You ll find presentation material here for classroom use or for self-instruction. There are also workshop problems, and there s our Jacobs Sverdrup System Safety Scrapbook of ideas on the principles of system safety practice. You ll also find four bibliographies of texts pertinent to this field, as well as a System Safety and Risk Management Guide for Engineering Educators. All of these materials undergo revisions from time to time, so revisit the site often to see new and important items. 

Professional credentials or experience in systems safety are not required to appreciate the potential value of the systems approach and system safety techniques to general safety and health practice. Tliis book will help the reader move from system safety practice into far broader applications.

The next step is completing a thorough, orderly, systematic approach for identifying, evaluating, and controlling the hazards of the processes involving the highly hazardous chemicals. There must be documentation of the priority order used for the analysis. The analysis must use one or more of specified methods to determine the hazards and evaluate them. Several of these methods came from system safety practice, discussed in Chapter 36. OSHA Publication 3133 (Note 33) summarizes each of the methods. 

There are some organizations that have formal requirements for system safety practice. As noted, OSHA includes system safety methods in its performance standard for process plants. OSHA also offers guidance on the use of this standard. ... 

The Department of Defense has a long-standing standard on system safety. The standard covers methods and procedures. The Department of Defense also extends system safety practices to software development" and other procurement regulations. Software is often an integral and critical pait of aircraft, weapon, and other systems. Software can introduce hazards for those involved with a system. 

The ultimate responsibility for safety rests with me operating company OSHA 1910.119 is clear on this. Each company is expected to develop (and enforce) its own practices in the design, installation, testing, and maintenance of safety systems. Fortunately, some companies make these documents public. Monsanto s Safety System Design Practices was published in its entirety in the proceedings of the International Symposium and Workshop on Safe Chemical Process Automation, Houston, Texas, September 27-29, 1994 (available from... 

Each chapter starts with a description of the topic covered in the chapter. This is followed by a short example highlighting a reported incident involving a batch reaction system. The case study is followed by a listing of key issues and process safety practices unique to the topic. The issues and concerns presented in this book, as well as potential design solutions and sources of additional information are presented in the tables. This format concisely conveys the necessary and relevant information in a familiar and convenient format. The organization of the tables is described below. 

Listed below are some process safety practices which can help reduce accidents due to instrumentation and control systems.

An inherently safer system should have inspection and reliability testing of safety critical systems and practices (CCPS, 1993c). 

Where an effective informal system exists and is followed, the issue is one of style, not substance. A facility or unit may have a strong safety culture and sound safety practices, but its managers lack the habit of form documentation, or simply don t think it is important. Assuming that safety performance meets applicable standards, you will probably assign cases like these a relatively low priority, compared with other noncompliance situations. Cases like these are also often the easiest to fix since the fundamentals are already in place, what s required is simply to formalize the informal system by preparing and implementing documentation procedures.

General Considerations The following should be taken into account whenever designing or operating a chemical process that involves intended chemical reactions (Hendershot 2002). CCPS (1999) also details many key issues and process safety practices to consider that are oriented toward the design and operation of batch reaction systems.
