[Amended 3-16-2010 by L.L. No. 1-2010]
This article shall apply to materials not otherwise covered in this chapter which are highly flammable or which may react to cause fires or explosions, or which by their presence create or augment a fire or explosion hazard, or which because of their toxicity, flammability or liability to explosion render firefighting abnormally dangerous or difficult; also to flammable liquids which are chemically unstable and which may spontaneously form explosive compounds or undergo spontaneous reactions of explosive violence or with sufficient evolution of heat to be a fire hazard. Hazardous chemicals shall include such materials as flammable solids, corrosive liquids, radioactive materials, oxidizing materials, potentially explosive chemicals, highly toxic materials and poisonous gases, as defined in § 143-39 of this article.
[Amended 3-16-2010 by L.L. No. 1-2010]
For the purpose of this article, the terms used herein are defined as follows:
CORROSIVE LIQUID
Those acids, alkaline caustic liquids and other corrosive liquids which, when in contact with living tissue, will cause severe damage of such tissue by chemical action, or, in case of leakage, will materially damage or destroy other containers of other hazardous commodities by chemical action and cause the release of their contents, or are liable to cause fire when in contact with organic matter or with certain chemicals.
FLAMMABLE SOLID
A solid substance, other than one classified as an explosive, which is liable to cause fires through friction, through absorption of moisture, through spontaneous chemical change or as a result of retained heat from manufacturing or processing.
HIGHLY TOXIC MATERIAL
A material so toxic to man as to afford an unusual hazard to life and health during fire-fighting operations. Examples are parathion, TEPP (tetraethyl phosphate), HETP (hexaethyl tetraphosphate) and similar insecticides and pesticides.
OXIDIZING MATERIAL
Substances, such as chlorates, permanganates, peroxides or nitrates, that yield oxygen readily to stimulate combustion.
POISONOUS GAS
Any noxious gas of such nature that a small amount of the gas, when mixed with air, is dangerous to life. Examples are chloropicrin, cyanogen, hydrogen cyanide, nitrogen peroxide and phosgene.
POTENTIALLY EXPLOSIVE CHEMICAL
Any chemical substance, other than one classified as an explosive or blasting agent, which has a tendency to be unstable and which can be exploded by heat or stock or a combination thereof.
RADIOACTIVE MATERIAL
Any material or combination of materials that spontaneously emits ionizing radiation.
SEALED SOURCE
A quantity of radiation so enclosed as to prevent the escape of any radioactive material but at the same time permitting radiation to come out for use.
[Amended 1-23-1996 by L.L. No. 1-1996; 3-16-2010 by L.L. No. 1-2010]
A certificate of compliance shall be required for the storage or handling of corrosive liquids, oxidizing materials, organic peroxides, nitromethane, ammonium nitrate, ammonium nitrate fertilizers, fertilizer mixtures, highly toxic material, poisonous gas or radioactive material.
[Amended 12-31-1996 by L.L. No. 18-1996; 3-16-2010 by L.L. No. 1-2010]
A. 
The manufacture, storage, handling and use of hazardous chemicals shall be safeguarded with such protective facilities as public safety requires.
B. 
The Chief Fire Safety Inspector may require the separation or isolation of any chemical that in combination with other substances may bring about a fire or explosion or may liberate a flammable or poisonous gas. The Chief Fire Safety Inspector may require separation from other storage, occupancies or buildings when the quantity stored constitutes a material hazard.
C. 
Where identification of buildings and structures containing hazardous materials is required in accordance with the New York State Uniform Fire Prevention and Building Code,[1] the National Fire Protection Association Hazardous Materials Identification System (NFPA 704) shall be utilized.
[1]
Editor's Note: See Executive Law § 370 et seq.
Packaged oxidizing materials shall be stored in dry locations and separated from stored organic materials. Bulk oxidizing materials shall not be stored on or against wooden surfaces.
A. 
Durable, clearly visible signs warning of radiation dangers shall be placed at all entrances to areas or rooms where radioactive materials are used or stored. In addition, each container in which radioactive materials are used, stored or transported shall bear a durable, clearly visible, appropriate warning sign. Such signs shall bear the three-bladed radiation symbol in magenta or purple on a yellow background in accordance with nationally recognized good practice.
B. 
When not in use, radioactive materials shall be kept in adequately shielded fire-resistant containers of such design that the gamma radiation will not exceed 200 milliroentgens per hour or equivalent at any point of readily accessible surface.[1]

Former § 143-56, Potentially explosive chemicals, § 143-57, Highly toxic materials, § 143-58, Poisonous gases, and § 143-59, Corrosive liquids, were repealed 3-16-2010 by L.L. No. 1-2010. This local law also redesignated former § 143-60 through § 143-66 as § 143-44 through § 143-50, respectively.
