OSHA PEL superati/revocati

PEL, Permissible exposure levels - Valori limite permessi
Valori di esposizione limite indicati dall'OSHA (l’Organizzazione governativa statunitense per la sicurezza sul lavoro).
In questo caso quindi si tratta (vedi sotto) di valori limite permessi da OSHA ormai superati/revocati/abbandonati dato che ne sono stati dati di nuovi

Permissible Exposure Limit (PEL)
Time-Weighted Average (TWA)

Definition
A Permissible Exposure Limit (PEL) is the maximum amount or concentration of a chemical that a worker may be exposed to under OSHA regulations.

A Time-Weighted Average (TWA) is explained below.

A VPEL or Vacated PEL is an older PEL set by OSHA but later "vacated" (retracted) under court order. However, some states may continue to enforce these lower levels. See below.

Vacated PEL's

Analyzing the specific health risks and performing the cost/benefit analyses needed to set a PEL is a time-consuming and labor-intensive endeavor. As a result, only ~470 substances have OSHA PEL's.
In 1989, OSHA decided that it was impractical to set PEL's for tens of thousands individual chemicals and enacted a generic rulemaking scheme that broke chemicals up into various categories. This methodology was challenged in court and in AFL-CIO v. OSHA, 965 F.2d 962 the 11th U.S. District Court of Appeals vacated (struck down) the 1989 PEL revisions stating "(1) OSHA failed to establish that existing exposure limits in the workplace presented significant risk of material health impairment or that new standards eliminated or substantially lessened the risk; (2) OSHA did not meet its burden of establishing that its 428 new permissible exposure limits (PELs) were either economically or technologically feasible."
