Carcinogenic classification:

EPA Inhalation Reference Concentration (RfC): Not established

ATSDR Inhalation Minimal Risk Levels (MRLs): 26 ppm (acute); 13 ppm (intermediate); 13 ppm (chronic)

NIOSH IDLH concentration: 2500 ppm (10% LEL)

Notes on other potential health effects and hazards:

  1. Vapor/air mixtures of acetone may be explosive (NIOSH/IPCS 1994).
  2. EPA's oral reference dose (daily oral exposure likely to be without an appreciable risk of deleterious effects during a lifetime) for acetone is 0.9 mg/kg/day based on kidney effects (EPA 2003; Dietz et al. 1991). Data were considered insufficient to recommend a reference concentration (EPA 2003).
  3. Occupational exposures of acetone may be high enough to produce ketosis in some workers (ATSDR 1994).
  4. Odor and irritation thresholds may be substantially higher in acetone-exposed employees compared to those not exposed, due to sensory adaptation (Wysocki et al. 1997).
