Section 5404 of the CFC is hereby adopted in its entirety with the following exceptions, modifications, and additions.

SEC. 57.5404.3. DRUM AND CARBOY STORAGE.¶

The storage of corrosive materials in drums or carboys shall conform to the following:

Drums or carboys shall not be stacked more than two containers high unless on pallets. Maximum height shall be 12 feet.
Unless otherwise specifically authorized by the Chief, drum or carboys shall be stored in rows not more than two containers in width, or the width of the pallet, if stored on pallets. The aisles between such

rows shall be of sufficient width to permit inspection and removal of leaking drums or carboys.

Drums and carboys shall be stored in an upright position with a bung or plug uppermost.
Excess pressure which may have developed from high temperature hydrogen formation in drums or carboys equipped with non-porous or non-venting stoppers, plugs, or caps, shall be vented when containers

are placed in storage. Drums shall be opened at frequent intervals to prevent excessive pressure developing from hydrogen formation.

Tanks used for the storage of corrosive materials shall comply with the following provisions:

Tanks shall be equipped with manual shut- off valves which may be operated without going beneath the tank.
Tanks having a capacity in excess of 120 gallons and located within or upon buildings shall be equipped with heat-actuated, automatic-closing shutoff valves approved by the Chief.

EXCEPTION:

The Chief may permit the use of a remote-control valve which is clearly labeled and located where easily accessible in the event of fire or another emergency.
Tanks not resting upon the ground or floor and located within a building or within 10 feet of a combustible structure, shall rest on supports of at least one-hour fire-resistive construction.
When tanks are located outside of a building and are connected to piping entering a building, conspicuously labeled emergency shutoff valves shall be installed at a readily available place outside of the building.
