Shannon:
I've never seen anyone use a respirator for coating with FO and pt/pd. It's
a saturated, not-very-volatile solution and very unlikely to end up in your
lungs.
Some people use a dust filter mask when and if they use a blow dryer to dry
the paper on the theory that it will prevent small particles of dried FO and
platinum from ending up in your lungs. I just use a homemade drying box made
from a window fan in a well ventilated, dark area away from the coating
operation.
