How long are approved deviations considered valid?

The duration of validity for approved deviations being one year is established to ensure that any changes made to standard operating procedures or safety protocols are periodically reviewed. This requirement encourages ongoing assessment of the deviation's effectiveness and relevance in relation to current safety standards, operational needs, and environmental conditions. Allowing a one-year period enables supervisors and safety officers to reevaluate the deviations in light of any new data, lessons learned, or advancements in safety practices, thus maintaining high safety and operational standards over time. This periodic review is crucial for maintaining situational awareness and fostering a culture of safety within the Marine Corps.
