It is recommended that the pass-through chamber operate at a higher negative pressure than the work
chamber. This will provide the most favorable condition for both product and personnel protection.
The pass-through chamber has an external access door with gloveport. An inter-chamber door is located
inside the work chamber. These doors have a mechanical interlock system to keep both doors from being
open at the same time.
The work chamber viewscreen has key lock latches and two gloveports equipped with gloves to provide a
physical barrier between the technician and the product. The viewscreen is hinged along the top and may be
fully opened for loading or unloading.
! CAUTION !
The viewscreen should never be opened until after the work chamber has been properly
cleaned and decontaminated.
The Baker Company has included ergonomic enhancements into the design of the ChemoSHIELD
®
for
improved operator comfort and safety. A 10
°
sloped front feature and adjustable stand have been
incorporated into the design to improve ergonomics so the operator can use the cabinet comfortably either
standing or sitting without sacrificing safety.
Cabinet Pressure Areas
One of the many features that sets the ChemoSHIELD
®
unit apart from other cabinets is the interaction of
its pressure areas. The whole cabinet is under negative pressure when operating. The pass-through chamber
operates at a more negative pressure than the adjacent work chamber. This allows air to flow into the pass-
through chamber when the inter-chamber door is open to insure product protection in the work chamber.
When the pass-through access door is opened room air is pulled into the chamber thus helping personnel
protection.
The ChemoSHIELD
®
provides better than Class 100 (ISO Class 5) air cleanliness conditions within the
enclosure.
Access to the Work Chamber
For easy entry of apparatus into the work chamber, ChemoSHIELD
®
has a top hinged viewscreen. Its 3/8
-inch shatterproof polycarbonate viewscreen allows excellent visibility, and can be opened fully to permit
placement of large items in the work area.
! CAUTION !
The viewscreen should never be opened until after the work chamber has been properly
cleaned and decontaminated.
While in operation the pass-through is used to bring items in and out of the cabinet.
