Quinone

IDLH Documentation
CAS number: 106­51­4

NIOSH REL: 0.4 mg/m3 (0.1 ppm) TWA

Current OSHA PEL: 0.4 mg/m3 (0.1 ppm) TWA

1989 OSHA PEL: Same as current PEL

1993­1994 ACGIH TLV: 0.44 mg/m3 (0.1 ppm) TWA

Description of substance: Pale­yellow solid with an acrid, chlorine­like odor.

LEL: . . . Unknown

Original (SCP) IDLH: 300 mg/m3

Basis for original (SCP) IDLH: The chosen IDLH is based on the mouse LCLO of 320 mg/m3 [Zabolevanii 1962 cited by NIOSH 1976]. No other data on acute inhalation toxicity are available on which to base the IDLH.

Short­term exposure guidelines: None developed

Human data: None relevant for use in determining the revised IDLH.

Revised IDLH: 100 mg/m3

Basis for revised IDLH: No inhalation toxicity data are available on which to base an IDLH for quinone. Therefore, the revised IDLH for quinone is 100 mg/m3 based on acute oral toxicity data in animals [Woodward et al. 1949]. This may be a conservative value due to the lack of relevant acute toxicity data for workers.
