Proportionality – the role of safety management in climate action
The recently popularised term “Anthropocene” alludes to the impact of human life and endeavour upon the geology and ecosystems of our planet. As the dawn of this new geological epoch breaks upon the Earth, worldwide awareness is steadily rising of the harsh realities of climate change.
Functional safety: a proportional approach to legacy safety systems
The requirement for identification, specification and maintenance of Safety Instrumented Systems (SIS) is contained throughout legislation, with the industry-wide good practice standard being IEC 61508, Functional safety of electrical/ electronic/ programmable electronic safety related systems. SIS are specific electrical or electronic systems that prevent or mitigate the effect of a hazard.
Prescriptive safety: have we gone too far?
In NASA's heyday, the safety of the space shuttle was assured by a strict adherence to 'Flight Rules'. These were black and white rules that identified precisely what action should be taken under specific circumstances.
Proportionality – avoiding ‘one size fits all’ solutions
Proportionality is a fundamental attribute of modern risk management.
Risk-based decision making
Decisions evolve around the need to make choices, either to do or not to do something, or to select one option from a range of options. The choices available are often constrained by social, technical, business, safety and environmental requirements and objectives. Successful decision making requires an understanding of these many requirements and objectives, their relative importance, and how to assess options and make the 'best' decision.
