Abstract
A method and apparatus for classifying fire fighting foam is disclosed. Fire fighting foam analyzer 10 uses a large capacity container 11 having a viewing window 12 disposed in a substantially vertical wall 13. The viewing window 12 has thereon a volume scale 14 containing volume graduations and a ratio scale 15. To classify a foam by a foam type, fire fighting foam analyzer 10 is filled with an initial volume of foam, the initial volume is recorded, solution is allowed to separate from the foam for a given period of time, a final solution volume is recorded, the ratio of initial foam volume to final solution volume is determined and the ratio is correlated to a particular foam type by reading the ratio scale 15.
Claims5
A fire fighting foam analyzer which comprises:
- a multi-gallon capacity container of known volume having at least one vertical wall, for receiving fire fighting foam and determining initial foam to final solution ratios;
- and
- a transparent window disposed in said wall having a first visual indicia means thereon defining volume graduations for indicating the volumes of the initial foam and final solution within said multi-gallon capacity container at any particular level and further having a ratio to foam type correlating indicia thereon for correlating an initial foam to final solution ratio to a particular fire fighting foam type.
A method of classifying fire fighting foam by type using a multi-gallon capacity container of known volume having at least one generally vertical wall, for receiving fire fighting foam and determining initial foam to final solution ratios and a transparent window disposed in the wall having a first visual indicia means thereon defining volume graduations for indicating the volumes of the initial foam and final solution within said multi-gallon capacity container at any particular level, comprising the steps of:
- 1. filling said fire fighting foam analyzer with fire fighting foam;
- 2. reading said first visual indicia means to obtain an initial foam volume;
- 3. allowing solution to separate from the foam for a specified period of time;
- 4. reading said first visual indicia means to obtain a final solution volume;
- 5. defining a foam to solution ratio which is equal to the initial foam volume divided by the final solution volume;
- and
- 6. classifying the foam type by correlating the foam to solution ratio to a corresponding foam type.
A method for classifying fire fighting foam by type, comprising the steps of:
- 1. filling a container with a known volume of fire fighting foam;
- 2. allowing solution to separate from the foam for thirty minutes;
- 3. measuring the volume of the separated solution;
- 4. determining the ratio of foam to separated solution;
- and
- 5. identifying the foam type which corresponds to the determined ratio using the following chart:
- ______________________________________ FOAM RATIO TYPE RANGE ______________________________________ 1 23.5 and up 2 16.5 to 23.5 3 12 to 16.5 4 9.3 to 12 5 9.3 and below ______________________________________
A method for classifying fire fighting foam by type, comprising the steps of:
- 1. filling a container with a known volume of fire fighting foam;
- 2. allowing solution to separate from the foam for sixty minutes;
- 3. measuring the volume of the separated solution;
- 4. determining the ratio of foam to separated solution;
- and
- 5. identifying the foam type which corresponds to the determined ratio using the following chart:
- ______________________________________ FOAM RATIO TYPE RANGE ______________________________________ 1 22 and up 2 14.6 to 22 3 11 to 14.6 4 8.8 to 11 5 8.8 and below ______________________________________
