Yes, I have had experience with this system storing chemicals, specifically 10% neutral buffered formalin in “Tupperware” equivalent containers.  We changed containers for better tight-fitting lids, but continued to have exposures >AL, due to the lack of airflow through the racks.  Spot ventilation was impossible, therefore had to rely upon dilution ventilation which if you check the design – makes this system problematic for any chemical storage.  My problem is that it was already paid for, installed and significantly used.  I would recommend considering the costs above initial purchase, to include: Occ Health Exams, routine IH monitoring, etc.

Hi All:


Does anyone have any experience with using this type of system for chemical storage?


If you do have experience, do you have a rough estimate of cost?


Thanks very much,
