Flash point and ignition are among the main indicators of the fire hazard of substances, as they characterize the fire and explosion hazard of vapor-air mixtures above the surface of liquids. The paper experimentally investigated the change in the flash point and ignition of flammable liquids (diesel fuel and industrial oil) with the addition of inert additives − perlite, activated carbon, silica gel, oilcorb and vermiculite. Oil-sorb and vermiculite showed the greatest efficiency. When adding the oil filler to diesel fuel, the flash point in the open crucible increased by 7.8 ° C and approached the ignition temperature.
