Underground magazines shall not be located within how many meters from workplaces?

• A. 10
• B. 25
• C. 40
• D. 60

Answer: (B)

Keep in mind that underground magazines store blasting explosives, so a safety buffer between the storage and where workers are located is essential. A minimum distance of 25 meters from workplaces is required to limit the effects of a potential blast—reducing exposure to the blast wave, heat, and flying debris and allowing safer evacuation. Distances shorter than 25 meters would not meet safety standards, while larger separations would exceed the minimum but are not required by the regulation.
