Flash and ignition temperatures are key indicators of the fire hazard of liquids, since it is from these values that combustible and flammable liquids become potentially dangerous for the technosphere and can cause an emergency. To reduce the likelihood of a fire situation developing in places with the circulation of flammable and combustible liquids (FL and FL), it is necessary to increase the flash point and ignition of FL and FL. The paper shows the effect of adsorbents (perlite, activated carbon, silica gel, oil sorb and vermiculite) on the change in the flash point and ignition of combustible liquids (diesel fuel and industrial oil I-20A). Petrosorb and vermiculite showed the greatest efficiency. Neftesorb and vermiculite showed their effectiveness both in closed and open crucible (in some cases, the increase in flash and ignition temperatures reached 10 ° C). Silica gel has shown its effectiveness only in the open crucible of diesel fuel
