General Considerations4.1 Persons, who are transfilling compressed air, should betrained in the hazards associated with compressed air ornitrog
15、en, or both.4.2 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 (pa
16、intball cylinder) 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 Statio
17、ns5.1 Fill stations 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 distr

If a condition not described in Section 6 is found andis of concern of the person transfilling the cylind
40、er, the cylindermust not be filled.7.2 The pressure rating stamped or labeled on the cylindermust meet or exceed the intended 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 inspect
41、ed forburnelling on the retaining ring area. Any type of hosing ortransfer line must also be inspected for proper pressure 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 stat
42、ion using themale fill valve only. Ensure that the female quick disconnect isfully seated and closed.7.6 Holding onto the 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 overpressurizat
43、ion has occurred. Vent immediately if cylinder hasbeen over pressurized.7.6.1 The fill rate should be conducted at a speed 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 t
44、he supply valve, and open the blow-down valveto relieve the pressure in the transfer line. If the system isleaking through 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 b
45、e serviced bythe manufacturer or its authorized representative. Do not addoil to the system.7.8 Remove the cylinder from 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
