CODE REQUIRMENT FOR BULK RESIN
STORAGE
In the following paragraphs we will attempt to explain the national fire codes for storage
of polyester resin that are Class 1, Division II Stable Liquids with a specific gravity
greater than 1. These codes will cover inside and outside bulk storage.
In this explanation we will reference several publications:

Most agencies use the above mentioned codes as guidelines, but there may also be local
differences in interpretation. It is very important to have the input of local agencies. We
stress to our clients the need to consult with the local and/or State Fire Marshall, and
insurance carrier. In most code books you will see the term "The authority Having
Jurisdiction." The "Authority Having Jurisdiction" is the organization, office or
individual responsible for "approving" equipment, an installation or a procedure.
NOTE: The phrase "authority having jurisdiction" is used in NFPA documents in a broad
manner. Several jurisdictions and "approval' agencies may have varying responsibilities
for a given installation. Where public safety is of primary concern, the "authority having
jurisdiction" may be a federal, state, local or other regional department, health
department, building inspector, electrical inspectors or others having statutory authority.
For insurance purposes, an insurance inspector, rating bureau or other insurance company
representative may be the "authority having jurisdiction." In some circumstances, such as
a Federal Installation, the property owner or designated agent assumes the role of the
"authority having jurisdiction"
Our intent is to make all installation as safe as we know how, and to conform to all safety
requirements, codes and statutes.

(gauge pressure of 17.2 kPa) under emergency venting conditions.
Notes:
1. The fifth tank listed in 21.4.2.1.1 (5) is a UL 58 which is for underground tanks. We
do not recommend underground storage of polyester due to the new EPA
Regulations. Please consult CFR40 Parts 280 to 282 Underground Storage Tank
Technical Requirements and State Program Approval. Final Rule. Also please consult
EPA 530 UST-88/005 and EPA 530 UST-88/008.
2. The sixth (6) tank listed is UL80 which is for inside tanks for oil burner fuel, which
does not apply.
The seventh (7) tank listed in this sub -paragraph are described in UL142, UL2080 and
UL2085 section 1.1 These requirements cover shop fabricated, aboveground atmospheric
and Fire Resistant Tanks intended for storage of stable flammable or combustible liquids
that have a specific gravity not greater than 1.0 and that are compatible with the material
and construction of the tank.
Page 3.
As you can see by this paragraph, it immediately disallows these specifications for
polyester resin use, because of the high specific gravity of the resin which is 1.1 to
1.4. A UL142, UL2080 and UL2085 type of tank does not have the structural
strength to hold polyester resin.
3. NFPA-30: Section 21.4.2.1.1 (4) refers to the American Petroleum Institute Standard
No. 650, Welded Steel Tanks for Oil Storage. This specification, in combination with
the guidelines in NFPA 30 will provide an acceptable design, in most cases. NFPA 30
references API-650 in Exception No. 1 Atmospheric tanks that are not designed and
constructed in accordance with Appendix F of API Standard 650, Welded Steel Tanks
for Oil Storage, shall be permitted to operate at pressures from atmospheric to 1.0
psig (gauge pressure of 6.9 kPa) only if an engineering analysis is performed to
determine that the tank can withstand the elevated pressure.
NFPA-30: Section 21.4.2.1.1 (8) refers to UL-1316 this is a glass fiber reinforced plastic
storage tank for underground use. Please consult the EPA Regulations cited in note 1
above.
NFPA-30: Section 21.4.2.1.1 (9) refers to UL-1746 refers to external corrosion protection
systems for underground storage tanks. Please consult the EPA Regulations cited in note
1 above.
(CFR) Title 29-Labor Part 1910 Under Tank storage:
(f) Special engineering consideration shall be required if the specific gravity of the liquid
to be stored exceeds that of water or if the tanks are designed to contain flammable or
combustible liquids at a liquid temperature below 0 F.
In summing up this section, the only specifications that can be applied are API-
650. API-650 is an above ground tanks, we can use their design requirements in
Appendix J to determine the appropriate structural strength. This is the standard that we
use to design our storage tanks along with all the safety requirements in NFPA-30.
Note:
Some people ask for double -walled aboveground storage tanks. The only standard for
these types of tanks are UL-142, UL-2080 and UL-2085. Section 1.1 in these codes reads
as follows: These requirements cover shop fabricated, aboveground atmospheric and Fire
Resistant Tanks intended for storage of stable flammable or combustible liquids that have
a specific gravity not greater than 1.0 and that are compatible with the material and
construction of the tank. As you can see by this paragraph, it immediately disallows these
specifications for polyester resin use, because of the high specific gravity of the resin
which is 1.1 to 1.4. A UL142, UL2080 and UL2085 type of tank does not have the
structural strength to hold polyester resin.
