Peroxide CAN BE kinda scarey stuff.

Peroxide, by itself, as received, in the original container, and kept under
100, or so, is nothing to be scared of.....however, when mixed with Copper,
even in small amounts, it can go away (decompose) into water and Oxygen gas
and if mixed with relatively large amounts of Copper, as it is in an etch
replenisher, it can be more exciting than you want it to be.

However, remember also, that with the correctly designed introduction
equipment, this stuff can run forever with not a hitch, and is and has been.

The key is to talk to people who have designed this kind of stuff, they have
figured it out real nicely.
