I was thinking about getting some foam in a can to fill an open

Just use it. Don't forget these labels have to cover people who may
work with these substances day in, day out and are to protect the
manufacturer for the 1 in 1000 or those that have a problem.
Occasional exposure for short periods is almost zero risk.

Just make sure the area is ventilated, use the stuff and leave the
room.
I was worried, as I have just spent three weeks in hospital, for
respiratory troubles. So warnings about breathing problems got my
attention.

My big beef about spray foam is it non re-usable-ness ( I just made that word
up) Basically use it once and next time its all blocked up. I've tried
various solutions but none are reliable. I had a small job to do for which it
would have been ideal but not at the cost of a whole tin's worth

I've managed to keep a foam gun going for some years now, just cleaning
between cans with acetone. Used regularly for small jobs, wouldn't be without
it.

2 things. Wear gloves. The warnings about skin contact are real. Never noticed
fumes. And remember to close the valve when you've done - forgetting to do
that killed the first gun.
