FOOTNOTES
1.
In AFL-CIO v. OSHA 965 F. 2d 962 (11th Cir. 1992), the court overturned OSHA’s 1989 Air Contaminants Rule,
including the specific PELs for wood dust that OSHA had established at that time. The 1989 PELs were: TWA - 5
mg/m
3
; STEL (15 min.) - 10.0 mg/m
3
(all soft and hard woods except Western red cedar); Western red cedar TWA-2.5
mg/m
3
.
Wood dust is now officially regulated as an organic dust under the Particulates Not Otherwise Regulated (PNOR) or
Inert or Nuisance Dust categories at PELs noted under PART II of this MSDS. However, a number of states have
incorporated provisions of the 1989 standard in their state plans. Additionally, OSHA has announced that it may cite
companies under the OSH Act General Duty Clause under appropriate circumstances for non-compliance with the
1989 PELs.
