(17.3 mm), comprised 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
18、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 thefilling takes place.4.4 Always read and understand all fill station instructions.4.5 Ensure that there is proper ventilation in
19、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 marked on the cylinder.4.7 Supply cylinders must be secured and supported, suchas fastened to a wall or similar immovable struc
20、ture (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 purpose of transfill-ing compressed air or nitrogen, or both, for the paintballindustry only.5.3 Fill stations shall be supplie
21、d 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.5.4.2 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 Ven
