Flash Point is:Lowest temperature at which sufficient vapor is given off to form ignitable mixture w/air

Flash Point Classification

NFPA 30 Manages Risk Of Flammable And Combustible Liquids By Their Flash Point Classification

There are two classifications systems you need to be aware of:

• NFPA 30 section 4.3.1 (flammable liquids) & 4.3.2 (combustible liquids)

• OSHA 29CFR 1910.106(a)(19)

• Per GHS Labeling

• & GHS Safety Data Sheet (SDS)

• It is important to cross reference from the labels/SDS sheets of material received into NFPA 30’s classification to apply the NFPA 30 Code, NFPA 1 Code etc.…

Quick Note:

1) Gasoline has traditionally been a Class 1B flammable liquid but, with some of the newer oil extraction techniques and formulation, gasoline can be a Class 1A flammable liquid. Check your SDS sheet. Meaning you might need a maximum 2.6 gallon safety can maximum instead of 5.3 gallon maximum.

2) A 2 gallons maximum safety can is allowed per OSHA’s Category 1 (Class 1A - NFPA).

(using maximum 2.6 gallons safety cans would likely be considered de minimis per OSHA.)

9.4 Acceptable Containers.

3) Nonmetallic or metallic commercial/industrial safetycans meeting the requirements of, and used within thescope of, one or more of the following specifications:

(a) ANSI/UL 30, Standard for Metal Safety Cans(b) ANSI/UL 1313, Standard for Nonmetallic Safety Cans for Petroleum Products(c) FM Global Approval Standard for Safety Containers and Filling, Supply, and Disposal Containers —Class Number 6051 and 6052

9.5* Flammable Liquids Storage Cabinets.9.5.3 Storage cabinets that meet at least one of the following sets of requirements shall be acceptable for storage of liquids:(1) Storage cabinets designed and constructed

to limit the internal temperature at the center of the cabinet and 1 in. (25 mm) from the top of the cabinet to not more than 325°F (163°C), when subjected to a 10-minute fire test that simulates the fire exposure of the standard time– temperature curve specified in ASTM E119, Standard Test Methods for Fire Tests of Building Construction and Materials, shall be acceptable. All joints and seams shall remain tight and the door shall remain securely closed during the test.

And/Or constructed as follows



Quick note on maximum 325 °F :

1. Typical auto ignition temperatures of flammable & combustible liquids: ethanol = 689°F, gasoline = 475°F (246°C), jet fuel = 410°F (210°C) , kerosene 428°F (220°C), methyl alcohol = 867°F (462°C) etc…

2. Auto ignition outlier* of Carbon Disulfide at 194°F (90°C)

9.5* Flammable Liquids Storage Cabinets.

Metal storage cabinets constructed in the following manner shall be acceptable:(a) The bottom, top, door, and sides of the cabinet shall be at least No. 18 gauge sheet steel and shall be double-walled, with 1 1/2

in. (38 mm) air space.(b) Joints shall be riveted, welded, or made tight by some equally effective means.(c) The door shall be provided with a three-point latch arrangement, and the door sill shall be raised at least 2 in. (50 mm) above the bottom of the cabinet to retain spilled liquid within the cabinet.

And/or constructed as follows


Venting a Safety Cabinet


9.5.4* Storage cabinets shall not be required by this code to be ventilated for fire protection purposes.

9.5.4.1 If a storage cabinet is not ventilated, the vent openings shall be sealed with the bungs supplied with the cabinet or with bungs specified by the cabinet manufacturer.

9.5.4.2* If a storage cabinet is ventilated for any reason, the vent openings shall be ducted directly to a safe location outdoors or to a treatment device designed to control volatile organic compounds (VOCs) and ignitable vapors in such a manner that will not compromise the specified performance of the cabinet and in a manner that is acceptable to the authority having jurisdiction.

A.9.5.4 Venting of storage cabinets has not been demonstrated to be necessary for fire protection purposes. Additionally, venting a cabinet could compromise the ability of the cabinet to adequately protect its contents from involvement in a fire, because cabinets are not generally tested with any venting. Therefore, venting of storage cabinets is not recommended.

However, it is recognized that some jurisdictions might require storage cabinets to be vented and that venting can also be desirable for other reasons, such as health and safety. In such cases, the venting system should be installed so as to not affect substantially the desired performance of the cabinet during a fire. Means of accomplishing this can include thermally actuated dampers on the vent openings or sufficiently insulating the vent piping system to prevent the internal temperature of the cabinet from rising above that specified. Any make-up air to the cabinet should also be arranged in a similar manner.

If vented, the cabinet should be vented from the bottom with make-up air supplied to the top. Also, mechanical exhaust ventilation is preferred and should comply with NFPA 91. Manifolding the vents of multiple storage cabinets should be avoided.

Venting a Safety CabinetMy recommendations:

1. Retain a professional engineer. 2. Consult with the AHJs.3. Planning/design should consider the possible conveyance of: ignitable vapors, ignitable

gases, or ignitable dust based on material being stored. 4. Cabinet bungs accommodate 2” NPT threaded schedule 40 steel pipe for ductwork.5. Use black steel, galvanized steel or stainless steel schedule 40 steel pipe 6. Avoid PVC, CPVC. ABS, Polypropylene pipe etc.. 7. Ground vented safety cabinet and duct work when required. 8. Evacuate vapors from the cabinet using negative pressure (suction). 9. An air exchange of 1 ft3/min/ft2 (5.1 L/s/m2) of floor area is recommended 10. Blowers should be specified for hazardous locations as required by the material stored.

(Electrical equipment: Class 1 Division 2, Art 500 of NFPA 70)11. Blowers should shut down in the events of a fire. 12. Most flammable vapors are heavier than air, draw from the bottom. bung and provide

fresh air through the top bung.
