1 Scope
This document applies to air shutter frames and air doors for ventilation structures which are to remain
functional after the passage of explosions with overpressures of up to 2 bar.
Ventilation structures are protective systems to provide the ventilation flow after the occurrence of an
explosion such that the effects of an explosion on the ventilation system can be limited and adequate
possibilities remain for escape and rescue.
NOTE These structures may be used when ventilation studies indicate that the air flow in the work place would be
reduced considerably providing no safe escape for workers in cases where the structure is destroyed. Explosion proof
ventilation structures will be individually evaluated fo
