🚒☣️
⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.

UN 1287 is Rubber solution, a flammable formulated liquid assigned to ERG Guide 127. Because formulations vary, responders should check SDS for solvent content, additive hazards and foam compatibility.

Hazard overview: UN 1287 presents flammable solvent vapor, flashback and contaminated-runoff hazards. Resins, pigments, rubber, alcohols or solvent blends can vary, so toxicity and fire-control choices should be confirmed from product documents.

Response guidance: For a UN 1287 incident, responders should confirm the product using shipping papers, container markings, SDS and ERG Guide 127. Establish incident command, isolate the area, stay upwind and uphill, remove ignition sources when safe, keep vapors or runoff out of sewers and use compatible fire-control agents from a protected position.

Firefighter training notes: Training for UN 1287 should emphasize formulation variability, vapor travel, flashback, sewer explosion risk, foam compatibility and SDS verification. Common errors include assuming all paints/inks/rubber solutions use the same solvent blend and allowing contaminated runoff into drains.

Regulatory context: Rubber solution is regulated as a hazardous material for transportation and emergency response purposes. Transportation, workplace exposure, spill reporting, waste handling, storage and environmental requirements may vary by formulation, 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: Rubber solution should be stored in tightly closed compatible containers in a cool, dry, well-ventilated flammable-liquid storage area. Keep away from heat, sparks, open flames, oxidizers and incompatible materials, with bonding/grounding, secondary containment and drain protection where required.

UN 1287 Quick Details

UN 1287
Product name: Rubber solution
DOT Class: 3
Placard type: Flammable
ERG Guide: 127 (check current ERG)
Initial isolation: ERG 127: Initial isolation 50m in all directions. Spill: evacuate 300m downwind. Large fire: evacuate 800m radius.

Common Hazards of UN 1287

  • FLAMMABLE formulation; exact solvent and additive hazards vary by product.
  • Vapors may form explosive mixtures with air and flash back to the source.
  • Most vapors are heavier than air and may spread into low, confined or sewer areas.
  • Pigments, resins, rubber, alcohols or other additives may change toxicity, runoff and foam compatibility.
  • Liquid may float, spread or form layers depending on formulation.
  • Fire may produce irritating or toxic smoke.
  • Containers may rupture or explode when heated.

Chemical Identity & Physical Properties

Clear to amber viscous liquid with a characteristic solvent odor. Contains natural or synthetic rubber dissolved in flammable solvents such as hexane, heptane, or petroleum naphtha.

Also known asRubber cementRubber adhesiveElastomer solutionLatex cement solution
AppearanceClear to amber viscous liquid with a characteristic solvent odor. Contains natural or synthetic rubber dissolved in flammable solvents such as hexane, heptane, or petroleum naphtha.
Flash Point-18C to 7C (0F to 45F) depending on solvent composition
Boiling Point60C to 120C (140F to 248F) depending on solvent mixture
Vapor Density3.0 to 4.0 (heavier than air, vapors will accumulate in low areas)
Water ReactivityNo significant reaction with water, but insoluble. Product will float on water surface.
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.

Fireground Response Guidance — UN 1287

Extinguishing Media

Use alcohol-resistant foam, AFFF where compatible, dry chemical or CO2 based on the formulation and SDS; water spray may cool containers but can spread some liquids.

PPE Requirements

⚠️ Level B minimum with SCBA required in enclosed spaces or high vapor concentrations. Chemical-resistant gloves and suit. Ensure adequate ventilation.

Use positive-pressure SCBA for fire, heavy vapor or confined-space exposure. Chemical-resistant gloves, splash protection and protective clothing should be selected from SDS; avoid skin contact with liquid and contaminated runoff.

Isolation & Evacuation

ERG 127: Initial isolation 50m in all directions. Spill: evacuate 300m downwind. Large fire: evacuate 800m radius.
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 127).

First Actions for a UN 1287 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.
  • Eliminate ignition sources if it is safe to do so.
  • Do not touch or walk through spilled liquid unless properly trained and wearing appropriate protective equipment.
  • Ventilate closed spaces before entering, but only if properly trained, equipped and authorized by incident command.
  • Identify the specific formulation from labels or SDS before choosing foam, decontamination or runoff controls.
  • Isolate the spill or leak area for at least 50 meters (150 feet) in all directions.
  • For large spills, fire involvement or strong vapor movement, expand isolation and consider downwind evacuation based on monitoring and incident command.
  • Use ERG Guide 127, shipping papers, SDS and local SOP for protective actions and entry decisions.
