(Figure 5) on the cylinder to burst, or the cylinder itself to rupture. A cylinder may
rupture with extremely dangerous force. Use properly rated disk only.
A scale must be used for all CO2 fills to prevent an overfill. A pressure gauge must
be used for all compressed gas or air fills to prevent an overfill.
Fills must be performed by qualified personnel.A cylinder must not be filled beyond the
cylinder’s capacity per the U.S. Department of Transportation. A cylinder’s rated capacity
appears on the cylinder itself.
