Formaldehyde Disposal - (Mar/18/2011 )


We want to use 4% paraformaldehyde for fixation of cells onto slides.

Can someone go over:

Proper disposal steps
Proper response in cleaning up a spill.

Thank you so very much for your time and response.


Which country are you in? This will affect the proper proceedures and safety limits... have a look at the MSDS too.



We are in US, California, Santa Cruz


The best course of action would be to contact your institute's industrial hygenist. Failing that, you could call your municipality's sewer utility directly.
