🔍 Key Concepts

• Firefighting agents and their compatibility with different fuel types (especially glycols and alcohol-type liquids) • Differences between dry chemical, foam, and CO₂ as extinguishing media • Whether triethylene glycol behaves more like a polar solvent (water-miscible) or a typical hydrocarbon fuel

💭 Think About

• Think about what type of liquid triethylene glycol is: is it water-miscible like alcohol, or more like gasoline/diesel? • Which extinguishing agents are generally recommended for flammable liquid fires that can mix with water? • Is there any firefighting agent in the list that would not normally be effective or appropriate for this type of liquid fire?

✅ Before You Answer

• Verify whether alcohol foam is specifically designed for water-miscible (polar) liquids such as alcohols and glycols • Check if CO₂ is generally effective on flammable liquid fires in confined spaces but has limitations in open or ventilated areas • Confirm whether dry chemical is commonly rated for flammable liquid fires and compatible with this type of fuel
