Having your rocket land safely under parachute or streamer is paramount when you are shooting objects into the sky. Members are expected to learn the safety codes for both low and high power rockets. At the launch site the Range Safety Officer is responsible for ensuring that the safety codes are followed and checking that rockets are safe to fly.
Model Rocket Safety Code
Model rocketry is recommended for ages 8 and above, with adult supervision for those under age 14. This code applies to rockets using motors in the power ranges Micromaxx® to 2 Gs, but not to high power and experimental rockets.
- MATERIALS. I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket.
- 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.
- 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.
- 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 it’s battery, and will wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket.
- LAUNCH SAFETY. I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of 5 metres away when I launch rockets with D motors or smaller, and 10 metres away 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.
- LAUNCHER. I will launch my rocket form 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 motor’s 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.
- SIZE. My model rocket will not weigh more than 1,500 grammes at liftoff and will not contain more than 125 grammes of propellant nor produce more than 320 N-secs of total impulse.
- FLIGHT SAFETY. I will not launch my rocket at targets, into clouds, or near airplanes, and will not put any flammable or explosive payload in my rocket.
- LAUNCH SITE. I will launch my rocket outdoors, in an open area at least as large as shown in the table below, and in safe weather conditions with wind speeds no greater than 32 kilometres 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.
- 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 wadding in my rocket.
- RECOVERY SAFETY. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places. I promise to read and follow the Model Rocket Safety Code.
