Prepare for EPA's new rule for trichloroethylene

 

In December 2024, the U. S. Environmental Protection Agency (EPA) finalized a new rule under the Toxic Substances Control Act (TSCA) to protect workers, the public, and the environment from the risks of trichloroethylene (TCE) exposure. While certain portions of the rule are currently under legal review, most of its requirements are still expected to go into effect starting on September 15, 2025.

Lessons learned from a chemical fire

 

In December 2024, a group of undergraduate research students conducted an experiment in a shared research/shop space following a standard operating procedure (SOP) they had recently updated. One of the students had performed this work before; no supervisor was present.   

The experiment involved heating a chemical mixture on a hot plate inside a fume hood. The mixture overheated, ignited, and caused second-degree burns on a student’s hands. The student received medical care and has recovered.

Gear up for summer lab work

 

Summer in Seattle means hiking, biking, kayaking and ... lab work. Yes, many of us spend gorgeous summer days working in the lab. While it's fine to wear shorts, skirts, sandals or flip flops outside, wearing these items in the lab can expose you to hazards. Proper lab attire ensures your skin is covered and protected.

Even if you aren't working with hazardous materials that day, your coworker might be, so always dress to protect yourself. We recommend keeping an appropriate change of clothes and shoes in the lab so you are never without the right gear.

Updated ABSL-1 waste disposal procedures

These updates were made to align with current regulatory requirements and best practices.

Updated ABSL-1 waste treatment and disposal procedures

ABSL-1 animal waste will now be packaged and sent for off-site incineration.
