| 10 | Inverted | Transfer Diaposime B117 | Inversion of the direction of flow. The treated water flows from the coils to the tank supply | Pressure in the coils superior to the pressure evacuation the pump | Contamination of tank supply by reflux material from reaction | None apparent | 3 | 0.067 | 0.201 | Unacceptable situation | Provide installing a check valve in driving | CE |
| 11 | Other than | Diaposime B117 | Other than Diaposime B117. Material other that the Diaposime B117 in the tank supply | Bad material in the tank supply | unknown Function of material | Controls and analyzes of the nature of content of the tanker before unloading | 4 | 0.133 | 0.532 | Acceptable situation |
| CE, CL |
| 12 | Other than | Reactor of destination | External leak Nothing happens to boilers | Conduct break | Contamination of the environment and risk of explosion | Integrity of pipelines | 4 | 0.133 | 0.532 | Acceptable situation | Specify that the detector flow proposed is enough fast to release to avoid a explosion | CDME, CDMM |
