HAZOP (Hazard and Operability Study)
HAZOP study is to carefully review a process or operation in a systematic manner to determine whether deviations from the design or operational intent can lead to undesirable consequences
Definitions
Parameter
Something the process is based on
Deviation
How a change to the parameter affects the system
Cause
Happened for the deviation to occur
Consequence
What will happen because of the devation
Recommendations
What should be carried out to remove the risk of an incident occuring
