U.S. EPA Residual Risk  – Trichloroethylene and Beyond

Are stronger nation-wide controls on worker exposure to trichloroethylene (TCE) likely in the near-future?  Recently, the U.S. EPA held an “Expert Public Workshop on Alternatives and Risk Reduction Approaches to Trichloroethylene (TCE) Use as a Degreaser.” I participated both as an attendee and as a presenter.

SUR/FIN on a Tsunami

There is a positive  “sea change” of growing optimism in the product surface finishing industry. At the recent SUR/FIN conference, rather than the attitude “alas, there’s a whale sitting on me, I’m stuck under water, what can I do?” we heard, “oh!, there’s a whale sitting on me, so I’m […]
