> The following is a condensed version of 

the NAR/TRA HIGH POWER SAFETY CODE. The complete code can be found in the handbooks of the organizations.  1. Only a 
person who is a certified flyer shall operate or fly a high power rocket.  2. Must comply with United States Code 1348, "Airspace 
Control and Facilities", Federal Aviation Act of 1958 and other applicable federal, state, and local laws, rules, regulations, statutes, and 
ordinances.  3. A person shall fly a high power rocket only if it has been inspected and approved for flight by a Safety Monitor for 
compliance with the applicable provisions of this code.       4. Motors.  4.1 Use only certified commercially made rocket motors. 4.2 Do 
not dismantle, reload, or alter a disposable or expendable high power rocket motor, not alter the components of a reloadable high power 
rocket motor or use the contents of a reloadable rocket motor reloading kit for a purpose other than that specified by the manufacture in 
the rocket motor or reloading kit instructions.   5. A high power rocket shall be constructed to withstand the operating stresses and retain 
structural integrity under conditions expected or known to be encountered in flight.    6. A high power rocket vehicle intended to be 
propelled by one or more high power solid propellant rocket motor(s) shall be constructed using lightweight materials such as paper, 
wood, plastic, fiberglass, or, when necessary, ductile metal so that the rocket conforms to the other requirements of this code.    7. A 
person intending to operate a high power rocket shall determine its stability before flight, providing documentation of the location of the 
center of pressure and center of gravity of the high power rocket to the Safety Monitor, if requested.  8. Weight and Power Limits..   8.1 
Ensure that the rocket weighs less than the rocket motor manufacturer's recommended maximum liftoff weight for the rocket motor(s) 
used for the flight. During pre-flight inspection, The Safety Monitor may request documentary proof of compliance.   8.2 Do not install a 
rocket motor or combination of rocket motors that will produce more than 40,960 newton-seconds of total impulse (4.448 newtons 
equals 1.0 pound).        9. Recovery.     9.1 Fly a high power rocket only if it contains a recovery system that will return all parts of it 
safely to the ground so that it may be flown again.    9.2 Install only flame resistant recovery wadding if wadding is required by the 
design of the rocket.  9.3 Do not attempt to catch a high power rocket as it approaches the ground. 9.4 Do not attempt to retrieve a high 
power rocket from a place that is hazardous to people.   10. Payloads.   10.1 Do not install or incorporate in a high power rocket a 
payload that is intended to be flammable, explosive, or cause harm. 10.2 Do not fly a vertebrate animal in a high power rocker.  11. 
Launching Devices    11.1 Launch from a stable device that provides rigid guidance until the rocket has reached a speed adequate to 
ensure a safe flight path. 11.2 Incorporate a jet deflector device if necessary to prevent the rocket motor exhaust from impinging directly 
on flammable materials.  11.3 A launching device shall not be capable of launching a rocket at an angle more than 20 degrees from 
vertical.  11.4 Place the end of the launch rod or rail above eye level or cap it to prevent accidental eye injury. Store the launch rod or rail 
so it is capped, cased, or left in a condition where it cannot cause injury.      12. Ignition Systems.    12.1 Use an ignition system that is 
remotely controlled, electrically operated, and contains a launching switch that will return to "off" when released.     12.2 The ignition 
system shall contain a removable safety interlock device in series with the launch switch.   12.3 The launch system and igniter 
combination shall be designed, installed, and operated so the liftoff of the rocket shall occur within three (3) seconds of actuation of the 
launch system. If the rocket is propelled by a cluster of rocket motors designed to be ignited simultaneously, install an ignition scheme 
that has either been previously tested or has a demonstrated capability of igniting all rocket motors intended for launch ignition within 
one second following ignition system activation.  12.4 Install an ignition device in a high power rocket motor only at the launch site and 
at the last practical moment before the rocket is placed on the launcher.   13. Launch Site.    13.1 Launch a high power rocket only in an 
outdoor area where tall trees, power lines, and buildings will not present a hazard to the safe flight operation of a high power rocket in 
the opinion of the Safety Monitor. 13.2 Do not locate a launcher closer to the edge of the flying field (launch site) than one-half the 
radius of the minimum launch site dimension stated in Table 1.  13.3 The flying field (launch site) shall be at least as large for a given 
impulse as stated  Table 1 of the Tripoli safety code. See www.tripoli.org <

http://www.tripoli.org/

> .  14. Launcher Location    14.1 

Locate the launcher more than 1,500 feet from any occupied building. 14.2 Ensure that the ground for a radius of 10 feet around the 
launcher is clear of brown grass, dry weeds, or other easy-to-burn materials that could be ignited during launch by the exhaust of the 
rocket motor.    15. Safe Distances    15.1 No person shall be closer to the launch of a high power rocket than the person actually 
launching the rocket and those authorized by the Safety Monitor.  15.2 All spectators shall remain within an area determined by the 
Safety Monitor and behind the Safety Monitor and the person launching the rocket.  15.3 A person shall not be closer to the launch of a 
high power rocket than the applicable minimum safe distance set forth in Table 2 of the Tripoli Safety code. See www.tripoli.org

http://www.tripoli.org/

> .  16. Launch Operations.    16.1 Do not ignite and launch a high power rocket horizontally, at a target, or so 

the rocket's flight path goes into clouds or beyond the boundaries of the flying field (launch site).  16.2 Do not launch a high power 
rocket if the surface wind at the launcher is more than twenty (20) miles per hour.  16.3 Do not operate a high power rocket in a manner 
that is hazardous to aircraft.  17. Launch Control.    17.1 Launch a high power rocket only with the immediate knowledge, permission, 
and attention of the Safety Monitor.  17.2 All persons in the launching, spectator, and parking areas during a countdown and launch shall 
be standing and facing the launcher if requested to do so by the Safety Monitor.  17.3 Precede the launch with a five (5) second 
countdown audible throughout the launching, spectator, and parking areas. This countdown is given by the person launching the rocket, 
the Safety Monitor, or other flying site operating personnel.   17.4 Do not approach a high power rocket that has misfired until the safety 
inter-lock has been removed or the battery has been disconnected from the ignition system, one minute has passed, and the Safety 
Monitor has given permission for only a single person to approach the misfired rocket to inspect it.   I understand and will at all times 
conduct myself with the understanding that the above stated risks and safety procedures;  (a) are not necessarily all of the risks.   (b) that 
even by observing the above procedures there remain RISKS OF INJURY OR DEATH from HIGH POWER ROCKETRY.  (c) that the 
utmost in attention and prudence must be exercised at all times.  By purchasing this product(s) from Giant Leap Rocketry, Inc., you 
agree to: (1) Assume all of the risks, damages, injury, or even death.  (2) Assume the obligation to exercise the utmost care in pursuit of 
my activities at this event. (3) that you must be over 18 years old (for motor purchase and use).   Giant Leap Rocketry cannot be held 
responsible for the failure of participants to abide by safety codes, rules, regulations, etc. By using the products, you agree to abide by
