Model rocket safety code
1 Materials. My model rocket will be made of balsa, wood, paper or plastics or a combination of those materials, but contains no metal as structural parts.
2 Motors. I will use only certified, commercially made model rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer.


3 Ignition system. I will launch my rockets with an electrical launch system and electrical motor igniters. My launch system will have a safety interlock in series with the launch switch, and will use a launch switch that returns to the “off” position when released.


4 Misfires. If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher`s safety interlock or disconnect its battery, and wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket.


5 Launch safety. I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 5 meters away when I launch rockets with D motors or smaller, and 10 meters when I launch larger rockets. If I am uncertain about the safety or stability of an untested rocket, I will check the stability before flight and will fly it only after warning spectators and clearing them away to a safe distance.


6 Launcher. I will launch my rocket from a launch rod, tower, or rail that is pointed to within 30 degrees of the vertical to ensure that the rocket flies nearly straight up, and I will use a blast deflector to prevent the motors exhaust from hitting the ground. To prevent accidental eye injury, I will place launchers so that the end of the launch rod is above eye level or will cap the end of the rod when it is not in use.


7 Size. My model rocket will not weight more than 1,500 grams at lift off and will not contain more than 125 grams of propellant or 320 n-sec of total impulse. If my model rocket weights more than 500 grams at lift off or produces more than 20 n-sec of total impulse or contains more the 25grams propellant I will check and comply with Civil Aviation Safety Regulations (CASR) before flying.


8 Flight safety. I will not launch my rocket at targets, into clouds, or in a manner that is hazardous to persons or property, or near airplanes, or in the approach or departure paths of aerodromes or airports, and will not put any flammable or explosive payload in my rocket. WARNING Large fines apply by CASA for non-compliance.


9 Launch site. I will launch my rocket outdoors, in an open area at least as large as shown in the accompanying table, and in safe weather conditions with wind speeds no greater than 32 kilometers per hour. I will ensure that there is no dry grass close to the launch pad, and that the launch site does not present risk of grass fires.


10 recovery system. I will use a recovery system such as a streamer or parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery system wadding in my rocket.


11 Recovery safety. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places.
