What about our health and safety concern of inhaling and ingesting diesel exhaust to hook up the hose?
This is one of the biggest advantages of the apparatus-mounted system - it direct source captures the toxic diesel exhaust at the tailpipe. Therefore, it does not require diesel exhaust inhalation by personnel while hooking up a hose as the rig is backed into the station. This is commonly referred to as the so-called "bend-over for the back-in" problem.
