[3dem] BSL2 vs BSL1

Mon Jul 6 00:32:10 PDT 2020

Hi Sheemei,

Indeed there could be difference between countries. For instance I now work in France at Institut Pasteur where certain pathogens are ranked a class higher then in other countries. It depends probably also on your local safety department of the institute.

There is a general slide deck that TFS has which you should ask for from your local account manager.

For BSL2 i’ll share it here below. In principle it is the labs responsibility to proof to the company that the environment is safe for a service engineer to enter. It is best to do this together with the company your dealing with. There are several decontamination procedures and those often depend On the pathogens you want to study. There are so-called BSL2+ labs where an agreed list of pathogens can be studied with the applied decontamination procedure, where other pathogens are not allowed. Nothing in this is “general”. If a certain lab studies a certain pathogen with an approved decontamination protocol by their specific local safety officers, then it needs to be shared with and approved by the company for their service to come in after decontamination. Hence a lot depends on what you want to put in the microscope and how this is locally dealt with. Most BSL2 however is not that heavy though, the real fun starts at BSL3.

Here the exert of the TFS slide on BSL2:

BSL2 is a containment level where there is the potential for moderate diseases to be transmitted. In this level we can support the tools provided we take some precautions.

   1. You maintain and share a list of viable organisms which require these containment measures within your            lab.

   2. You have a  documented laboratory method for mitigating the risks posed by the use of these organisms.

   3. Your laboratory is registered as BSL2 on our records

Thanks Matthjin, how about if there’s a difference in BSL classification between different countries? For example, the rest of the world that particular pathogen is classified as BSL2 agent while in Netherlands, BSL3. Should there be an increased in maintenance fees?

Maybe this helps

The difference in lab setup between BSL 1 and 2 are not that big. A lab manager can also decide to declare a lab BSL2 for a period of time, then decontaminate and resume operation as BSL1. TFS only charges extra service cost if microscope decontamination procedures are involved and parts can not be taken back. In BSL3 all parts stay in the facility until the lab closes. This means a company can not recover parts and reuse them. This will increase cost. Also decontamination procedures might damage certain parts that need to be replaced (other than the broken parts that needed fixing), which again increases cost. For BSL2 this does all not apply. Wearing lab coats, gloves, presence of a sink, ways to dispose of infectious material, a safety cabinet and modifications to the air flow I believe are required but are all “reversible” back to BSL1. There are no specifications based on disinfecting the inside of the microscope. Best is to contact your local TFS agent, they have a full unit for dealing with this, there are many BSL2 facilities worldwide that house EM.

Cheers

I heard there will be ~10% increase of service contract from BSL1 to BSL2. Has it been applied world wide?

Hi Ruben,
Jaap is correct, BSL2 assumes standard lab practice, lab coat, gloves at the most, but no special safety/decon procedures. And no service cost increase. TFS does not want to deal with BSL3, so that is out of question. Our Krios is classified by TFS as level 2 instrument and my engineers come and go as they like (face mask is required currently… for a different reason). I do not see any cosequences declaring your microscope s BSL2.
All the best,
Misha

Forgot to add that before SVC enters the facility, a wipe down is required. Akin to what you’d do with a lab bench.

Hi Ruben,

Don’t think BSL2 requires that. BSL3 for sure does and requires elaborate decon procedures to be in place. UTMB goes for a SVC visit back from level 3 to level 2. It is then safe to enter.

Hi Jian,

Yes, if we decide to put BSL2 specimens in the microscopes, we have to tell TFS about it, to make sure that their engineers are safe.

Dear Ruben,

Is it request by TFS (FEI)?

Hi all,

Due to the type of samples that we are interested in imaging, it would be advantageous for us to declare our facility as BSL2. This designation, however, has some implications in terms of the paperwork and safety measures that have to be taken whenever service is called. Cost of course I am sure is another factor. Does anyone have experience as to the real implications that have to be considered? It is my understanding that once we declare the facility to be BSL2, every instrument is included in the designation, and it is not reversible.

Any information will be greatly appreciated.

Ruben.
