🔍 Key Concepts

• Check the typical fire-fighting recommendations for Propionitrile (a nitrile, flammable liquid) in the Emergency Response Guidebook or MSDS/SDS tables. • Think about how alcohol-resistant foam, water fog, carbon dioxide, and dry chemical behave on flammable liquid fires. • Consider whether water in any form might spread or react with this type of cargo.

💭 Think About

• Is Propionitrile treated more like an alcohol/polar solvent, a generic flammable liquid, or something that reacts with water? • For this chemical, do standard references recommend cooling containers with water, and if so, in what form (solid stream vs. fog/mist)? • Which agents are typically listed together as acceptable for flammable liquid chemical fires in Coast Guard/IMDG/ERG guidance?

✅ Before You Answer

• Verify whether solid streams of water are recommended or specifically not recommended for this cargo. • Confirm if alcohol foam is listed as suitable for this substance in standard chemical fire guides. • Check if both carbon dioxide and dry chemical are normally acceptable for small flammable liquid fires involving nitriles like Propionitrile.
