Canadian Type 4 vs. U.S. Type 2 Magazines Adapted from Information by the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosives TheATF (Bureau of Alcohol, Tobacco, Firearms, and Explosives) has received a lot of questions regarding the use of Canadian type 4 magazines to store high explosives in the U.S. Here are some of the differences between the construction requirements in Canada and the 27 CFR 555.208(a) construction standards of type 2 maga- zines in the U.S. Several aspects of Canadian type 4 magazines do not comply with the bullet resistance standards stated in Federal explosives regulations. According to 27 CFR 555.208(a), Outdoor magazines are to be bullet resistant, fire resistant, weather resistant, theft resistant and ventilated… The exterior and doors are to be constructed of not less than ¼-inch steel and lined with at least two inches of hardwood. Doors - The construction require- ments for doors on Canadian type 4 mag- azines require the laminated door be fabricated from two metal steel plates separated by a fire-resistant material, e.g., “backer board” made of bonded refined cement mixed with wood or fiberglass. The inner surface of the door must be lined with exterior fir plywood firmly fixed in place. Measurements of the steel plates or wood lining are not listed in the Canadian Storage Standards and can only be obtained on a need-to-know basis. Under ATF requirements, the door must be constructed of ¼-inch steel and lined with at least two inches of hardwood. Alternately, the door construction may also conform to the bullet-resistant stan- dards in ATF Ruling 76-18. Locks - Canadian type 4 door locks consist of a sliding lock bolt train which secures the door at three points along the door jamb coupled with rim or mortise- mounted cylinders and dead bolt-type locks. The locking dev i ces have a t least six pins and will include antidrill, pick-resistant, and bypass- res i s tant features. This lock- ing mechanism is considered a three po i n t l ock unde r ATF standards. Walls -According t o t he Canad i an Storage Standards for Industrial Explosives, the exterior walls must be fab- ricated with continuous- l y we l d e d seams from roughly ¼-inch or more metal plate, the inner walls fully sheathed with ¾- inch plywood, and the wal ls must be f i l led wi th bul let - resistant material. The bullet-resistant material between the exterior and interior wall is either three inches of washed hard crushed stone or washed coarse gravel, or roughly six inches of sand as a substi- tute bullet-resistant material. ATF Ruling 76-18 item (q) permits an exterior constructed of any type of fire- resistant material which is structurally sound, lined with an intermediate six-inch space filled with well-tamped dry sand or well-tamped sand/cement mixture. De- pending on the wall construction of the specific magazine, a variance may be required to use the magazine in the U.S. Roof - The Canadian type 4 roof is fabricated from roughly ¼-inch or heav- ier metal plate. The metal plate roof does not provide equivalent bullet resistance to a roof constructed of ¼-inch steel lined with two inches of hardwood as required for U.S. type 2 magazines. Therefore, it is generally not adequate to meet U.S. type 2 standards. However, the Canadian type 4 mag- azine is equivalent to the fabricated metal and iron/aluminum roof construction requirements for U.S. type 1 magazines. The roof may be used if placed in an area where an individual could not fire a bullet through the magazine roof and into the explosives within. However, a variance is still required to use the Canadian standard roof because this provision is not specified in the regulations for type 2 magazines. As you can see, there may be some areas of overlap between the Canadian Storage Standards and ATF’s regulations. However, to use a Canadian type 4 mag- azine as a U.S. type 2 magazine, several variances may be required. Remember, the responsible person on the Federal explosives license or permit must submit the variance request. ~ The Centerline 7 1/2” x 10” hydraulic drive mono mud pump ~ ~ compact ~ fits on top or under deck ~ pumps the rated flow of a 5” x 6” @ over twice the rated pressure ~ weighs 650 lbs, 1615 lbs less!
