2018 standard competition rules

1. All pumpkins (fruit) fired must remain intact until they impact the ground to obtain an official measurement (impact center).

2. No part of the machine shall cross the firing line.

3. No Wadding (including bean chaff, straw, foam, metal, or any other object.)

4. No explosives, chemicals, or gases are allowed. 

5. Pumpkins are not to be altered in any way, excluding ICC (International Chunkin Coalition) marker paints. All pumpkins must be in their natural state. Pumpkins fired from machines during competition will be measured from the survey teams designated point of measurement. Your pit # may be written on your pumpkin to help in the identification in the landing zone (This is strongly recommended).

6. ICC accepted fruit varieties are: La Estrella, Sugar Pumpkin, White Lumina, Jarrahdale  (others may be submitted to the ICC agriculture chair for consideration/ evaluation /approval).

7. The ICC reserves the right to combine any divisions if there is a lack of participation. Any division that is subject to cutting will be contacted to see where they want to be moved.  This will mean they must meet the full qualifications of the class they move to. All divisions must have two (2) entries in that division to open it to competition. If any division is cut for the year it will need 2 entries to open it again in the future. Machines can only enter one (1) division per machine. Teams entering two machines on the same trailer in the same division may do so; provided they do not share components and they pay for both entries.

8. All Machines must be able to fire within three (3) minutes. Keep in mind that every attempt is made to give you (20) minutes by informing you 4 machines or more down the firing line. Any machine not able to fire when the pit boss decides your three (3) minutes are up, will forfeit that round. No exceptions! Team captains are responsible for making sure they get their pumpkin weighed well enough in advance to ensure they have time they need to set up. Team Captains are responsible for making sure you are ready when it’s your turn to chunk.

9. Lost Pumpkin: If a team’s shot is unable to be found by the ICC spotters, it will be declared a “Lost Pumpkin” by the Pit Boss. The Pit Boss will give the team captain the option to either forfeit the shot or take a make-up shot. For this instance, teams shall always have an additional pumpkin ready. The Pit Boss will decide when the make-up shot will occur and whether the machine needs to be repositioned prior to making the make-up shot.

10. If you are disqualified for any round in competition for breaking Safety and General rules you will forfeit your longest distance, not the distance of the shot you are being disqualified on.

11. When using an 8-10 lb. Pumpkin the longest distance of the event is the World Champion Extreme Chunker and wins the overall chunk regardless of division. All other first place winners are Champions of division entered.

12. It is the responsibility of the prior year's champion to return the traveling trophy to the current year’s International Chunkin Coalition event in NH. The trophy must be kept in good condition and exhibited in good taste!

13. The current World Champion Chunker has the right to elect to fire either first or last (of their division). This selection for both days must be made and approved before the end of the first Captain’s meeting. The selection must be approved by the Pit Boss.

14. The ICC is not responsible for any equipment needs you may have once on the field. If you need equipment to set up or disassemble your machine, you must make those arrangements prior to the event. Teams will no longer be allowed to operate equipment rented by the association for insurance purposes. Note: The field is composed of predominately gravel based soils and drains well.

15. All machines must be set up in the assigned areas. You will be given notice of this area well in advance. No excuses will be entertained for not being in your spot (on game day). You will be required to move if you are in the wrong spot.

16. All machines and equipment used by chunkers must be removed from the field within (1) day after the event. Owner or team captain will pay towing and storage expenses for machine or equipment left on field after the deadline. Machines that will need to exit the field prior to the end of competition each day will need to notify the Safety and Security Committees (ICC) at the captains’ meeting on the day they wish to remove their equipment. Safety and Security Committees reserve the right to deny any request based on safety.

17. Extreme Chunk Identification badges should be worn at all times. You will not be permitted in the pits with the machines without your badge. No Exceptions.

18. All youth (under 18) in pits must be under adult supervision at all times. (Example: Youth could fire machine while unattended and be injured or injure someone else.)

19. No campers, tents or any overnight camping is allowed in pits. You must camp in the designated NHMS camping area. Camp Fires are governed by the NH State Burning regulation (Loudon NH) . NHMS must give approval for a campfire. www.nhms.com

20. No glass bottles will be permitted on the premises.

21. No pets are allowed in the pits. Service animals only - please notify an ICC official of their presence.

22. All persons entering the pits must sign a ICC Liability Release/waiver Form. This should be done ahead of the event - waivers are part of the Team Registration packages. Please be sure to have signed your teams common waiver form. This is absolutely mandatory.

