This Article shall apply to the storage, handling
and use of flammable liquids as hereinafter defined, except that it
shall not apply to the transportation of flammable liquids when in
conformity with Interstate Commerce Commission regulations or regulations
lawfully on file with and approved by the Interstate Commerce Commission.
As used in this Article, the following words,
terms and phrases shall have the meanings herein ascribed to them:
A container so sealed by means of a lid or other device that
neither liquid nor vapor will escape from it at ordinary temperatures.
Any liquid having a flash point below 200º F. and having
a vapor pressure not exceeding 40 pounds per square inch (absolute)
at 100º F. "Flammable liquids" shall be divided into three classes,
as follows:
The minimum temperature, in degrees Fahrenheit, at which
a flammable liquid will give off flammable vapor as determined by
appropriate test procedure and apparatus as specified below:
The flash point of flammable liquids having
a flash point below 175º F. shall be determined in accordance
with nationally recognized good practice using the tag closed tester.
The flash point of flammable liquids having
a flash point of 175º F. or higher shall be determined in accordance
with nationally recognized good practice using the Pensky-Martens
closed tester.
A permit shall be obtained for any of the following:
A.
The storage, handling or use of Class I or Class II
flammable liquids in excess of one gallon in dwellings or other places
of human habitation; or in excess of six gallons in any other place
of occupancy; or in excess of 10 gallons outside of any building;
except that no permit shall be required for the following:
(1)
For the storage or use of flammable liquids for the
fuel tank of a motor vehicle, aircraft, motorboat, mobile power plant
or mobile heating plant.
(2)
For the storage or use of paints, oils, varnishes
or similar flammable mixtures when such liquids are stored for maintenance,
painting or similar purposes for a period of not more than 30 days.
B.
The storage, handling or use of Class III flammable
liquids in excess of 25 gallons in a building or in excess of 60 gallons
outside of a building.
C.
For the manufacture, processing, blending or refining
of flammable liquids.
D.
For the storage of flammable liquids in stationary
tanks.
A.
Design and construction. Class I and Class II flammable
liquids shall be transferred from underground tanks by means of fixed
pumps so designed and equipped as to allow control of the flow and
to prevent leakage or accidental discharge. Supplemental means shall
be provided outside of the dispensing device whereby the source of
power may be readily disconnected in the event of fire or other accident.
Dispensing devices for Class I or Class II flammable liquids shall
be of approved type. Class I or Class II flammable liquids shall not
be dispensed by pressure or gravity from drums, barrels and similar
containers. Gear pumps or similar positive displacement devices taking
suction through the top of the container shall be used. Class I and
Class II flammable liquids shall not be dispensed by a device that
operates through pressure within a storage tank, unless the tank has
been approved as a pressure vessel for the use to which it is subjected.
In no case shall air or gas pressure be used for this purpose.
B.
Automatic dispensing devices.
(1)
The dispensing of Class I and Class II flammable liquids
into the fuel tank of a vehicle or into a container shall at all times
be under the supervision, observation and control of at least one
attendant on duty while the station is open to the public. The use
of any device which permits the dispensing of Class I and Class II
flammable liquids when the hand of the operator of the discharging
nozzle is removed from the nozzle control lever is hereby forbidden
except when using an automatic nozzle as provided in this code.
(2)
Automatic hose nozzle valves with latch-open devices.
In lieu of being held open by hand, an approved automatic nozzle may
be used for dispensing Class I and Class II flammable liquids into
the fuel tank of a vehicle. Such a nozzle shall have the latch-open
device as an integral part of the assembly and shall shut off the
liquid reliably and positively when the gasoline tank is filled, when
it falls from the filling neck of an automobile tank, when it is subject
to rough usage such as dropping or lack of proper lubrication or when
an automobile is driven away while the nozzle is still in the tank.
At a self-service station, hose nozzle valves shall be automatic closing
types without a latch-open device. An attendant shall be in the immediate
vicinity of the vehicle being filled by such an approved nozzle. The
"immediate vicinity" shall mean within an authorized booth where the
control sources of ignition or the on-off operation of the pumps including
an emergency cutoff by remote control by means of a console in the
booth.
C.
Location. Dispensing devices at service stations shall
be so located that all parts of the vehicle being served will be on
private property.
In rooms or areas accessible to the public,
storage of flammable liquids shall be in stored containers and limited
to quantities needed for display and normal merchandising purposes.
Where the aggregate quantity of additional stock exceeds 50 gallons,
it shall be stored in rooms or portions of buildings that comply with
the following construction requirements:
A.
Walls, floors and ceilings shall be of construction
having a fire-resistance rating of not less than two hours. Openings
to other rooms or buildings shall be provided with noncombustible
liquidtight raised sills or ramps at least six inches in height and
with approved fire doors with heat-actuated releasing devices arranged
to close doors automatically in case of fire. Where other portions
of the building or other properties are exposed, windows shall be
of wire glass and protected in an approved manner. No combustible
material shall be used for interior room surfaces or shelving. Proper
ventilation shall be provided. Heating shall be restricted to low-pressure
steam or hot water. All electrical switches shall be located outside
the boiler room and all fixtures shall be equipped with bulb protectors
and explosionproof bulbs.
