The minimum safe distance required when launching a non-complex H, I, or J motor is 100 ft (30m). This distance is established to ensure adequate safety margins for bystanders and participants during a rocket launch. Launching rockets can involve significant forces and potential hazards, including the risk of accidental ignition or ejection of debris, which can pose risks to people nearby.

The specified distance facilitates a buffer zone that minimizes exposure to any potential hazards associated with rocket propulsion, such as shock waves, noise, and the possibility of the rocket failing to function as intended. Establishing this minimum distance is consistent with safety guidelines and recommendations provided by rocket launching organizations and safety standards in model rocketry.

In contrast, lesser distances may not adequately protect against these hazards, as evidenced by the increased risks associated with launching more powerful or complex motors, where far greater distances are typically required. Therefore, maintaining the 100 ft (30m) distance is crucial for ensuring safety during the operation of rockets using H, I, or J motors.
