The process of improving safety in modern industrial systems continues
to stimulate considerable debate. One way this issue is being address
ed is through the expansion of training programs and the use of other
behavioural interventions. The success of this depends on the identifi
cation of appropriate interventions. By considering the problem as one
in which we wish to understand the knowledge and beliefs associated w
ith a task, the problems faced by those involved in the assessment of
training needs and other behavioural interventions can be seen as thos
e already familiar to knowledge engineers involved with the constructi
on of intelligent knowledge based systems. It is argued that the exper
ience gained in addressing the problems associated with knowledge acqu
isition, can be equally well applied to the process of safety assessme
nt. Two simple pilot studies are described to illustrate one way in wh
ich knowledge acquisition could be used to identify potential safety t
raining needs.
