Feature Article

Critical Cleaning and Sedimentary Rock

By Barbara Kanegsberg, BFK Solutions

Cleaning processes tend to build up; one layer of cleaning is added to another. The overall cleaning process becomes something that resembles sedimentary rock (or, to the surface of the desk of the Rocket Scientist). Recently, a manufacturing engineer involved in optics fabrication, called to brainstorm and, frankly, to vent. (I am referring to the individual as he – the person could be she.) He saw nagging, intermittent issues with product yield, particularly after changing one cleaning agent. Read the story and my thoughts!

KNOWLEDGE IS POWER

Is all the good stuff going away?
Get involved by September 30! In the June 2020 Clean Source we discussed government activities regarding potential restrictions on some halogenated solvents. This month’s feature article talks to some consequences of solvent substitution.

The following is from a notice received on September 16, 2020 regarding risk mitigation for 1-bromopropane. You probably know the cleaning agent as n-propyl bromide, nPB. “Risk mitigation” can translate to new regulations and restrictions.

“The U.S. Environmental Protection Agency (EPA) is inviting small businesses, governments, and not-for-profits to participate as Small Entity Representatives (SERs) to provide advice and recommendations to two Small Business Advocacy Review (SBAR) panels. There will be one panel for methylene chloride and one panel for 1-bromopropane. Each will focus on the agency’s development of proposed rules to address unreasonable risks identified in EPA’s recently completed Toxic Substances Control Act (TSCA) risk evaluations for these chemicals.”

Don’t ignore this! Go to the link, take a deep breath, dive in, and swim bravely through the acronyms. Be even braver: self- nominate for the 1-bromopropane panel by September 30, 2020.
