🚒☣️
⚠️ 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.
Zinc nitrate is a highly reactive substance used in various industrial applications. It is essential to handle this substance with caution to prevent accidents.
Hazard overview: Zinc nitrate can accelerate burning in fires and may decompose explosively when heated or involved in a fire. It is also a deliquescent substance that absorbs moisture from the air.
Response guidance: In case of a fire, use water spray to cool containers and dry chemical or CO2 for surrounding fires. Avoid using organic materials near the fire.

PPE Requirements
⚠️ Level B minimum recommended; full protective clothing, chemical-resistant gloves, face shield, and SCBA required during fire or spill response
Level B minimum recommended; full protective clothing, chemical-resistant gloves, face shield, and SCBA required during fire or spill response.
Isolation & Evacuation
ERG 140: isolate spill/leak area immediately for at least 25-50 meters in all directions; if tank/rail car involved in fire, isolate 800 meters in all directions and consider initial evacuation for 800 meters
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 140).
First Actions for a UN 1514 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 in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- Consider initial downwind evacuation for at least 100 meters (330 feet).
