The 4 GHS hazard pictograms for TMAH - red bordered diamonds for toxicity, health hazard, corrosive, and environmental toxicity

We've added a new Fact Sheet to the Chemical Hygiene Plan!  

Tetramethylammonium hydroxide (TMAH) is a highly hazardous chemical used in some research labs on campus.  Due to this chemical's unique hazards we've created a Fact Sheet to explain the risks of exposure to TMAH and how lab workers can protect themselves.  If this is a chemical in your lab, make sure that it's in your Chemical Inventory, and contact EHRS for assistance with creating a Hazard Control Plan for its use.
