Labs get 18 more months to stop using a common chemical
What happened
US environmental regulators are giving most labs an 18-month extension to comply with new rules on methylene chloride. This means non-federal labs now have the same deadline as federal labs to implement new safety programs and record-keeping.
Why it matters
Methylene chloride is a widely used solvent, but it is also a dangerous chemical. The new rules aim to protect workers from its health risks. This extension means labs have more time to find alternatives or implement the required safety measures, avoiding disruption to critical functions like environmental monitoring and university research.
The signal
Watch for how many labs switch to safer alternatives versus those that implement the new Workplace Chemical Protection Program by the extended deadline.
