ARCHITECTURAL AND ENGINEERING DESIGN REQUIREMENT
LEGEND and NOTES
General, Isolation Rooms. For Disease Isolation Bedrooms, bedroom to
be negative to anteroom, anteroom to be negative to corridor. For
Protective Isolation Bedrooms, bedroom to be positive to anteroom,
anteroom to be positive to corridor.
Note that room description and
engineering requirements for BRII1, BRIM1, BRIP1, and BRIS1 are for
Disease Isolation; this does not preclude the provision of Protective
Isolation bedrooms in pediatrics, ICU, or other ward locations when
local conditions dictate need. Protective Isolation engineering
requirements will be the same as for BRIT2.
Exhaust all to outside applicable to process only.
Design in accordance with NFPA 99.
May require vehicle exhaust, CO detection.
When the Using Service intends the routine usage of nitrous oxide in
the DTR, routine being defined as exceeding 5 hours per week, the
following criteria shall apply:
- DTR room air changes shall be not less than 12 total AC/H.
- The room shall be totally exhausted.
- Provide a minimum of one low-level exhaust register, sized to
remove a minimum of 20% of the total room exhaust volume.
- During period of non-use, air change rate may be reduced to 5 total
For projects incorporating brace/appliance fitting or shop
applications, evaluate room and equipment exhaust requirements for
removal of toxic or flammable fumes and dust.
Provide exhaust or fume hoods,and localized exhaust as required.
Verify computer heat load requirement.
Provide adjustable (to user) humidistat within the room.
Provide adjustable (to user) thermostat and humidistat within the
HEPA Filtration of room exhaust is not required if designed to
discharge away from public areas (sidewalks, eg.) and such as to
avoid reentrainment into any building opening or outside air intake.
Exhaust of TB isolation room, toilet, and anteroom to be by dedicated
exhaust system, ie., exhaust system serving only TB isolation
room(s). Isolation room pressure to remain constant - not switchable
from Disease Isolation mode to Protective Isolation mode, or vice
HEPA Filtration of supply air required.
