Pass through chambers provide an easy way of moving supplies and materials in-to and out-of the Class III BSC.  There are a few options to consider with these devices.  To begin with, their interior surfaces should be coved for ease of cleaning, and the exterior of the chamber should not extend into an area [...]

What type of airflow should be used in a Class III BSC?  Is higher velocity better?
            Unlike Class II BSC which employs laminar flow to protect personnel, the Class III BSC does not have an open sash in the front, hence does not require laminar airflow to provide personnel protection.  The main consideration for laminar [...]

The post from January 10th on Mobile and Modular Laboratory Platforms generated an interesting question.  The question was, ‘If we can build the BSL-3 lab with local tradecrafts, but do not think there is local experience in HVAC construction and controls, is it possible to purchase the HVAC system in a prefabricated package for delivery [...]

         Three events have come together in the past few years that codified a need for rapidly deployable, mobile and cost effective containment equipment.  First, there was recognition that many regions and countries in the world did not have adequate infrastructure, reliable power, or primary containment to provide a safe environment when working with emerging, [...]

I was at a meeting recently when someone asked, ‘What are mobile and modular BSL-3 labs and when should they be used?”  It is a good question that comes up often.   Deciding  which platform is the best choice depends on the institute mission, size requirements and in the case of mobile labs, the local road conditions.   For example, if [...]

In the 1950’s when Class III BSC became widley used in the nuclear and defense departments the primary focus for design was on absolute containment, with little attention given to ergonomic/user comfort.  Class II BSC became popular in the 1970’s and provided the user with an alternate means of primary containment.  While Class II BSC do not provide the same level [...]

The other day I was asked about glove selection for use in a Class III BSC and whether there were options other than butyl rubber.
             Gloves are supplied in a variety of materials from several manufacturers.  These materials include neoprene rubber, butyl rubber, and hypalon and have differing permeability rates with various chemical compounds (including [...]

    There are several technologies typically used to transfer samples, materials and waste into and out of the Class III BSC. These include dunk tanks, pass through chambers, double door autoclaves and rapid transfer ports (RTP). 
    Dunk tanks allow for the passage of potentially contaminated materials out of the BSC without breaching containment.  It also [...]

Decontamination is a broadly used term that describes a number of techniques or strategies for reducing or eliminating the presence of hazardous microorganisms and biological toxins from various surfaces, materials and equipment.   Decontamination is important from a safety perspective as well as preventing cross contamination and maintaining the integrity of the work.
 Critical elements involved in [...]
