Isopropanol

If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, dry chemical or carbon dioxide.

Do not use a solid (straight) water stream as it may scatter and spread fire. /Isopropyl Alcohol, Reagent, ACS/
