Question 2

What is the primary purpose of a 'day box' (field box) used at a blasting work site?

Accepted Answer

To temporarily hold small quantities of explosives needed for that day's operations

Answer

A day box is an approved portable storage container that holds the quantity of explosives needed for a single day's work at the blast site, reducing multiple trips to the main magazine.

Question 3

Which of the following is strictly prohibited in the vicinity of explosive magazines?

Accepted Answer

Combustible materials such as weeds and dry brush

Answer

ATF regulations require that combustible vegetation and debris be cleared from around magazines because fire spreading to the structure could cause a catastrophic explosion.

Question 4

When explosives and detonators must be transported in the same vehicle, what is the required arrangement per DOT regulations?

Accepted Answer

Detonators must be in a separate, secured compartment or a separate vehicle

Answer

DOT and ATF require that detonators be transported separately from other explosives—either in a divided vehicle with a proper barrier meeting specifications or in a completely separate vehicle—mirroring the magazine storage separation requirement.

What is the regulatory term for the minimum required distance between an explosive storage magazine and a protected structure such as an inhabited building?

Accepted Answer

Separation distance

Answer

'Separation distance' is the ATF and IME regulatory term for the minimum required spacing between an explosive storage facility and a protected structure, determined using Quantity-Distance tables.
