System safety working groups

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.

An effective system safety working group includes representatives from levels three, four, five, and six (U.S. Air Force 1987).

Which problems can be significantly ameliorated by the use of well-organized and well-managed system safety working groups Explain. 

The PHL is normally prepared by the system safety working group and reviewed by management review boards. 

An accident analysis report may be prepared by the system safety working group and/or an independent accident investigation board. The recommended method for serious accidents is for the SSWG to prepare an accident analysis report based on its own investigation and upon the findings of the traditional accident report prepared by the accident investigation board. 

Members of the system safety planning group normally become members of a system safety working group or safety review board. 

Step 8 Select system safety working group criteria... 

Normally, a separate system safety working group (SSWG) is designated for each project. In some situations, however, one SSWG may successfully participate in multiple projects.

Step 17 Establish system safety working groups... 

The system safety working group expands the PHL into a PHA as described in Chapter 8 (or as outlined in the system safety program plan). 

Outline the recommended composition of a system safety working group (SSWG), and discuss the knowledge and skills that each member is expected to contribute. 

Analytical trees make excellent project description documents because they are relatively easy to construct and easy to understand. Many end users and some safety professionals, engineers, and managers are not skilled in reading blueprints, electrical schematics, or other technical documents. The analytical too is an excellent means for communicating project information within a system safety working group. 

After the initial risk categorization, the next step in the risk assessment process is the systematic identification of hazards associated with the project. Hazard discovery is the responsibility of all members of the system safety working group and others associated with the project. Other risk management responsibilities are dependent on the level of the risk, with decisions involving more significant risks reserved for senior commanders or managers. 

Use of the TREC allows the system safety working group to provide the project manager with the following types of information ... 

This problem alone may justify the formation of a system safety working group that includes the user community. 

The design engineer, aided by the system safety working group, systematically reviews all aspects of systems to determine why and how persons may use the system, subsystem, or component improperly and attempts to identify, analyze, and control hazards associated with misuse. 

Sometimes referred to as energy flow analysis, HazOps is used primarily in the petrochemical industry. It uses a multidisciplinary team similar to a system safety working group for the systematic review of the flow of materials through a process. It concentrates on key locations in the process known as study nodes and uses a series of guide words and parameters to examine possible deviations and the causes and consequences of deviations (Goidwaite 1985).
