offering, I changed my mind.

This product should not be used under conditions of poor ventilation

according to standard EN 14387) is used. Gas/vapour spreads at floor
level: ignition hazard".

Maybe I'll find some other way to block the hole.

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.

Rigid PU foams are relatively OK although you really don't want to get
yourself sensitised to isocyanate vapours. Flexible foams where the
vapour pressure of the active monomer is much higher are more dangerous.

Just make sure the area is ventilated, use the stuff and leave the room.
