Hi all --
This is just a note to let everyone know that Ed, Mahnaz, Uli, and I
approved the use of the PSE300 and PSE300SF Transene etchants at
wbgeneral and wbgaas, with the following provisions:
1. PSE300SF and PSE300 contain ethylene diamine, so any possible
contact with concentrated sulfuric, nitric, or other oxidizing acids
must be avoided.
2. When planning to use these etchants, the entire bench must be
reserved for the period of use, so that no other labmembers will plan to
share the bench.
3. When using these etchants, yellow Hazard tape should be attached
across the front of the bench, with a note, to warn others from sharing
the bench. The bench must be enabled.
4. Used etchant and first rinse should be collected locally in
chemically compatible waste containers and labeled appropriately as
hazardous waste. They should be placed in the appropriate area of the
chemicals pass-through for disposal.
As PSE200 is a KOH formulation, it is approved as per standard KOH
