What is the red stuff that is used to extinguish fires from planes, called "fire delaying"?
I found This List, but I can't cross reference to which material is used.
Hi,
You were almost there with that list
There are three kinds of fire retardants in common use today :
Ammonium Sulfate, Polyphosphate and diammonium phosphate.
Thank you very much!
Do you maybe also know HOW these agents delay the fire?
