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 At a Glance
UN 2430 (Alkylphenols, solid (including C2-C12 homologues)) is listed as DOT Class 8 Corrosive and is assigned to ERG Guide 153. Use this page to review placard data, common hazards, PPE notes, isolation context, first actions, and related UN numbers.
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.
