Abstract
This work identified the conditions under which a spill of flammable liquid on an ambient-temperature floor could represent a fire threat to grouped cables in an electric utility installation. Five high-fire-point, flammable, hydrocarbon liquids were tested in this program. They were: No. 2 fuel oil, No. 6 residual oil, Mobile DTE 797 turbine lubricating oil, Pennzoil 30-HD motor oil, and Fyrquel 220 hydraulic control fluid. The following floor materials were tested: float-finished (21 MPa) concrete; epoxy-coated (21 MPa) concrete; and steel. The fire hazard presented by a spill depends on the following five factors: spill depth; thermal inertia of the floor under the spill; fire point of the flammable liquid spill; thermal energy available to heat the spill to its fire point; and the availability of an ignition source to ignite the spill after reaching fire point. The relative importance of each factor is identified.Keywords
