portable 7 kg extinguishers should be in accordance with
MIL-E-24269, Extinguisher, Fire, Carbon Dioxide, 15 Pound,
Portable, Permanent Shutoff, Navy Shipboard Use. There are no
fixed pipe CO2 systems for training purposes. Extinguishers
should be purchased as collateral equipment and stored in repair

a)
The 19F5, 19F5A, 21C12, and 21C12A trainers should
use a low pressure refrigerated, CO2 bulk storage tank system.
For other trainers, consideration should be given to using
either a low pressure refrigerated, CO2 bulk storage tank system
or high pressure 23 kg storage cylinders for recharging the
extinguishers.
b) The high pressure recharging system should consist
of 23 kg cylinders which are 1295 mm long by 215.9 mm in
diameter and weigh 72 kg when full. Cylinders contain CO2 gas at
5857 kPa at 21.1 degrees C. The recharging station should
consist of the following collateral equipment: tilt racks, a
scale, 220 V, single-phase motor and pump, fill hose, and
valves. For details, refer to Appendix A, Figure A-11. The 23
kg cylinders should be stored in a bulk storage area located
near the recharging area. The bulk storage area should be
suitable for storing 1 month's supply of cylinders plus 2 weeks
of empty cylinders. Sufficient access should be provided in the
bulk storage area for moving the cylinders.
