As udarrel says, make sure you don't exceed the rated amps for the
motor. I have a few of these furnace blower "fans". You need a
bit of framework to hang on to the squirrel cage anyway, I use a
piece of peg board across the non-motor side of the housing. This
is usually enough to get the amps down to a decent level.

I have a furnace blower and I'd like to convert it to a
workshop
exhaust fan. Not entirely sure how to wire it. Motor says its
120/240V. Can I just wire it directly up to household current?


Yes, either 120 volt or 240 volt, but you need to see which
voltage it's set up to run on and either use that voltage or
change the wiring on the motor
Many furnace blowers are engineered to work within specific
static pressures.
When they are operated outside the ductwork, some blowers will
overload unless you rig-up some static resistance.
Use an amprobe to see if it is drawing too many amps; some
blowers will bog down, it all depends on how they were
engineered to operate.
