2 Unsafe Act Unsafe Condition HAZARD EXPOSURE Penyakit Akibat kerja RISK Kecelakaan kerja Higiene Industri Kesehatan Kerja Keselamatan Kerja Ricki M. Mulia

3 HAZARD ANALYSIS Ricki M. Mulia TWO APPROACH : A systematic process for identifying hazards and recommending corrective action. 1. Preliminary Hazards Analysis (PHA) 2. Detailed Hazards Analysis Comparative Methods Fundamental Method

4 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 DeviationPossible Cause Consequences Action Required Not, NoNo FlowNo material available at intermediate storage Loss of feed to reaction section which may result explosion Install low level alarm in the intermediate storage Ricki M. Mulia

5 Safe Process Design technique The Flow Sheet Batch Or Continuous Processing Reaction Condition Reaction section Separation section Materials handling Storage section Flow Sheet review

6 SAFETY SYSTEM Ricki M. Mulia 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

7 The technique of safe process design Reaction Section: The Feed System The Reactor System The Outlet system Separation Section: Crushing Grinding Size separation Distillation Absorption Extraction Filtration Drying Ricki M. Mulia Materials Handling: Piping Solids Handling Storage Section: Sizing Solids storage Liquid storage Gas storage
