Well, yes, that can be a problem, but I think SCRs can be shut off by
changing the bias of the gate circuit.

I don't think the above is the case for SCR's. Once triggered into
conduction, they stay in conduction untill the current flow thru the
device is interupted external to the device. All the SCR's that I
have ever used seem to work this way. You mileage may vary.....
