The interesting thing here is that the boundaries are drawn by the employees based on their convenience rather than any valid hazard or risk assessment procedure.
If there are aerosolized microorganisms of concern then the space inside even a hard-walled lab has to be questioned. My experience is that in cases where lab design has unfortunately allowed for the "open concept", an administrative barrier or demarcation can be acceptable so long as PPE "wandering" is rigidly enforced from happening, hand washing after lab work occurs and airflow is supplied over cube spaces and exhausted from w/in actual lab space. That said, I wouldn't give in unless you have to and preferred is what Eric states. However, picking your battles and having credibility when you really need it is also at play. Requiring hand washing before eating is better control than a wall and I'd start with that skirmish then move to the battle for money to segregate spaces better. Remind your local "lab architect" that we prefer leaving open concepts to the homes on DIY network.Steve Crooks, MS, CIH, CSPPeople, Property & Env. Protection, Inc.

I'm hoping to get some advice regarding an ongoing issue in some areas of my company-
It seems straightforward enough that food and drinks are not allowed in lab areas, but the problem keeps cropping up. A BSL2 lab has cube space between two BSL2 work areas. The walls are only half-walls but the residents of these desks want their food and drinks and the manager of the lab put tape down to say the BSL2 areas are outside of the cube area and that it is reasonably safe to have food and drinks in the cubes. I thought the rule was that the dividing walls had to be floor to ceiling. Anyone else have a similar situation in conjunction with a BSL2 work area?
Another lab used to not have chemicals, and people would drink/eat while at computers. Now there are chemicals stored and used in the lab, and of course people are trying to still eat/drink. We (safety) put a stop to that, but then they put tape down and made an area that is =E2=80=98no chemicals or work materials' allowed and they put a table, chairs and a mini-fridge. My opinion is that food and drinks should not be allowed in this lab at all, although maybe there is some way to permit closed drink containers in a designated area? But the mini-fridge seems out of my scope of allowable items in a lab that also stores/uses toxic chemicals. Of course I've reviewed the regulations and they support no food/no drinks in at least the case of the chemical laboratory. But are there allowable exceptions? Right now my views are being considered employee unfriendly, and while I'm not worried about that, I want to make sure I've researched the situation thoroughly so that I'm not being overly strict. (Note: my company safety officer is "new" to safety-)
Any information or specific instances/experiences you can share with me would be most helpful and appreciated.
