NAR SAFETY RULES
National Association of Rocketry Safety Code
- 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.
- Motors / Engines — I will use only commercial made NAR certified model rocket engines in the manner recommended by the manufacturer. I will not alter the model rocket engine, its parts, or its ingredients.
- Recovery — I will always use a recovery system in my model rocket that will return it safely to the ground so it may be flown again. I will use only flame resistant recovery wadding if required.
- Weight and Power Limits — My model rocket will weigh no more that 1,500 grams (53 oz) at lift-off, and its rocket engines will produce no more than 320 Newton-seconds (4.45 Newtons equals 1.0 pound) of total impulse. My model rocket will weight no more than the engine manufacturer’s recommended maximum lift-off weight for the engine used, or I will use an engine recommended by the manufacture for my model rocket.
- Stability — I will check the stability of my model rocket before its first flight, except when launching a model rocket of already proven stability.
- Payloads — Except for insects, my model rocket will never carry live animals or a payload that’s intended to be flammable, explosive, or harmful.
- Launch site — I will launch my model rocket outdoors in a cleared area, free of tall trees, power lines, buildings, and dry brush and grass. My launch site will be at least as large as that recommend in the following table:
|Total Impulse (Newton•seconds)
|Equivalent Engine Classification
|Site Dimension (Minimums)
|¼A & ½A
- Launcher — I will launch my model rocket from a stable launching device that provides rigid guidance until the model rocket has reached a speed adequate to ensure a safe flight. To prevent accidental eye injury, I will always place the launcher so that the end of the rod is above eye level or I will cap the end of the launch 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 engine exhaust from hitting the ground directly. I will always clear the area around my launch device of brown grass, dry weeds and other east-to-burn materials.
- Ignition System — The system I use to launch my model rocket will be remote controlled and electronically 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 15 feet (5 meters) from the model rocket when I am igniting model rocket engines totaling 30 Newton-seconds or less of total impulse and at least 30 feet (8 meters) from the model rocket when I am igniting model rocket engines totaling more than 30 Newton seconds of total impels. I will use only electrical Igniters recommended by the engine manufacturer that will ignite model rocket engines within one second of actuation of the launching switch.
- 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 liftoff before I begin my audible five second countdown. I will not launch a model rocket using it as a weapon. 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.
- Flying conditions — I will launch my model rocket only when the wind is less than 20 miles (30 kilometers) an hour. I will not launch my model rocket so it flies into clouds, near aircraft in flight, or in a manner that is hazardous to people or property.
- Pre-Launch Test — When conducting research activities with unproved 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 unproved design in complete isolation from persons not participating in the actual launching.
- Launch Angle — My launch device will be pointed within 30 degrees of vertical. I will never use model rocket engines to propel any device horizontally.
- Recovery Hazards — If a model rocket becomes entangled in a power line or other dangerous place, I will not attempt to retrieve it.
