Storing Flammable Liquids
Never keep flammable liquids or combustible material near your furnace or water heater, vent pipe or any ignition source. Vapors from paint thinner, gasoline, cleaning solvents and contact cement, to name a few, can catch fire or explode if exposed to a flame or spark.
When you use flammable liquids, do so in an open, well-ventilated area, far away from any possible source of ignition.
