May 1994 Immediately Dangerous to Life or Health Concentrations (IDLH)

CAS number: 78–92–2

NIOSH REL: 100 ppm (305 mg/m3) TWA, 150 ppm (455 mg/m3) STEL

Current OSHA PEL: 150 ppm (450 mg/m3) TWA

1989 OSHA PEL: 100 ppm (305 mg/m3) TWA

1993-1994 ACGIH TLV: 100 ppm (303 mg/m3) TWA

Description of Substance: Colorless liquid with a strong, pleasant odor.

LEL(@212 F): 1.7% (10% LEL(@212 F), 1,700 ppm)

Original (SCP) IDLH: 10,000 ppm

Basis for original (SCP) IDLH: The chosen IDLH is based on the statements by Patty [1963] that 10,670 ppm for 225 minutes and 16,000 ppm for 160 minutes were fatal for mice [Weese 1928]. According to Patty [1963], at 20,000 ppm it took 12 to 20 minutes to produce prostration in mice and 40 minutes to produce narcosis; no deaths occurred [Starrek 1938]. The chosen IDLH is probably conservative.

Short-term exposure guidelines: None developed
