UN 2430 — Alkylphenols, solid, n.o.s. (including C2-C12 homologues)
Placard: Corrosive. ERG Guide 153. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2430 is Alkylphenols, solid, n.o.s. (including C2-C12 homologues), a broad corrosive/toxic phenolic solid category assigned to ERG Guide 153. Exact homologue and SDS must be verified.
Hazard overview: TOXIC and CORROSIVE alkylphenol solid; inhalation, ingestion or skin contact may cause severe injury. Phenolic material may be absorbed through skin and contaminated clothing. Combustible solid: may burn but does not ignite readily.
Response guidance: For UN 2430, isolate the area, avoid skin contact and use SCBA where dust, vapor, mist or fire is present. Contain toxic/corrosive runoff and verify exact product controls with SDS and ERG 153.
Firefighter training notes: Training for UN 2430 should emphasize toxic/corrosive exposure routes, skin absorption, SCBA use, decontamination, runoff containment and SDS verification. Use ERG 153, SDS and local SOP.
Regulatory context: Alkylphenols, solid, n.o.s. (including C2-C12 homologues) is regulated as a hazardous material for transport and emergency response. Storage, exposure, spill reporting, waste and fire-code duties depend on quantity, concentration and jurisdiction; verify shipping papers, SDS and local authority requirements.
Storage & handling: Alkylphenols, solid, n.o.s. (including C2-C12 homologues) should be stored in tightly closed compatible containers in a secure toxic/corrosive-material area with ventilation, secondary containment, restricted access and SDS-based segregation.
UN 2430 Quick Details
Common Hazards of UN 2430
- TOXIC and CORROSIVE alkylphenol solid; inhalation, ingestion or skin contact may cause severe injury.
- Phenolic material may be absorbed through skin and contaminated clothing.
- Combustible solid: may burn but does not ignite readily.
- Molten material can cause severe thermal and chemical burns.
- Fire may produce phenolic smoke, carbon monoxide and other toxic gases.
- Runoff may be corrosive/toxic and harmful to waterways.
- Exact toxicity and physical behavior vary by homologue; verify SDS.
Chemical Identity & Physical Properties
Solid material, typically white to tan crystalline or waxy substance at room temperature. May have a faint phenolic odor.
| 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 |

PPE Requirements
Use positive-pressure SCBA for dust, vapor, mist, fire or confined-space exposure. Wear chemical-resistant gloves, boots, eye/face protection and clothing; avoid skin contact.
Isolation & Evacuation
First Actions for a UN 2430 Incident
- Call 911 and the emergency response number on the shipping paper, if available.
- Keep unauthorized personnel away and establish incident command.
- Stay upwind, uphill and upstream.
- Avoid breathing vapor, dust, mist, smoke or fumes and avoid skin or eye contact.
- Do not touch damaged containers or spilled material without proper training and PPE.
- Prevent contaminated dust, liquid, runoff and decontamination waste from spreading.
- Ventilate confined spaces only after monitoring and only if properly trained and equipped.
- Use ERG Guide 153, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
