The unique type of survival suit is the inflatable immersion suit. Inflatable immersion suits are recently manufactured.
Its buoyancy stops the wearer from sinking. It helps to keep them floating face up. The immersion suit is waterproof. It shields the wearer from cold water-body contact.
Furthermore, it is insulated to offer protection from fire. It’s recommended to wear it before inflation.
Once the inflatable immersion suit has been put on, the wearer activates firing handles on compressed carbon dioxide cartridges.
It punctures the cartridges and rapidly inflates the suit. This results in a highly buoyant and rigid shape suit. It also offers very high thermal retention properties.
Like the inflatable boat, the inflatable immersion suit also possesses all precautionary properties. The suit has two or more vesicles in case it is ruptured, and the gas is discharged, another vesicle is available to be used.
