Is SmartCoolant flammable?

The SmartCoolant is inherently non-flammable. The fire point of the fluid is 174 °C as measured by ASTM D92-18 Pensky-Martens open cup method (equivalent to ISO 2592). The flash point, i.e. the temperature at which vapors can ignite but not stay alight, is 159 °C.

As a hydrocarbon fluid with a fire point of 174 °C, the US NFPA classifies SmartCoolant flammability as 1 on a scale of 0 to 4. This puts the SmartCoolant in the same flammability class as materials like wood and plastic, and less flammable than paper, cardboard, and packing foam (NFPA rating = 2 or higher).

For the combustion of the fluid to occur, three conditions must be met: (1) the entire body of fluid must reach 174°C, (2) there must be an ignition source (e.g., a spark or open flame), and (3) sufficient oxygen must be present. It is important to note that the simultaneous occurrence of these three conditions is very unlikely.

In the rare event of a fire, industry standard passive and active fire protection systems are sufficient.