23. All machine captains and teammates are to follow ICC Rules or you will be penalized or disqualified, depending on the nature of which rule is broken. If you are penalized, you will forfeit your chance to chunk in that round of competition, if disqualified, you will be referred to rule #10 of the General Rules. Major infractions that are deemed as challenging the safety of the chunk and/or others around your machine will be discussed during a quorum of The Safety and Rules Committee to decide on the actions to take. The results of the Quorum will be relayed to the team captain. There will be Zero Tolerance for those who break safety rules.

24. Machines may not chunk until the safety inspector approves them and deems them to be safe per the ICC Safety & Rules. Any alterations after being inspected will require another inspection to be able to fire. If your machine has been inspected and you alter it, you will need to be re-inspected by a safety inspector official in order to fire again. The safety inspector may require the team captain to fire their machine during the inspection process to ensure the machine is safe enough to compete at the World Championship Chunk.

25. It is at the discretion of the Safety Inspector to require a 15 min. fully cocked stress test and test fire to ensure public safety. This is expected for new teams who have never proven performance on the field during a National event. It is also expected for teams who have made modifications from the previous year that change the fit, form, or function of the design being introduced in the new year such that it constitutes a design change in the equipment’s ability to perform a repeat of its intended function. 

Fit- a change such that the component is different in how it is installed from a previous approved installation method by the Association.

Form- A change in the form of any component such that its alteration deviates from code, standards, or demonstrated common practices like OSHA, ASME, or other standards expressed by the ICC.

Function- any change that changes the design function of any component such that the safety committee needs to inspect welds, knots, bolting, cable clamps, or any other mechanical attributes for proper use.

In all cases, Inspections focus on the welfare and safety of the general public and the chunkers. Changes made by the teams are to be pointed out by the captain for teams who have been inspected in the prior year’s event. New Teams will get a full inspection for ability to meet requirements.

26. Ceasefire:

No machine is to fire when a cease fire has been ordered. If you are locked and loaded or pressurized at this time, contact security, pit boss, safety committee, so you can safely discharge or relieve your machine.

27. All members and/or captains are to contact a safety official before climbing on any machine during competition and must have clearance from the safety committee. No one is to climb any machine while cocked, elevated or in a dangerous situation. Teams using ladders to assemble, Load, repair, or dismantle equipment must have a spotter to hold the ladder and/or a tie off to the ladder to prevent injury. Teams are expected to use a safety harness when climbing over 8 feet above the ground.

28. The ICC reserves the right to request a team captain to dismantle his or her machine to inspect for foul play. For example, use of any propellant other than compressed air. If you are caught using any chemicals (Nitrogen, Helium, Hydrogen or any illegal substances other than compressed air) you will be banned from the Extreme Chunkin competition.

29. All team captains must sign the field roster stating that they have received, read, and understand the rules of the ICC. This sheet will be on the field and given to the pit boss, if it is not signed, you do not chunk. All team captains must attend all safety field meetings. If the daily meeting roster is not signed at the end of the morning meeting you will not be tracked down and the team will not compete that day of competition. Please sign the acknowledgement sheet.

30. Safety committee/ICC officials end of day meeting – The safety committee/ICC officials will meet at approximately 4 PM meeting each day. If you have safety issues to present, we welcome team captains to do so at this time. Note: No inspections after dark.

31. Spotters:

Only 1 spotter per team and the ICC association spotters will be allowed on the landing field. They must sign in & out at designated area. All spotters on motorized vehicles will operate their vehicles responsibly at their own risk. No drinking, drugs or alcohol tolerated. All team spotters shall remain in the spotter safety shelters until the pumpkin has made contact with the ground. Team spotters must follow the orders and directions of the head spotter/surveyor on the field. Helmets are required for all spotters and only Side by Side (utility vehicles are allowed) no single seat 4 wheelers, no 3 wheelers, no dirt bikes.

32. Vehicle Rules: 

A. No children under 18 will be allowed to drive golf carts. They may ride with an adult that has a valid driver’s license.

B. All golf carts,  must be registered with the ICC and display the provided license plate on the front and rear of the vehicle. 2 golf carts per team permitted.

C. No golf carts, are permitted on the field beyond firing line unless you are an association official or spotter actively engaged in spotting pumpkins. (All spotters refer to rule #9)

All motor vehicles that may transport occupants in any fashion must operate at a safe speed. If a vehicle is deemed unsafe by security, depending on severity, can result in team punishment.

