The floatation device can be used by the wearer or hand it over to another person who might be in distress. The CO2 cartridge is replaceable thus this device can be used over and over again. With a pull at the tab, the device will be inflated in less than 5 seconds.
It is important to read and adhere to the instructions when checking and maintaining the inflation mechanism. Always do a visual check on the cartridge and the inflation bladder for any rips, tears and holes prior to usage.
