I have used 293 cells for more years than I care to mention. I have used 
no special precautions with them. Rarely, do I even wear gloves. They do 
not harbor infectious adenovirus (except if you infect them). I am not 
aware that they contain any human retroviruses.  I would treat them like 
you treat HeLa cells except that they don't attach as well to the dish. 
ATCC probably gives a disclaimer with any cell line that they ship. 
If you have any other questions about them, please e-mail me.
