Dan, Safely, yes. With certainty, maybe. Just test them with an ohmmeter as you would for any NPN transistor - base to collector resistance, base to emitter resistance - some resistance with the probes in one direction and no conduction in the other direction.. You may find the resistances lower than with them out of circuit, but it should give you some idea about their health. If they show zero ohms in both directions, they are for sure bad.
