Safety is paramount in the design.
The dispenser is designed and automatically operated such that LNG is never present when the vehicle driver is inserting or removing the fuel hose from the vehicle. The significance of that fact bears repeating. The only opportunity the driver has to accidentally come in contact with LNG is when fueling an LNG vehicle while handling the fuel hose. Furthermore, the lack of potential exposure greatly reduces the need for obtrusive protective clothing or other gear. Let's not forget station aesthetics.
