1、Designation: F2856 11Standard Practice forTransfilling and Safe Handling of Small Paintball Cylinders1This standard is issued under the fixed designation F2856; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revis

2、ion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice is intended to satisfy the demand forinformation on the basic procedures for the safe handling andtransfilling of

3、small (not bulk) paintball CO2cylinders com-monly used with a paintball marker for propulsion of apaintball. This standard does not address issues dealing withthe transfilling, storage, and handling of supply cylinders thatmay be used in transfilling smaller cylinders.1.2 The CO2fill procedures are

4、written for the pressurecycling cylinder transfilling method most commonly used bypaintball field and/or store operators.1.3 This practice should not be confused with federal, state,provincial, or municipal specifications or regulations; insur-ance requirements; or national safety codes.1.4 This pra

5、ctice does not purport to address all of thesafety problems, if any, associated with the safe handling andtransfilling of small paintball cylinders. It is the responsibilityof the user of this standard to establish appropriate safetypractices and determine the applicability of regulatory limita-tion

16、ates.4. General Considerations4.1 Persons, who are transfilling carbon dioxide (CO2),must be trained in the hazards associated with liquid carbondioxide. Contact between exposed skin and cold piping, orcarbon dioxide can cause frost burns or can present otherhazardous situations.4.2 Always wear heav

17、y gloves and eye protection whilefilling cylinders.4.3 Always have the MSDS at the location that the fillingtakes place.4.4 Always read and understand all fill station instructions.4.5 Ensure that there is proper ventilation in the filling area.4.6 Warning posters should be posted near the filling o

18、pera-tion. These shall be of appropriate size and posted in a clearlyvisible location. See Fig. 1 and Fig. 2.4.7 The receiving cylinder (paintball cylinder) must be of arefillable type (that is, not disposable) and the net weight orvolume of gas that it can safely hold stamped on the shoulderor mark

19、ed on the cylinder.4.8 Supply cylinders must be secured and supported, suchas fastened to a wall or similar immovable structure (that is, notfree standing).4.9 It is recommended that siphon type bulk tank be used forfilling.Avoid using inverted bulk tanks unless done properly, asshown in CGA G-6.8.F

20、IG. 1 Example of Warning Poster AF2856 1124.10 Warning signs should be placed at the entrance toconfined areas where high concentrations of carbon dioxide gascan accumulate. These shall be of appropriate size and postedin a clearly visible location.5. Fill Stations5.1 Fill stations and related equip

21、ment should be rated to atleast 1800 psi working pressure.5.2 The transfer hose shall be compatible with liquid CO2and shall have a minimum service pressure of 3000 psi.5.3 Fill stations shall be supplied with instructions foroperation by the manufacturer or distributor of the product. SeeFig. 3 and

22、 Fig. 4.5.4 Fill stations should be marked or tagged with thefollowing safety warnings:5.4.1 Read owners manual before using.5.4.2 Use only with CO2.5.4.3 Close bulk tank valve when not in use.5.4.4 Vent down system.6. Cylinder Inspection6.1 Conduct a valve twist test on empty cylinders todetermine

23、if the valve is securely attached to the cylinder. Anycylinders which have valves that can be twisted by hand, orwhich show signs of the valve having been partially removed,must not be filled. The owners of such cylinders should beFIG. 2 Example of Warning Poster BF2856 113warned to have the valve r

24、epaired by the manufacturer or itsauthorized representative, prior to using the cylinder or attach-ing it to a marker. See Fig. 5.6.2 Look for a rotation indication mark between tank andbottle. Ensure line matches between two pieces. IF THE LINEDOES NOT MATCH DO NOT FILL THE CYLINDER. SeeFig. 6.6.3

25、If no line is present place a non removable, non etchingmarking between the valve and bottle for future checks.Apaintpen is a good item to use to apply the rotation indication mark.FIG. 3 Example of Fill Station Instruction Sheet AFIG. 4 Example of Fill Station Instruction Sheet BFIG. 5 Warning Labe

26、l From Specification F2553.F2856 1146.4 Visually inspect the cylinder condition before each fill.6.4.1 Cylinders must be stamped on the shoulder with aDOT (Department of Transportation) and potentially a TC(Transport Canada) mark, working pressure, manufacturerscode or name, serial number, hydrostat

