Storage Type III features which elements?

• A. A day box with metallic exterior, non-sparking interior, hasp, padlock
• B. A relocatable steel box with hardwood lining
• C. A locked container with kingpin lock
• D. A wooden cabinet with no lock

Answer: (A)

Storage Type III is defined by a portable, secure day-use box that minimizes ignition risk on the job site. The best choice describes a metal exterior and a non-sparking interior, which helps prevent sparks if tools or materials strike the walls. The inclusion of a hasp and a padlock provides the necessary security to restrict access when the box isn’t being actively used, aligning with the safety requirements for temporary on-site storage of blasting materials. The other options depict storage configurations that either lack the spark-resistant interior, rely on different locking or enclosure designs, or are simply not secure enough for blasting materials, so they don’t fit the typical Type III setup.