The requirements of IFC and NFPA 30 must be included to develop the appropriate
fitting designs. Particular attention must be paid to the following sections:
1. IFC: 3404.2.7.5.5 & NFPA-30: 21.4.4
Page 4.
Fill pipes and discharge lines. For top -loaded tanks, a metallic fill pipe shall be
designed and installed to minimize the generation of static electricity by terminating
the pipe within 6 inches of the bottom of the tank, and it shall be installed in a manner
which avoids excessive vibration.
2. IFC: 3404.2.7.4
Emergency venting. Stationary, aboveground tanks shall be equipped with additional
venting that will relieve excessive internal pressure caused by exposure to fires.
Emergency vents for Class I, II and IIIA liquids shall not discharge inside buildings.
The venting shall be installed and maintained in accordance with section 4.2.5.2 of
NFPA-30.
NFPA-30: 22.7 Emergency relief venting for fire exposure for aboveground tanks
22.7.1.1 Every aboveground storage tank shall have emergency relief venting in the
form of construction or a device or devices that will relieve excessive internal
pressure caused by an exposure fire.
22.7.1.1.2 This requirement shall also apply to each compartment of a
compartmented tank, the interstitial space (annulus) of a secondary containment -type
tank, and the enclosed space of tanks of closed -up dike construction. This
requirement shall also apply to spaces or enclosed volumes, such as those intended
for insulation, membranes, or weather shields, that can contain liquid because of a
leak from the primary vessel and can inhibit venting during fire exposure. The
insulation, membrane, or weather shield shall not interfere with emergency venting.
22.7.1.1.3 Tanks storing Class IIIB liquids that are larger than 12,000 gal (45,400 L)
capacity and are not within the diked area or the drainage path of tanks storing Class I
or Class II liquids shall not be required to meet the requirements of 22.7.1.1.
NFPA-30: 22.7.1.2 For vertical tanks, the emergency relief venting construction
referred to in 22.7.1.1 shall be permitted to be a floating roof, a lifter roof, a weak
roof -to -shell seam, or another approved pressure -relieving construction.
22.7.1.3 Weak Roof -to -Shell Seam Construction.
If used, a weak roof -to -shell seam shall be constructed to fail preferential to any other
seam and shall be designed in accordance with API Standard 650, Welded Steel
Tanks for Oil Storage, or UL 142, Standard for Steel Aboveground Tanks for
Flammable and Combustible Liquids.
Notes:
Emergency Venting Capacity for our tanks:
The formula given:
Cubic feet of free air per hour = V x 1,337/ L x SQR (M)
The tank in question has a total surface area Of 550 sq. ft.
Per NFPA-30 22.7.3.2.2 (2) you only use 75% for table 22.7.3.2 or 480 sq. ft.
This gives a requirement for 354,000 cu. ft.
The next item in the formula is the Latent heat of Vaporization of Styrene. This is
102.4 calories per gram or 184 BTU per pound.
Page 5.
The last item in the formula is the Molecular weight of Styrene 104.14.
The Formula works as follows:
354,000 x 1,337/ 184 x SQR (104.14)
354,000 x 1,337/ 184 x 10.2
354,000 x 1,337/1,877
354,000 x .712 = 252,048
This gives a required venting capacity of 252,048 cubic feet of free air per hour. If you
further realize we are dealing with a Resin Solution of only 35% Styrene, we have a
significant safety margin.
3. IFC: 3404.2.7.3 Tank vents for normal venting.
Tank vents for normal venting shall be installed and maintained in accordance with
sections 3404.2.7.3.1 through 3404.2.7.3.6
NFPA-30: 21.4.3 Normal venting for storage tanks.
NFPA-30: 21.4.3.1 Atmospheric Storage tanks shall be vented to prevent the
development of vacuum or pressure that can distort the roof of a cone roof tank or
that exceeds the design pressure of other atmospheric tanks when filling or emptying
the tank or because of atmospheric temperature changes.
NFPA-30: 21.4.3.2 Normal vents shall be sized in accordance with either API
Standard 2000, Venting Atmospheric and Low -Pressure Storage Tanks, or another
approved standard. Alternatively, the normal vent shall be at least as large as the
largest filling or withdrawal connection but in no case shall it be less than 1.25-in.
(32-mm) nominal inside diameter.
