Abstract The characteristics of fires in continuous oil spills along various slopes were investigated experimentally to improve theoretical models for the prevention and control of oil spill fires. The spreading and burning rates of continuous oil spill fires along various slopes were observed for point source oil spills. The spill fire spreading was divided into three stages for various slopes based on whether the fire became stable or was shrinking. For the n-heptane spill fire on the glass surface, the relationship between gravity, friction and surface tension forces during the spreading characterizes the three stages as the "surface tension dominant" stage for slopes of 0°-3°, the "friction dominant"stage for slopes of 4°-5° and the "gravity dominant" stage for slopes greater than 5°.
