UN 2710 — Dipropyl ketone

Placard: Flammable. ERG Guide 128. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.

🚒☣️
⚠️ 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.

Dipropyl ketone is a flammable ketone liquid. Vapors can move along the ground and ignite away from the spill area.

Hazard overview: Dipropyl ketone presents a flammable vapor hazard. Vapor can move along surfaces, enter drains or low spots and flash back to the spill or container.

Response guidance: Eliminate ignition sources, isolate the release and keep product out of sewers. Use Alcohol-resistant foam, dry chemical or CO2 for fire control, and cool exposed containers from a protected position.

Firefighter training notes: Train crews to identify Dipropyl ketone by UN number, placard, ERG guide and SDS before choosing entry, isolation or extinguishment tactics.

Regulatory context: Use UN 2710, ERG 128, SDS, container labels and shipping papers to confirm the exact hazard profile and protective action distances.

Storage & handling: Store in closed, compatible containers away from heat, ignition sources and incompatible materials; keep the area ventilated and protected from damage.

Common Hazards of UN 2710

  • Highly flammable liquid; vapors may ignite from heat, sparks, static or open flame.
  • Vapors can form explosive mixtures with air and travel to a distant ignition source.
  • Heavier-than-air vapors may collect in low areas, confined spaces, drains or sewers.
  • Runoff to drains can create fire or vapor explosion hazards.
  • Containers exposed to fire may rupture or explode from pressure buildup.
  • Liquid contact may irritate skin and eyes; inhalation may cause dizziness or respiratory irritation.
  • Fire may produce irritating or toxic smoke.

Isolation & Evacuation

ERG 128: Isolate spill 50m all directions; for large spill isolate 150m, evacuate 800m downwind if fire
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 128).

First Actions for a UN 2710 Incident

  • Call 911 and the emergency response number shown on shipping papers or container documents.
  • Keep unauthorized personnel away and establish an initial isolation perimeter.
  • Stay upwind, uphill and upstream; avoid low areas where vapors or runoff may collect.
  • Avoid breathing vapors, dust, smoke or mist and prevent skin and eye contact.
  • Eliminate ignition sources, stop traffic through vapor areas and keep product out of drains and sewers.
  • Do not touch damaged containers or spilled material without appropriate chemical PPE.
  • Ventilate confined spaces only when personnel are trained, monitored and properly equipped.
  • Use ERG guidance, SDS, shipping papers and air monitoring before committing crews.

Frequently Asked Questions about UN 2710

The main hazard is described by its flammable classification; responders should also check SDS details for the exact product.

Yes. Fire risk depends on the material: flammable liquids and solids can ignite, while oxidizers can intensify other fires.

Isolate the area, stay upwind, deny entry and verify the ERG guide, SDS and shipping papers before close approach.

Use SCBA when vapors, dust, smoke or unknown concentrations are present, with chemical-resistant clothing as the product requires.

Yes. Fire water or spill runoff may be contaminated, corrosive, toxic or capable of spreading the hazard.
