HAZARD ANALYSIS A systematic process for identifying hazards and recommending corrective action. TWO APPROACH : 1. Preliminary Hazards Analysis (PHA) 2. Detailed Hazards Analysis • Comparative Methods • Fundamental Method Ricki M. Mulia
Hazard and operability study (HAZOP) HAZOP enables us to discover how deviation can occur and to consider which deviations from normal operation, or which operational malfunctions, could lead to hazardous event Guide Word Not, No Deviation No Flow Possible Cause No material available at intermediate storage Consequences Action Required Loss of feed to Install low level reaction section alarm in the which may result intermediate storage explosion Ricki M.

Batch Or Continuous Processing Safe Process Design technique The Flow Sheet • Reaction section • Separation section • Materials handling • Storage section Reaction Condition Flow Sheet review Ricki M. Mulia
SAFETY SYSTEM 1. Systems preventing deviation from permissible operating conditions: - pressure-relief system - temperature/pressure/flow sensors -Systems preventing overflow -Safety shut-down systems, emergency shut-off system 2. Systems preventing failure of safety-related components 3. Utilities 4. Alarm system 5. Technical protective measures 6. Mitigating measures 7. Prevention of human and organizational errors Ricki M. Mulia