27、ic test date and ratedCO2capacity. If no stamping is present or stamping has beenaltered or non legible, do not use the cylinder. See Fig. 7.6.4.2 The pressure rating stamped on the cylinder must be atleast 1800 psi.6.4.3 Cylinders must be in good condition: free of stickers,large dents, scrapes, bu

28、lges, obvious corrosion, pits, evidenceof fire damage and leaks.6.4.4 Cylinders should not be buffed or polished.6.4.5 Cylinders having valves without a rupture disk orpressure relief mechanism must not be filled.6.4.6 Pressure relief or rupture disk assembly should betight, and all pressure relief

29、passages should be clear ofobstructions. See Fig. 8.6.4.6.1 Cylinders must have correct burst disk as per Speci-fication F2030; 3AL-1800 CO2cylinders require a 3000 psi(3K) burst disk.6.4.7 The valve and external threading must not be dam-aged, and must be free of foreign material. The valve o-ringm

30、ust be in good condition in order to fill. Damaged valves orcomponents must be cleaned or repaired by the manufactureror its authorized representative, prior to filling the cylinder.6.5 Cylinders must NOT be filled if any one of the follow-ing conditions exists:6.5.1 Cylinders are outside the valid

31、test date range.6.5.1.1 Requalification period for CO2cylinders used inpaintball is five (5) years for 3AL aluminum and 3A and 3AAsteel bottles. There is no maximum life for a 3AL, 3A, and3AA cylinders as long as the cylinder passes visual andhydrostatic inspections.6.5.2 Aluminum cylinders not exce

32、eding 5 cm (2 in.)outside diameter and less than 61 cm (2 ft) in length are exemptfrom hydrostatic retesting.6.5.3 Presence of water or other liquids in the cylinder.6.5.4 Evidence of internal contamination such as rust orother particles.6.5.5 External corrosion exceeding 0.8 mm (0.032 in.) indepth

33、or 25 % of surface area.6.5.6 Dents in aluminum bottles that exceed 1.6 mm (0.062in.) with a diameter less than 50.8 mm (2 in.).6.5.7 Dents in steel bottles that exceed 1.6 mm (0.062 in.)with a diameter less than 10 times the depth of the dent.6.5.8 Scrapes or gouges that decrease the wall thickness

40、he CO2fill station to the supply cylinder. Ensurethat the CGA 320 fittings are used and installed correctly.Ensure that only one (1) correct sealing washer is used.6.10 Deactivate the universal fill adaptor (UFA). Attach thepaintball cylinder to the CO2fill station using the UFA.6.10.1 Invert the pa

41、intball cylinder, open paintball cylindervalve and/or activate the UFAand the blow-down valve to fullydischarge the remaining CO2.6.10.2 Weigh the empty cylinder. Determine the allowablenet weight of CO2and add this value to the empty cylinderweight. This provides the gross weight of a full cylinder

42、. Thebottle should be cool to the touch in order to receive the CO2.6.10.3 If no venting occurs, add 1 to 2 oz and repeat theinversion and depressurization.6.10.4 Conduct a valve twist test on the depressurizedcylinder as stated in 6.1 and 6.2.6.11 Fill the cylinder to the proper gross weight.6.11.1

43、 To fill the paintball cylinder, open the valve to thepaintball cylinder, activate the UFA, close the blow-downvalve, and open the supply valve to begin transfer of the CO2.6.12 To complete the transfilling process, close the supplyvalve, de-activate UFA and the valve of the paintball cylinder,and o

44、pen the blow-down valve to vent the supply line. Checkthe final weight of the paintball cylinder.6.13 If the final weight is below the allowable gross weightof the cylinder, close the transfer valve, open the blow-downvalve to relieve some pressure from the paintball cylinder andrepeat steps above f

45、or filling.6.14 If the final weight exceeds the allowable gross weightof the cylinder, vent the excess CO2. Do not overfill thecylinder.6.15 Turn off the supply tank, safely vent down the fillstation and if possible, remove or secure any hoses. Do notleave CO2in the fill station or hoses when not in
