Acetonitrile

Foam, carbon dioxide, dry chemical

Stay upwind and use water spray to knock down vapor.

Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Use water spray, dry chemical, "alcohol resistant" foam, or carbon dioxide. Use water spray to keep fire-exposed containers cool.

Advice for firefighters: wear self contained breathing apparatus for fire fighting if necessary.

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.

Evacuation: If fire becomes uncontrollable or container is exposed to direct flame-consider evacuation of one-third (1/3) mile radius.

Water may be ineffective. Alcohol foam.
