1.3G Fireworks Storage Magazines Regulations & Requirements


Learning what the proper way to store ATF regulated 1.3G Fireworks is the best way to stay in compliance for safety in storage magazines.

In general, there are three main types of commercial fireworks. These three categories of devices are closely regulated by several government agencies, with special focus on the the Department of Alcohol, Tobacco, and Firearms.


Display fireworks are the large and grandiose type of displays usually utilized in professional fireworks displays. These shows are closely supervised by a trained pyrotechnician. This type of firework produces a visible and / or audible effect in the form of combustion, deflagration, or deterioration. This includes all fireworks falling under the following distinctions;

Containing more than 2 grains (130 mg.) of flash powder

  • Aerial shells containing more than 40 g. of pyrotechnic compositions
  • Display pieces which exceed the limits of explosive materials classified as “consumer fireworks
  • Fused set pieces containing components which together exceed 50 mg, of flash powder

These fireworks are all classified under the Department of Transportation under UN0333, UN0334, and UN0335, and must be transported under the guidlines set aside for fireworks.

To be in possession of such fireworks, one must have procured an ATF Federal Explosives License in compliance with 27 CFR, Part 555.


Commercial fireworks are the standard type of fireworks one will find readily available in stores and roadside stands. These fireworks are small, and commercially available to the general public. These include;


  • Ground devices containing 50 mg. or less of flash powder
  • Aerial devices containing 130 mg. or less of flash powder.

While commercial fireworks are not regulated by the ATF, they are still classified by the Department of Transportation as products UN0336 and UN0337, and any person manufacturing consumer fireworks for commercial use MUST obtain a Federal Explosives Manufacturing License.


These particular devices are pyrotechnic devices manufactured for professional use. They are similar to commercial fireworks in chemical composition and construction, but are not intended for consumer use. These devices also fall under the regulation of 27 CFR 555.11.


The Code of Federal Regulations (CFR) has a five type distinction for the storage of explosives. All of these distinctions of type are governed by the storage rules as laid down in CFR Part 555.206 (Location of magazines), CFR 555.207 (Construction of Type 1 Magazines),CFR 555.208 (Construction of Type 2 Magazines), CFR 555.209 (Construction of Type 3 Magazines), CFR 555.210 (Construction of Type 4 Magazines), CFR 555.211 (Construction of Type 5 Magazines), and CFR 555.213 (Quantity and Storage Restrictions).

The types of explosives regulated under the Code of Federal Regulations Part 555 are defined as such;

Type 1 Magazines: Permanent storage for high explosives. Subject to CFR 555.206 and CFR 555.213 limitations. Other classes of explosives may also be stored.

    1. Type 2 Magazines: Mobile or portable indoor and outdoor storage for high explosives subject to limitations under CFR 555.206, CFR 555.208, and CFR 555.213.
    2. Type 3 Magazines: Portable outdoor magazines for storage of high explosives while attended (ex: a “day box”), subject to limitations for CFR 555.206, and CFR 555.213. Other classes may also be stored.


  • Type 4 Magazines: Low explosives. Subject to the limitations presented by CFR 555.206, CFR 555.210, and CFR 555.213. Detonators that will not mass detonate may also be stored.
  • Type 5 Magazines: Blasting agents. These agents are subject to CFR 555.206, CFR 555.211, and CFR 555.213.




The aviation industry is rife with numerous chemicals, compounds and ejection-seat-storage-magazines-dayboxmaterials  that qualify as either “flammable”, or “combustible” , or “explosive” according to The National Fire Protection Association standard 30 (NFPA 30). According to NFPA 30, a “flammable” liquid is any chemical that has a flashpoint below 100 degrees Fahrenheit, while a “combustible” liquid is any chemical that has a flashpoint above 100 degrees Fahrenheit.

The most commonly encountered NFPA 30 chemicals that are encountered in the aviation industry are; acetone, ammonia, asbestos, carbon monoxide, chlorofluorocarbon 113 (CFC 113), ethylene glycol, methylene chloride, and methyl ethyl ketone (MEK). More chemicals can be found for all industries listed on the Materials Safety Data Sheet (MSDS), which should be on site at any facility storing any of the 0ver 4,000 chemicals listed on this list.

Aviation chemicals may be stored by four separate methods; aboveground tanks, below ground tanks, storage tank buildings, and container / locker storage. All aviation chemicals to be stored in a container / locker MUST adhere to NFPA 30 Sec. 9.5.3 which states that a “flammable storage cabinet” must be designed to limit the internal temperature of the container / locker to no more than 325 degrees Fahrenheit from the center of the cabinet to within 1” of the top of the cabinet when subject to a 10 minute fire test.

Aircraft Ejection Seats & Explosives Storage

Certain materials used in aircraft ejection seats may be required to be stored in qualified storage magazines, day boxes or Type 2, Type 3 or Type 4 cabinets and boxes. These may include cartridge activated explosive devices, boosters, or impulse cartridges. 

Cartridges are typically stored where they are not exposed to direct sun or high temperatures, this generally means storage in a cool, dry place or storage magazine. Local jurisdiction will provide requirements for storage of percussion-fired cartridges.

