2. (    ) in the year of proposal column indicates that revision was done in the year without change of the OEL value.
3. *: Occupational Exposure Limit-Ceiling; exposure concentration must be kept below this level.
**: Fibers longer than 5 μm and with an aspect ratio equal to or greater than 3:1 as determined by the membrane filter method at 400 ×
magnification phase contrast illumination.
ψ: Substance whose OEL is set based on non-caninogenic health effects; see III.
a: Exposure concentration should be kept below a detectable limit though OEL is set at 2.5 ppm provisionally.
b: OEL for gasoline is 300 mg/m3, and an average molecular weight is assumed to be 72.5 for conversion to ppm unit.
c: Not applicable to women of child bearing potential.
†: Provisional.
