Explosion Venting Panels versus Explosion Doors ; Pros and Cons?

A vent panel or a venting panel once it fires has to be thrown out; a vent door can be self reclosing probably requiring only new seals.  The explosion venting door once it closes will retard the ingress of oxygen to fan the fire but be aware it may require integrated vacuum breakers.  If you’re using a CO2 extinguishing agent to inert the fire especially on a silo, there is no point in using a vent panel as the agent will just be drawn out like a chimney, making the CO2 useless.  Cost versus intended purpose; always do a thorough risk assessment and ask your supplier.
If you have any more questions, please feel free to contact me and I will be happy to respond.
