JUMP TO FULL CODE CHAPTER
(a) Scope. This section sets forth standards, requirements and procedures for mobile trailers that store and use fuel oil for heating and generation of electrical power.
(b) General Provisions.
(1) Applicability. Mobile trailers that store and use fuel oil for heating, including steam and hot water, and generation of electrical power, shall be designed, installed and operated in compliance with the requirements of the construction codes and this section.
(2) Permit. Each mobile heating or power generating trailer shall obtain a permit for the citywide transportation, storage and use of combustible liquid. Mobile heating and power generating trailers utilized at one (1) site for more than 30 days shall obtain a site-specific permit for the storage and use of combustible liquid at that location.
(3) Supervision. While in operation, mobile emergency heating and power generating trailers shall be under the personal supervision of a certificate of fitness holder or a person holding a high pressure boiler operating engineer's license issued by the Department of Buildings.
(4) Delivery of fuel oil. Only cargo tanks for which a permit has been issued may be used to deliver fuel oil to mobile heating and power generating trailers.
(c) Design and Installation Requirements. Mobile heating and power generating trailers using fuel oil shall be designed and installed in compliance with the following requirements:
(1) Fuel oil piping systems and boilers shall be designed and installed in compliance with the requirements of the Mechanical Code. The power generating equipment, and all electrical devices, equipment and systems on the trailer shall be designed and installed in compliance with the requirements of the Building Code and the Electrical Code. Documentation of compliance with such codes shall be submitted to the Department in an approved form.
(2) Fuel oil storage tanks shall be constructed in accordance with the requirements of the Mechanical Code. No more than 550 gallons of fuel oil shall be stored on the trailer.
(3) A clearly identified and readily accessible remote control shut-down switch for the oil burning equipment shall be provided inside the trailer, immediately accessible upon entry.
(4) The chassis shall be designed and constructed to support the total load supported by the trailer, including all heating or power generating equipment. The Department may require a letter from the chassis manufacturer confirming such design capacity.
(5) Fuel oil storage tanks shall be provided with secondary containment of liquid- tight construction. Such containment shall be constructed of metal, and shall have a capacity of not less than the maximum capacity of the fuel oil storage tanks.
(6) Signs shall be posted on both sides of the trailer that read: "Mobile Heating Trailer" or "Mobile Power Generator", as applicable, in six (6) inch letters, and bear the name and address of the owner in two (2) inch letters.
(7) The trailer and equipment shall be electrically grounded in an approved manner.
(8) Each fuel oil storage tank fill line shall be provided with both a shut-off valve and a check valve.
