IncLoc: West Factory 2nd (Semiconductor Fab A7)
At five o'clock on December 20, Electrical failure shut down semiconductor fab A7. Workforce injuries were negligible, and mainly resulted from stumbling in the dark. However, a high-voltage power spike burned out most of the primary equipment. Replacement is possible, but will take three weeks or more, even if we divert resources from toy production. ProdCoord reports that we can still meet our quota, as long as the other two fabs remain functional.
Investigation revealed clear signs of deliberate sabotage, (see case file 785236-B for details) making this the seventh such incident in the past three weeks. The backup generator which was used to supply the additional voltage was activated by a timer. Note that if the timer had been set to go off any earlier, this year's operations would have been crippled. We can probably assume a degree of restraint on the part of the saboteur(s).
Following the initial report, emergency crews were dispatched to check the building, establish temporary lighting, and escort the workers outside. (Medical assistance was largely unnecessary.) IntSec officers took statements, and removed the workers to the quarantine dormitory for further questioning. Struct-Maint crews were sent to restore power to the fab, and reported evidence of tampering to IntSec. (See case file 785236-B for details.) Cleaning and Struct-Maint crews were also remanded to the quarantine dormitory for further questioning. IntSec Agent 623488 was assigned to gather documentation from Struct-Maint and Cleaning.
Initial investigation has failed to turn up any substantial leads. The fab workers came up clean, and their involvement seems unlikely; none of them appear to have had the opportunity, and they all have high Loyalty ratings. Cleaning seems similarly unlikely to be involved; personnel there tend to score lower on Loyalty, but also lack the technical knowledge for this sort of specialized disruption. A perpetrator in Struct-Maint seems most likely, especially as the maintenance logs for West Factory 2nd have clearly been altered. (See case file 785236-B for details, or 785236-F for a copy of the document itself.)
Unfortunately, owing to the alterations in the logs, further investigation there would require quarantine for all Struct-Maint crews, if done properly. Such action is obviously not feasible at this time, but will be pursued as soon as Delivery Day is complete.
