System Safety Group

Operation and System Safety Group. It will cover topics such as criticality control, administrative controls to prevent accidents, radiation protection, normal emission, system failure mode, and human error. 

Organizational interfaces may pose other problems. When management does not take responsibility for decision making in the process, functional and system safety groups may be at odds with each other. Management perception is another difficulty. System-safety concepts are more abstract than those in many other disciplines. Therefore, it is important for the safety professional to structure the program so its impact is clear.

Function event trees include primarily the engineered safety features of the plant, but other systems provide necessary support functions. For example, electric power system failure amid reduce the effectiveness of the RCS heat-removal function after a transient or small UJ( A. Therefore, EP should be included among the systems that perform this safety function. Siipfiort systems such as component-cooling water and electric power do not perform safety functions directly. However, they significantly contribute to the unavailability of a system or group of systems that perform safety functions. It is necessary, therefore, to identify support systems for each frontline ssstcm and include them in the system analysis. 

Because of the expense and effort of a comprehensive vahdation this review may be very cost-effective. The reclassification of a single system from group A to group B may result in saving 50,000 or more without compromising product or process safety, quahty, or regulatory acceptance.

Serious adverse events that are seen in clinical trials and in the general use of marketed products need to be reported directly to a safety group or safety coordinator. Safety groups tend to operate and maintain their own databases for these SAE reports, or cases, because of the detailed information related to each case that they must collect (Prokscha, 2007). Each SAE case is initially entered in this system and then updated as follow-up information becomes available. 

System safety interfaces with other groups, such as maintenance and test, occupational safety, quality assurance, and so on. 

An Internet Resource. Jacobs Engineering Group Inc. is one of the world s largest and most diverse providers of professional technical services. Jacobs Sverdmp is its technology company, and its staff is extensively involved in system safety. Many of its publications are available on the Internet and are downloadable, free, in accord with Terms of Use. Freely providing this resource and literature for interested persons is an impressive public service. I was encouraged by Pat Clemens of Jacobs Sverdmp to provide access information.

Safety community That group of individuals who provide staff support to the line organization in support of the safety effort. It includes occupational and industrial safety, system safety, industrial hygiene, health, occupational medicine, environmental safety, fire protection, reliability, maintainability, and quality assurance personnel. 

At the working level, system safety tasks are normally performed by a system safety working group (SSWG). One of the reasons that a system safety working group or a team approach is generally used in system safety efforts is that multiple talents and disciplines are required in order to provide for the first-time safe, efficient operation of the entire system (Fig. 2-6). 

A system safety working group should have representatives from at least four groups or communities. Name them and discuss the skills or knowledge that each representative brings to the system safety effort.
