If the explosion is ventilated within a building there is also an enhanced risk of a
secondary explosion occurring, caused by the pressure wave from the primary explosion
dislodging dust from walls, beams and other surfaces. The result of such a secondary
explosion could be catastrophic.
General recommendation.
It is always recommended to place filter units outdoors when they are fitted with explosion
relief ventilation panels. If indoors, then only a short straight duct should be fitted, to
ventilate to an external safe area.
