Model Rocketry Safety Code chnages over time
shockwaveriderz
Section #2-Motors from 90/91/92/93/94 so I can see if and when it changes....
TIA

The NAR model rocket safety code was recently (2001?) revised to shorten and
simplidy it. It went from 14 rules to 11 rules.
The new 11 rule version is on the NAR web site. You can find the old one in
several of the PDF documents on the esteseducator.com website.

MODEL ROCKET SAFETY CODE
1. CONSTRUCTION. My model rockets will be made of lightweight
materials such as paper, wood, rubber and plastic, without any metal as
structural parts.
2. MOTORS. I will use only pre-loaded factory made NAR safety
certified model rocket motors in the manner recommended by the
manufacturer. I will not alter or dismantle model rocket motors or
their ingredients in any way or attempt to reload these motors.
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 motors will contain a total of no more
than 125 grams (4.4 ounces) of propellant. My model rockets will weight
no more than the motor manufacturer's recommended maximum liftoff weight
for the motors used.
5. STABILITY. I will check the stability of my model rockets before
their first flight, except when launching rockets of already proven
stability.
6. PAYLOADS. My model rockets will never carry live animals or
payloads that are intended to be flammable or explosive.
7. LAUNCH AREA. I will launch my model rockets outdoors in a cleared
area, free of tall trees, power lines and buildings. I will always
clear the area around my launch device of brown grass, dry weeds and
other easy to burn materials.
8. LAUNCHER. I will launch my model rockets from a 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 launcher 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 disassemble my launch rod when not in use and will never
store it in an upright position. The launch device will have a jet
deflector to prevent the motor exhaust from hitting the ground directly.
9. IGNITION SYSTEM. The system I use to launch my model rockets will
be remotely controlled and electrically operated and will contain a
launching switch that will return to "off" when released. The system
will contain a removable safety interlock in series with this firing
switch. When launching, all persons will remain at least 15 feet from
any model rocket when igniting motors totaling 30 Newton-seconds of
total impulse or less and at least 30 feet when igniting motors totaling
more than 30 Newton-seconds total impulse. I will use only electrical
igniters which ignite my rocket motor 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 disconnected from the launcher. In the
event of a misfire, I will wait on minute before allowing anyone to
approach the launcher. I will ensure that people in the vicinity are
aware of the pending rocket launch and are in a position to see the
rocket's liftoff before I begin my audible 5-second countdown.
11. FLYING CONDITIONS. I will launch my model rocket only when the
wind is less than 20 miles per hour and under conditions where the model
rocket will not fly into clouds, fly near aircraft in flight, or be
hazardous to people or property.
12. PRE-LAUNCH TEST. When conducting research activities with unproven
designs or methods, I will, when possible determine their reliability
through pre-launch tests. I will conduct launchings of unproven designs
in complete isolation from persons not participating in the actual
launching.
13. LAUNCH ANGLE. I will not launch rockets so 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 motors 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.

Suggestion:
NAR should put every past OFFICIAL version of the NAR Safety Code on its
web site.

An interesting idea. When I started in the mid 60s, there were only 10
rules. IIRC it changed in the late 60s when it "Metrified", then in the 80s
when G motors and increased weight limits were added, and again last year
when it was "simplified". I may have missed one change, but that's only 4-5
versions in almost 40 years.

I seem to recall that in 1967-68 the Estes Catalog had an "Astron Safety Code"
that differed slightly from the NAR code as published in Stine's "Handbook" (1967 ??
edition)"... the main difference I remember is that the Estes code had the
precautions against eye injury from the launch rod, which did not appear in
the NAR code at that time.
Also I'm not sure if the code then specified "NAR Safety Certified"
motors, or merely "commercially manufactured model rocket engines"...
and one wasn't supposed to reload them. (When I first re-entered the
hobby in early 2000, and found out about the "RMS" motors, my first
reaction was to wonder if that was against the safety code.)
I don't think the "Handbook" made much about "Certification", though it
did provide a small list (about 1/2 page) of available engine types, and
provided contact addresses for a few manufacturers. (This was just before
Estes went to metric designations, so there were motors listed such as
B.8-4 instead of B6-4 or whatever.

What I'm _really_ curious about is the early HPR codes: the "Tripoli Safety
Code (1987)" mentioned in the introduction to the TRA printing of NFPA-1127;
pre-TRA codes from sites like Lucerne and Aeropac, etc..
