AN ORDINANCE OF THE CITY OF SARATOGA
AMENDING THE 1988 EDITION OF THE UNIFORM
FIRE CODE BY ADDING ARTICLE 88
CONCERNING TOXIC GASES
The City Council of the City of Saratoga hereby ordains as follows:
SECTION h The City Council finds and determines that:
(a) Article 80 of the 1988 Uniform Fire Code contains provisions for the
regulation of hazardous materials~ including regulation of compressed gases, but said
Article does not regulate other types of gases.
(b) The 1987-88 Santa Clara County Grand Jury found that the use of toxic
gases in industry posed a threat to the health and safety of local residents, and
recommended that the Intergovernmental Council ("IGC") develop an' ordinance
acceptable to industry, citizen groups, and local government. In response to this
recommendation, the IGC developed a model ordinance which could be used as part
of and a complement to, the 1988 edition of the Uniform Fire Code, and which is
proposed to be adopted by the governing bodies of all cities within Santa Clara
County, and by the County Board of Supervisors.
(c) It is appropriate to adopt the model ordinance in order to provide for a
uniform county-wide program for the prevention, control, and mitigation of
dangerous conditions, to provide for building standards and for emergency response
to protect the public from acute exposure due to accidental releases of toxic gases.
SECTION 2: Section 16-20.270 is added to Article 16-20 of the City Code, to
read as follows:
"S16-20.270 Article 88 added concerning toxic gases
Article 88 is hereby added to the Fire Code, to read as follows:

in conjunction with, other sections of this Code and with the
Uniform Building Code, 1988 edition.
(c) In the event of conflicting or overlapping regulatory
provisions within the Saratoga City Code, the Fire Code and
this Article, the more stringent requirement shall prevail.
(d) In the event of conflicting or overlapping regulatory
provisions with a federal law or state law or regulation,
unless the application of this Article is expressly preempted
by an Act of Congress or enactment of the state legislature,
the more stringent requirement shall be deemed to apply.
Definitions
See. 88.102 (a) Unless the context otherwise requires, the
words and phrases in this Article shall have the meanings set
forth in this Section and shall govern the construction of this
Article. For words and phrases not defined in this Section,
the definitions set forth in other articles of the Fire Code
shall control.
(b) For the purpose of this Article, certain terms and words
are defined as follows:
(1) Controls are a means to regulate materials so as
to prevent unauthorized discharges.
(2) Control Area means a space within a building
where regulated materials may be stored, handled,
dispensed or used. A control area is an area formed by
one or more of the following:
(A) An occupancy separation with a minimum
one-hoar fire resistive rating, or
(B) The exterior wall~ roof or foundation of the
building.
A maximum of four control areas shall be permitted
within a building except buildings or portions of
buildings used for retail sales, which shall have a
maximum of two control areas.
(3) Equilibrium Vapor Concentration ("EVC") means
the state of a regulated material at which vapor
pressure has stabilized and is no longer rising or falling.
EVC value of a regulated material is determined by
multiplying vapor pressare ('WP") by 106, and dividing
by atmospheric pressure; as shown in the following
equation:
Rev. 5/15/90 -2-
EVC (ppm) = Vapor Pressure x 106
Atmospheric Pressure [760 mmH~
Note: Vapor pressure for materials with a boiling point
equal to or less than 25°C shall be 760 mm Hg;
materials with a boiling point greater than 25°C shall
use the actual vapor pressure for that material at 25° C.
Atmospheric pressure is assumed to be 760 mm at sea
level.
(4) Facility means any building, structure,
installation, equipment, pipe, container, site, area,
appurtenant structure, or surrounding land area where
regulated materials are stored, used, dispensed,
handled, placed or otherwise have come to be located.

state at normal temperature and pressure.
(7) IDLH (Immediately dangerous to life or health)
means a concentration of airborne contaminants,
normally expressed in parts per million (ppm) or
milligrams per cubic meter, which represents the
maximum level from which one could escape within 30
minutes without any escape-impairing symptoms or
irreversible health effects. This level is established by
the National Institute of Occupational Safety and
Health (NIOSH). If adequate data do not exist for
precise establishment of IDHL data, an independent
certified industrial hygienist, industrial toxicologist or
appropriate regulatory agency shall make such
determination.
(8) Inert Construction MateriaLs means materials
which under reasonably foreseeable conditions will not
degrade or react upon contact with the regulated

concentration of a substance in air that will not cause
serious health effects in the majority of the population
when exposed to the substance for a relatively short
period of time. For purposes of this Article, the LOC is
equal to 0.I of the IDLH value if the particular
substance has an established IDLH, or if not, an
estimated LOC value based on acute toxicity values of
0.01 LCS0, 0.1 LCLo, 0.001 LDS0, or 0.01 LDLo.
(10) Lethal Coneenil'ation ("LCS0.) means the median
lethal concentration level, at which 50 percent of
Rev. 5/15/90 -3-
appropriate test animals die when exposed by inhalation

