Confirm that explosive magazines comply with mandatory separation distances from inhabited structures, roads, and other magazines.

  • Has the separation distance from the magazine to inhabited structures been measured and verified to meet minimum requirements?
  • Is the measured distance from the magazine to the nearest public road compliant with ATF quantity-distance tables?
  • Is the magazine located at the minimum required distance from other explosive storage magazines?
  • Is the area surrounding the magazine clear of combustible debris, brush, and flammable materials within 25 feet?
  • Are barricades or earthen berms in place and in good condition to provide blast containment per quantity-distance requirements?

Inventory Control & Recordkeeping

Audit explosive inventory records, including receipts, usage logs, and balance on hand, to ensure accurate and up-to-date documentation.

  • Is a current explosive inventory log maintained and reconciled with the physical count on hand?
  • Does the physical count of explosives match the recorded inventory balance?
  • Are all explosive receipts and distribution records retained for the minimum required period of five years?
  • Are detonators stored separately from other explosives with proper segregation maintained?
  • Is the oldest stock being rotated to the front and used first (FIFO method) to prevent degradation?

Storage Conditions & Environmental Controls

Inspect the physical storage conditions inside the magazine including temperature, moisture, and organization of explosive products.

  • Is the interior temperature of the magazine within the manufacturer's recommended storage range?
  • Is the magazine interior free from moisture, water infiltration, and signs of dampness that could degrade explosives?
  • Are explosives stored on wooden shelving or dunnage at least 4 inches off the floor?
  • Are all explosive containers undamaged, properly labeled, and free from leaking or crystallization?
  • Is the magazine free from unauthorized items including tools, lubricants, flammable liquids, and personal items?

Access Control & Authorized Personnel

Verify that access to explosive magazines is restricted to trained, authorized personnel in accordance with MSHA and ATF requirements.

  • Is an up-to-date list of authorized personnel permitted to access the magazine maintained and posted?
  • Have all personnel with magazine access completed required explosives handling training per MSHA regulations?

  • Are smoking, open flames, and electronic devices prohibited within the magazine and posted exclusion zone?
  • Is a fire extinguisher of appropriate class and rating stationed within 50 feet of the magazine?

Emergency Procedures & Incident Preparedness

Confirm that emergency response plans, notification procedures, and misfired shot protocols are documented and current.

  • Is an emergency response plan specific to the magazine location available and current within the last 12 months?
  • Are procedures for handling misfired shots and degraded explosives documented and communicated to all blasting personnel?
  • Have all applicable personnel been briefed on emergency evacuation routes and assembly points for a magazine incident?
  • Is emergency contact information for local law enforcement, ATF, and MSHA posted visibly near the magazine?
  • Has a theft or loss reporting procedure been established and tested within the past year?

Audit Findings & Corrective Actions

Document any deficiencies identified during the audit, assign corrective actions, and capture photographic evidence.

  • Were any violations or non-conformances identified during this audit?
  • Please describe all identified deficiencies including location, severity, and applicable regulation reference?
  • Have corrective actions been assigned with responsible parties and target completion dates?
  • Are photographic records of the magazine condition and any deficiencies captured for this audit?
  • Has this completed audit been submitted to the Mine Safety Manager and retained in the compliance records?
