Chemical Hazard Analysis: Prevention and Mitigation
Bromine Exposure
Hazard: Bromine
Consequence: Bromine Exposure
Preventative Safeguards:
- Routine System Pressure tests
- SHE critical Procedures
- Kynar Lined piping/glass vessels
- Hose inspection/integrity
- Equipment Strategy
- Safety Critical Instrumentation
- Materials of construction
Mitigating Safeguards:
- Bromine Detectors
- Automated Trip systems
- Containment Sump
- Emergency Response
- PVC containment pipe
Situations Leading to Scenario:
- Hose failure during Bromine Unloading
- Leak from Bromine Facilities/piping
- Long term corrosion of pipe supports
- Liquid overfill
Isoprene Storage
Hazard: Isoprene Storage
Consequence: BLEVE (Boiling Liquid Expanding Vapor Explosion)
Preventative Safeguards:
- Safety Critical drain procedure
- Over pressure/Vac protection
- PSV N2 Sweep
- Redundant level instruments
- Inspection program
Mitigating Safeguards:
