CORROSIVE LIQUIDS, FUME HAZARD GASES AND COMPRESSED GASES
(a) The provisions of Sections 385.46 to 385.51 shall govern the storage and handling of corrosive liquids and fume hazard gases. However, such provisions shall not apply, and no permit shall be required, for the storage or handling of such liquids or gases in small quantities in research laboratories, hospitals, chemical or educational laboratories, retail drug stores or similar establishments, except that such liquids and gases shall, wherever practicable, be kept in containers which conform to the requirements specified in Sections 385.46 to 385.51.
(c) Corrosive liquids shall include hydrochloric, nitric, sulphuric, perchloric, hydrofluoric and other similar acids; alkaline caustic liquids; and other corrosive liquids which react chemically with common materials such as wood or iron, or which may emit hazardous or irritant fumes, or generate heat and cause fire when in contact with organic matter or water, or cause severe damage when in contact with living tissue, or are otherwise similarly hazardous to life or property.
(d) Fume hazard gases include ammonia, chlorine, phosgene, sulphur-dioxide and other similar poisonous, irritant, corrosive or fume hazard gases.
(e) Except as provided in subsection (a) hereof, a permit from the Fire Chief shall be required for the storage or use of fume hazard gases, and for the storage of corrosive liquids in excess of one (1) carboy or an aggregate of five (5) gallons.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) Bulk storage of corrosive liquid out-doors shall be in above-ground tanks sufficiently isolated from adjacent premises so as not to endanger such adjacent premises.
(b) Except in buildings devoted primarily to the manufacturing or processing of corrosive liquid, storage of corrosive liquid within buildings shall be in carboys or containers constructed and protected as required by the Interstate Commerce Commission regulations. Storage in quantity shall be at the lowest floor of the building within a fire-resistive storage room equipped with adequate natural or mechanical ventilation and conforming to the applicable provisions of Section 3129.43(c).
(c) Buildings devoted primarily to the manufacture or processing of corrosive liquid shall be of Type I-A, I-B or I-C, fireproof construction, and the arrangement, location and protection of such buildings shall be subject to the approval of the Fire Chief. All storage tanks shall be installed within diked areas arranged to receive and retain the contents of the tanks in the event of rupture or leakage.
(d) Corrosive liquids shall be stored over safety catch basins or similar devices so that leakage of such liquids shall not endanger life or property. Corrosive liquids shall be stored so that unauthorized persons shall not have ready access thereto. None shall be stored in proximity to any substance in combination with which toxic vapors or gases will be produced.
(e) Containers of nitric acid or perchloric acid, or of other corrosive liquid which reacts dangerously in a similar manner, shall be stored only on brick, concrete or asphalt floors, or other approved acid-resistive floor or support. No sawdust, hay, excelsior or other organic substance, or other acids, chemicals, copper or brass, shall be stored in close proximity.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) The storage, handling and use of corrosive liquids shall be such as not to endanger life or property or to be hazardous in the event of fire or fire-fighting operations.
(b) Except in buildings devoted primarily to the manufacturing or processing of corrosive liquid, the quantity of corrosive liquid kept or maintained above the lowest floor level within one (1) room or fire area shall not exceed that required for one (1) day’s operations.
(c) A sufficient quantity of inert absorbent material suitable for the material stored shall be provided for absorbing all spilled liquids from floors where corrosive liquids are stored or used. Where corrosive liquids are of such nature that flushing with water is the proper procedure for clearing away spillage or leakage, first-aid hose or other approved adequate water supply shall be maintained in close proximity to the place of storage or usage.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) Ammonia may be stored in outside above- ground tanks in isolated locations where the fumes from such storage or resulting from leakage will not create a nuisance or endanger life.
(b) Except as provided in subsection (a) hereof, and except as otherwise specifically permitted under conditions deemed by the Fire Chief to provide adequate safety for life and property, all poisonous, irritant, corrosive or fume hazard gases shall be stored in cylinders conforming to the specifications of the Interstate Commerce Commission and bearing the ICC label of approval, and periodically retested as required by the ICC regulations. The storage of such cylinders shall be subject to the rules and regulations of the Division of Fire, and to their direction, so as to insure safety to life and property and prevent hazards in the event of fire or fire-fighting operations.
(c) Such ICC cylinders may be stored outdoors in enclosed lots or yards in sparsely settled sections at the discretion of the Chief and under such restrictions as he or she may deem necessary.
(d) When such ICC cylinders are stored within buildings, they shall be stored at the ground floor only, in a well-ventilated room or compartment conforming to the applicable provisions of Section 3129.43(c), readily accessible from the street or from an open space leading to a street, and equipped with an approved automatic sprinkler system and with provisions so that the room or compartment may be readily flooded with water from an outside controlled source. However, storage rooms or compartments for lighter-than-air gases, such as ammonia, may be in the top stories of buildings in locations from which such gases can readily diffuse into the atmosphere and as approved by the Chief.
(e) No poisonous, irritant, corrosive or fume hazard gas, except such gases permitted in refrigerating systems, shall be used above the ground floor of any building except in a building equipped with an automatic sprinkler system or other approved automatic fire extinguishing equipment and occupied exclusively by the person, firm or corporation using such gas.
(f) No poisonous, irritant, corrosive or fume hazard gas, except such gases permitted in refrigerating systems, shall be stored or used in any Class A or Class B multiple dwelling or dwelling house or in any building, lot or enclosure located within fifty (50) feet of the nearest wall of a building occupied so as to come under the occupancy classifications of Institutional Occupancy, Educational Occupancy or Assembly Occupancy. (Note exceptions under Section 385.46(a)).
(g) The Board of Building Standards and Building Appeals may by rule prescribe the maximum quantity of any fume hazard gas to be kept upon any premises or in connection with any occupancy and the manner of storage and use thereof.
