What triggers inflation of the raft?

Inflation is triggered by releasing the stored CO2 gas from the cylinder through a burst disc when you pull the painter-operating cord. The tug activates a mechanism that punctures the disc and opens the valve, allowing gas to rush into the raft and inflate it rapidly. Manual pumping would be much too slow for quick deployment, a solar inflator isn’t a standard feature on liferafts, and the burst disc by itself isn’t the trigger—it's the safety seal that’s ruptured by pulling the painter cord to release the gas.
