¹
In AFL-CIO v. OSHA 965 F. 2d 962 (11
th
Cir. 1992), the court overturned OSHA’s 1989 Air Contaminants Rule, including
the specific PELs for wood dust that OSHA has established at that time. The 1989 PELs were: TWA 5 mg/m³; STEL (15
MIN) – 10mg/m³ (all softwoods and hardwoods, except western cedar); western red cedar: TWA – 2.5 mg/m³.
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 the Hazardous Ingredients section 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.
