The Ten Standard Firefighting Orders are a set of systematically organized rules designed by a USDA Forest Service task force to reduce danger to personnel and increase fire fighting efficiency. The rules were based upon the success of the United States Armed Forces' General Orders for Sentries, a set of guidelines designed for safety and efficiency for military personnel standing sentry duty. The Ten Standard Orders were later supplemented by 18 Situations That Shout Watch Out, or the 18 Watchout Situations. While the original orders were designed to be implemented in an order of importance, the order was changed in the 1980s to remove this priority of orders and create an easy to remember list with each order beginning with an initial of "Fire Orders", then returned to the original order
