What type of facility is normally used to store class/division 1.3 and 1.4 munitions?

The storage of class/division 1.3 and 1.4 munitions is typically designated for facilities that prioritize safety and mitigate risks related to the handling of these types of explosives. Class 1.3 includes ammunition with a medium explosion hazard, while class 1.4 comprises items that pose minimal risk in case of accident, as they are considered to be relatively safe under normal storage conditions.

A clay-tile storage warehouse is designed specifically to provide the necessary protection and isolation from potential hazards associated with these types of munitions. Clay tiles often offer good thermal properties and can help to contain the effects of any accidental ignition or explosion, making them an appropriate choice for safely storing unstable munitions.

In contrast, an areal storage vault might be more suited for higher-risk munitions, and soil-covered bunkers, while excellent for shielding against blasts, may not be necessary for the lower-risk categorization of class 1.4. Containerized storage units, while practical for transport and temporary storage, usually do not provide the same level of permanent safety features as a dedicated warehouse designed for the specific types of explosives found in classes 1.3 and 1.4.
