UN 2430 Quick Details
UN 2430
Product name: Alkylphenols, solid, n.o.s. (including C2-C12 homologues)
DOT Class: 8
Placard type: Corrosive
ERG Guide: 153 (check current ERG)
Initial isolation: ERG 153: isolate spill area 25-50m; if tank/rail car involved in fire, isolate 800m all directions and consider evacuation
Common Hazards of UN 2430
- TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury
- Methyl bromoacetate (UN2643) is an eye irritant/lachrymator (causes flow of tears).
- Contact with molten substance may cause severe burns to skin and eyes.
- Avoid any skin contact.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental
- Combustible material: may burn but does not ignite readily.
- When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion
Chemical Identity & Physical Properties
| Also known as | alkyl phenolsphenol alkyl derivativesC2-C12 alkylated phenolssolid alkylphenols |
| Appearance | Solid material, typically white to tan crystalline or waxy substance at room temperature. May have a faint phenolic odor. |
| Flash Point | Varies by specific alkylphenol, typically 110-150C (230-302F) for solid forms |
| Boiling Point | Varies by homologue, typically 200-300C (392-572F) depending on alkyl chain length |
| Vapor Density | Not applicable at room temperature (solid); vapors heavier than air if heated |
| Water Reactivity | No significant reaction with water, but may slowly hydrolyze in alkaline conditions |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2430
Extinguishing Media
Alcohol-resistant foam, dry chemical, CO2; water spray may be used for cooling
PPE Requirements
⚠️ Level B minimum recommended; chemical-resistant gloves, boots, and apron required; SCBA for fire or confined space; avoid molten material contact
Isolation & Evacuation
ERG 153: isolate spill area 25-50m; if tank/rail car involved in fire, isolate 800m all directions and consider evacuation
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 153).
First Actions for a UN 2430 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 in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- 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
