UN 3536 — Lithium batteries installed in cargo transport unit (lithium metal batteries)

Placard: Miscellaneous. ERG Guide 138. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.

🚒☣️
⚠️ Verification required: Broad or variable material category; verify exact product, SDS and shipping papers.
⚠️ 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 3536 is Lithium batteries installed in cargo transport unit (lithium metal batteries), a lithium metal battery cargo unit entry assigned to ERG Guide 138. Thermal runaway and re-ignition are key concerns.

Hazard overview: Cargo transport unit containing installed lithium metal batteries; damaged cells can enter thermal runaway. Fire may produce flammable gases, toxic smoke and corrosive fluoride-containing vapors. Batteries inside a container or unit may hide damaged cells and delay visible fire signs.

Response guidance: For UN 3536, isolate the cargo unit, use SCBA for smoke and cool exposures. Expect re-ignition, hidden cells and difficult access; follow ERG 138/local SOP.

Firefighter training notes: Training for UN 3536 should emphasize thermal runaway, container access limits, re-ignition monitoring, smoke toxicity, water-cooling decisions and runoff control. Use ERG 138 and local SOP.

Regulatory context: Lithium batteries installed in cargo transport unit (lithium metal batteries) is regulated as a hazardous material for transport and emergency response. Storage, reporting, exposure, waste and incident-notification duties depend on quantity, package type, gas identity and jurisdiction; verify shipping papers, SDS and authority guidance.

Storage & handling: Lithium batteries installed in cargo transport unit (lithium metal batteries) should be stored to prevent short circuits, crushing, heat exposure and water damage, with damaged units isolated and fire response access maintained.

Common Hazards of UN 3536

  • Cargo transport unit containing installed lithium metal batteries; damaged cells can enter thermal runaway.
  • Fire may produce flammable gases, toxic smoke and corrosive fluoride-containing vapors.
  • Batteries inside a container or unit may hide damaged cells and delay visible fire signs.
  • Cells may vent, rupture, eject burning material or re-ignite after apparent extinguishment.
  • Large battery quantities can create difficult cooling and access problems.
  • Runoff may carry electrolyte, metal and burned packaging contamination.
  • Electrical hazards and short circuits may remain until the unit is isolated and stabilized.

Fireground Response Guidance — UN 3536

Extinguishing Media

Use large amounts of water for cooling/exposure protection when safe, or battery-appropriate agents per local SOP. Monitor for re-ignition and contain runoff.

PPE Requirements

⚠️ Level B minimum for intact units; Level A with SCBA if batteries are damaged, leaking, or on fire. Thermal protective gear for fire suppression.

Use SCBA for smoke/fire and full protective clothing. Chemical-resistant gloves and eye protection are needed for leaking electrolyte or damaged cells.

Isolation & Evacuation

ERG 138: Isolate spill area 25m in all directions. For large spills consider initial evacuation 100m. If fire or cargo on fire, isolate 800m and evacuate downwind 1600m.
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 138).

First Actions for a UN 3536 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.
  • Keep damaged or burning battery equipment away from combustibles when safe and monitor for re-ignition.
  • Avoid breathing vapor, gas, dust, mist, smoke or fumes and avoid skin or eye contact.
  • Do not touch damaged containers, equipment, articles or spilled material without proper training and PPE.
  • Prevent contaminated liquid, dust, runoff and decontamination waste from spreading.
  • Ventilate confined spaces only after monitoring and only if properly trained and equipped.
  • Use ERG Guide 138, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
