DOE-HDBK-1132-99
rapidly remove heat produced by fire to prevent or minimize
pressurization of a process confinement and
rapidly extinguish a fire to minimize the loading of ventilation
system filters with combustion products.
(See DOE-STD-1066, Fire Protection Criteria, and DOE-STD-3020,
Specifications for HEPA Filters Used by DOE Contractors.)
The introduction of the extinguishing agent in a way that does not result
in overpressurization of the confinement barriers.
Provisions to collect liquid agents when a wet suppression agent is used.
Enclosures (as primary confinement). Enclosures are physical barriers
(e.g., cells, cubicles, gloveboxes, fume hoods, conveyor tunnels) that, together
with their ventilation and operating systems, prevent the release of radioactive
or other hazardous material to the work space or the environment. Accordingly,
their structural and confinement integrity is a design consideration. [See the
American Conference of Governmental Industrial Hygienists (ACGIH) Industrial
Ventilation: A Manual of Recommended Practice (ACGIH 2090); American
Society of Mechanical Engineers (ASME) Code on Nuclear Air and Gas
Treatment (ASME AG-1); and Energy Research and Development
Administration (ERDA) Nuclear Air Cleaning Handbook (ERDA-76-21).]
Enclosures should be designed to prevent exposure of personnel to airborne
contamination and to implement ALARA concepts to minimize operator
exposures. The enclosure system, including its internal and external support
structures, should therefore be designed to withstand the effects of normal
operating conditions, anticipated events, and accidents. Criticality
considerations, when needed, should include water or other liquid sources,
potential liquid level in the enclosure (during operations or fire fighting), drains to
limit liquid level in the enclosure, and liquid collection in depressions, walls, and
other areas.
