This applies when entering shafts and cavities or when a gas smell is detected. From a measured value of 2.2 vol.-% = 50 % LEL, the room cannot be entered and working on a pipeline is prohibited.

    Acetone - Chemical Safety Facts

    14/10/2022· Acetone is frequently incorporated in solvent systems or “blends,” used to make lacquers for automotive and furniture finishes. It may also be used to reduce the viscosity, or thickness, of lacquer solutions. Safety Information Acetone safety Acetone has been extensively studied and is generally recognized to have low acute and chronic toxicity.

    Flammability limit - Wikipedia

    Lower flammability limits for many organic materials are in the range of 10–50 g/m³, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds of this concentration are hard to see through for more than a short distance, and normally only exist inside process equipment.

      Summary: Acetone is a manufactured chemical that is also found naturally in the environment. It is a colorless liquid with a distinct smell and taste. It evaporates easily, is flammable, and dissolves in water. It is also called dimethyl ketone, 2-propanone, and beta-ketopropane. Acetone is used to make plastic, fibers, drugs, and other chemicals.
