Hazardous Materials

Vapors from flammable and combustible liquids can ignite, causing a fire. Many common household products require additional attention when it comes to use, clean up, and storage.

Safety Tips

Flammable liquids include gasoline, lacquers, and nail polish. Combustible liquids include paint thinner, kerosene, and oil-based paints and stains.

Clean Up

  • Flammable and combustible liquids should not be used near an open flame. Do not smoke when working with these liquids.
  • If you spill flammable and combustible liquids on your clothing, remove your clothing and place it outside to dry. The clothing can be laundered once it is dry.
  • Only use gasoline as motor fuel.
  • Do not:
    • Use as a cleaner.
    • Use to break down grease.
    • Bring gasoline indoors, even in small amounts.

Clean Up

  • Never leave cleaning rags in a pile.
  • Hang the rags outside or spread them on the ground. Weigh them down so they do not blow away. Keep them away from buildings.
  • Place dried rags in a metal container and fill the container with a water and detergent solution. Ensure the cover is on tightly and shake.
  • Keep containers of soiled rags in a cool place and keep them out of direct sunlight and other heat sources. Visit opala.org for information on disposing of them.


  • Keep liquids in their original containers tightly capped or sealed. Never store the liquids in glass containers.
  • Only store gasoline in a container that is sold for that purpose.
    • Ensure the container is tightly capped when not in use.
    • Never store gasoline in a basement or in the occupied space of a building.
    • Keep the containers in an outbuilding, a detached garage, or a shed.
