Sprayer inspection parameters as a basis for risk assessment for human health and the environment

Abstract

In this context the question arises with which methodology such a risk assessment could be done following practical and professional consideration. Some general aspects concerning this topic were already presented by Ganzelmeier (2012). The risk matrix according to Nohl and Thiemecke (1988) is a common method for technical risk assessment also known as Zurich-methodology. It is applied for the assessment of safety risks of aerial railways or even for the assessment of risks arising from the operation of nuclear power plants. A technical risk is the product of probability of occurrence of a certain failure and the extent of the subsequent damage. These two elements of a technical risk can be presented in a matrix distinguished in different qualitative classes (Fig. 1). Aim of the matrix is to define how high a risk might be.
