A role for human reliability analysis (HRA) in preventing drinking waterincidents and securing safe drinking water

摘要

The prevalence of water quality incidents and disease outbreaks suggests animperative to analyse and understand the roles of operators and organisations inthe water supply system. One means considered in this paper is through humanreliability analysis (HRA). We classify the human errors contributing to 62drinking water accidents occurring in affluent countries from 1974 to 2001;define the lifecycle of these incidents; and adapt Reason's ‘Swiss cheese’ modelfor drinking water safety. We discuss the role of HRA in human error reductionand drinking water safety and propose a future research agenda for human errorreduction in the water sec
