Dear CryoEM Community,

We are currently evaluating the risks of becoming BSL-2 CryoEM laboratory and would greatly appreciate your guidance on several safety and setup considerations.

Specifically, we are interested in understanding:

  *   Given that the electron beam can potentially generate aerosols or cause warming within TEMs, what disinfection protocols or measures have you found effective for maintaining biosafety?
  *   Is implementing negative room pressure necessary in a CryoEM lab at BSL-2?
  *   For sample preparation instruments such as the TFS Vitrobot and Leica GP2, is it recommended to place them inside a biosafety cabinet? How about large instruments like the Leica ICE-are there specific safety measures we should consider?

Your insights and experiences would be extremely helpful as we evaluate the best practices for creating a safe and effective CryoEM environment. Thank you very much for your time and guidance.

Best Regards,
Jason NG
