Model Rocket Safety Code

1. MATERIALS. My model rocket will be made of lightweight materials such as paper,wood, rubber, and plastic suitable for the power used and the performance of my model rocket. I will not use any metal for the nose cone, body or fins of a model rocket.


2. MOTORS. I will only use commercially-made certified model rocket motors in themanner recommended by the manufacturer. I will not alter the model rocket motor (engine), its parts, or its ingredients in any way.


3. RECOVERY. I will always use a recovery system in my model rocket that will return itsafely to the ground so it may be flown again. I will only use flame resistant recovery wadding if wadding is required by the design of my model rocket.


4. WEIGHT AND POWER LIMITS. My model rocket will weigh no more than 1500 grams at lift-off and its rocket motors(s) will produce no more than 320 Newton-seconds of total impulse. My model rocket will weigh no more than the motor manufacturer's recommended maximum lift-off weight for the motors used, or I will use the motors recommended by the manufacturer for my model rocket.


5. STABILITY. I will check the stability of my model rocket before its first flight, exceptwhen launching a model rocket of already proven stability.


6. PAYLOADS. Except insects, my model rocket will never carry live animals or a payloadthat is intended to be combustible, explosive, or harmful.


7. LAUNCH SITE. I will launch my model rocket outdoors in a cleared area, free of talltrees, power lines, buildings, and dry brush and grass. My launch site will be at least as large as that recommended in the Launch Site Dimensions table.



Installed Total Impulse (N-sec) Equivalent Motor Type Minimum Site Dimensions (Metre)
0.00--1.25 1/4A, 1/2A 15
1.26--2.50 A 30
2.51--5.00 B 60
5.01--10.00 C 120
10.01--20.00 D 150
20.01--40.00 E 300
40.01--80.00 F 300
80.01--160.00 G 300
160.01--320.00 Two Gs 460

8. LAUNCHER. I will launch my model rocket from a stable launch device that providesrigid guidance until the model rocket has reached a speed adequate to ensure a safe flight path. To prevent accidental eye injury, I will always place the launcher so the end of the rod is above eye level or I will cap the end of the rod when approaching it. I will cap or disassemble my launch rod when not in use and I will never store it in an upright position. My launcher will have a jet deflector device to prevent the motor exhaust from hitting the ground directly. I 
will always clear the area around my launch device of brown grass, dry weeds, or othereasy-to-burn materials.  

9. IGNITION SYSTEMS. The system I use to launch my model rocket will be remotelycontrolled and electrically operated. It will contain a launching switch that will return to "off" when released. The system will contain a removable safety interlock in series with the launch switch. All persons will remain at least 5 metres from the model rocket when I am igniting model rocket motors totalling 30 Newton-seconds or less of total impulse and at least 9 metres from the model rocket when I am igniting model rocket motors totalling more than 30 Newton-seconds of total impulse. I will use only electrical igniters recommended by the motor manufacturer that will ignite model rocket motor(s) within one second of actuation of the launching system. 

10. LAUNCH SAFETY. I will ensure that people in the launch area are aware of the pending model rocket launch and can see the model rocket's lift-off before I begin my audible five-second countdown. I will not launch a model rocket so its flight path will carry it against a target. If my model rocket suffers a misfire, I will not allow anyone to approach it or the launcher until I have made certain that the safety interlock has been removed or that the battery has been disconnected from the ignition system. I will wait one minute after a misfire before allowing anyone to approach the launcher.  

11. FLYING CONDITIONS. I will launch my model rocket only when the wind is no morethan 32 kilometres per hour. I will not launch my model rocket so it flies near aircraft in flight, or in a manner that is hazardous to people or property.  

12. PRE-LAUNCH TEST. When conducting research activities with unproven model rocket designs or methods I will, when possible, determine the reliability of my model rocket by pre-launch tests. I will conduct the launching of an unproven design in complete isolation from persons not participating in the actual launching.  

13. LAUNCH ANGLE. My launch device will be pointed within 30 degrees of vertical. I will never use model rocket motors to propel any device horizontally.  


14. RECOVERY HAZARDS. If a model rocket becomes entangled in a power line or otherdangerous place, I will not attempt to retrieve it.
