However, no waranty is expressed or implied regarding the accuracy of these data or the results to be obtained from the use thereof. AIRGAS, Inc. assumes no responsibility for injury to the vendee or third persons proximately caused by the material if reasonable safety procedures are not adhered to as stipulated in the data sheet.Additionally, AIRGAS, Inc. assumes no responsibility for injury to vendee or third persons proximately caused by abnormal use of the material even it reasonable safety rocedures are followed. Furthermore,vendee assumes the risk in his use of the material. DEFINITIONS OF TERMS A large number of abbreviations and acronyms appear on a MSDS. Some of these which are commonly used include the following: CAS#:This is the Chemical Abstract Service Number which uniquely identifies each constituent. It is used for computer-related searching.

The OSHA explode or ignite in the presence of an ignition source. Permissible Exposure Limits are based in the 1989 PELs and the TOXICOLOGICAL INFORMATION: June, 1993 Air Contaminants Rule (Federal Register: 58: 35338- Possible health hazards as derived from human data, animal 35351 and 58: 40191). Both the current PELs and the vacated studies, or from the results of studies with similar compounds are PELs are indicated. The phrase, 'Vacated 1989 PELF is placed presented.Definitions of some terms used in this section are:LDw- nexl to the PEL which was vacated by Court Order.
