Which is safest:
CaO4S indicating or non-indicating
or
Ca Cl2

to use as a dessicator.

I have evaluated the other options such as the
P2O5, Zeolite (Molecular Sieve), and Silica Gel -
these products are either too dangerous to ones
health and required gloves etc., or are too dangerous
if accidentally exposed to water.

Its down to the following:

CaO4S indicating or non-indicating (Drierite)
or
Ca Cl2

The Drierite seems to be the best option however
poses higher health risks or may.  Please help me
choose one.

Thanks
