Hazard and Operability (HAZOP)

A Hazard and Operability (HAZOP) study is a structured and systematic examination of a process or operation to identify and evaluate problems that may represent risks to personnel or equipment, or environment. The Scope of HAZOP includes all process and utility P&IDs forming the scope of the project, all interface P&IDs, Operating and control philosophy, vendor data. It is conducted to examine the overall process design, searching for operating deviations and process interactions that can lead to hazardous situations or operability problems. This can be useful to bring about safety improvements at the Design stage itself in particular and also is effective in ensuring that the plant modifications do not ignore safety aspects.
