Protection From Damage
1. All storage tanks installed in areas where they may be subjected
to mechanical damage shall be suitably guarded against such
damage by being installed behind adequate barriers or by being
elevated or located out of the normal path of a vehicle using any
such garage.
2. In seismic zones 3 and 4, storage tanks shall be anchored or
strapped to resist horizontal displacement due to earthquake
motion. Strapping shall be at points within the upper one-third
(1/3) and lower one-third (1/3) of its vertical dimensions. At the
lower point, a minimum distance of four (4) inches (102 mm) shall
be maintained above the controls with the strapping.
3. A storage tank supported from the ground shall rest on level
concrete or other approved base extending not less than three (3)
inches (76 mm) above the adjoining ground level.
4. When a storage tank is located in an attic, attic-ceiling assembly,
floor-ceiling assembly, or floor-subfloor assembly where damage
may result from a leaking storage tank, a watertight pan of
corrosion resistant materials shall be installed beneath the storage
tank with a minimum three-quarter (3/4) inch (20 mm) diameter
drain to an approved location.
