Resources system safety

A related limitation of the model program approach is that these "transplants" rarely take full advantage of opportunities to link PSM into other company systems, for example, using existing human resources systems to manage process safety-related training. 

Lucas (1992) proposes that different safety cultures will have an impact on which accidents are investigated and whether or not near miss reporting is perceived as a valuable use of resources an occupational safety culture would probably investigate only serious personal injuries the risk management culture might be interested in certain types of near misses with very direct and serious potential safety consequences finally a systemic safety culture will encourage its employees to report anything related to possible deviations, either with immediate or delayed consequences for safety control. 

The process industry comprises mainly continuous but batch processes also. The industries involved are chemical, petrochemical, pharmaceuticals, refineries, etc. These are usually very large and complex facilities. The main goal of any process plant is to get the maximum benefit (which means the demanded amount with the specified quality using the less resources) assuring safety and stability of the plant. In order to achieve this goal, control strategies have been applied and evolved over the years as new capabilities were available. From the initial manual control to the current digital distributed control system (DCS). 

Needs analysis The starting point of any system design project is a perceived need. This need must first be established with enough confidence to justify the commitment of resources to satisfy it and understood well enough to allow appropriate solutions to be generated. Criteria must be established to provide a means to evaluate both the evolving and final system. If there are hazards associated with the operation of the system, safety should be included in the needs analysis. 

These recommendations and those resulting from other thoroughly investigated accidents also provide an excellent resource to assist in generating the system safety requirements and constraints for similar types of systems and in designing improved safety control structures. 

In some industries, system safety is viewed as having its primary role in development and most of the activities occur before operations begin. Those concerned with safety may lose influence and resources after that time. As an example, one of the chapters in the Challenger accident report, titled The Silent Safety Program, lamented ... 

The desire to predict the future often leads to collecting a large amount of information based on the hope that something useful will be obtained and noticed. The NASA Space Shuttle program was collecting six hundred metrics a month before the loss of Columbia. Companies often collect data on occupational safety, such as days without a lost time accident, and they assume that these data reflect on system safety [17], which of course it does not. Not only is this misuse of data potentially misleading, but collecting information that may not be indicative of real risk diverts limited resources and attention from more effective risk-reduction efforts. 

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. 

Be responsible and accountable for maintaining the safety element files. Must be knowledgeable and proficient on all aspects of the safety system. Coordinate the design and participate as a resource in safety committee meetings.

Appraisal of potential risk due to the design, the processes, the equipment, the safety barriers, the procedures, the resources. The safety barriers, including technical and organizational systems, have to be taken into accoimt here. It should be stressed that if safety barriers are adequate, they enable a dramatic mitigation of inherent hazards. In actual operation the condition of the safety harriers may deeply change, affecting in this way the overall safety level. 

Management has the overall responsibility for ensuring that system safety programs are established, that they are adequately staffed at all levels, that the training is conducted for all personnel associated with the system safety effort, that safety concerns are identified and communicated, and that adequate resources are allocated. 

Level Three. Contractor s management system safety program. At this level, contractor management provides program oversight, policy, direction, and resource allocation. 

A successful system safety program depends on support and resources from top management, project management, engineering, safety, operations, maintenance, and perhaps other areas like legal, procurement, and marketing. 

System safety program plan A description of the planned methods to be used by the contractor to implement the tailored requirements of this standard, including organizational responsibilities, resources, methods of accomplishment, milestones, depth of effort, and integration with other program engineering and management activities and related systems (MIL-STD-882). 

Because the system safety professional focuses more attention where there are no or insufficient knowledge bases, some in industry perceive that the scope of the system safety discipline is just in those areas, where little or no knowledge bases exist. However, the scope of the system safety discipline is much broader and the system safety professional must have a complete understanding of how to use and apply the existing safety resources, in addition to when to use other system safety analyses to evaluate the entire system throughout its entire life cycle. Some colleagues refer to system safety as the umbrella safety, since you must draw upon all safety resources for the tech-... 

On the one hand, privatization and restructuring have brought about safety improvements and efficiencies in operations. For example, there appears to be a significantly heightened interest in the reliability of those systems and components that can affect power output or threaten regulatory action. The new commercial ownership of some U.K. nuclear power stations has also reduced the former degree of bureaucracy. As a result, it is possible that resources for safety and reliability issues can now be allocated more quickly. 

Without these assurances in place, as a minimum commitment from organizational management, the system safety effort will not succeed. It can be said that the very reason system safety is utilized is to facilitate the decisionmaking process regarding risk or potential risk of failure. Therefore, management must not only provide the necessary resources and companywide commitment needed to accomplish the system safety objectives but also stand ready to accept the results of the system safety process and ensure that appropriate, responsible decisions are made on the basis of all available information. 

Figure 35-3 illustrates the model for SMS used by the International Labour Office (ILO). ILO publishes a guideline " and other resources on safety and health management systems. Its model involves five elements, all working within a focus on continual improvement. 

Previous discussions here on safety requirements have indicated that the scope of system safety analyses must address the system, service and operational environment. This vast scope presents a challenge for the systems engineer who needs to consider the safety-related aspects of the entire system and then to focus the often limited resources available on the most critical system functions. 

In the planning phase the customer requirements have to be assessed and the respective process and resources planning is performed and detailed in a System Safety Plan. 

The principles of system safety are founded on pre-planning and organisation of action designed to conserve all resources associated with the system under review.
