Consideration should be given to modular construction, versatility,
relocation, and incorporation of shielding. Structural support should be
provided to accommodate any anticipated loading resulting from
shielding. The type of shielding used and its placement should allow for
adequate fire-fighting access.
Enclosure specifications should address the following standardized features,
Windows and mountings.
Windows should be appropriately sized (and as small as
practicable) and located to provide operators with visual access
to the enclosure interior.
Windows should be constructed of noncombustible or approved
damage should be considered.
The use of MylarTM -glass laminates should be considered for use
as viewing windows and lighting fixture covers in hydrofluoric acid
Windows should be designed to minimize the risk of releasing
contamination to the working area during window replacement.
Window material should be selected based on specific process,
combustible loading, and radiological safety considerations.
Glove ports (size, location, and height).
Glove ports should be located to facilitate both operations and
maintenance work inside the enclosure.
Gloves should be flexible enough for operating personnel to
access interior surfaces and equipment.