33. Any machine found to have structural defects (weld fractures affecting the pressure vessel, load beams, firing pins, any load bearing members, supports or support subsystems) will be banned from chunking until repaired and re-inspected by a member of the safety committee. No Exceptions.

34. Backstops will be required for any machine that can fire backwards (Regardless of previous performance). Teams may make their own backstops for the chunk but they must be constructed to a ICC approved design standard. Any machine inspected on the field or approved in advance, as “not able to fire backwards” will be exempt from this requirement. Machines marked for backstops that fire without one will be disqualified from the chunk. This includes anytime they fire while on the field. Yes, a natural tree line back stop can qualify for a backstop as long as no spectators are behind it.

35. Small holes for stabilizers will be permitted. A 24”x24”x24” hole is acceptable and must be filled, tamped and topsoil replaced before leaving pit area. It is your responsibility to keep pedestrians from falling in your hole. The soil is gravel based not soft loam - plan accordingly. Leave No Trace.

36. Hard hats, ear and eye protection to be worn by all fire line personnel in pit when firing. Everyone in the pit areas must have a hard hat on at all times. Hard hats must be worn 100% of the time by everyone in the pit areas during the entire event. This is mandatory and you will be asked to leave the pit area if you don't have a hard hat on. Thank you!

37. Each Machine must have Fire Extinguisher mounted to machine and First Aid Kit in plain view and clearly marked for all people to see.

38. All cables and cable clamps must be sized, installed, and torqued properly to the particular manufacturer’s recommendations. All shackles on a machine must have a metal safety tie on the pin to prevent the pin from loosening.

39. Lag bolts shall not be permitted in load bearing applications. Lag bolts are considered low end load bearing components and will not be approved in any application where stress can fatigue the lag or the hole made for it. The approved method of attachment is with carriage, shoulder, or hex head bolts with washers and backing plates, which shall be a minimum of SAE Grade 5 (or Metric 8.8 Class) with lock nuts of similar design.

40. All winches and or cocking devices will need safety cages. Winch operators must be protected at all times when cocking their machine, or throwing device. This is for any team who is placed in the line of fire during winch operation. If you are in the line of fire of the winch, the machine must have a safety cage installed between the team member in the line of fire and the winch in case of winch or cable failure. The safety cage shall be installed in such a manner that it will not deflect in any direction whatsoever when manual force is applied.

41. Inspect all hydraulic lines each time you cock or lift your machine. Make sure winches can handle the load and cables are in good condition. Make sure your release mechanisms are heavy enough to handle the load. Make sure you have an automatic brake or a dog lock on winch or cocking device.

42. All cannons must be secured to prevent upward recoil. It is the machine designer’s responsibility to make sure winch and cables can handle the load put on them.

43. Compressed air machines must have a bleed off device (valve) to allow for safely removing the air if the machine cannot be fired. This device should be installed so that it does not blow directly to the dirt or face level to prevent Eye injury. If it is exposed to the body level it should have a shield installed to deflect the air. All Air inlets on tank must have a Check Valve Installed. Pop off relief safety valves must have plastic shipping plugs removed when pressurizing any cannon or machine. Pop off relief safety valves are not to be altered or held down to prevent popping off. Pop off relief valves are not to be reclosed after opening on their own while machine is being pressurized to fire.

44. All sections of your cannon barrel must be properly secured so that they will not separate and will stay stationary. Make sure you do not pinch or collapse your barrel when using aluminum barrel. Use only flanged and bolted methods to connect sections if need be - NO band clamps. All cannons not using an actuated valve powered by air or some other mechanical device must have a spring loaded normally open valve. The use of Plastic Polyvinyl Chloride (PVC) will not be allowed for air cannon barrels, due to the safety hazard of this type of pipe. This pipe is not for compressed air. The manufacturer of the pipe states it is unsafe to transport air in PVC pipe no matter what schedule you use. Air vessels made of PVC will be illegal. No PVC or plastic is allowed in pressurized areas of the vessel. A smaller A.S.M.E. relief valve can be placed on the vessel when the operation requires the tank to be filled from a cylinder tank. This valve will be set at or below the allowable working pressure of the vessel. All relief valves must be maintained in proper working order during operation of the machine.

45. Aluminum barrels suspended by cables must have the cables anchored to a substantial base to prevent whipping around. Plastic coated cable will not be allowed.

