ATF Regulations for Police Department Explosive Storage: Type 2 & Type 3 Magazines

Police departments handling explosives for bomb squads, evidence storage, or training must comply with Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) regulations to ensure security and safety. Among the different types of storage solutions, Type 2 and Type 3 magazines are commonly used by law enforcement for secure and temporary explosive storage.

Understanding ATF storage requirements and choosing the right storage solution is essential for compliance and risk mitigation.

ATF Regulations for Explosive Storage

The ATF regulates explosive storage under 27 CFR Part 555, Subpart K, which outlines specific requirements for construction, security, and placement of explosive magazines. Police departments must comply with these laws to prevent unauthorized access, theft, or accidental detonation.

ATF Federal Explosives Storage Magazine Requirements

ATF Federal Explosives regulations noted in 27 CFR Part 555 Subpart K specify detailed construction requirements for explosive magazines. All explosive material MUST be kept in locked magazines UNLESS:

In the process of manufacture
Physically handled by a licensee or user during the operating process
Currently in use
In transport to a place of storage or use by a licensee, permittee, or an individual who lawfully and legally acquired explosive materials under Section 106 Subpart F

Explosive materials MUST be kept in magazines that meet the construction, locking, and specified table of distance requirements noted in Subpart K. When none of the specified conditions and standards listed above apply:

All explosive materials must be stored in appropriate magazines
Magazines must meet construction and housekeeping fulfillments noted in Sections

555.211 & 215

Magazines must meet table of distance requirements presented in Section 218
Magazines must be inspected every 7 days
Permanent outdoor magazines must have a solid foundation or be metal skirted to prevent access from underneath
Explosive materials may not be left unattended in Type-3 magazines (including “day boxes”) and must be removed to Type-1 or -2 magazines for storage
Storage regulations DO NOT apply to binary explosives until mixed

Explosive Types and Storage

High Explosives

High explosives is a function by detonation that causes a rapid decomposition of the material caused by a shock wave moving through the product at a rate faster than the speed of sound. All high explosives (including blasting caps, detonating cord, dynamite, shaped charges, boosters, etc.) in accordance to Section 555.203 must be stored in:

Type-1 Permanent magazines
Type-2 Mobile and portable (indoor/outdoor) magazines
Type-3 Magazines for attended storage

Low Explosives

Low explosives detonate producing a large volume of heated gas. All low explosives in accordance to Section 555.203 (such as black powder, display fireworks, safety fuse, igniters, etc.) must be stored in:

Type-1, -2, or -4 Permanent, portable or mobile (indoor/outdoor) magazines

Blasting Agents

Blasting agents are a material or mixture that consists of fuel and oxidizer that is intended solely for blasting and that cannot be detonated by a No. 8 test blasting cap when unconfined. Blasting agents may be stored** in:

Type-5 Permanent, portable, or mobile (indoor/outdoor) magazines

**Blasting agents stored WITH high explosives must be stored in a Type-1 or -2 magazine

Storage Security

Hinges and Hasps

Hinges and hasps must be attached to storage doors by bolting, riveting, or welding so that the door bolts cannot be removed from the outside.

Locks

Having the appropriate locks will help hinder robberies and break-ins. The ATF recommends that any padlock securing an explosives magazine have an ASTM (American Society of Testing Materials) rating of at least 5.

More information can be found in ASTM’s F883-97 “Standard Performance Specifications for Padlocks”.

General requirements:

Two mortise locks
Two padlocks fastened in separate hasps and staples
Padlocks must have at least five tumblers and a casehardened shackle of at least ⅜-inch diameter
Padlocks must be protected with no less than ¼-inch steel hoods constructed so as to prevent sawing or lever actions on the locks, hasps, and staples
Three-point lock
Combination of mortise lock and padlock
Mortise lock requiring two keys to open

Indoor Magazines

The locking requirements for indoor magazines are similar to outdoor magazines requirements with a few exceptions. An indoor magazine located in a locked secured room with door hinges and lock hasp securely fastened to the magazine (noted in 27 CFR 555.208(b), 555.210(b) and 555.211(b)), may have each door locked with one steel padlock that meets the stated requirements above.

“Hockey Puck” Locks

“Hockey puck” locks have no visible shackle. The locking bolt and staple are completely covered and protected by the lock body. For the locks to be approved for use, the lock must have a casehardened shackle and a close-fitting shroud to prevent sawing or prying of the lock.

