The facilities should be inspected at least yearly to determine the need for maintenance. The Maintenance/Facilities Self-Assessment checklist provides guidance to assess the need for maintenance and repair of the facilities. The
location should check all structure, system, and equipment warranties
and make sure that the warranty expiration dates are calendared and
incorporated into the plan. Equipment and system warranties usually
require maintenance by factory-authorized representatives. Maintenance
by unauthorized personnel often voids warranties.
