||
| Fire-Trol 931-R is a wet concentrate formulation that uses ammonium polyphosphate (10-34-0) as the fire retardant salt. When mixed with water, the resulting retardant is unthickened (water-like). Fire-Trol 931-R contains a corrosion inhibitor and iron oxide color. Mixing occurs through simple proportioning of the retardant concentrate and water. The resulting mixed retardant is pumped directly into aircraft without intermediate storage. | ||
| Product Type: | Unthickened, liquid concentrate; demand-mixed. | |
| Qualification: | Conditionally qualified for use from a permanent or temporary base and can be applied from a fixed-wing airtanker or helicopter bucket. | |
| Use Level: | Approved for use in Canada only. 1 gallon of liquid concentrate mixed with 4.75 gallons of water will produce 5.71 gallons of mixed retardant. Each gallon of mixed retardant contains the equivalent of 2.08 pounds or 0.175 gallons of liquid concentrate | |
| Yield: | 1 ton of liquid concentrate yields 962 gallons of mixed retardant. | |
| Viscosity: | <50
centipoise (cP). Field measurement for the viscosity of the retardant mixed 4.75:1 is not meaningful; therefore, no data is provided for the mixed retardant. |
|
| Salt Content: | 7.25
percent by weight, P205 equivalent Field measurement (refractometer): A reading of 12.5 indicates a proper salt content. A reading between 11.25 and 13.75 indicates an acceptable salt content. |
|
| Specific Weight: | 9.00 and 11.88 lb/gal, respectively, for mixed retardant and liquid concentrate. | |
