| Considered part: Transfer duct of supply tank from Diaposime to coils | ||||||||||||
| Material: Diaposime B117 | Activity: Transfer continuously at a rate greater than that of NaCl Destination: Streamers | |||||||||||
| Source: Diaposime B117 Tank | ||||||||||||
| Operating parameters: Pressure and temperature | ||||||||||||
| N˚ | Word guide | Element | Deviation | Causes | Consequences | Barriers security | G | P | R | Events | Correctives action | Resp. |
| 1 | Do not do | Diaposime B117 (D) | No Diaposime B117 | Empty supply tank | No flow of D in the coils. Explosion | None apparent | 5 | 0.133 | 0.665 | Unacceptable situation | Plan the installation for the B117 diaphragm tank of a low level alarm. As well as a low threshold trigger for shutting down the NaCl (Salt) pump. | CL, CE |
| 2 | Do not do | flow D > flow Salt (S) | No transfer takes place | Pump D stopped, duct clogged | Explosion | None apparent | 5 | 0.133 | 0.665 | Unacceptable situation | Flow measurement of material D, as well as a low level alarm and triggering of the S pump in case of low flow | CDME, CDMM, CE |
| 3 | More than | Material D | Material tank D full | Filling the tank from a tank, so that the ability is insufficient. | The tank is going exceed the limit filling | None apparent | 2 | 0.133 | 0.266 | Acceptable situation | Anticipate an alarm high level if not determined previously | CL |
