Life safety principles

System safety may grow as a separate discipline or the system safety effort may be absorbed into the mainstream of industrial safety, loss prevention, risk management, loss control, or some other program. A new name or buzzword may appear. Nevertheless, the need for first-time safe systems and for the application of system safety principles, tools, and techniques to systematically identify, analyze, and control hazards as early in the life cycle as possible (with continuing efforts throughout the life cycle) will continue to grow indefinitely. 

People have started to realize that the biggest value they have is their own life and its quality, and that is where understanding the culture of safety principle as apart of the culture of life, and especially its use in professional and private life, originates. 

Note This standard interprets the general requirements of lEC 61508 parts 1 and 2 for the nuclear industry. It follows similar safety life cycle principles but has deviations from lEC 61508 that are specific to the nuclear power industry. 

Preamble. Engineering is an important and learned profession. The members of the profession recognize that their work has a direct and vital impact on the quality of life for all people. Accordingly, the services provided by engineers require honesty, safety and welfare. In the practice of their profession, engineers must perform under a standard of professional behavior which requires adherence to the highest principles of ethical conduct on behalf of the public, clients, employers and the profession. 

The manner of using toxic chemicals (e.g., use of pesticides nearly 50 years ago) with overenthusiasm made us throw the elementary caution of safety to the wind. We followed the same trend of management with scores of newer and exciting chemicals. The goal for us now in the twenty-first century is to move forward and address the problem with pragmatism and precautionary principles to achieve maximum safety and improve quality of life.
