Under ATF regulations, what is the minimum required thickness of steel for a Type 1 (permanent) aboveground magazine?
Answer: 1/4 inch
27 CFR 555 Subpart K specifies that Type 1 aboveground magazines must be constructed with at least 1/4-inch steel on the exterior.
The American Table of Distances (ATD) used for explosives storage is published by which organization?
Answer: Institute of Makers of Explosives (IME)
The IME publishes the American Table of Distances, which establishes the minimum required separation distances between explosive storage and inhabited buildings, highways, and other magazines.
Under 27 CFR 555, a Type 2 magazine (portable, aboveground) is limited to storing no more than how many pounds of high explosives?
Answer: 500 lbs
Type 2 portable aboveground magazines are limited to storing 500 lbs or less of high explosives under ATF regulations.
Which type of ATF-approved magazine may be used for temporary field storage of explosive materials at a blasting site?
Answer: Type 3 (portable, outdoor)
Type 3 magazines are portable outdoor magazines approved for temporary field storage at jobsites where blasting is ongoing.
NFPA 495 (Explosive Materials Code) addresses which aspect of magazine separation from each other?
Answer: Inter-magazine distances are based on quantity-distance tables to prevent sympathetic detonation
NFPA 495 uses quantity-distance (Q-D) tables to specify inter-magazine separation distances that reduce the risk of sympathetic detonation.
Which of the following is NOT a required feature of an ATF-compliant Type 1 permanent aboveground magazine?
Answer: A sprinkler system for fire suppression
Type 1 magazines require bullet-resistant construction, ventilation, and non-sparking floors, but sprinkler systems are not required and could be hazardous with certain explosives.
Detonators (blasting caps) must be stored separately from other explosive materials. What is the minimum separation distance required by ATF regulations between a detonator magazine and other explosive storage?
Answer: Distance is determined by the American Table of Distances for inter-magazine spacing
The inter-magazine distance between detonator and explosive storage is governed by the ATD quantity-distance tables, not a fixed 50-foot rule.
