Class I flammable liquids, other than motor fuels, shall be dispensed from tank trucks into portable containers under the following conditions:
(a) The portable container and the tank truck shall be electrically interconnected and positively grounded during filling operations.
(b) The container used shall be an approved safety can or a metal drum.
(c) Smoking shall not be allowed during filling operations. No other ignition sources shall be within 20 feet unless necessary for the transfer of the flammable liquid.
(d) Actual filling operations shall be conducted outside the building. Safety clearances of ten feet shall be maintained between the filling operations and any structure. Provided, however, filling operations may be conducted inside a building or room designed for flammable liquid use, if a fixed piping system is used from the truck located outside the building and entering directly into the building or room designed for flammable liquid use.
(Prior code § 129.1-28)
The walls, floor and ceilings of a standard fireproof vault, whenever such a room is required by this Code, shall be built of reinforced concrete or masonry of not less than two-hour fire-resistive construction. The distance from the floor to the ceiling of a standard fireproof vault shall not exceed 11 feet. Where a standard fireproof vault is located within any building, the cubical contents of such standard fireproof vault shall not exceed 750 cubic feet. Where a standard fireproof vault is located outside of a building so that a safety clearance of not less than five feet is provided on not less than three sides of such fireproof vault, the cubical contents of such vault shall not exceed 1,500 cubic feet. Nothing in this chapter shall be construed as prohibiting more than one standard fireproof vault in any building or structure or on any lot or plot of ground. All openings in the floors, walls, or ceilings of standard fireproof vault, except required vent flue openings and window openings for ventilation, shall be equipped and protected with a Class A fire door of the automatic type and shall have as its actuating mechanism to close such door, a thermostatic releasing device. No wood floor, wood racks, wood shelves, or any other combustible material other than the substance for which any standard fireproof vault is intended shall be allowed or permitted in such vault. Shelves or racks used to support the material stored in vault shall be of metal and of open construction, so arranged as to permit water from the sprinkler heads to pass between container or packages.
Flammable Liquids. Whenever a standard fireproof vault is used for the storage of flammable liquids, there shall be a sill at every doorway thereto, constructed of noncombustible materials and six inches high above the level of the floor of the vault. All floor drains in a vault used for storing or keeping flammable or corrosive liquids shall have no connections with the drainage system of the building, but shall be arranged to drain to a location outside of the building remote from all connections or drains to the sewer system.
(Prior code § 129.1-29)
For automatic sprinkler requirements, see Chapter 15-16 of this Code.
(Prior code § 129.1-30)
Any lighting in a standard fireproof vault shall be by electricity only. The light shall be controlled by an indicating switch located on the outside of the vault. All such lights shall be equipped with wire guards, keyless sockets, and vaporproof globes.
(Prior code § 129.1-31)
Every standard fireproof vault shall have a vent flue or window opening directly to the outer air. Such vent flue termination or window shall be located not less than ten feet measured vertically or five feet measured horizontally from any fire door or fire window, or not less than 20 feet measured vertically, or ten feet measured horizontally, from any unprotected opening. Such window or vent flue shall have a net open area of not less than five percent of the total wall area in the standard fireproof vault. Nothing in this chapter shall be construed as prohibiting on each floor, vent shaft connections from standard fireproof vaults into one vent shaft; provided, however, that not more than four such vaults on any one floor shall be connected to one such vent shaft. The area of the combined vent shaft shall be of such area as is required to vent the largest of the standard vaults for which said vent shaft provides ventilation. All vent flues or portions of vent flues shall have no inclination from the horizontal of less than 45 degrees. Nothing herein shall be construed as preventing more than one window or vent flue or combination of windows or vent flues to provide the necessary ventilating area. Any such vent flue shall be used for no other purpose than to provide ventilation from standard fireproof vaults. Such vent flue shall be constructed of brick, tile or concrete walls not less than four inches in thickness, and no combustible material shall be used in the construction or support of flues. Any vent flue opening in a standard fireproof vault shall be in the ceiling or as close as practicable to the ceiling. The unobstructed opening into the atmosphere shall be not less in area than the area of the vent flues. Every vent flue furnishing the required ventilation shall be equipped with not less than a 60-minute fire-resistive door which shall be held normally closed, and such fire door shall have as its actuating mechanism a thermostatic releasing device to open the door. Such a door in the vent flue shall be so arranged that when the door is opened, the entire required area of the vent flue shall be available for ventilation purposes. All required windows shall be so provided with thermostatic releasing devices that a fire or an explosion in the vault shall cause such windows to open for the entire required ventilation area.
(Prior code § 129.1-32)
In any special room for flammable liquids, the door openings to other rooms or buildings shall be provided with noncombustible sills, raised not less than six inches above the floor or such special room. Where the total quantity of Class I liquids stored or handled in any room, does not exceed 200 gallons, such room shall have floors, walls and ceilings of not less than one-hour fire-resistive construction. Floors shall be arranged to drain toward the outside of the building. Where the total quantity of Class I flammable liquids stored or handled in any rooms exceeds 200 gallons, but does not exceed 400 gallons, all floors, walls and ceilings of such room shall be of not less than two-hour fire-resistive construction. Where the total quantity of Class I flammable liquids stored or used exceeds 400 gallons, but does not exceed 600 gallons, the floors, walls and ceilings of such room shall be of not less than three- hour fire-resistive construction. Where the total quantity of Class I flammable liquids stored or used exceeds 600 gallons, the floors, walls and ceilings of such room shall be of not less than four-hour fire-resistive construction.
Outside storage houses for the storage and handling of flammable liquids shall be constructed in accordance with this section. All door openings through the enclosures of such rooms into other rooms or buildings, shall have fire doors as required by Chapter 15-12 of this Code for such fire-resistive walls. The provisions of this paragraph do not apply to fuel oil storage tanks otherwise permitted by Section 15-24-270. Ventilation as required by Section 15-24-400 shall be provided.
(Prior code § 129.1-33)
Unless otherwise specified in the building provisions of this Code, oils, paints, varnishes and similar fluids having a flashpoint above 200 degrees Fahrenheit, according to the standard tests for flashpoint, shall, if stored in any building used for other purposes, in quantities exceeding ten barrels aggregate, be placed in approved metal tanks, and shall be drawn only by the use of approved pumps or other approved devices. Quantities less than ten barrels aggregate may be stored in barrels, or ordinary tanks, and if drawn on the premises, suitable drip pans shall be provided to catch the drips. Boxes of sawdust shall not be used for the purpose. The premises surrounding such tanks shall be kept clean at all times. Any absorbents used to clean flammable liquid spills shall be approved by a nationally recognized testing laboratory.
