What components are likely attached to an inflatable type PFD?

Inflatable personal flotation devices (PFDs) are designed to provide buoyancy when needed while remaining compact and easy to store when not in use. The key components that are integral to the function of an inflatable PFD are the buoyant flotation and the inflation chamber.

The inflation chamber is filled with air when the device is activated, providing buoyancy to keep the wearer afloat. This inflation method allows the PFD to have a lower profile and be more comfortable when not in use compared to traditional foam PFDs. The buoyant flotation component ensures that once inflated, the device will provide enough lift to keep the wearer above water, which is essential for safety in emergency situations.

While other options list various accessories that can enhance safety, they do not represent the primary components specifically associated with inflatable PFDs, which focus on buoyancy and inflation mechanisms.
