Oil and fat fire; Category F
Another unique PU 1 application is the way of extinguishing a category F fire.
Start spreading the mix in small quantities far above the fire. The mix will created this aerosol from top/down and will extinguish fires of this nature.
9) Professional fire fighter with a small pan and a bucket of mix in action to make a successful attempt
10) With repeatedly using quantities of 20-30 centiliter of mix per throw, the fire begins to lose strength
11) After less then 1 minute and the total use of 3,5 liter of mix, the fire is under control.
12) The other uniqueness of the mix is that it will prevent the source from re-ignition as seen on picture 12. At all times the smoke remains transparent. Watch the fire extinguish equipment; bucket and little pan in the hand of the fire fighter.
