UN 1759 — Corrosive solid, n.o.s.
Placard: Corrosive. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1759 is Corrosive solid, n.o.s., a Class 8 not-otherwise-specified corrosive solid assigned to ERG Guide 154. The exact product controls water reactivity, dust hazard and cleanup method.
Hazard overview: UN 1759 presents corrosive dust, skin/eye burn and contaminated-runoff hazards. Because this is an n.o.s. entry, responders should use shipping papers and SDS to confirm incompatibilities before applying water or cleanup agents.
Response guidance: For a UN 1759 incident, responders should verify the product with shipping papers, package markings, SDS and ERG Guide 154. Establish incident command, isolate the area, stay upwind, prevent incompatible contact, control runoff and choose entry or fire-control actions based on monitoring, SDS and local SOP.
Firefighter training notes: Training for UN 1759 should emphasize n.o.s. identification, SDS verification, corrosive dust control, water-compatibility checks, PPE selection and runoff containment. Use ERG 154, SDS and local SOP.
Regulatory context: Corrosive solid, n.o.s. is regulated as a hazardous material for transportation and emergency response purposes. Transportation, workplace exposure, spill reporting, pesticide/waste handling where applicable, storage and environmental requirements may vary by formulation, concentration, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, facility documents and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Corrosive solid, n.o.s. should be stored in tightly closed compatible containers in a cool, dry, secure corrosive-material area away from incompatible chemicals, moisture where listed by SDS and unauthorized access. Prevent dust release and contaminated runoff.

PPE Requirements
Use positive-pressure SCBA for airborne dust, fire or confined-space exposure. Wear chemical-resistant gloves, eye/face protection and protective clothing selected from SDS for the specific solid.
Isolation & Evacuation
First Actions for a UN 1759 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Avoid breathing vapors, fumes, dust, mist or spray and avoid skin or eye contact.
- Do not touch or walk through spilled material unless properly trained and wearing appropriate protective equipment.
- Prevent product, dust, solution or runoff from reaching drains and waterways where practical.
- Ventilate closed spaces before entering, but only if properly trained, equipped, monitored and authorized by incident command.
- Isolate the spill or leak area and expand the perimeter if vapor, dust, fire involvement, water reaction or unknown concentration is present.
- Use ERG Guide 154, shipping papers, SDS, air monitoring and incident command for protective actions.
