1. A compressed gas cylinder for a self-contained breathing apparatus, the cylinder including a pressure volume portion for containing a volume of gas pressurized to a service pressure of between about 5,000 psig and about 6,000 psig, the pressure volume portion having a length, a diameter, and a water volume;
wherein the pressure volume portion defines an operational parameter of the cylinder, the operational parameter being a relationship between free air capacity of the cylinder in liters and a rated service time in minutes, the operational parameter comprising one of: 1200 liters of free gas and 30 minutes of rated service time; 1800 liters of free gas and 45 minutes of rated service time; 2400 liters of free gas and 60 minutes of rated service time; and 3000 liters of free gas and 75 minutes of rated service time;
wherein at least one of the length and the diameter of the pressure volume portion is at least slightly less than at least one of a corresponding length and diameter of a compressed gas cylinder for a self-contained breathing apparatus having a service pressure of about 4500 psig; and
wherein the length and diameter of the pressure volume portion provide a weight reduction of from about 5% to about 12% as compared to a compressed gas cylinder for a self-contained breathing apparatus having a service pressure of about 4500 psig.
