Possibly more importantly, the "venting" is not what you'd call a gentle breeze. "Explosive atmosphere replacement" is a better description. Solid things will go airborne at speed.
Huh, so I was curious and looked up demonstration videos. Some of them looked similar to an indoor hurricane and some of them looked like a gentle breeze. The classroom-style (small room with a few Inergen bottles) demonstrations had the biggest effect and the actual datacenter tests just looked like a small breeze. Maybe in an actual datacenter the Inergen:open space ratio is substantially smaller than demonstrations in a small room?
