The Shell DEP 34.17.10.30 Feb 2011 requires that HVAC units shall not be placed on the roof of such buildings so as to mitigate the consequence of flying debris during an event.
Will it suffice if the HVAC unit is shielded from the blast pressure by having the parapet wall of adequate blast strength extended around the roof?
In the case that I have, there are 2 nearby structures involved, 1 an electrical and control equipment room that requires to be of blast resistant design and another which is the plant which is open on all 4 sides with a sun shade panel for 2 m length from the top. The plant building is 6 m high. In the event of a blast the panels on the plant building is likely to be thrown off farther than the HVAC units atop the E&C equipment room.
The control building needs to be protected in an event as it comes under the definition of an occupied structure.
How would one see the case above considering the safe guard required against flying projectiles.