NFPA-30: 21.4.3.9 Flame arrestors or venting devices required in 21.4.3.6 and
21.4.3.7 shall be permitted to be omitted on tanks that store Class IB or Class IC
liquids where conditions are such that their use can, in case of obstruction, result in
damage to the tank. Liquid properties justifying the omission of such devices include
but are not limited to, condensation, corrosiveness, crystallization, polymerization,
freezing, or plugging. When any of these conditions exist, consideration shall be
permitted to be given to heating, use of devices employing special materials of
construction, the use of liquid seals, or inerting.
The codes explanation for the variance makes reference to the importance of frequent
vent inspection. Because of the way polyester resin does polymerize, our design allows
for easy removal of the vents for inspection and cleaning as necessary. Also with our
filling procedure they are checked each time the tank is filled.
4. IFC: 3404.2.7.5.8 Overfill prevention.
An approved means or method in accordance with section 3404.2.9.6.6 shall be
provided to prevent the overfill of all Class I, II and IIIA liquid storage tanks.
Page 6.
IFC: 3404.2.9.6.6 Overfill prevention.
Protected aboveground tanks shall not be filled in excess of 95 percent of their
capacity. An overfill prevention system shall be provided for each tank. During tank -
filling operations, the system shall:
Provide an independent means of notifying the person filling the tank that the fluid
level has reached 90 percent of tank capacity by providing an audible or visual alarm
signal, providing a tank level gauge marked 90 percent of tank capacity, or other
approved means.
A filling procedure shall require person filling the tank to determine the gallonage
required to fill it to 90 percent of capacity before commencing the fill operation.
Our tank systems have load cells that displays the weight of the fluid in the tank at all
times. Also the system has low and high level alarms that are audible and visual. This
is the only way that we have found in are years of installing resin storage tank to keep
track of the material in each tank. This along with are filling procedure will stop the
over filling of the tanks.
IFC: 3404.2.9.6.4 Secondary containment.
Protected aboveground tanks shall be provided with secondary containment, drainage
control or diking in accordance with section 2704.2. A means shall be provided to
establish the integrity of the secondary containment in accordance with NFPA-30.
NFPA-30: 22.11 Control of spill from aboveground tanks.
Every tank that contains a Class I, II or IIIA liquid shall be provided with means to
prevent an accidental release of liquid from endangering important facilities and
adjoining property or from reaching waterways. Such means shall meet the
requirements of 22.11.1, 22.11.2, 22.11.3, or 22.11.4, whichever is applicable.
NFPA-30: 22.11.2.2 The volumetric capacity of the diked area shall not be less than
the greatest amount of liquid that can be released from the largest tank within the
diked area, assuming a full tank.
22.11.2.2.1 To allow for volume occupied by tanks, the capacity of the diked are
enclosing more than one tank shall be calculated after deducting the volume of the
tank, other than the largest tank, below the height of the dike.
6. MC: 3404.212 Testing.
Tank testing shall comply with sections 3404.2.12.1 and 3404.2.12.2
IFC: 3404.2.12.1 Acceptance testing. Prior to being placed into service, tanks shall be
tested in accordance with section 4.4 ofNFPA-30.
NFPA-30: 21.5 Testing requirements for tanks.
NFPA-30: 21.5.1 Initial testing. All tanks, whether shop -built or field -erected, shall
be tested before they are placed in service in accordance with the applicable
requirements of the code under which they were built.
Page 7.
NFPA-30: 21.5.1.1 An approved listing mark on a tank shall be considered to be
evidence of compliance with this requirement. Tanks not so shall be tested before
placed in service in accordance with recognized engineering standards or in
accordance with the requirements for testing in the codes listed in
21.4.2.1.1,21.4.2.2.1 or 21.4.2.3.1.
NFPA-30: 21.5.2.3 Horizontal shop -fabricated aboveground tanks shall be tested for
tightness either hydrostatically or with air pressure at not less than 3 psig and not
more than 5 psig.
Our tanks are horizontal shop -fabricated aboveground tanks, we test each unit at 3
psig and not only do we mark the tank but we also give a testing certificate with all
the test data.

Overfill protection shall be provided in accordance with section 3404.2.9.6.6.
As you can see by the codes, its almost impractical to put a tank inside a building or
enclosure. The cost for the engineering, monitoring and detection equipment, fire
protection, ventilation and electrical would be quite high as compared to an outside
tank system. Keep in mind these are just the fire codes, there are other federal and
state regulations that do apply to storage tanks being placed inside. Also your
insurance carrier may have special guide lines that you will need to follow.

interlocks to prevent over pressure.
1. We install cast iron positive -displacement gear pumps with pressure relief
discharging back to the pump suction. These are electric pumps that are made for
Class I locations with overloads and thermal interlocks.
