CES Storage & Transportation of Explosives 1 — Questions and Answers
Question 1: What is the primary factor used in ATF Quantity-Distance (Q-D) tables to determine required separation distances between explosive magazines and protected structures?
- The type of magazine construction
- The quantity of explosive stored (Correct answer)
- The age of the magazine
- The geographic location of the site
Correct answer: The quantity of explosive stored
Q-D tables use the net explosive weight (quantity) stored to calculate minimum separation distances from inhabited buildings and other protected structures.
Question 2: Which federal agency requires all licensed explosives dealers, manufacturers, and importers to maintain records of explosive transactions under the Safe Explosives Act?
- OSHA
- EPA
- ATF (Correct answer)
- DOT
Correct answer: ATF
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) administers the Safe Explosives Act and requires licensed handlers to keep transaction records for regulatory oversight.
Question 3: Under ATF regulations (27 CFR Part 555), how frequently must magazines storing explosive materials be inspected?
- Daily
- Every 3 days
- Every 7 days (Correct answer)
- Monthly
Correct answer: Every 7 days
ATF regulations require magazine inspections at least every 7 days to verify security, inventory accuracy, and proper storage conditions.
Question 4: Which ATF magazine type is designed for permanent above-ground storage and approved for the largest quantities of high explosives?
- Type I (Correct answer)
- Type III
- Type IV
- Type V
Correct answer: Type I
Type I magazines are heavy-duty, permanently constructed above-ground facilities that meet the highest ATF construction and security standards for storing large quantities of high explosives.
Question 5: Why must detonators (blasting caps) be stored separately from bulk explosive materials in magazines?
- They are more expensive and require special climate control
- Their accidental initiation could cause sympathetic detonation of adjacent bulk explosives (Correct answer)
- They degrade faster when exposed to other explosive chemicals
- ATF regulations require alphabetical separation of explosive types
Correct answer: Their accidental initiation could cause sympathetic detonation of adjacent bulk explosives
Storing detonators separately prevents an accidental cap detonation from triggering a mass detonation of bulk explosives, dramatically reducing the potential consequences of any storage incident.
Question 6: What DOT hazard class number is assigned to all explosive materials for transportation purposes?
- Class 3
- Class 5
- Class 1 (Correct answer)
- Class 8
Correct answer: Class 1
DOT classifies explosive materials under Hazard Class 1, subdivided into Divisions 1.1 through 1.6 based on the specific explosion hazard type.
Question 7: Which DOT division designation applies to explosives that present a mass explosion hazard, such as dynamite and bulk ANFO?
- Division 1.3
- Division 1.4
- Division 1.1 (Correct answer)
- Division 1.6
Correct answer: Division 1.1
Division 1.1 covers explosives with a mass explosion hazard, meaning detonation of one package can cause near-simultaneous detonation of the entire load, and includes materials like dynamite, TNT, and ANFO.
