Claims
- 1. A fugitive color liquid fire retardant composition for aerial application to ground vegetation, said composition comprising:
a) fire retardant components including a fire retardant salt; b) a fugitive color component which improves the aerial visibility of said composition and which colors said composition to contrast with normal vegetation or ground; and c) a non-fugitive color component insoluble in an aqueous carrier which improves the aerial visibility of said composition, said non-fugitive color component provided in less than an amount which prevents said composition from fading to a neutral color which blends with normal vegetation or ground.
- 2. A concentrate composition for preparing the composition of claim 1 by dilution thereof with an aqueous carrier, comprising said fire retardant components and said color components.
- 3. The concentrate composition of claim 2 which is a dry composition.
- 4. The concentrate composition of claim 2 which is a liquid concentrate composition.
- 5. The composition of claim 1 in which said non-fugitive component is titanium dioxide.
- 6. The composition of claim 1 in which said non-fugitive component is red iron oxide.
- 7. The concentrate composition of claim 4 in which said fire retardant salt comprises a liquid ammonium polyphosphate and said non-fugitive component is red iron oxide.
- 8. A fugitive color liquid fire retardant composition for aerial application to ground vegetation, said composition comprising:
a) fire retardant components including a fire retardant salt; b) a fugitive color component which improves the aerial visibility of said composition and which colors said composition to contrast with normal vegetation or ground; and c) titanium dioxide provided in an amount sufficient to improve the aerial visibility of said composition, but said titanium dioxide provided in less than an amount which prevents said composition from fading to a neutral color which blends with normal vegetation or ground.
- 9. A method for fighting wildfires comprising the steps of:
applying a fire retardant composition to ground vegetation, which composition includes;
a) fire retardant components including a fire retardant salt; b) a fugitive color component which improves the aerial visibility of said composition and which colors said composition to contrast with the vegetation or ground; and c) a non-fugitive color component insoluble in an aqueous carrier which improves the aerial visibility of said composition, said non-fugitive color component provided in less than an amount which prevents said composition from fading to a neutral color which blends with the vegetation or ground.
- 10. The method of claim 9 wherein said non-fugitive color component includes titanium dioxide.
- 11. The method of claim 9 wherein said non-fugitive color component includes red iron oxide.
- 12. The method of claim 9 wherein said fire retardant salt comprises a liquid ammonium polyphosphate and said non-fugitive component is red iron oxide.