2. An air -operated diaphragm pump does not meet IFC: 3405.2.1. Also with the way
Fire Marshall's are reading the codes, many states have ruled that this type of
pump: In a fire 1. The diaphragms and exhaust vent melt, which will allow the
material to feed the fire. 2. The air in which operates the pump can add to that
fire.
3. Although under UL specification 79 they have this type of pump on portable fuel
tanks for small equipment, they are not meant to be used on bulk storage tanks.
4. Even if you put a thermal safety valve on before the pump, because of the fact
that the way polyester resin does polymerize it will stick open and will let the
resin pass -by to feed the fire.
5. Code of Federal Regulations Title 29-Labor:
CHAPTER XV1I--OCCUPATIONAL SAFETY AND HEALTH
ADMINISTRATION, DEPARTMENT OF LABOR
PART 1910--OCCUPATIONAL SAFETY AND HEALTH STANDARDS

process equipment, gravity flow shall not be used. The use of compressed air as a
transferring medium is prohibited.
(b) Positive displacement pumps shall be provided with pressure relief discharging
back to the tank or to pump suction.
Page 19.
What about the Grandfather Clauses?
We all know the genesis of the term "Grandfather" as it relates to codes and
standards. The "Grandfather" clause is a phase used in code terminology that speaks
to a condition existing before or at the time a requirement is enacted that allows that
condition to exist without mandating compliance. Unfortunately, the fact that any
number of these changes cited can and do create hazardous or unsafe conditions in a
systems we once thought were state of the art in terms of fire protection. Let's
understand one thing right from the start, "Grandfather" clauses were never meant to
allow unsafe conditions or circumstances to exist in any system that would put the life
of workers or occupants at risk regardless of its age or how long it has been in
service. The problem arises when we recognize that a hazard does exist, and
understand that something needs to be done about it. Waiting for a tragedy to become
the impetus for these changes is not an option. So if you think you might be in this
type of circumstance, please have an inspection so that problems can be identified and
take the necessary action to correct the problem.
The definitions of "flammable liquid" and 'combustible liquid" in NFPA 30 differ
from those used by the U.S. Department of Transportation. Why?
Definition and classification of flammable and combustible liquids are addressed in
Section 1.7 of NFPA 30. A flammable liquid is defined as a liquid whose flash point
does not exceed 100°F, when tested by closed -cup test methods, while a combustible
liquid is one whose flash point is 100°F or higher, also when tested by closed -cup
methods. These broad groups are further classified as follows:
• Class IA - Flash Point less than 73°F; Boiling Point less than 100°F
• Class IB - Flash Point less than 73°F; Boiling Point equal to or greater than
100°F
• Class IC - Flash Point equal to or greater than 73°F, but less than 100°F
• Class II - Flash Point equal to or greater than 100°F, but less than 140°F
• Class-IIIA - Flash Point equal to or greater than 140°F, but less than 200°F
• Class IIIB - Flash Point equal to or greater than 200°F
Notice that boiling point is only used to distinguish between ClassIA and Class IB.
Class IA liquids are extremely volatile, but there are few liquids that are so classed.
Note also that, theoretically, there is no upper limit to Class IIIB.
These definitions and classifications were agreed to years ago by NFPA, the U. S.
Department of Transportation (DOT), and the U. S. Occupational Safety and Health
Administration (OSHA) in an attempt to remove inconsistencies in the definitions
Page 20.
used at the time. Since then, DOT has changed its definition of "flammable liquid" by
raising the upper limit to 141°F (60.51C). This was done because the United States is
a partner to a world-wide set of hazardous materials regulations sponsored by the
United Nations and must use the UN definitions, at least for international
transportation. Note, however, that DOT regulations include a so-called "domestic
exemption" that allows a shipper to redesignate as a combustible liquid any liquid
whose flash point is in the NFPA Class II range and which does not meet any other
hazardous material definition.
Just remember Authority Having Jurisdiction can rule on any and all of these codes.
So if you are given a variance, make sure that it is done in writing. These are just
some of the key regulations and statutes that we use to insure that our systems are up
to code. Please remember to consulate not only your state Fire Marshall, but also your
insurance carrier, and any other agency that may have regulations for aboveground
storage tanks in your area.
We have a list for each states ASTs to help owners and operators understand the
related technology, federal and state regulations, codes and standards and related
issues with storing and handling polyester resin.
Also you should read the Code of Federal Regulations Title-29 Part-1910.106, these
codes are the ones for Flammable and Combustible Liquids and Title40 Part-112,
these are the code for Protection of Environment and Applicability, Definitions, and
General Requirements for All Facilities.
