Product Name: FSI-Defend (Containment Line)

This is a protective bushfire product based on a unique environmentally friendly long term fire retardant formula.  FSI-Defend is supplied as a powder which can be mixed with 1:10 to 1:15 (FSI-Defend powder to water) depending upon the required strength of the containment line.  Salt, brackish and fresh water can be used in this mix.  The mixed product can then sprayed on all types of vegetation to provide protection against an encroaching fire front.  It is coloured either yellow or red to help fire fighters seen where it has been sprayed.  The product can be used by property owners, farmers and rural fire fighters since it is easy to use, non-toxic and safe for the environment.  It has been designed to be one of the most environmentally friendly long term fire retardants in the world and will remain effective for more than 2 weeks if not rained on.
