NRS Self Inflating PFD CO2 Green Arming Pin

NRS inflatable PFDs use this Green Arming Pin as an indicator that the CO2 inflation cylinder is unused and ready to inflate the PFD when needed. When the cylinder is punctured, the Green Pin breaks and falls away. So that it doesn't interfere with activation of the inflation mechanism, the Green Pin is fairly fragile. Store it so that it doesn't get damaged in transport.
