Vehicles delivering or picking up hazardous materials to or from commercial and industrial complexes may travel the nearest and most direct public roadway to said complex. 2. Vehicles containing hazardous materials that are operated by local businesses, may travel the nearest and most direct public roadway to said place of business. (c) Vehicle parking - Except in an emergency, no vehicle trans- porting hazardous materials shall be left unattended on any street, highway, alley or parking lot, provided that this shall not prevent the driver or operator from the necessary absence from said vehicle in connection with the delivery or pick up of the load, except that during actual discharge of said hazardous materials, some responsible person shall be present at said vehicle; nor shall it prevent stops for meals during the day or night, provided that said vehicle be parked in a safe manner; nor shall it prevent said vehicle from being parked for any reason at an area approved by the fire marshal. Sec. 10-103. Handling of emergency conditions; fire protection and prevention measures generally. (a) Provisions shall be made in all storage areas .for hazardous materials, for the proper handling of emergency conditions such as leaks, spills and ruptures. Employees shall be instructed on proper procedures for notifying emergency services, appropriate emergency action, if any; and appropriate evacuation procedures. (b) Where open flame constitutes a hazard, the fire marshal may restrict smoking and require posting of "NO SMOKING" signs. (c) Portable fire extinguishers shall be provided in accordance with special care to any reactivity between chemicals stored and extinguisher agent selected. 9 (d) Large fire suppression systems or devices may be required where determined by the fire marshal. (e) A conspicuous placard shall be permanently displayed begin- ning with the words, "In Case of Fire"; such placard shall designate the fire department phone number and such other safety precautions the fire marshal deems necessary. (f) Means shall be available for calling the fire department.

Sec. 10-104. Disposition of hazardous materials incidents. (a) No hazardous materials of any type shall be disposed of by any means unless approved by the fire marshal. (b) Hazardous materials incidents, (spills, leaks, etc.) shall be cleaned up in an approved manner, beginning immediately upon re- lease of the scene by the fire marshal. The following principals shall be responsible for said clean-up. 1. By the carrier or his designee, if on a public roadway or parking area normally accessible to the public; 2. By the owner or tenant (as determined by the fire marshal) of private properties where hazardous materials incidents occur. This shall include fixed properties (buildings, slabs, etc.) that may be damaged as the result of said incident. 3. All clean-up costs, reimbursements, etc. shall be the com- plete responsibility of the carrier, owner(s), tenant(s), etc. as determined by the fire marshal or investigating official. Local authorities shall have the right to engage environmental disposal contractors for clean-up, if necessary. Sec. 10-105. Hazardous materials. The storage and transportation of flammable and combustible liquids, liquefied petroleum gas, explosives, fireworks, and other hazardous materials shall be as specified in this code. Sec. 10-106. Penalty. Any person, firm or corporation who shall violate or fail to comply with the requirements of any provision of this article, shall be guilty of a misdemeanor and shall, upon conviction by a court of competent jurisdiction, be punished as provided in Section 1-11 of the City Code of Ordinances. 10 These substances react strongly with water, steam or water solu- tions to produce heat and flammable or explosive rials, such as the alkali metals and metal hydrides, Some undergotea vigorous exothermic reaction with water, evolving hydrogen, which may be ignited spontaneously by the heat of reaction. The alkali metals also react strongly with all common extinguishing agents. The acid anhydrides, concentrated acids, and alkalies will react to produce considerable heat. Other compounds react with water or decompose when heated to produce flammable gases or explosive hydrides. In many cases, these gases are extremely toxic. The vola- tile hydrides, including those of boron, phosphorous, and arsenic, will ignite spontaneously in air. (1) Materials that are hazardous in contact with water shall be stored and handled in buildings of fire -resistive or damage limiting construction, safely protected from floods and windstorm damage. (2) Complete sprinkler protection shall be provided if ordinary combustibles are present or if construction is combustible. Sprinkler water does not increase the hazard of an explosion because flammable gases released by reaction with water would ignite immediately. The sprinkler discharge would protect the building, prevent ignition beyond the immediate burning zone, and ultimately extinguish or control the fire. (4) Buildings having these materials shall be dry, cool and well ventilated. They may be heated indirectly by dry hot air systems. Avoid the use of steam heating systems. Buildings shall be designed as for hydrogen storage, with approved powered roof vents to remove light gases promptly. (5) Automatic detection and alarm systems to warn of dangerous accumulations of flammable gases may be required by the fire marshal where sufficient hazards exist. (6) The materials shall usually be stored in airtight sealed containers and handled in dry boxes containing an inert gas atmosphere. Sec. 10-101. Construction of cabinets for storage of hazardous mate- rials. Cabinets for the storage of hazardous materials shall be approved and substantially constructed of No. 16 gauge sheet iron or a minimum of one -inch plywood or equivalent. Doors shall be painted with an intumescent type paint and shall be conspicuously labeled in red letters "Hazardous --Keep Fire Away." All facilities to be marked with the symbols required in N.F.P.A. Standard No. 704m. Where more than one (1) hazardous chemical is stored in a given cabinet, then list the most dangerous first, followed by the remaining chemicals. 8
