The chief purpose in facility siting and the blast resistant design of structures in the protection
and safety of building occupants. Hazard mitigation is the primary driving force behind the architectural and structural design concepts for control rooms, operator shelters, offices and other occupied buildings in a petrochemical facility.
Blast pressures from accidental explosion can cause serious bodily harm and even death. However, the number one cause of death in a blast event is injuries resulting from building component failure or death. Therefore, to mitigate the hazards of accidental explosions, the blast resistant building area engineered to shield the occupants from the blast pressure wave, and resist the loads without collapsing.
