15、ing 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.4.2 Always wear eye protection while filling cylinders.4.3 Always have any required MSDS at the location that thefi

16、lling 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 cylinder) must be of arefillable type (that is, not disposable) and pressure rating thatit can safely hold stamped or m

17、arked 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 stations and related equipment should be rated thesame as the supply tank.5.2 Fill stations should be used for the p

18、urpose 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 product.5.4 Fill stations should be marked or tagged with safetywarnings.5.4.1 Read owners manual before using.5.

19、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 station, cylinder,or regulator/valve.6. Cylinder Inspection6.1 Ensure that the regulator is properly attached to th

20、ecylinder.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 condition before each fill.6.3.1 Cylinders must be stamped or labeled with a DOT(Department of Transportation) or

40、l cylinders to be transfilled must be inspected as described inSection 6. If a condition not described in Section 6 is found andis of concern of the person transfilling the cylinder, the cylindermust not be filled.7.2 The pressure rating stamped or labeled on the cylindermust meet or exceed the inte

41、nded fill pressure.7.3 The female quick disconnect must be inspected forproper pressure rating and for wear on the retaining ballbearings. The male fill valve must also be inspected forburnelling on the retaining ring area. Any type of hosing ortransfer line must also be inspected for proper pressur

42、e rating.7.4 Attach the fill station to the supply 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

43、 bottle 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 spee

44、d thatminimizes 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 throug

45、h the venting 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

46、the fill 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. Key
