(Practice)Standard Practice for Transfilling and Safe Handling of Small CO2 Cylinders for Use in Paintball
Standard Practice for Transfilling and Safe Handling of Small CO<inf>2</inf> Cylinders for Use in Paintball
ABSTRACT
This practice covers basic procedures for the safe handling and transfilling of small paintball carbon dioxide cylinders for pressure cycling cylinder transfilling method most commonly used by paintball field and/or store operators. The basic standards presented herein should not be confused with federal, state, provincial, or municipal specifications or regulations, insurance requirements of national safety codes. Cylinder inspection include: conducting valve test twist on empty cylinders to ensure the valve is properly attached, checking on the rotation indication mark between tank and bottle, avoiding of polishing and rebuffing of cylinders and avoiding of refilling ruptured tanks. Safety procedures also include checking on pressure relief passages from any obstructions, inspecting on the correct burst disk as specified, avoiding of refilling cylinders failing to meet specified requirements, inspecting safety relief device, cylinder wall, and the valve body of cylinders as specified.
SCOPE
1.1 This practice is intended to satisfy the demand for information on the basic procedures for the safe handling and transfilling of small (not bulk) paintball CO2 cylinders commonly used with a paintball marker for propulsion of a paintball. This standard does not address issues dealing with the transfilling, storage, and handling of supply cylinders that may be used in transfilling smaller cylinders.
1.2 The CO2 fill procedures are written for the pressure cycling cylinder transfilling method most commonly used by paintball field and/or store operators.
1.3 This practice should not be confused with federal, state, provincial, or municipal specifications or regulations; insurance requirements; or national safety codes.
1.4 This practice does not purport to address all of the safety problems, if any, associated with the safe handling and transfilling of small paintball cylinders. It is the responsibility of the user of this standard to establish appropriate safety practices and determine the applicability of regulatory limitations, such as and not limited to DOT, CGA, and OSHA, prior to use.

3.1.5.1 Discussion—
If the valve does move, the valve and bottle should not be filled and should be repaired and/or serviced by the manufacturer or
its authorized representative. If the valve does not move then the valve passes the test and may be filled provided it passes all other
requirements. The test should only be done when the cylinder is empty and without any tools.
3.2 Acronyms:
3.2.1 DOT—department of transportation

4. General Considerations
4.1 Persons, who are transfilling carbon dioxide (CO ), must be trained in the hazards associated with liquid carbon dioxide.
Contact between exposed skin and cold piping, or carbon dioxide can cause frost burns or can present other hazardous situations.
4.2 Always wear heavy gloves and eye protection while filling cylinders.
4.3 Always have the MSDS at the location that the filling 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 Warning posters should be posted near the filling operation. These shall be of appropriate size and posted in a clearly visible
location. See Fig. 1 and Fig. 2.
4.7 The receiving cylinder (paintball cylinder) must be of a refillable type (that is, not disposable) and the net weight or volume
of gas that it can safely hold stamped on the shoulder or marked on the cylinder.
4.8 Supply cylinders must be secured and supported, such as fastened to a wall or similar immovable structure (that is, not free
standing).
4.9 It is recommended that siphon type bulk tank be used for filling. Avoid using inverted bulk tanks unless done properly, as
shown in CGA G-6.8.
4.10 Warning signs should be placed at the entrance to confined areas where high concentrations of carbon dioxide gas can
accumulate. These shall be of appropriate size and posted in a clearly visible location.
5. Fill Stations
5.1 Fill stations and related equipment should be rated to at least 1800 psi working pressure.
5.2 The transfer hose shall be compatible with liquid CO and shall have a minimum service pressure of 3000 psi.
5.3 Fill stations shall be supplied with instructions for operation by the manufacturer or distributor of the product. See Fig. 3
and Fig. 4.
5.4 Fill stations should be marked or tagged with the following safety warnings:
5.4.1 Read owners manual before using.
5.4.2 Use only with CO .
5.4.3 Close bulk tank valve when not in use.
5.4.4 Vent down system.
6. Cylinder Inspection
6.1 Conduct a valve twist test on empty cylinders to determine if the valve is securely attached to the cylinder. Any cylinders
which have valves that can be twisted by hand, or which show signs of the valve having been partially removed, must not be filled.
The owners of such cylinders should be warned to have the valve repaired by the manufacturer or its authorized representative,
prior to using the cylinder or attaching it to a marker. See Fig. 5.
6.2 Look for a rotation indication mark between valve and bottle. Ensure line matches between two pieces. IF THE LINE DOES
NOT MATCH DO NOT FILL THE CYLINDER. See Fig. 6.