Prior to installation, the licensee/permittee must submit a request for a variance.

Flush Mounted Locks

Flush mounted locks (aka “flush-mount lever locks”) do not provide sufficient protection against pulling or prying the lid off the magazine. A flush mounted lock fails to provide an acceptable level of theft-resistance for indoor storage of low explosive materials and may not be used to secure Type-4 indoor magazines. Additional information can be found at ATF Ruling 2004-3.

Licensee and/or permittee who desires to use this type of lock in a secured room that is locked as noted in subparagraph (b) of 27 CFR 555.210 may submit a request for a variance.

Vehicular Magazines for Storage

Type-2, -4, and -5 unattended vehicular magazines must have the wheels removed or otherwise immobilized by kingpin locking devices. Other methods must be approved by the Director.

Magazine Inspections

Magazines must be inspected at least once every 7 days. Inspection must be sufficient to determine if there has been unauthorized or attempted entry
A full inventory of your explosive materials is required annually and entered into your Daily Summary of Magazine Transactions

Bullet Resistance

Federal regulations require that Type-1 and Type-2 explosive magazines be bullet-resistant. “Bullet-resistant” means resistant to penetration by a bullet of 150 grain M2 ball ammunition (nominal muzzle velocity of 2,700 feet per second). Construction requirements for Type-2 outdoor magazines (i.e. exterior and doors constructed of not less than ¼-inch thick steel and lines with at least 2 inches of hardwood) are fixed to guarantee bullet-resistance.

ATF Ruling 76-18 details alternate construction standards for explosive magazines.

Bullet Resistance for Type-2 Indoor Storage

Type-2 indoor magazines do not need to be bullet-resistant if the buildings in which they’re stored in provide protection from bullet penetration. Type-2 indoor magazines have less strict construction regulations due to the additional protection afforded by the associated building (see Part 555.208(b)). Please note that if the magazine, nor the building in which it is located, is bullet resistant, then the magazine and building must meet bullet-resistance requirements.

If there’s a concern that the combined construction doesn’t meet listed requirements and ATF Ruling 76-18 doesn’t address the situation, a licensee or permittee may submit a request for a variance to the requirements contained in 27 CFR 555.208. Variance requestions should be submitted to the Explosives Industry Programs Branch via your local ATF office. When submitting your request for a variance, please include specific construction information for both the magazine and building in which it is located.

1.3G Fireworks Storage Magazines Regulations & Requirements

TYPES OF COMMERCIAL FIREWORKS AND THEIR STORAGE

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

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.

CONSUMER FIREWORKS

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.

ARTICLES PYROTECHNIC

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.
STORAGE MAGAZINE DISTINCTIONS FOR FIREWORKS STORAGE

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.

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.
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.

STORAGE OF FLAMMABLES, COMBUSTIBLES & EJECTION BOOSTERS IN AVIATION

The aviation industry is rife with numerous chemicals, compounds and materials 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

COMMON AVIATION CHEMICALS AND THEIR INDUSTRY USES

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.

BLENDED NITRIC ACID (BNA) – Blended nitric acid is a clear and colorless (to slightly yellow) liquid that can come in varying strengths. BNA is created by oxidizing anhydrous ammonia over a platinum catalyst at extreme temperatures. The resulting gases (nitric oxide and nitrogen dioxide) are cooled and demineralized into water. BNA is used for nitration of organics for production in plastics, surface coatings, dyes, pesticides, and explosives.

CARBON DIOXIDE LIQUID (CDL) – Carbon dioxide liquid is a colorless, odorless gas that is shipped under pressure as a liquid. This liquid absorbs readily into water to form carbonic acid, which is typically referred to as carbonated water.

DIESEL EXHAUST FLUiD (DEF) – DIesel exhaust fluid is a urea solution produced by combining pure liquid urea with clean plant stem condensate to produce a desired concentration. DEF is marketed as an ultra clean liquid fuel for catalytic abatement of nitrogen oxide emissions.

MIXED ACID – Mixed acid is a blend of strong nitric acid (98%) and oleum (sulfuric acid saturated with sulfur trioxide). Mixed acid is designed as a nitrating agent for industrial processes. Mixed acid reacts violently with oxidizable organic substances, to the point that ignition can occur. Mixed acid is used in the nitration of organics, as well as for production in plastics, surface coatings, dyes, pesticides, and explosives.

