• Chemical Data Guide for Bulk Shipment by Water tables for fire and explosion hazards • Differences between water spray, CO2, dry chemical, and foam on chemical/liquid fires • How certain agents can spread or react with burning liquids or chemicals

💭 Think About

• Is retinol treated more like a flammable liquid, a reactive chemical, or something else in the Guide? • Which extinguishing agents can cause spreading of burning liquid or be ineffective on certain chemical fires? • For cargo chemicals, does the Guide ever warn that a particular agent is not recommended because of reactivity or behavior on the liquid surface?

✅ Before You Answer

• Look up retinol in the Chemical Data Guide and read the specific line under the Fire and Explosion Hazard and Firefighting sections • Check which agents are listed as suitable or recommended, then note if any is specifically stated as not recommended or omitted • Confirm if any agent (especially foam vs water spray) might worsen a spill fire or have limited effectiveness on that class of chemical
