Retention full of ammoniadrainage of ammonia in the retention
Presence of people People injury B 4 Remove the dangerous phenomenon
- Drainage by a truck equipped with a pump : tank drainage procedure to study with OMRIN to define the means for protection- The floor marking of the danger area is recommended- Leakage detection with flashing light and horn visible before being in the ammonia area (position approved by OMRIN)- Three detections in the area (retention, tank roof and truck unloading)- Two safety showers with eye rinsing : one in the retention, one in unloading area- For maintenance intervention on the pumps, wearing a mask is strongly recommended