REFRIGERATION AMMONIA – Refrigeration ammonia is a colorless, odorless gas that is shipped under pressure as a liquid. Refrigeration ammonia has a pungent odor that is irritating to the mucosal membranes of the eyes and lungs. Contact with refrigeration ammonia liquid can cause frostbite. Refrigeration ammonia absorbs readily into water to form alkaline ammonium hydroxide solution, which is used as a refrigerant. Refrigeration ammonia can be easily compressed into a liquid, and back into a gas. Refrigeration ammonia is corrosive to aluminum, tin, copper, lead, silver, zinc, and their alloys.
UREA AMMONIUM NITRATE (UAN) – Urea ammonium nitrate is a solution created by dissolving amide nitrate salt in water. UAE produces a slight ammonia odor. It is predominantly used in fertilizer solution.

UREA FEED GRADE (UFG) – Urea feed grade is a small spherical white solid that is easily decomposed to ammonia and carbon dioxide by heating, and is soluble in water. UFG is added to cattle feed to boost protein content. UFG may also be used as a slow release fertilizer.
UREA PRILL – Urea prill is a small, spherical white solid that is soluble in water. It is suitable for use as an agricultural and forestry fertilizer, as well as having other industrial applications which require a high quality nitrogen source.

UREA SOLUTION – Urea solution is a dissolution of pure amide directly into clear condensate so no ions of any metals are present. Urea solution is marketed as an ultra clean liquid fuel for catalytic abatement of nitrogen oxide emissions.

ANFO, Boosters & Fuel Systems Storage for ATF, OHSA or DoD Compliance

ANFO Storage Magazines are approved for the storage of a variety of materials to stay in compliance with Safety & Environmental regulations and rule. More details & Pricing at http://www.klsecurity.com/products/safety-compliance/atf-approved-storage.html

Whether your operation us utilizing bulk or packaged Ammonium Nitrate, ANFO, Emulsions, ANFO/Emulsion Blends or other agents for mining, construction or quarry operations, we have a Storage Magazine (indoor and outdoor certified) to ensure you stay in compliance with ATF, OHSA or DOD safety standards.

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.

anfo-storage-magazine — 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.

A prime example of a compliant Type 2 storage magazine is the Securall M200 Explosive Storage Magazine.

Type 3 Storage Magazines

Type 3 magazine storage containers are commonly known in layman’s terms as “Day Boxes.” These magazines are utilized mainly in the transportation of high and low explosives to sites in the field, and are to mean to be attended at all times. Per the ATF, “Explosive materials are not to be left unattended in type 3 magazines and must be removed to type 1 or 2 magazines for unattended magazines.

Magazines meeting the criteria for Type 3 classification must be easily portable. Type 3 magazines can be mounted to a vehicle or trailer, or can be left free standing to be carried by hand. A textbook example of the Type 3 storage magazines it the Securall Type 3 Daybox. Features of the Day Box include;

12 gauge steel
Interior lined with ½” plywood
all spark producing material covered or sealed
padlock hasps welded, riveted, or bolted with nuts on the inside
finish of 2 part chemical resistant aliphatic polyurethane

Type 4 Storage Magazines

Type 2 storage magazines are designed for the storage of low or high explosives. These magazines are made of steel, and are weather, fire, and theft resistant. Like its type 2 counterparts, a type 4 magazine is made for indoor, outdoor, portable, or mobile use. However, a type 4 magazine can also be used in a permanent location.

An example of an exemplary Type 4 storage magazine is the Securall M400 Explosive Storage Magazine. This magazine comes equipped with many features, including;

12 gauge formed outer wall
interior lined with ½” plywood sheets
2 hooded hasps for padlocks placed on door to prevent tampering or forced entry
Lift lugs

Larger units of type 4 storage magazines are manufactured with I Beam supports running the length of the structure, and the magazines can be drug along surfaces by the end of the I Beams. These magazines can also be equipped with fork channels and casters to make relocation even more simple.

It should also be noted that 1.3G display fireworks (formerly Class B fireworks) that are for aerial display are to be stored in approved storage magazines. Whether these are for pyrotechnics storage or ATF 54 licensed persons requiring day boxes, our full line of fireworks storage containers and solutions are designed to meet your price point and budget.
