Acceptable Risks - When the level of risk is determined to be acceptable, we can conclude the design in question is acceptably safe.
- Generally acceptable levels of safety are codified in the specific design codes for the product or system in question, and the designing engineer only has to adhere to accepted practice.
- But when the proposed design deviates from accepted practice in some parameter, it may be the case that the proposed design introduces yet unidentified risk.
- Risk is managed in different ways in different engineering tasks.
- Risk is managed in engineering design by developing design codes, rules for design proven to produce designs consistent with accepted engineering practice.
- These design rules involve some basic engineering principles, such as redundancy and the design for failure modes that give visual warning.
- Risk is also managed in operation of engineering systems by careful design and continuous review of engineering systems and processes.
