What is the First In First Out rule and why is it used for rations and parts?

• A. First-In, First-Out; ensures older stock is issued first to prevent spoilage or obsolescence
• B. Last-In, First-Out; ensures oldest stock is issued first
• C. First-Out, Last-In; ensures stock is rotated by batch
• D. FIFO is not used for rations and parts

Answer: (A)

First-In, First-Out means the oldest stock is issued first. This keeps items from expiring on the shelf and prevents waste. For rations, using the oldest stock first ensures food remains within its shelf life and is safe to eat. For parts, rotating by age helps prevent obsolete or degraded lots from being used later, keeping equipment reliable and reducing waste. FIFO matches how items actually age in storage and supports proper inventory control. The other ideas either reverse the order or aren’t standard practice, which could lead to expired rations or outdated parts being issued.