Large quantity storage regulations for propellants, pyrotechnics and explosives may include fire walls, operational shields, substantial dividing walls, blast resistant roofs, containment structures, and earth-covered magazines in accordance with NASA-STD-8719.12


Acetone – Acetone is an organic compound that is extremely flammable. It is used as a solvent, and in the degreasing process. Primary aviation uses are in the area of painting and buffing of aircraft.

Ammonia – Ammonia is a colorless compound of nitrogen and hydrogen with a very pungent odor. It’s primary uses in the aviation industry is the base ingredient in many aviation cleaning products.

Asbestos – Asbestos derives from a group of chemicals occurring naturally in the environment that can be separated into thin, durable threads. These threads are resistant to heat, fire, and chemicals, and do not conduct electricity. Prior to the 1980s, asbestos was found many places in the aviation industry including the engine, insulation, brakes, cockpits, heating systems, heat shields, torque valves, gaskets, electrical wiring, and insulation. Once the carcinogenic effects of asbestos were thoroughly examined, the aviation industry began to phase out the product. It is not very rarely found, and then predominantly in adhesives and epoxies.

Chlorofluorocarbon 113 – (CFC 113) CFC 113 s a organic compound formed from carbon, chlorine, and fluorine, and is produced as a volatile derivative of methane, ethane, and propane. CFC 113 is commonly known by its DuPont trademark name “Freon.” CFC 113 is used in aviation primarily as a refrigerant. Use of CFC 113 was severely curtailed in the 1980s when its negative effects on the ozone layer were discovered.

Ethylene glycol – Ethylene glycol is a colorless, odorless, sweet tasting syrup that is used in the manufacture of polyester fibers and antifreeze. It is used in aviation primarily as the main component for de-icing fluid.

Methylene chloride – Methylene chloride (commonly known as Dichloromethane, or “DCM”), is a colorless, odorless, volatile organic compound with a moderately sweet aroma that is predominantly used as a solvent. The primary uses of DCM in the aviation industry are as a paint stripper, degreaser, and aerosol propellant.

Methyl ethyl ketone (MEK) – MEK (commonly known as butanone) is a colorless organic compound with a sharp, sweet odor reminiscent of butterscotch and ammonia. It is commonly used as a solvent, and plastic welding agent. Its primary use in aviation is as a cleaner for bare metal surfaces.

The Library below is meant for educational purposes on technical information of many explosives that our magazines are used for in compliance with safety & explosive hazards regulations.

AMMONIUM NITRATE – Composed of the nitrate salt of ammonium, this white crystalline solid is highly water soluble. Ammonium nitrate is predominantly used in agriculture as a high nitrogen fertilizer. One other major use of ammonium nitrate is as an explosive in mining, quarrying, and civil construction. Ammonium nitrate is the main component of ANFO (ammonium nitrate / fuel oil), which accounts for 80% of all explosives used in North America.

CAST BOOSTERS – Cast boosters are used to amplify the energy of a detonator. The booster acts as a conduit between a weak conventional detonator, and a low sensitivity explosive. (Ex: TNT). The most common form of cast booster is a cylindrical shell made of extruded or pressed cardboard or plastic which the explosive material has been cast into.

Safe and ATF compliant storage for High and Low Explosives in the workplace or worksite.

DELIVERY SYSTEMS – A delivery system is a generic term used to describe the method in which an explosive charge is ignited. 95% of all explosives are delivered into the borehole by bulk loading methods.
DETONATING CORD – Also known as a detonation cord, detacord, detcord, primer cord, or sun cord, the detonating cord is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN). The cord is a high speed fuse which explodes, rather than burning. Detonation cords are used for detonating high explosives, and act as a downline between the trigger and the blast area.

ELECTRIC DETONATORS – An electric detonator allows a circuit to be tested before firing a shot. Electric detonators come in three categories; instantaneous electric detonator (IED), short period delay detonators (SPD), and long period delay detonators (LPD). The detonation of SPDs are measured in milliseconds, while the detonation of LPDs are measured in seconds.

ELECTRONIC DETONATORS –  Electronic detonators offer better precision for delayed ignition. These detonators are designed to provide precise control to produce accurate and consistent blasting results. Electronic detonators are primarily used in mining, quarrying, and construction. These detonators are programmed in one millisecond increments from 1 millisecond to 10,000 milliseconds.

EMULSIONS – Emulsions are explosives composed of water in oil based explosives. Emulsion explosives are ideal for bulk loading both on the surface and underground. Emulsions are the most commonly used explosive based on ammonium nitrate / fuel oil (ANFO) chemistry. These explosives are water resistant, and offer a higher bulk density.
NON-ELECTRIC DETONATORS – Non-electric detonators are shock tube detonators used to initiate explosions. A hollow plastic tube delivers a firing impulse to a detonator instead of electric wires. This makes non-electric detonators immune to most hazards associated with stray electrical current. A non-electrical reaction travels at approximately 6,500 feet per second along the length of the tube with minimal disturbance outside of the tube.
