Be Unsafe, But Just This Once

Karen Rutzick's story yesterday on emerging details about the National Security Personnel System included the following statement from a sample set of job objectives for a health and safety worker:

One failure to report unsafe acts or conditions or comply with safety rules and regulations during rating period is allowed.

I admire the level of specificity they're going for here, but doesn't this mean that such workers could be safe all year, then use their get out of jail free card to ignore safety rules one time before the rating period is up? Is that what the Pentagon really wants?
