Model Rocket and High Power Rocket Safety Codes
Vendor developed, consumer self-regulating guidelines that have worked for
over 55 years and 900,000,000 rocket launchings with almost no incidents.

2000 NAR Model Rocketry Safety Code
August 2012 update and beyond.
2000 NAR Model Rocketry Safety Code
  1. 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.
  2. Motors. I will use only commercially-made, NAR-certified model rocket motors in the manner recommended by the manufacturer. I will not alter the model rocket motor, its parts, or its ingredients in any way.
  3. 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 wadding is required by the design of my model rocket.
  4. Weight and Power Limits. My model rocket will weigh no more than 1,500 grams (53 ounces) at lift-off and its rocket motors will produce no more than 320 Newton-seconds (71.9 pound-seconds) of total impulse. My model rocket will weigh no more than the motor manufacturer's recommended maximum lift-off weight for the motors used, or I will use motors recommended by the manufacturer for my model rocket.
  5. Stability. I will check the stability of my model rocket before its first flight, except when launching a model rocket of already proven stability.
  6. Payloads. My model rocket will never carry live animals (except insects) or a payload that is intended to be flammable, explosive, or harmful.
  7. 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 area will be at least as large as that recommended in the accompanying table.
  8. Launcher. I will launch my model rocket from a stable launch device that provides rigid guidance until the model rocket has reached a speed adequate to ensure a safe flight path. To prevent accidental eye injury, I will always place the launcher so the end of the rod is above eye level or I will cap the end of the 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 motor exhaust from hitting the ground directly. I will always clear the area around my launch device of brown grass, dry weeds, or other easy-to-burn materials.
  9. Ignition System. The system I use to launch my model rocket will be remotely controlled and electrically 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 from the model rocket when I am igniting model rocket motors totalling 30 Newton-seconds or less of total impulse and at least 30 feet from the model rocket when I am igniting model rocket motors totalling more than 30 Newton-seconds of total impulse. I will use only electrical igniters recommended by the motor manufacturer that will ignite model rocket motors within one second of actuation of the launching switch.
  10. 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 lift-off before I begin my audible five-second countdown. I will not launch my model rocket so its flight path will carry it against a target. 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.
  11. Flying Conditions. I will launch my model rocket only when the wind is less than 20 miles per 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.
  12. Pre-Launch Test. When conducting research activities with unproven 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 unproven design in complete isolation from persons not participating in the actual launching.
  13. Launch Angle. 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.

