I contacted the manufacturer and was told that those events are rare but do occur. Mercury spills on an FRC field will close down the event.

Per Q/A, they were legal in 2006, 2009, and 2011, and illegal in 2010. The reason for them being illegal in 2010 was not because of mercury, but because any type of slip ring was not legal in 2010. There have been no relevant Q/As since 2011.
