Computer software data bases PRINTS

A worksheet (data base spreadsheet) form is used to collect and collate the process hazard analysis review data. A computer software generated spreadsheet is typically used. For a complete description of commercially available HAZOP or What-If software, the user should refer to the manufacturer s HAZOP or What- If software User Instructions. Although pre-printed forms may be used, they are highly inefficient and should be maintained only as a backup in case of computer hardware or software failures. 

The American Chemical Society (ACS) publishes 19 primary journals. Chemical Abstracts (CA), computer-readable and on-line data bases, and many other publications in chemistry. Chemical Abstracts Service (CAS), a division of the ACS located in Columbus, Ohio, does most of the computer processing and software development for these publications and data bases. ACS publications and data bases contain chemical structures, tables, equations, line drawings, and other images. CAS continues to automate the processing of graphics for both printed publication and on-line data base publication.