2000 NAR High Power Rocketry Safety Code
August 2012 update and beyond.
2000 NAR High Power Rocketry Safety Code
  1. Certification. I will fly high power rockets only when certified to do so by the National Association of Rocketry.
  2. Operating Clearances. I will fly high power rockets only in compliance with Federal Aviation Regulations Part 101 (Section 307, 72 Statute 749, 49 United States Code 1348, "Airspace Control and Facilities," Federal Aviation Act of 1958) and all other federal, state, and local laws, rules, regulations, statutes, and ordinances.
  3. Materials. My high power rocket will be made of lightweight materials such as paper, wood, rubber, and plastic, or the minimum amount of ductile metal suitable for the power used and the performance of my rocket.
  4. Motors. I will use only commercially-made, NAR-certified rocket motors in the manner recommended by the manufacturer. I will not alter the rocket motor, its parts, or its ingredients in any way.
  5. Recovery. I will always use a recovery system in my high power rocket that will return it safely to the ground so it may be flown again. I will use only flame-resistant recovery wadding if wadding is required by the design of my rocket.
  6. Weight and Power Limits. My rocket will weigh no more than the motor manufacturer's recommended maximum liftoff weight for the motors used, or I will use motors recommended by the manufacturer of the rocket kit. My high power rocket will be propelled by rocket motors that produce no more than 40,960 Newton-seconds (9,204 pound-seconds) of total impulse.
  7. Stability. I will check the stability of my high power rocket before its first flight, except when launching a rocket of already proven stability.
  8. Payloads. My high power rocket will never carry live animals (except insects) or a payload that is intended to be flammable, explosive, or harmful.
  9. Launch Site. I will launch my high power rocket outdoors in a cleared area, free of tall trees, power lines, buildings, and dry brush and grass. My launcher will be located at least 1,500 feet from any occupied building. My launch site will have minimum dimensions at least as great as those in the Launch Site Dimension Table. As an alternative, the site's minimum dimension will be one-half the maximum altitude of any rocket being flown, or 1,500 feet, whichever is greater. My launcher will be no closer to the edge of the launch site than one-half of the minimum required launch site dimension.
  10. Launcher. I will launch my high power rocket from a stable launch device that 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 the end of the rod is above eye level or I will cap the end of the 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 motor exhaust from hitting the ground directly. I will always clear the area for a radius of ten feet around my launch device of brown grass, dry weeds, or other easy-to-burn materials.
  11. Ignition System. The system I use to launch my high power rocket will be remotely controlled and electrically 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 a distance from the high power rocket and launcher as determined by the total impulse of the installed rocket motor(s) according to the accompanying Safe Distance Table.
  12. Launch Safety. I will ensure that people in the launch area are aware of the pending high power rocket launch and can see the rocket's liftoff before I begin my audible five-second countdown. I will use only electrical igniters recommended by the motor manufacturer that will ignite rocket motors within one second of actuation of the launching switch. If my high power 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.
  13. Flying Conditions. I will launch my high power rocket only when the wind is no more than 20 miles per hour and under conditions where the rocket will not fly into clouds or when a flight might be hazardous to people, property, or flying aircraft. Prior to launch, I will verify that no aircraft appear to have flight paths over the launch site.
  14. Pre-Launch Test. When conducting research activities with unproven designs or methods I will, when possible, determine the reliability of my high power rocket by pre-launch tests. I will conduct the launching of an unproven design in complete isolation from persons not participating in the actual launching.
  15. Launch Angle. I will not launch my high power rocket so its flight path will carry it against a target. My launch device will be pointed within 20 degrees of vertical. I will never use rocket motors to propel any device horizontally.
  16. Recovery Hazards. If a high power rocket becomes entangled in a power line or other dangerous place, I will not attempt to retrieve it. I will not attempt to catch my high-power rocket as it approaches the ground.

Here is the very first "safety code" for model
rocketry. It was a vendor developed admonishion
by Rock-A-Chute company circa 1957.

Be safe not silly. Offset distances protect from motor
failures or thrust output only. Excessive distances
prevent owner and spectators from feeling the power.
The superior site set-up for groups is Misfire Alley
invented or first published by G. Harry Stine. The
placement or orientation of the launch site
relative to wind and spectators is important too.

Offset distances specific to static tests protect from
motor failures or thrust output. Unbarricaded assumes
the motor is in a fixed position stand nozzle up or
nozzle perpindicular to people who are to the side of
the motor and/or behind the nozzle side. The casing is
not steel. Barricaded distances assume there is a
multilayer wood wall or a wall with thick plexiglass
plate inset for viewing or photography. The primary
purpose for this guideline is for educational and
testing programs.
USR safe launch pad RADIUS guidelines
Combustable free for 10 feet radius
Very low combustable for 20 feet radius
Watering the area is not a substitute for removing
combustible materials. For fire supression do not
stomp on fires. Use shovels and blankets.
USR launch site width guidelines
1/4 the expected altitude
1/8 the expected altitude with
proven dual deployment system
1/2 the expected altitude if
3 stage or cluster of 8 or more or
unproven aerodynamic design
1/4 the expected altitude rule has been
proven in over 4 decades of operations.
Including by the legendary Centuri Engineering Company.



From the 1981 Centuri catalog page 36.


FAA airspace guidelines
faa

Federal Aviation Administration class G or uncontrolled airspace
is permissible for unmanned rockets without additonal clearance
up to 1200 feet above ground level (AGL).

Operations in controlled airspace requires an FAA waiver
(written permission) for rockets which have over either 125g
propellant or over 3.3 lb liftoff weight. Go to any local
airport for a sectional map and questions about controlled
airspace issues. They do not answer questions on waivers.

Obtain a waiver (form 7711-2 at pdf link) for FAA
and contact the regional service center to submit it.
This is easy for individuals, clubs, or groups. It is FREE but
requires 45-60 days advance notice. Authorizations are also
available for multiple dates or annually if you call in to
activate it as needed. Ask your FAA representative about details.
