Proportioning Information

Use between the following proportions:

  • Helicopter buckets: 0.3 - 0.6% (between 3-6 parts foam concentrate to 997-994 parts water)
  • Handline air-aspirating nozzles: 0.3 - 0.5% (between 3-5 parts foam concentrate to 997-995 parts water)
  • Handline non-air-aspirating nozzles: 0.3 - 0.6% (between 3-6 parts foam concentrate to 997-994 parts water)
  • Compressed Air Foam Systems (CAFS): 0.1 - 0.3% (between 1-3 parts foam concentrate to 999-997 parts water)
  • Use in fire breaks or small hydrocarbon fires: 1.0% (1 part foam concentrate to 99 parts water)

Proportioning rates will vary depending on the quality of the foam blanket required and are given for guidance only.
