4 4 of 14 12/30/ :56 AM First Revision No. 10-NFPA [ Section No ] A reloadable high power rocket motor shall not be altered except as allowed by the manufacturerand shall be certified by a recognized testing organization acceptable to the authority having jurisdiction to meet the certification requirements set forth in NFPA 1125, Code for the Manufacture of Model Rocket and High Power Rocket Motors. Submitter Information Verification Submitter Full Name: Brian OConnor Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Tue Aug 25 14:57:32 EDT 2015 Committee Statement Committee Statement: Response Message: References to certification of high power rocket motors in this paragraph are unnecessary and redundant to the requirements already stated in that only certified high power motors may be used, and to the requirements for recognition of the certification organization that are already stated in NFPA 1125 and that belong in that code, not in a consumer user code like NFPA Public Input No. 7-NFPA [Section No ]

5 5 of 14 12/30/ :56 AM First Revision No. 12-NFPA [ New Section after ] An ignition device shall be permitted to be installed into a vented hybrid rocket motor at any time. Submitter Information Verification Submitter Full Name: Brian OConnor Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Tue Aug 25 15:00:07 EDT 2015 Committee Statement Committee Statement: Response Message: Some types of hybrid rocket motor require installation of the ignition device during assembly and there is no way to postpone that installation. Motors of this type have been certified for some time (Rattworks K240 for example) and are in use. Vented hybrid rocket motors are not filled with oxidizer until they are at the pad requires that the same minimum safe distance be used during filling as during launching. Because the rocket motor is non-propulsive until filled with oxidizer, this creates no safety hazard. Public Input No. 6-NFPA [New Section after ]

8 8 of 14 12/30/ :56 AM B.2 Code.

9 9 of 14 12/30/ :56 AM The following is excerpted from the Model Rocket Safety Code. 1. Certification. I will only fly high power rockets or possess high power rocket motors that are within the scope of my user certification and required licensing. 2. Materials. I will use only lightweight materials such as paper, wood, rubber, plastic, fiberglass, or when necessary ductile metal, for the construction of my rocket. 3. Motors. I will use only certified, commercially made rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer. I will not allow smoking, open flames, nor heat sources within 25 ft of these motors. 4. Ignition System. I will launch my rockets with an electrical launch system, and with electrical motor igniters that are installed in the motor only after my rocket is at the launch pad or in a designated prepping area. My launch system will have a safety interlock that is in series with the launch switch that is not installed until my rocket is ready for launch, and will use a launch switch that returns to the off position when released. If my rocket has onboard ignition systems for motors or recovery devices, these will have safety interlocks that interrupt the current path until the rocket is at the launch pad. 5. Misfires. 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. 6. Launch Safety. I will use a 5-second countdown before launch. I will ensure that no person is closer to the launch pad than allowed by the accompanying Minimum Distance Table, and that a means is available to warn participants and spectators in the event of a problem. I will check the stability of my rocket before flight and will not fly it if it cannot be determined to be stable. 7. Launcher. I will launch my rocket from a stable device that provides rigid guidance until the rocket has attained a speed that ensures a stable flight, and that is pointed to within 20 degrees of vertical. If the wind speed exceeds 5 mph I will use a launcher length that permits the rocket to attain a safe velocity before separation from the launcher. I will use a blast deflector to prevent the motor's exhaust from hitting the ground. I will ensure that dry grass is cleared around each launch pad in accordance with the accompanying Minimum Distance table, and will increase this distance by a factor of 1.5 if the rocket motor being launched uses titanium sponge in the propellant. 8. Size. My rocket will not contain any combination of motors that total more than 40,960 N-sec (9208 lb-sec) of total impulse. My rocket will not weigh more at liftoff than one-third of the certified average thrust of the high power rocket motor(s) intended to be ignited at launch. 9. Flight Safety. I will not launch my rocket at targets, into clouds, near airplanes, nor on trajectories that take it directly over the heads of spectators or beyond the boundaries of the launch site, and will not put any flammable or explosive payload in my rocket. I will not launch my rockets if wind speeds exceed 20 mph. I will comply with Federal Aviation Administration airspace regulations when flying, and will ensure that my rocket will not exceed any applicable altitude limit in effect at that launch site. 10. Launch Site. I will launch my rocket outdoors, in an open area where trees, power lines, buildings, and persons not involved in the launch do not present a hazard, and that is at least as large on its smallest dimension as one-half of the maximum altitude to which rockets are allowed to be flown at that site or 1500 ft, whichever is greater. 11. Launcher Location. My launcher will be 1500 ft from any inhabited building, or from any public highway on which traffic flow exceeds 10 vehicles per hour, not including traffic flow related to the launch. It will also be no closer than the appropriate Minimum Personnel Distance from the accompanying table from any boundary of the launch site. 12. Recovery System. I will use a recovery system such as a parachute in my rocket so that all parts of my rocket return safely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery system wadding in my rocket. 13. Recovery Safety. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places, fly it under conditions where it is likely to recover in spectator areas or outside the launch site, nor attempt to catch it as it approaches the ground.

