Hi ARMS 2132 Researchers,

Good news! REM has approved us to use the following chemicals again:

· Nitric Acid (You are still prohibited from making Nital. All Nital use must be from a commercially made solution.)

· Hydrofluoric Acid (Note: You will not be given the key to the HF cabinet without your HF buddy and proper training.)

· Perchloric Acid

· Base Piranha Solution

At this time, the MSE Safety Committee plans to continue to keep all acids, oxidizers, and nital in the locked cabinets. You are still required to submit a hazard assessment (HA) and SDS/SOP in order access chemicals in these groups.

Stay Safe,
