Some fire and explosion incidents in the workplace including large chemical plants have occurred since 2011. It is pointed out that insufficient risk assessment has been implemented in using hazardous materials and chemical reaction of treating chemical substances due to understand insufficiently them. In this paper, the procedure and tool of risk assessment in Japan and overseas considering unintended reactions were surveyed, and issues in implementing risk assessment were coordinated. Moreover, the considerations of support measures for implementing risk assessment considering unintended reactions were investigated. Therefore, one of solutions is to show some typical scenarios related to some critical events (runaway reactions, fire and explosion due to chemical incompatibility, explosion of self-reactive materials etc.). These typical scenarios can be consulted in considering entire scenarios related to unintended reactions, and implementing risk assessment considering unintended reactions.
