4.10 Structural Inspection
Visual inspection should be done annually to check paint and look for possible
corrosion, especially at footings, structural tie points, and ground rods. Fasteners
should be checked, tightened, or replaced as required.
At least once a year, check the inside of the display for signs of water intrusion, i.e.
-
water stain marks. Water can enter a display where weather stripping has come loose
or deteriorated, where fasteners have come loose allowing gaps in the panels, or
where moisture may be entering around hardware. Check the electronic components
for signs of corrosion.
Check/clean the filters for proper air flow.
