California Blasters Practice Test

A first class magazine is required based on the quantity of explosives you’re storing. The rule is that you need first class storage whenever the amount exceeds 100 pounds. This threshold exists because larger quantities demand higher security and stricter safety measures to prevent accidents or theft. So storing more than 100 pounds triggers the need for a first class magazine, while storing 100 pounds or less does not. The other options don’t fit because they either set a higher or lower boundary or imply the requirement applies to any amount.
