Model Rocket Safety Guide
Model rockets are very safe if you follow the appropriate precautions. This is the Official Model Rocket Safety Code of the National Association of Rocketry.
I will use only lightweight, non-metal parts for the nose, body, and
fins of my rocket.
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.
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 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 at least 15 feet away when
I launch rockets with D motors or smaller, and 30 feet 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
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 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
My model rocket will not weigh more than 1,500 grams (53 ounces) at
liftoff and will not contain more than 125 grams (4.4 ounces) of
propellant or 320 N-sec (71.9 pound-seconds) of total impulse. If my
model rocket weighs more than one pound (453 grams) at liftoff or has
more than four ounces (113 grams) of propellant, I will check and
comply with Federal Aviation Administration regulations before flying.
- 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
- Launch Site.
I will launch my rocket outdoors, in an open area at least as large as
shown in Table 1 below, and in
safe weather conditions with wind speeds no greater than 20 miles 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 system
wadding in my rocket.
- Recovery Safety.
I will not attempt to recover my rocket from power lines, tall trees,
or other dangerous places.
