Life-cycle safety activities

Table 4.1 shows where each of the major safety milestones fits into the system life cycle. Safety activities are listed on the left-hand side. The remainder of the table describes the kinds of activities to be performed during each phase of the life cycle. As you can see, many of the activities are repeated throughout the life of the system, such as implementing and maintaining the system safety program plan (SSPP).

Life-cycle safety activities. The procedures should stipulate the safety activities that typically need to be conducted during the various phases of the system s life. These procedures could be formulated around either (or both) the safety case approach (see Chapter 10) or the SSA approach (see Chapter 9).

The AP1000 Life Cycle Safety Report (LCSR) (Reference 9.10) sets out the safety and quality philosophies for the deployment of an APIOOO in the UK. This report demonstrates that the design is safe, and that constmction, operation and decommissioning activities will result in a plant of appropriate quality. It also demonstrates that the constmcted plant will be optimised for operation within safe limits. 

Introduction and commercial application Safety and the environment have become important elements of all parts of the field life cycle, and involve all of the technical and support functions in an oil company. The Piper Alpha disaster in the North Sea in 1988 has resulted in a major change in the approach to management of safety of world-wide oil and gas exploration and production activities. Companies recognise that good safety and environmental management make economic sense and are essential to guaranteeing long term presence in the industry.

The DfE partnership will develop information to improve the understanding of the environmental and human health impacts of new and current materials that can be used to meet the fire safety requirements for circuit boards. Project partners include electronics manufacturers, component and board manufacturers, chemical companies, trade associations, environmental groups, universities and governments. The project will consider environmental and human health impacts that can occur throughout the life cycle of a material, from development and manufacture, through product use and end of life of the material or product. Stakeholders have expressed a particular interest in understanding the combustion products that could be formed during certain end of life scenarios. The list of active partners includes ... 

The concept of Product Stewardship in the polyurethanes industry is discussed, as one of the six elements of the Responsible Care programme used by companies. A Product Stewardship programme is said to demonstrate commitment to Responsible Care and ensures health, safety and environmental protection through active assessment of products throughout their life cycle from... 

The regulatory authorities require the pharmaceutical manufacturer to maintain guidelines and procedures for all activities that could impact the quality, safety, identity, and purity of a pharmaceutical product. This includes procedures for implementing and supporting the validation life cycle and for process operation. 

The result of the consideration that there are similar activities in both the security and safety life cycle, a unified approach is proposed ... 

Activities may differ very much between Safety and Security depending on requirements. As an example, the Decommissioning and Disposal phase can be discussed briefly (Life Cycle Phase 16) ... 

There are two questions most commonly faced by validation organizations "What do we validate " and "How does validation differ from normal project activities such as Factory Acceptance Testing and Site Acceptance Testing " The answers are that we validate GxP critical aspects of the system, i.e., those aspects that can have a direct or indirect impact on product quality, safety and efficacy. Validation is essentiaily a term used to denote the additional rigor applied to the management and documentation of the each phase of the development and operational life cycle of the system. 

The criteria 1 to 8 may be reduced, especially those requiring full application of lEC 60880. Quality assurance shall divide the development and the modification phases of the software safety life cycle into specified activities. These activities shall include all what is necessary to achieve the required software quality, to verify that this quality is achieved, and to provide objective evidence to that effect. ... 

The skills and knowledge required to implement any of the activities of the safety life cycle relating to the safety instrumented systems should be identified and for each skill, the required competency levels should be defined. Resources should be assessed against each skill for competency and also the number of people per skill required. When differences are identified, development plans should be established to enable the required competency levels to be achieved in a timely manner. When shortages of skills arise, suitably qualified and experienced personnel may be recruited or contracted. 

The standards [l]-[3] concern the entire life cycle of a plant ( safety life cycle ), i.e. all activities required for realizing safety functions during a period which begins with the concept phase of a project and ends when aU safety functions are no longer available for use. In addition to quantitative requirements the standards contain numerous qualitative requirements, which are not discussed here. However, it must be borne in mind that fulfilling the qualitative requirements does not automatically lead to the quantitative requirements being fidfilled. 

Kirilenko V.P., Malyshev L.P., Skaridov A.S. (1992) Working out of the Principles of Law Guarantees of Ecological Safety of the Processes of Military Activity in all Stages of the Life Cycle of Weapon Systems and Technical Facilities Fund of National and International Security, Moscow. 

The cornerstone of a sound program for prudent laboratory practices is a process designed to comprehensively review the operations and potential hazards associated with each experiment over its life cycle. This review should take place before any work is conducted. The diverse nature of research and development activities makes it advisable to have such a process in place as part of the scientific method of experimentation. In laboratories where this preliminary survey is routinely practiced, it has proved to be useful in both the maintenance of safe laboratory operations and the minimization of chemical exposure and waste generation. Because of the diversity of types of researchers and laboratory work, such processes— both formal and informal—can help individuals associated with new, modified, or unfamiliar experiments or procedures to plan and work safely, responsibly, and productively. By first evaluating the work area, materials, equipment, and procedures in depth, hidden hazards may be identified and addressed. The pre-experiment review process can also help to ensure that every experiment and laboratory operation complies with all applicable laws, regulations, and other policies. Moreover, by addressing all relevant health, safety, and environmental issues when an experiment is first conceived, further research, scale-up, or development based on it can be made safer and more effective.
