How often must military munitions sites be inspected under the MMR?

The correct answer is based on the principle that the frequency of inspections for military munitions sites is primarily guided by a risk assessment process. This allows for a tailored approach, where sites assessed to have a higher risk may require more frequent inspections, while those with lower risk profiles may be inspected less often.

This risk-based methodology is critical to ensuring that inspections are efficient and effective, allocating resources toward areas that may pose a greater safety or environmental hazard. By using risk assessments, military operations can maintain appropriate oversight while ensuring compliance with safety regulations and environmental protection standards.

In contrast, predetermined frequencies such as annually, after every training exercise, or every five years lack the necessary flexibility that a risk assessment-based approach provides. This flexibility is essential for addressing the unique conditions and potential hazards present at different sites.
