I don't see much danger in that job, unless it involves running a new
electrical circuit.

Remember they are installing an opener, not the door. Installing a
door often involves working with a set of springs that can be dangerous.

So which is it? Dangerous? Not dangerous? Is 110v. electricity dangerous?
Are those springs dangerous? Do they need tweaking? (not a job for a
newbie that can't follow the directions for putting up the opener) The
track is VERY EASY to tweak.
