Furfuryl alcohol
May 1994
Immediately Dangerous to Life or Health Concentrations (IDLH)
CAS number: 98–00–0
NIOSH REL: 10 ppm (40 mg/m3) TWA, 15 ppm (60 mg/m3) STEL [skin]
Current OSHA PEL: 50 ppm (200 mg/m3) TWA
1989 OSHA PEL: 10 ppm (40 mg/m3) TWA, 15 ppm (60 mg/m3) STEL [skin]
1993-1994 ACGIH TLV: 10 ppm (40 mg/m3) TWA, 15 ppm (60 mg/m3) STEL [skin]
Description of Substance: Colorless to amber liquid with a faint, burning odor.
LEL: . . 1.8% (10% LEL, 1,800 ppm)
Original (SCP) IDLH: 250 ppm
Basis for original (SCP) IDLH: The chosen IDLH is based on the rat 4-hour LC50 of 233 ppm of a furfuryl alcohol, hydrazine, and aniline mixture [Jacobson et al. 1958]. Also, Deichmann and Gerarde [1969] stated that 8% mortality resulted from a 6-hour exposure of rats to 47 ppm furfuryl alcohol and 100% mortality resulted at 243 ppm.
Short-term exposure guidelines: None developed

Other animal data: Exposure of rats to 100 ppm for 6 hours per day, 5 days per week for 16 weeks resulted in decreased weight gain and biochemical changes in the brain (i.e., increased cerebral glial acid-proteinase and phosphohydrase activity) [Savolainen and Pfaffli 1983].
Human data: No discomfort was reported from concentrations up to 10.8 ppm for 15 minutes, but severe lacrimation occurred at 15.8 ppm [Apol 1973]. It has also been reported that there is no hazard from exposures up to 16 ppm [Burton and Rivera 1972].
Revised IDLH: 75 ppmBasis for revised IDLH: The revised IDLH is 75 ppm based on acute inhalation toxicity data in animals [Terrill et al. 1989]. |
