System safety risk ranking

One of the attributes of a positive safety culture is when safety items receive prompt attention. High-risk practices and acts that are reported should receive attention, and remedial measures should be forthcoming. Reports of near-miss incidents should be recorded, tracked, and feedback given to everyone, not only the reporter. A system of risk ranking is useful in allocating resources and priorities to safety action items. If not ranked, all safety items will be considered as priority, and with all items being the priority, none will be handled in a timely manner. 

Administration Building. To reduce the risk from the potential blast that could occur from either gas compression/reaction or feed purification/vaporization, safety film was installed over the windows, a catch system was provided to capture flying window fragments, and overhead fixtures were secured. This reduced the risk ranking for the administration building to IV.

The final step in the process is to create safety risk metrics for each candidate architecture. Because the system engineers on the project created hundreds of feasible architectures, the evaluation process was automated. The actual details of the mathematical procedures used are of limited general interest and are available elsewhere [59]. Weighted averages were used to combine mitigation factors and severity factors to come up with a final Overall Residual Safety-Risk Metric. This metric was then used in the evaluation and ranking of the potential manned space exploration architectures. 

Professional safety practice requires that hazards be analyzed, that the risks deriving from those hazards be assessed, and that a risk ranking system be utilized. Also, it must be understood that hazard analysis is... 

Establishing correct safety procedures is when a manager analyzes certain tasks and writes safe work procedures for performing the work. Based on risk assessments, the tasks can be risk-ranked and the critical tasks identified. This will help prioritize the writing of procedures. Specific inspection procedures, equipment maintenance procedures, internal audit procedures, and other procedures are vital components of the system. 

A few critical jobs conld be responsible for the majority of accidents and injuries occurring within an organization. The safety managanent system should incorporate a risk-ranking procedure of all tasks carried out in the various departments in order to isolate the critical few that have major potential to cause loss.

Failure Modes and Effects Analysis (FMEA) examines systems, element by element (Systems Safety Society 1997,3-111). The analysis procedure requires the identification of the individual components that make up the system under examination. With the components identified, the modes in which the component failures as well as the effects that that failure has upon the system are determined. A further step to the FMEA procedure is the examination of the risk associated with the failure. The risk, also referred to as criticality, provides the investigators with a method of ranking the hazards in the system and providing a method for prioritization of hazards.
