Recent deliveries of 10 x TBE solution from Life Technologies have had a label attached to the bottles which states:

"Contains TRIS Base, Boric Acid      Danger

causes skin irritation

causes serious eye irritation

May damage fertility, May damage the unborn child"

While the available MSDS for the powdered TBE mix does carry similar warnings, the MSDS for 10 x TBE states that there are no special measures required and that generally there is no irritation risk.

Is anyone aware of changes to the hazard status of 10 x TBE solution and are special precautions/personal protection required when handling it ir the 1 x and 0.5 x dilutions in use in the lab?
