Strategies for hazard management process II

Regarding hazard and risk management, one of the early decisions to be taken is to select the strategy for mitigating risk related to hazard. The most effective way is to eliminate the hazard from the system completely. This is, however, not always possible due cost, performance, usability, or other reasons. In such case, other measures need to be considered to mitigate the risks. In this paper, we present two of these strategies, namely active and passive protective measures, in a design pattern format. In many cases, a passive protective measure should be considered initially and preferred over an active protective measure whenever meaningful. Still, both strategies have their applications, and it is finally the designers' decision whether either is good fit for the considered risk. Categories and Subject Descriptors.
