How are things Changing?
Traditional Approach
• Focus on DSEAR and controlling ignition sources
• Emphasis on preventing air ingress into gas space
• Post digestion sources are not contained to reduce explosion risk
IED
• Control of methane emissions
• Increased covering post digestion
• New technologies with new risks, e.g. vacuum degassing of digested sludge
• Leak detection and repair (LDAR)
Process Safety
• Control of major hazards and environmental accidents
• Focus on low likelihood, high consequence
• Systematic framework to map the progress from initiating event to incident and identify all controls and mitigating barriers
