Our study focuses on applications of persuasive technologies (Fogg, 2002) as a means to manage risks in technologically advanced industrial sites. An analysis of the production processes of a chemical plant allowed us to identify two risk scenarios where human factors are particularly relevant: in chemicals identification and in the use of personal protective equipment. Possible solutions based on persuasive technologies and aimed at minimizing the occurrence of human errors were prototyped. Qualitative evaluation of the proposed solutions, which involved 7 potential users, both operators and safety engineers (the population consisting of 29 people), allowed us to have a first confirmation of their acceptability and persuasion effectiveness.
