Incident Commander Immediate Actions
1. Containment & Dike Verification
Verify bund wall capacity for at least -- m³ (110% tank vol). Ensure secondary containment valves are closed.
2. Shell Cooling Ring Activation
Start water deluge on exposed dry shell plates at ≥ 10.2 LPM/m² to prevent structural thermal collapse.
3. Gentle Foam Blanket Application
Apply finished foam via fixed foam chambers or semi-subsurface monitors for a continuous runtime of -- mins.
4. Emergency Bottom Pump-Out
Route product out via bottom discharge manifold to adjacent spare storage before liquid reaches hole elevation (-- m).
