The development section serves as an intermediary between laboratory and industrial scale and operates the pilot plant. A dkect transfer from the laboratory to industrial-scale processes is stiH practiced at some small fine chemicals manufacturers, but is not recommended because of the inherent safety, environmental, and economic risks. Both equipment and plant layout of the pilot plant mirror those of an industrial multipurpose plant, except for the size (typically 100 to 2500 L) of reaction vessels and the degree of process automation.

This guideline describes methods to help the chemical processing industry apply the CCPS chemical process safety concepts to outsourced manufacturing operations, specifically the tolling vendor-client relationship. In addition to the focus on process safety, information and examples provided in this text foster good practices relative to community and worker health, and environmental responsibility.

The American Chemistry Council, formerly the Chemical Manufacturers Association (CMA), and the American Institute of Chemical Engineers Center for Chemical Process Safety (AIChE/CCPS) have jointly published Evaluating Process Safety in the Chemical Industry User s Guide to Quantitative Risk Analysis. This is a revised and updated edition of Evaluating Process Safety in the Chemical Industry A Manager s Guide to Quantitative Risk Analysis, published in 1989 by CMA. 

The MSDS from the chemical manufacturer identifies hazards for entry in the spreadsheet in columns 8 and 10. This is performed for all chemicals that are associated with the process, if the analysis is hmited to a process, or for a plant. The spreadsheet may be filled out variously according to convenience and effectiveness. It is practically impossible to get all needed information from documentation alone. A plant walk-through is advised for viewing operating conditions as they exist, for interviewing operators about the risk concerns that they have, and about the operability of safety and mitigation systems. These results are entered into the spreadsheet.

The Chemical Manufacturers Association s Code of Management Practice for Process Safety is oriented toward the chemical industry, and describes the elements of a process safety management program as part of CMA s Responsible Care program. 

Process safety management has been applied primarily in the chemical process industries. However, the concepts of PSM, and the approaches used for implementing PSM, can be applied equally well to any manufacturing process that uses chemical products. Manufacturing industries as diverse as semiconductor manufacturing 2md food processing can, and do, apply PSM to improve safety and operations. 

Despite the lack of interest in human factors issues in the CPI in the past, the situation is now changing. In 1985, Trevor Kletz published his landmark book on human error in the CPI An Engineer s View of Human Error (revised in 1991). Several other books by the same author e.g., Kletz (1994b) have also addressed the issue of human factors in case studies. Two other publications have also been concerned specifically with human factors in the process industry Lorenzo (1990) was commissioned by the Chemical Manufacturers Association in the USA, and Mill (1992), published by the U.K. Institution of Chemical Engineers. In 1992, CCPS and other organizations sponsored a conference on Human Factors and Human Reliability in Process Safety (CCPS, 1992c). This was further evidence of the growing interest in the topic within the CPI.

Process Safety Management (PSM) is the application of management systems to identify, understand, and control chemical and manufacturing process hazards and to prevent process-related injuries and incidents. 

Safety. The MR is much safer than the MASR. (1) The reaction zone contains a much smaller amount of the reaction mixture (hazardous material), which always enhances process safety. (2) In case of pump failure, the reaction automatically stops since the liquid falls down from the reaction zone. (3) There is no need to filter the monolithic catalyst after the reaction has been completed. Filtration of the fine catalysts particles used in slurry reactors is a troublesome and time-consuming operation. Moreover, metallic catalysts used in fine chemicals manufacture are pyrophoric, which makes this operation risky. In a slurry reactor there is a risk of thermal runaways. (4) If the cooling capacity is insufficient (e.g. by a mechanical failure) a temperature increase can lead to an increase in reaction, and thus heat generation rate.
