Placard: Flammable. ERG Guide 132. 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.

Isopropylamine is a colorless liquid with a strong ammonia-like or fishy odor, commonly used as a solvent and cleaning agent. It is highly volatile and flammable at room temperature, making it a significant fire hazard if not handled properly.

Hazard overview: Isopropylamine is flammable and can be ignited by heat, sparks, or flames, and its vapors can cause respiratory irritation and other health issues. It also has corrosive properties, which can cause skin and eye irritation.

Response guidance: In case of a spill, evacuate the area immediately and use alcohol-resistant foam or other recommended extinguishing agents to prevent the fire from spreading. Emergency responders should wear Level B minimum protective equipment with SCBA and chemical-resistant gloves and suit due to its corrosive properties.

Common Hazards of UN 1221

  • Flammable/combustible material.
  • May be ignited by heat, sparks or flames.
  • Vapors may form explosive mixtures with air.
  • Vapors may travel to source of ignition and flash back.

PPE Requirements

⚠️ Level B minimum with SCBA required; chemical-resistant gloves and suit due to corrosive amine properties

Emergency responders should wear Level B minimum protective equipment with SCBA and chemical-resistant gloves and suit due to its corrosive properties.

Isolation & Evacuation

ERG 132: isolate spill 25-50m all directions; for large spill consider initial evacuation 300m downwind
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 132).

First Actions for a UN 1221 Incident

  • Keep unauthorized personnel away.
  • Stay upwind, uphill and/or upstream.
  • Ventilate closed spaces before entering, but only if properly trained and equipped.
  • Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
  • For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
  • For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
