ALARP is an English acronym meaning As Low As Reasonably Practicable (as low as reasonably practicable ).
It is a principle of risk reduction, which finds application, for example, in risk management. The ALARP principle is that risks should be reduced to a level that guarantees the highest level of security, it is reasonably practicable ( limiting the maximum loss expectancy ). This means for example, that in product development measures for identified product risks need to be implemented only if they are also reasonably practicable ( financially and / or technically feasible at a reasonable cost ).
The ALARP principle in risk management (see also Probabilistic Safety Analysis ) was used. Within a risk management process is using a risk graph ( RISK MATRIX ) determines which risks within the acceptable range, which that are in the ALARP region and in the unacceptable range. The classification of the risk graph is project- specific and usually requires that the two parameters are defined probability and extent of damage.
In a continuous risk management process existing risks are continuously monitored and evaluated, as well as new risks are identified. Based on an evaluation of the parameter likelihood and extent of damage for every single risk, it is classified in the same risk graph. Hazards inherent in the unacceptable range should be brought by risikoverringernde measures in the ALARP region. If this is not possible, then using a cost-benefit analysis ( cost-benefit analysis) to determine whether the expected benefits outweigh the risks.
