A Tyvex suit is not appropriate for Ebola. Asbestos, dust, oil and caustic chemicals, OK, in many instances. Cost= $250 a case. One biohaz suit cost= $1350, at least, and the cost of SCBA is higher yet (I’ve been out of the business for a while so prices probably went up). But if it makes them FEEL better, OK. Problem is, they’ll probably spread it faster because they think they are able to take greater chances.
If ebola goes airborne, true.... If it goes airborne it is an extinction event.
Right now it is not. It is still fluid droplet based like flu or the cold. For that Tyvek (Notice the spelling) is fine.
SCBA breather is not required, and N95 is reasonably good. N100 masks would be better, but too costly. So if the N95 mask is good enough so is Tyvek. It is substantially less porous than a N95 mask.
The suits are only for the when the SHTF situation.
See my previous post and the protocol being used in med centers in Africa. That protocol is allowing them to interact with the most virulent patients and not get it. The only thing is don’t break protocol. Notice they are using N95/P95 masks. SCBA is not required.
