In which type of building can an ordinary safety fuse be safely stored?

• A. A garage subject to temperature extremes
• B. A secure and dry building
• C. Any open area
• D. A blasting explosives magazine only

Answer: (B)

An ordinary safety fuse should be stored in a secure and dry building to ensure its safety and effectiveness. The key factors in this choice involve shielding the fuse from environmental elements that could compromise its integrity. A dry environment prevents moisture from affecting the fuse, which could lead to malfunction or failure when the fuse is needed.

Additionally, secure storage minimizes the risk of unauthorized access or accidental damage, which is critical when dealing with explosive materials. Other locations, such as a garage subject to temperature extremes, could expose the fuse to conditions that might lead to degradation. An open area does not provide the necessary protection from environmental hazards or tampering. Finally, while a blasting explosives magazine is meant for explosives, it is not the safest or most suitable place for ordinary safety fuses, as each type of explosive material has specific storage requirements based on its characteristics.

Thus, a secure and dry building is the most appropriate choice for the safe storage of an ordinary safety fuse.
