Work Safety for CRNA'a

I am a first year student and dont know it all yet (by far) but with many places in the hospital there may be radiation used during cases, in which case you would use the appropriate lead shields (unless pregnant or some other reason- you would leave the room if there was another anesthetist who could relieve you). I believe most gases are contained within machines and discarded appropriately- there are inherent risks which is why you spend alot of time learning how to properly operate machines and deal with various gases, hazardous materials. If there were always dangerous substances just floating around in the OR, you wouldnt have enough healthy surgeons, anesthesia, OR nurses, staff etc to actually do any procedures- jmho
