I live in an attached brick house. My garage is in the first floor of
the house. I needed some outlets in the home office room that is
adjacent to the garage, so I ran EMT conduit on the garage side of the
(cinder block) wall and then drilled through the wall for each outlet
on the other side.
This has left some crevices for air to pass through. It isn't really a
big deal, but I do keep a car in the garage. I was wondering if any of
the expanding foam products would be OK to fill the holes. I'm
guessing that at least a little of it might be able to get into the
electrical box, through some unused mounting holes. Is this a problem?

Well, the stuff is flammable, it might not be a problem but why not use
a product that wouldn't have the concern? Like caulk. How much or a
gap is there?

Wouldn't code require fire separation?

At the very least he just punched holes in a firewall. Fire sealing would be
appropiate.

Hi,
I'd pack it with fiberglass insulation.