46. All portable air storage vessels (high pressure air cylinders) used to fill their cannon must be stood upright and secured to a stationary device. No tanks or vessels may be stored lying down on the ground or transported lying down in any vehicle. Every vessel must have a safety cap on it when not in use. All nipples, fittings, manifolds, or airlines must be capable of handling the pressure of air on them. This is your responsibility. All propane tanks must be secured to a stationary device.

47. Any air vessel under 5 cu. ft. is the responsibility of the owner or team captain to make sure it is safe to use. If the safety committee feels your vessel is not safe due to rust, pitted or damage, you will have to correct the problem before the vessel can be used.

48. Hoses must be in good operating condition. Chafed or cut hoses must not be used. If using Chicago type quick connects, safety pins must be installed in each of the two holes. Any recommended safety equipment designed for any type of coupler must be used!  All air lines 1” in diameter and larger must be cabled to a stationary device. No radiator style clamps shall be used on any high pressure air lines, regardless of size.

49. All catapult and trebuchet machines must have a safety strap or mechanism to hold the throwing arm or boom in case of misfire when loading. You are responsible for making sure everyone stays clear of your machine, in case of a misfire. Personnel handling ropes or cable should wear gloves such as a sailing or repelling type to prevent burns.

50. All Team Captains are responsible for clearing the areas around and behind their machines while cocking or firing machines at all times.

51. All machines must be fully relieved before being loaded. (Example: Do not load cannon while pressurizing tank.)

52. No machine may fire or discharge without sounding a horn or warning device. 3 blasts of the horn are required so spotters are aware.

53. All Machines require a safety inspection.

54. To avoid costly time and ensure streamlined safety inspections, it shall be the responsibility of the team Captain, when calling for the inspection, to ensure that the machine in question is fully ready to fire. Failure to follow this rule will automatically place the team at the bottom of the inspection list. For the purposes of this rule “ready to fire” shall be defined as the machine fully assembled, the team Captain present, all safety devices functional and engaged where required and all pertinent safety equipment in the assigned pit area available and ready for use.

Air Cannon Rules:

1. Pumpkins must weigh between 8 & 10 pounds.

2. “Compressed air only” No Gases, No chemicals, No gun powder

3. Pumpkin must be loaded before Pressurizing vessels, and an ICC Official must see you load it.

4. All Air inlets on vessel must have a Check Valve Installed.

5. Horn or sound device must sound prior to firing down range for safety of spotter on the field. 3 Blasts of the horn.

6. All Safety and General rules apply as well.

7. All pressure vessels shall be built to the American Society of Mechanical Engineers (A.S.M.E.) construction codes. The vessels will have a manufactures nameplate with proper (A.S.M.E.) stamping and will be marked with the vessel’s allowable working pressure.

8. All pressure vessels shall be equipped with A.S.M.E. approved and sealed relief valve set at or below the allowable working vessel. The relief valve will need approval by the boiler safety so it is recommended you contact them before purchasing the valve. The owner/user shall assure that the relief valve(s) is functional at all times. The relief valve(s) may be tested by the owner/user at the time of inspection.

9. Each vessel shall be inspected by the New Hampshire Division of Boilers safety and issued an operating certificate if the vessel meets all the requirements for operations in the State of New Hampshire. These certificates are valid for four years from the date of inspection/ issuance. This certificate must be in hand before machine can enter the field. Or if reciprocal with NH Boiler Dept - you may hand in a certificate from your home state (Ex: Delaware is reciprocal with NH).

10. Each grandfathered vessel (meaning having already competed at the national Delaware event in previous years) shall have a hydrostatic test conducted in accordance with the test procedures in the national board inspection code. Each Grandfathered vessel must be hydrostatically tested every two years and witnessed by a National Board Commissioned inspector and the results recorded and presented at time of inspection by the Boiler Safety. If a third party National Board Commissioned inspector is not used, a Boiler Safety inspector can witness the test on any vessel upon request. If out of state vessels are to be inspected by a Boiler Safety inspector the vessel must be in New Hampshire no later than Wednesday before the event. 

11. A.S.M.E. vessels in operation, prior to the 2004 Chunk are considered (Grandfathered) under these conditions. Any future alterations and repairs made to the pressure vessel must meet the National Board of Boilers and Pressure Vessel Inspectors Code (NBIC). Any air cannons constructed after the 2004 event must meet existing Department regulations.

12. All vessels regardless of origination, operated at the event must meet these requirements.
