Identification of Essential Systems.
Table 6-1 identifies
essential non-structural systems and lists them in order of priority based on
previous post-earthquake experience and input from professional health care
Life Safety Systems.
Fire Sprinkler Piping. Brace sprinkler system piping in
accordance with details provided in NFPA 13.
Portable Fire Extinguishers. Provide mounting brackets for hung
and free standing portable fire extinguishers, designed to preclude
inadvertent release of the extinguisher due to vertical or horizontal
Standpipes. Brace wet and dry standpipes.
Fire Pumps. Protect pumps to avoid damage by falling debris.
Stairways. Design stairways to resist required lateral loads and
insure tolerance to maximum predicted structural design deformations.
Exit Doors. Design exit door frames so they will not deform and
jam as a result of seismic forces.
Exitways. Plan exits and exit pathways to avoid blockage with
debris from ceilings, brittle wall finishes, and glass following a seismic
Special Storage Provisions. Provide special storage equipment or
accessories that are convenient for normal daily use, and functional after
earthquakes. Examples of such equipment are lower profile shelves with face
bars which restrain material on shelves and secure shelves to the wall or
floor; specially designed racks for restraining reserve oxygen and nitrous
oxide tanks; and special bins for storing anesthetic gas containers.
Fuel Gas Piping. Brace piping and provide shutoff valves.
malleable fittings and valves, provide swing joints where necessary.
General. The Essential Electrical System will follow the
requirements outlined in Section 10, Electrical, of this Military Handbook.
Vibration Isolation. Where vibration isolation is not required,
bolt generators directly to an appropriate foundation. Where vibration
isolation is necessary, provide restraining clips at vibration isolators to
prevent failure of the isolation mountings under earthquake vibration
Generators. Where practicable, use generators with integral
radiator cooling systems. Where auxiliary cooling systems are necessary,
install cooling towers or remote radiators at grade level. Brace cooling
towers or radiators and provide special bracing for piping.