(13) Lethal Dose Low ("LDLo") means the lowest dose
of a chemical at which some test animals died following
exposure.
(14) Material Hazard Index ("MHI") means a numeric
value used for ranking of chemical substances
(materials) in order to determine the level of controls
necessary for regulated materials. MHI is determined
by dividing the EVC of a material at 25°C by the LOC
for the material, as shown in the following equation:
MHI = EVC (ppm) at 25°C
LOC (ppm)
(15) Ms~mum Threshold Quantity ("Max. T.Q.") means
the maximum quantity of a Class H or Class HI
regulated material which may be stored in a single
vessel before a stricter category of regulation is
required by this Article. Max. T.Q. is determined by
the following equation:
Max. T.Q.(lbs) = 2.5 x 108
MHI
(16) Minimum Threshold Quantity ("Min. T.Q.") means
the aggregate quantity of regulated materials in a
control area which, due to the minimal aggregate
quantities present, need only comply with specific
control requirements established in Subsection 88.40 l(e)
of this Article, and not with the requirements for Class

specified in this Subsection (e) and in Subsection (f) of this
Section.
(1) Exhaust Ventilation.
(A) Storage of cylinders shall be within
ventilated gas cabinets, exhausted enclosures, or
within a ventilated separate gas storage room as
defined in the Fire Code.
(B) Storage of portable and stationary tanks
shah be within a separate ventilated room without
other occupancy or use.
(C) If gas cabinets are provided~ the rpom or
area in which they are located shah have
independent exhaust ventilation.
(D) Exhaust systems for gas cabinets, exhausted
enclosures and separate gas storage rooms shall
be designed to handle the accidental release of
gas. Such exhaust systems shall be capable of
diluting, adsorbing, absorbing, neutralizing,
burning or otherwise processing the entire
contents of the single tank or cylinder of gas
which presents the higher potential hazard.
(E) Systems utilized for such processing shah be
designed as a treatment system, as described in
Subsetion (e)(3) of this Section. If a total
containment system is utilized, the system shah
be designed to handle the maximum anticipated
pressure of release to the system when the system
reaches equilibrium.
(2) Gas Cabinets. When gas cabinets are p~ovided
they shall be:
(A) Operated at negative pressure in relation to
the surrounding area.
(B) Provided with self-closing limited access
ports or fire-rated windows to give access to
equipment controls. The average velocity of
ventilation at the face of access ports or windows
shall be not less than 200 feet per minute (fpm)
with a minimum of 150 fpm at any other point of
the access port or window.
Rev. 5/15/90 -17-
(C) Connected to a treatment system.
(D) Provided with self-closing doors.
(E) Constructed of steel with a thickness not
less than 12-gauge.
(3) Treatment systems,
(A) Treatment systems shall be utilized to
process all exhaust ventilation to be discharged
from gas cabinets, exhausted enclosures or
separate storage rooms. Treatment systems shall
be designed to reduce the maximum allowable
discharge concentation of the gas to one-half
IDLH at the point of discharge to the atmosphere
as specified in Subsections (e) (5) and (6) below.
(B) When more than one gas may be emitted to
the treatment system, the treatment system shall
be designed to handle the worst case release
based on the release rate, the quantity and the
IDLH for all the gases stored or used.
(4) Treatmeat system sizing. Treatment systems
shall be sized to process the worst case release of each
gas based on the maximum flow rate of release from
the cylinder or tank utilized which presents the highest
potential hazard. The entire contents of tanks and
cylinders shall be considered.
(5) Stationary tanks.
(A) Stationary tanks shall be labeled with the
maximum rate of release for the gas contained
based on any valves or fittings that are inserted
directly into the tank.
(B) If multiple valves or fittings are provided,
the maximum flow rate of release for the valve or
fitting with the highest flow rate shall be
indicated. If liquefied gases are in contact with
any valve or fitting, the liquid flow rate shall be
utilized for purposes of computation of the
maximum flow rate of release. All flow rates
indicated on the label shah be converted to cubic
feet per minute of gas at normal temperature and
pressure.
(6) Portable tanks and cylinders.
(A) For portable tanks and cylinders, the
maximum flow rate of release shall be calculated
Rev. 5/15/90 -18-
based on assuming the total release from the
cylinder or tank within the time specified in the
Table below:
Nonliquefied Liquefied
Containers (Minutes) (Minutes)
Cylinders 5 30
Portable Tanks 40 240
(B) When portable tanks or cylinders are
equipped with approved reduced flow valves, the
worst case release will be determined by the
maximum achievable flow from the valve as
determined by the valve manufacturer or the gas
supplier. Reduced flow and excess flow valves
shall be permanently marked to indicate the
maximum design flow rate. Such markings shall
indicate the flow rate for air under standard
conditions.
(7) Gas Detection for D.O.T. PoLson A. A portable or
fixed gas detection system capable of monitoring at
PEL for each regulated material classified as a.D.O.T.
Poison A stored or used within the facility shall be
provided.
(f) Exterior Storage.
(1) General. Persons responsible for a facility where
there is exterior storage of any regulated material shah
comply with the provisions of this Subsection (f) and the
Uniform Building Code.
(2) Distance Limitation to Exposures. Exterior
storage of regulated materials shah not be within 75
feet of a building, structure, property line, street,
alley, public way or exit to a public way unless the
storage is shielded by a structure which has a minimum
fire resistire rating of two hours and which interrupts
the line of sight between the storage and the exposure.
The shielding structure shah be at least five (5) feet
from any exposure. The shielding structure shah have
not more than two sides which shall be at
approximately 90-degree directions.
(3) Openings in Bunclings Subject to Exposure., When
an exterior storage area is located within 75 feet of a
building, openings into the building other than piping
shah not be above the height of the top of the shielding
