14. Back-up: sector 12 evacuation
Message from P. Cuikshank
Following the insulation vacuum consolidation works in the S12 arc, the first QRL subsectors were being evacuated from atmospheric pressure with mobile pumping groups equipped with large capacity rotary pumps.  One of these units, placed near to Q31L2, and evacuating the QRL subsector D malfunctioned shortly after start-up. The exhaust filter, designed to condense oil mist at the pump exhaust failed to operate – the cause of this malfunction hasn’t been investigated yet.
The pumping group was started up at 09:38 and shortly after, the VSC support staff moved to another part of the tunnel. A smoke cloud (oil mist) became visible to non-VSC technical staff working nearby, and a local fire alarm was manually activated.  From logged data, the pumping group stopped evacuation of the QRL at 09:54 - I understand the electrical supplies were interrupted following the fire alarm (tunnel lights went out).
During the intervention by the fire brigade, the pumping group was identified as the cause of the problem, and the oil mist cleared. During an afternoon visit to the pump location, there were no detectable traces of oil on any surface, including in the directly path of the exhaust port. A similar incident occurred during LHC installation.
The pumping group will be brought to the surface and the malfunction investigated. An immediate action is that similar pumping groups in use in the tunnel shall be monitored by VSC during the first 20 minutes of high load gas flow.
The above inputs will be integrated into a formal report.
Apologies for the interruptions & inconvenience generated by this incident.