11 11 of 14 12/30/ :56 AM The following text is the High Power Rocket Safety Code in its entirety. (1) Certification. I will only fly high power rockets or possess high power rocket motors that are within the scope of my user certification and required licensing. (2) Materials. I will use only lightweight materials such as paper, wood, rubber, plastic, fiberglass, or when necessary ductile metal, for the construction of my rocket. (3) Motors. I will use only certified, commercially made rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer. I will keep smoking, open flames, and heat sources at least 25 ft away from these motors. (4) Ignition System. I will launch my rockets with an electrical launch system, and with electrical motor igniters that are installed in the motor only after my rocket is at the launching or prepping area. My launch system will have a safety interlock that is in series with the launch switch that is not installed until my rocket is ready for launch, and will use a launch switch that returns to the "off" position when released. The function of onboard energetics and firing circuits will be inhibited except when my rocket is in the launching position. (5) Misfires. 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. (6) Launch Safety. I will use a 5-second countdown before launch. I will ensure that a means is available to warn participants and spectators in the event of a problem. I will ensure that no person is closer to the launch pad than allowed by Table B.2. When arming onboard energetics and firing circuits I will ensure that no person is at the pad except safety personnel and those required for arming and disarming operations. I will check the stability of my rocket before flight and will not fly it if it cannot be determined to be stable. When conducting a simultaneous launch of more than one high power rocket I will observe the additional requirements of NFPA (7) Launcher. I will launch my rocket from a stable device that provides rigid guidance until the rocket has attained a speed that ensures a stable flight, and that is pointed to within 20 degrees of the vertical. If the wind speed exceeds 5 miles per hour I will use a launcher length that permits the rocket to attain a safe velocity before separation from the launcher. I will use a blast deflector to prevent the motor's exhaust from hitting the ground. I will ensure that there is no dry grass within a clear distance of each launch pad determined by Table B.2, and will increase this distance by a factor of 1.5 and clear that area of all combustible material if the rocket motor being launched uses titanium sponge in the propellant. (8) Size. My rocket will not contain any combination of motors that total more than 40,960 N-sec (9208 lb-sec) of total impulse. My rocket will not weigh more at liftoff than one-third of the certified average thrust of the high power rocket motor(s) intended to be ignited at launch. (9) Flight Safety. I will not launch my rocket at targets, into clouds, near airplanes, or on trajectories that take it directly over the heads of spectators or beyond the boundaries of the launch site, and will not put any flammable or explosive payload in my rocket. I will not launch my rockets if wind speeds exceed 20 mph. I will comply with Federal Aviation Administration airspace regulations when flying, and will ensure that my rocket will not exceed any applicable altitude limit in effect at that launch site. (10) Launch Site. I will launch my rocket outdoors, in an open area where trees, power lines, occupied buildings, and persons not involved in the launch do not present a hazard, and that is at least as large on its smallest dimension as one-half of the maximum altitude to which rockets are allowed to be flown at that site or 1500 ft, whichever is greater, or 1000 ft for rockets with a combined total impulse of less than 160 N-sec, a total liftoff weight of less than 1500 g, and a maximum expected altitude of less than 610 m (2000 ft). (11) Launcher Location. My launcher will be at least one half the minimum launch site dimension, or 1500 ft (whichever is greater) from any occupied building, or from any public highway on which traffic flow exceeds 10 vehicles per hour, not including traffic flow related to the launch. It will also be no closer than the appropriate Minimum Personnel Distance from Table B.2 from any boundary of the launch site. (12) Recovery System. I will use a recovery system such as a parachute in my rocket so that all parts of my rocket return safely and undamaged and can be flown again, and I will use only flameresistant or fireproof recovery system wadding in my rocket.

12 12 of 14 12/30/ :56 AM (13) Recovery Safety.
