explosionIn all buildings with possible or imminent explosion danger is a need for safe emergency ways in combination with explosion venting. Emergency ways to evacuate persons and explosion venting to bring the explosion force to the outside in order to safe the construction of the building against collapsing.
Saving the building construction against collapsing implies that explosion vents must open fully and as fast as possible. Openings must not be obstructed. To prevent damage to the building the explosion force must escape fast, straight and smooth to the outside. For that reason optimal operating explosion vents need a minimal opening resistance. Best should be zero resistance.
Inertia effects of heavy weight covers and /or strong forces to release the cover will increase the collapsing danger.
