Yes, how do you think they would leave otherwise? You can see earlier in the video they walk into the facility without a hose attached.
FTA
"As you move through the lab to a different spot, you unhook, move to where you want to be and grab another air hose."
- ars 10y agoIs the assumption that there are no pathogens in the air, so the air hose is not contaminated? What if there was a release, would it still be OK to switch air hoses, or would they only use internal air at that point?
- smnplk 10y agoThat, I would also like to know. There must be a safety procedure in that kind of event. I imagine they would just detach and leave the lab. Suits are probably made in a way that no air can leave from the air plug
- semi-extrinsic 10y agoI imagine they have special air hose quick connects that purge some volume upon connection. A cursory googling finds Trellchem suits use this type: http://www.cejn.com/products/fluids/couplings-nipples/series-221-breathing-air/ http://www.cejn.com/products/fluids/couplings-nipples/series...
- zbjornson 10y agoThere's a small HEPA filter on the suit itself, downstream of the air hose connection, that filters out whatever may be on the hose connection. You can go without a connection for several minutes easily. The article also unusually describes "thinking about keeping the suit under positive pressure." The vents in the suit have one-way valves, so it really isn't something you need to think about. (-occasional researcher in a BSL4)
