safety of four on the ultimate strength of the tank material
used with a design head of not less than 4 feet of liquid
above the top of the tank.
4 Anodic to most common metals. Avoid dissimila-metal
contact with tank body unless galvanically compatible.

any horizontal dimension shall be
fitted with vertical baffle plates of the
same material as the tank. Limber
holes at the bottom and air holes at
the top of all baffles shall be provided.
Tanks constructed of material of greater thickness than minimum require-
