HAZOP analysis is a systematic method on the basis of the experts' experience and knowledge and is used for hazard identification and risk assessment by using brainstorming method. So, HAZOP analysis has been applied to major chemical industries efficiently. But it does not apply to small and midium chemical industries because of the insufficiency of the experts. Hence, in this study a new hazard identification method is proposed by modifying complexity and expertise of the HAZOP analysis and will be contributed to improve risk management for small and midium chemical industries.
