Of course as home inspectors we are very concerned about safety. Some safety items are more serious than others and some can be expensive or cheap to repair.
Main electrical panels are always a concern for safety. With all the power for the entire house running through the electrical panel, it's not to be taken lightly. Look at the picture below:

There is a missing breaker in the area labeled "dryer." In and of itself that's not a problem. The problem is leaving that space open. There are plastic covers that will fit in that area to cover the space, they're called "knock out covers." Kind of hits you like you're in the boxing ring, huh... at least it would if the knock out cover is missing and some one put their finger in there are put a tool in there... zap! Luckily it's an easy fix and the cost is very cheap. Just one of the many items we look for during our home inspections.
I hope this gives you a little more information about a professional home inspection and its value. Be safe out there.

Joseph, the opening is marked "dryer"---would that be a "hand-dryer?":) I hate finding these openings knowing that someone, someday is going to be fumbling around in the dark trying to turn breakers back on.
