frequently collocated with the break area, but can be broken into smaller spaces to
distribute vending machines throughout a larger facility.
2-220.127.116.11.4 Mechanical, electrical and telephone rooms should be located, and
distributed through the building, for efficiency of function and building distribution. The
main mechanical room should be on an exterior wall with exterior access to a drive for
ease of maintenance, repair, and replacement work. Architectural, mechanical and
electrical disciplines must coordinate size and location of building support spaces to
provide sufficient space for equipment installation, operation and maintenance, as well
as efficient distribution of services.
OMS Functional Relationships
2-7.3.1 An optimal space arrangement for an OMS would have several of the OMS
spaces opening directly into the workbays NFPA 101 no longer allows occupants from a
corridor to exit through another space; any corridors must be arranged to provide the
required number of exits without exiting through the maintenance bays. In addition, any
corridor which leads to a maintenance bay must not exceed required dead-end
distances. Larger facilities should have corridor arrangements similar to those shown
in the Figures in this Section.
The shop office, tools and parts storage,

toilet, storage room and battery room are all closely
associated with the workbays, and should be as
nearly adjacent to them as possible.
The shop office should overlook both the
workbays and the MEP for control and security
The flammable storage and controlled
waste storage rooms must open only to the exterior
of the building.

authorization must also accommodate separate
janitorial, electrical, telephone, and IT space
requirements. The mechanical equipment rooms
are best located off a corridor, and need not be
adjacent to the workbays. Where climate permits,
they could be accessible from the exterior of the
