MIL-HDBK-1191
6.9.7.3
Miscellaneous Equipment Considerations
a. Secure equipment or shelving not required to be moved from
location to location to a partition. Equipment with doors should have a
positive latching device that operates automatically when access to the
equipment or shelving is not continuously required.
b. Blood bank, drug storage, critical refrigerators, freestanding
incubators and centrifuges, should be secured.
c. Secure sequential multiple blood analyzers and other fragile
laboratory equipment. Anchor related shelving, and provide lips and face bars
as necessary.
d. Wheeled Equipment. Wheeled equipment should have wheel locks
and should be assigned a specific location when not in use. Wheeled equipment
should be provided with closets or alcoves, whenever possible, to limit
rolling. Portable equipment should be stored in recessed cabinets which are
secured to partitions, whenever possible.
6.9.7.4
Supply Storage. Supply cabinets should have either plastic or
tempered glass in sliding doors, and the doors should slide closed
automatically. Open shelving should have a shelf rim which precludes supplies
being shaken from their storage position.
6.9.7.5
Medical Gas Bottles. Metal boxes attached to the floor and
equipped with double chains should be provided for medical gas bottles.
Wheeled carts carrying oxygen or other medical gases should be equipped with
wheel locks and chains for fastening to walls.
6.9.8
Architectural Systems.
6.9.8.1
Lighting Fixtures. Provide independent hangers at diagonal
corners of lighting fixtures installed in suspended ceilings. Avoid use of
pendant fixtures; if used, they will be of earthquake-resistant design. Use
positive locking devices to install surface-mounted and recessed fixtures.
6.9.8.2
Ceilings. Avoid the use of large areas of lay-in type acoustic
ceilings. Such ceiling construction is not inherently earthquake-resistant
and will become progressively less earthquake-resistant due to failure to
replace hold-down clips during maintenance procedures. Avoid the use of these
ceilings in egress and triage areas. Where such ceilings are used, use
lateral bracing and runners tied with wires rather than clips. Do not attach
the ceiling to the surrounding walls.
6.9.8.3
Computer Room Floors. If computer room floors are used, they will
be adequately braced to resist seismic motion.
6.9.8.4
Partitions. Provide appropriate backing plates, blocking, studs,
blocking and bracing for partitions which support cabinetry, storage racks,
shelves, bins, and lockers. In a relatively flexible building, limit
partition damage due to interaction with the frame by anchoring each partition
to a single Structural Design member and allowing movement at the other edges.
6.9.8.5
Facing Materials. Brittle facing materials such as ceramic tile
or glazed masonry suffers extensive damage during earthquakes and will be used
only when necessary to meet medical functional requirements.
