HAZOP

HAZOP is a rigorous and widely accepted technique for hazard identification. A system or process is studied by a team who systematically look for the cause and effect of deviations from the norm. The team will, in general, be considering the following questions:
• What is the design intention of the plant?
• What deviations from the design could occur?
• What might cause such deviations from the design intention?
• What would be the consequences of such deviations from the design intention (such as fire, toxic release, etc.)?
See appendix 6 for further information on HAZOP studies.
