Some of these which are commonly used include the following: CAS N:This is the Chemical Abstract Service Number which uniquely identifies each constituent. It is used for computer-related searching.

Permissible Exposure Limits are based in the 1989 PELs and the June. 1993 Air Contaminants Rule (Federal Reoister: 58: 35338- TOXICOLOGICAL INFORMATION: 35351 and 58: 40191).
