Rick,

Be sure not to carry a screwdriver, wrenches and pliers on your inspections. Those tools could be used to dismantle the furnace allowing you to find defects that may not be visible in your "limited, visual" inspection.

What's that? You exclude dismantling furnaces from your inspections? Ahh!

So how is that different?
