Which statement best defines a Type 3 magazine?

• A. Portable outdoor magazine for temporary storage of high explosive materials while attended
• B. Large indoor storage facility
• C. Magazine used for storing blasting caps only
• D. Permanent outdoor storage yard

Answer: (A)

The statement being tested is how a Type 3 magazine is defined in explosives storage. A Type 3 magazine is a portable outdoor container used for the temporary storage of high explosive materials while someone is present. This means it’s designed to be moved to the job site and kept outside, but only used when a person is on site to supervise and secure it. It’s not meant for long-term or permanent storage, and it isn’t limited to storing only detonators or blasting caps, which are covered by different classifications.

Think about the purpose: you bring explosives to the site for a blast, you store them in a portable outdoor magazine so they’re readily accessible during the work, and you maintain attendance to ensure security and safety. The other options describe conditions that don’t fit that use—indoor or permanent outdoor facilities are for long-term storage, and a magazine for blasting caps only is a different category entirely.
