What does the phrase "Keep your dime" refer to in fire operations?

The phrase "Keep your dime" in fire operations is a reminder for personnel to maintain a distance while operating hand tools. Specifically, it advises firefighters to stay at least 10 feet apart to ensure safety and prevent accidents. This practice is essential during fire operations, as working too closely can lead to increased risks, such as injuries from swinging tools or reduced situational awareness. Keeping this distance allows for effective communication and coordination among crew members while providing enough space to maneuver safely and effectively around potentially dangerous environments.
