(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 or store operators, or both.
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, health, and environmental practices and determine the applicability of regulatory limitations, such as and not limited to DOT, CGA, and OSHA, prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
