UN 3244 — Solids containing corrosive liquid, n.o.s.
Placard: Corrosive. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 3244 is Solids containing corrosive liquid, n.o.s., a broad corrosive liquid-in-solid entry assigned to ERG Guide 154. Hidden free liquid and corrosive runoff are key hazards.
Hazard overview: CORROSIVE liquid absorbed or contained in solid material, n.o.s.; contact can burn eyes, skin and respiratory tissue. Damaged packages can leak corrosive liquid from absorbent, matrix or article contents. Solid carrier may hide the amount of free liquid present.
Response guidance: For UN 3244, isolate damaged packages, prevent leakage spread and use PPE for the contained liquid. Contain runoff and verify exact contents with SDS and ERG 154.
Firefighter training notes: Training for UN 3244 should emphasize product verification, SCBA use, dust/vapor control, decontamination, runoff containment and SDS/package review. Use ERG 154, SDS and local SOP.
Regulatory context: Solids containing corrosive liquid, n.o.s. is regulated as a hazardous material for transport and emergency response. Storage, reporting, exposure, waste and incident-notification duties depend on quantity, formulation, package type and jurisdiction; verify shipping papers, SDS and authority guidance.
Storage & handling: Solids containing corrosive liquid, n.o.s. should be stored in intact compatible packages with secondary containment, restricted access and segregation based on the contained liquid's SDS and incompatibilities.
UN 3244 Quick Details
Common Hazards of UN 3244
- CORROSIVE liquid absorbed or contained in solid material, n.o.s.; contact can burn eyes, skin and respiratory tissue.
- Damaged packages can leak corrosive liquid from absorbent, matrix or article contents.
- Solid carrier may hide the amount of free liquid present.
- Some contained liquids may react with metals, water or incompatible materials depending on identity.
- Fire may release corrosive/toxic smoke or acidic/alkaline runoff.
- Runoff may spread corrosive contamination.
- Exact corrosive liquid, pH, carrier and leakage potential must be verified from SDS and shipping papers.
Chemical Identity & Physical Properties

PPE Requirements
Use positive-pressure SCBA where mist, vapor, dust or fire is present. Wear chemical-resistant splash protection, gloves, boots and eye/face protection.
Isolation & Evacuation
First Actions for a UN 3244 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, spilled material or residue without proper training and PPE.
- Prevent contaminated runoff, dust, liquid and decontamination waste from spreading.
- Ventilate confined spaces only after monitoring and only if properly trained and equipped.
- Use ERG Guide 154, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
