MODEL ROCKETRY
SAFETY CODE
1. CONSTRUCTION -My model rockets will
be made of lightweight materials such as paper,
wood, rubbe~ and plastic without any metal or
other hazardous material as structu ral parts.
2. ENGINES - I will use only pre-loaded
factory-made NAR certified rocket engines in the
manner recommended by the manufacture~ I will
not alter or dismantle model rocket engines Qr
their ingredients in any way, or attempt to reload
these engines.
3. RECOVERY~I will always use a recovery
system in my model rockets that will return them
safely to the ground so that they may be flown
again. I will use only flame resistant recovery
wadding in my rockets.
4. WEIGHT LIMITS - My model rockets will
weigh no more than 1500 grams (53 ounces) at
liftoff and the engines will contain a total of no
more than 125 grams (4.4 ounces) of propellant.
My model rockets will weigh less than the engine
manufacturers' recommended maximum liftoff
weight for the engines used, or I will use engines
recommended by the manufacturer for my ,
rockets.
5. STABILITY- I will check the stabilityof my
model rockets beforetheir first flight, except
when launching models of already proven
stability.
6. PAYLOADS- My model rockets will never
carry liveanimals,or payloads that are intended
to be flammableor explosive.
7. LAUNCH AREA - I will launch model
rockets outdoors in a cleared area, free of tall
trees, power lines, and buildings. I will ensure
that people in the launch area are aware of the
pending rocket launch and are in a position to
see the rocket's liftoff before I begin my audible
five-second count down.
.a...LAUNCHER - I will launch my model
rockets from a launch rod or other device which
provides rigid guidance until the rocket has
reached a speed adequate to ensure a safe flight
path. To prevent accidental eye injury, I will
always place the lau ncher so that the end of the
rod is above eye level or will cap the end of the
rod when approaching it. I will cap or disassem-
ble my launch rod when not in use and 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
easy-to-burn materials.
9. IGNITION SYSTEM - The system I use to
launch my model rockets will be remotely con-
trolled and electrically operated, and will contain
a launching switch that will return to "off" when
released. The system will contain a removeable
safety interlock in series with the launching
switch. All persons will remain at least 15 feet
from the model rocket when I am igniting
engines totalling 30 Newton-seconds or less of
total impulse and at least 30 feet from the model
rocket when I am igniting engines totalling more
than 30 Newton-seconds total impulse. I will use
only electrical igniters that will ignite my rocket
engine(s) within one second of actuation of the
launching switch.
10. LAUNCH SAFETY - I will not let anyone
approach a model rocket on a launcher until I
have made sure that the safety interlock has
been removed or the battery has been discon-
nected from the ignition system. In the event of a
misfire I will wait one minute before allowing
anyone to approach the launcher.
11. FLYING CONDllONS -I will launch my
model rocket only when the wind is less than 20
miles per hour and under conditions where the
model will not fly into clouds, fly near aircraft in
flight, or be hazardous to people or property.
12. PRE-LAUNCH TEST - When conducting
research activites with unproven designs or
methods, I will, when possible, determine their
reliability through pre-launch tests. I will conduct
launchings or unproven designs in complete
isolation from persons not participating in the
actual launching.
13. LAUNCH ANGLE - I will not launch model
rockets so that their flight path will carry them
against targets. My launch device will be pointed
within 30 degrees of vertical. I will never use
model rocket engines to propel any device
horizontally.
14. RECOVERY HAZARDS - If a model rocket
becomes entangled in a power line or other
dangerous place, I will not attempt to retrieve it.
