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.
