |
| PPE | ⚠️ Level B minimum with SCBA required; butyl rubber or nitrile gloves; face shield; severe toxicity hazard requires full body protection |
| Isolation | ERG 131: Small spill isolate 50m; large spill isolate 800m and evacuate 800m downwind initially |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- TOXIC; may be fatal if inhaled, ingested or absorbed through skin.
- Inhalation or contact with some of these materials will irritate or burn skin and eyes.
- Methyl chloroacetate (UN2295) is an eye irritant/lachrymator (causes flow of tears).
- Fire will produce irritating, corrosive and/or toxic gases.
- Vapors may cause dizziness or asphyxiation, especially when in closed or confined areas.
- Runoff from fire control or dilution water may cause environmental contamination.
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
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.
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
