What is the minimum safe distance when using a non-complex H, I, or J motor?

The minimum safe distance when using a non-complex H, I, or J motor is established at 100 feet (30 meters). This distance is determined based on the amount of energy and potential hazard posed by these types of motors during launch.

Non-complex H, I, or J motors can produce significant amounts of thrust and have the capability to propel rockets to substantial altitudes. The safe distance takes into account the risks of possible accidents, including ejection of debris, rocket failure, or an uncontrolled flight path, all of which can be dangerous to spectators and crew. The specified range allows for considerable safety margins to protect individuals in the vicinity.

In practice, this standard aligns with recommendations from rocketry organizations and ensures that bystanders are well outside the area of potential danger while still allowing for optimal observation of the launch. Adhering to this guideline helps ensure that all aspects of safety are considered, thereby promoting responsible rocketry practices.
