  • Patent number: 7341112
    Abstract: A firefighting training fluid (FFTF) comprising a paraffin blend. The blends of paraffins typically have no less than about two carbon atoms and no more than about twelve carbon atoms. The blends of paraffins may possess Reid vapor pressures in the range from about 2 to about 6.5 pounds per square inch. The blends also typically possess an initial boiling point of not less than about 80 degrees Fahrenheit and an end boiling point of not more than about 370 degrees Fahrenheit. The blends burn relatively cleanly and keep emissions of volatile organic compounds, compounds containing sulfur, smoke, particulates, olefins, and aromatics to a minimum. The blend components mixed to create the blends of paraffins are controlled in order to maintain Reid vapor pressure and initial and end boiling points. Oxygenates may be added to an FFTF in order to further reduce smoke emissions.

  • Publication number: 20040098906
    Abstract: A firefighting training fluid (FFTF) comprising an isoparaffin blend. The blends of isoparaffins typically have no less than about two carbon atoms and no more than about twelve carbon atoms. The blends of isoparaffins may possess Reid vapor pressures in the range from about 2 to about 6.5 pounds per square inch. The blends also typically possess an initial boiling point of not less than about 80 degrees Fahrenheit and an end boiling point of not more than about 370 degrees Fahrenheit. The blends burn relatively cleanly and keep emissions of volatile organic compounds, compounds containing sulfur, smoke, particulates, olefins, and aromatics to a minimum.
