At the Portsmouth Regional Hospital Ideal Shield heavy guardrail was installed at the truck dock to keep trucks from backing up into the building. This was needed for several reasons - one being the need to protect the dock from damage as multiple trucks hit it but more importantly surgery takes place on the second floor and any movement in the building could put a surgery in jeopardy.
This piece of guardrail is placed far enough away from the building to stop the truck trailer from hitting the wall and is strong enough to withstand multiple hits. The rail was also modified to increase the strength of the heavy guardrail; a third post was added and the unit was installed in 46″ deep floor sleeves.
