Study Notes
Inherent Safety in the Process Industry
- Inherent Safety emphasizes designing processes that eliminate hazards rather than controlling them through protective measures.
- Focuses on minimizing risks by modifying the design, materials, and processes to reduce the potential for accidents.
Passive Safety Measures
- These measures rely on simple physical principles to prevent accidents without requiring manual intervention.
- Example: A pressure relief valve that automatically allows excessive pressure to escape, preventing vessel rupture.
Active Safety Measures
- Active safety measures require human action or machinery activation to control hazards and mitigate risks.
- Example: Emergency shutdown systems that must be activated manually in response to abnormal operating conditions.
Procedural Safety Measures
- These measures involve established procedures and practices to prevent accidents and incidents.
- Scenario: Regular safety drills conducted to ensure that personnel are prepared for potential emergency situations.
Passive Safety Measure in Batch Chemical Reactor
- The use of a double-wall reactor design that contains a leak within the outer wall as a means to prevent hazardous exposure.
Purpose of Active Safety Measures
- Active safety measures aim to detect and control hazards, providing fail-safes that activate during emergencies to prevent accidents.
Purpose of Procedural Safety Measures
- Procedural safety measures are aimed at ensuring safe operation through guidelines, training, and protocols that enhance risk awareness and response in various scenarios.
