Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis standard is intended to provide basic procedures for the safe handl
3、ing and transfilling of small(not bulk) paintball compressed air cylinders commonly used with a paintball marker for propulsionof a paintball.This practice is written within the current state-of-the-art of transfilling compressed gas technology.The intent is to revise this specification whenever sub
4、stantive information becomes available whichjustifies revising existing requirements or adding new requirements.1. Scope1.1 This practice is intended to satisfy the demand forinformation on the basic procedures for the safe handling andtransfilling of small (not bulk) paintball compressed air cylin-
5、ders commonly used with a paintball marker for propulsion ofa paintball. 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 compressed air fill procedures are written for thepressure
6、cylinder transfilling method most commonly used bypaintball field or store operators, or both.1.3 This document should not be confused with federal,state, provincial, or municipal specifications or regulations;insurance requirements; or national safety codes.1.4 The values stated in inch-pound units
7、 are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibil
8、ity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations, such as and not limited to DOT,CGA, and OSHA, prior to use.2.

15、of a shell and a fill,conforming to Specification F1979 and designed to be expelledfrom a paintball marker conforming to Specification F2272.4. General Considerations4.1 Persons, who are transfilling compressed air, should betrained in the hazards associated with compressed air ornitrogen, or both.4
16、.2 Always wear eye protection while filling cylinders.4.3 Always have any required MSDS at the location that thefilling takes 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 The receiving cylinder (paintball cylin
17、der) must be of arefillable type (that is, not disposable) and pressure rating thatit can safely hold stamped or marked on the cylinder.4.7 Supply cylinders must be secured and supported, suchas fastened to a wall or similar immovable structure (that is, notfree standing).5. Fill Stations5.1 Fill st
18、ations and related equipment should be rated thesame as the supply tank.5.2 Fill stations should be used for the purpose of transfill-ing compressed air or nitrogen, or both, for the paintballindustry only.5.3 Fill stations shall be supplied with instructions by themanufacturer or distributor of the
19、 product.5.4 Fill stations should be marked or tagged with safetywarnings.5.4.1 Read owners manual before using.5.4.2 Use only with compressed air or nitrogen.5.4.3 Do not use for oxygen.5.4.4 Close bulk tank valve when not in use.5.4.5 Vent down system.5.4.6 Never add or introduce oil to the fill s
20、tation, cylinder,or regulator/valve.6. Cylinder Inspection6.1 Ensure that the regulator is properly attached to thecylinder.6.2 Ensure that the regulator is in good, serviceable condi-tion.6.2.1 Ensure that the proper cylinder safety burst disk isinstalled correctly.6.3 Visually inspect the cylinder

Ensure thatthe proper CGA fittings are used and installed correctly.7.5 Attach the paintball cylinder to the fill station using themale fill valve only. Ensure that the female quick disconnect isfully seated and closed.7.6 Holding onto the bottle
43、 or hose, or both, slowly open thesupply valve and fill the cylinder to the designated fill pressure.Check the output gauge on the fill station to ensure no overpressurization has occurred. Vent immediately if cylinder hasbeen over pressurized.7.6.1 The fill rate should be conducted at a speed thatm
44、inimizes heat build up. Care must be taken to fill the cylinderat a rate so the cylinder temperature does not become too hotto hold in your bare hands, 140F/49C.7.7 Close the supply valve, and open the blow-down valveto relieve the pressure in the transfer line. If the system isleaking through the v
45、enting valve, do not remove the cylinderuntil all air has stopped.7.7.1 If the system leaks through the blow-down valve thenthe fill valve assembly on the system needs to be serviced bythe manufacturer or its authorized representative. Do not addoil to the system.7.8 Remove the cylinder from the fil
46、l station. If the femalequick disconnect slide does not move easily, this may indicatethat pressure is still present in the system. Do not remove withpressure still in fill system.7.9 Turn off the supply tank, safely vent down the fill stationand if possible, remove or secure any hoses.8. Keywords8.
