Discharge devices shall be of a type that do not develop an internal pressure on the container. Pumping devices or approved self-closing faucets used for dispensing liquids shall not leak and shall be well-maintained. Individual containers shall not be interconnected and shall be kept closed when not in use.
The capacity of a storage tank temporarily installed aboveground containing flammable or combustible liquids shall not exceed 660 gallons (2498 L). Tanks shall be of the single-compartment design, shall be constructed of steel, and shall meet the requirements of the New York State Department of Environmental Conservation regulations, as set forth in 6 NYCRR Parts 613 and 614.
Fill openings shall be equipped with a locking closure device. Fill openings shall be separate from vent openings.
Tanks shall be provided with a method of normal and emergency venting. Normal vents shall also be in accordance with FC3404.2.7.3. Emergency vents shall be in accordance with FC3404.2.7.4. Emergency vents shall be arranged to discharge in a manner which prevents localized overheating or flame impingement on any part of the tank in the event that vapors from such vents are ignited.
Tanks containing flammable or combustible liquids shall be kept outdoors and at least 50 feet (15 240 mm) from buildings, combustible material and combustible waste. Additional distance shall be provided when necessary to ensure that vehicles, equipment and containers being filled directly from such tanks will not be less than 50 feet (15 240 mm) from structures or combustible storage.
Tanks with top openings shall be mounted as follows:
- On well-constructed metal legs connected to shoes or runners designed so that the tank is stabilized and the entire tank and its supports can be moved as a unit; or
- For stationary tanks, on a stable base of timbers or blocks approximately 6 inches (152 mm) in height which prevents the tank from contacting the ground.
Tanks with top openings only shall be equipped with a tightly and permanently attached, approved pumping device having an approved hose of sufficient length for filling construction equipment or containers to be served from the tank. Either the pump or the hose shall be equipped with a padlock to its hanger to prevent tampering. An antisiphoning device shall be provided in the pump discharge unless a self-closing nozzle is used. Siphons or internal pressure discharge devices shall not be used.
Tanks with a connection in the bottom or the end for gravity-dispensing liquids for aerial crane refueling operations shall be mounted and equipped as follows:
- Support lugs used to elevate the tank for gravity discharge shall be designed to carry all required loads and provide stability.
- Bottom or end openings for gravity discharge shall be equipped with a valve located adjacent to the tank shell which will close automatically in the event of fire through the operation of a heat-activated releasing device. Where this valve cannot be operated manually, it shall be supplemented by a second, manually operated valve.
- The gravity discharge outlet shall be provided with an approved hose equipped with a self-closing valve at the discharge end of a type that can be padlocked to its hanger.
Where approved, liquids used as fuels are allowed to be transferred from cargo tanks into the fuel tanks of construction equipment at a construction site, subject to the following requirements:
- The cargo tank is used solely for the purpose of supplying fuel to construction equipment at a construction site.
- The dispensing hose does not exceed 100 feet (30 480 mm) in length.
- The dispensing nozzle is an approved type.
- The dispensing hose is properly placed on the approved reel or in a compartment provided before the cargo tank is moved.
- Signs prohibiting smoking and open flames within 25 feet (7620 mm) of the cargo tank and construction equipment being refueled are prominently posted on the cargo tank.
- Electrical devices and wiring in areas where fuel dispensing is conducted are in accordance with the Electrical Code.
- Cargo tank-dispensing equipment is operated only by a person holding a certificate of fitness.
- Provision has been made to control and mitigate the accidental or unauthorized release of flammable and combustible liquid.
- The cargo tank has a capacity of not more than 1,920 gallons (7267 L), and contains no Class IA liquid and not more than 640 gallons (2422 L) of any other Class I liquid.
- Dispensing is conducted at least 50 feet (15 240 mm) from buildings, structures, combustible material or combustible waste.
- A portable fire extinguisher with a minimum rating of 40-B:C shall be provided on the cargo tank with signage clearly indicating its location.
- Absorbent materials, nonwater-absorbent pads, a 10-foot-long (3048 mm) containment boom, an approved container with lid and a nonmetallic shovel shall be provided to mitigate a minimum 5-gallon (19 L) fuel spill.
- Operators of tank vehicles used for mobile fueling operations shall have in their possession at all times an approved means of notifying the department of a fire or other emergency.
- Fuel dispensing shall be prohibited within 25 feet (7620 mm) of any source of ignition.
- The engines of vehicles being fueled shall be shut off during dispensing operations.
- Nighttime fueling operations shall only be conducted in adequately lighted areas.
- The cargo tank shall be positioned with respect to the construction equipment being fueled so as to prevent vehicular traffic from driving over the delivery hose.
- During fueling operations, a cargo tank shall be secured from movement by setting the cargo tank's brakes and chocking the wheels, and the cargo tank's warning lights shall be activated.
