What must the rescue swimmer wear?

The appropriate attire for a rescue swimmer is a wetsuit and a personal flotation device (PFD). The wetsuit is essential for thermal protection, as rescue missions often take place in cold or challenging water conditions. It allows the swimmer to maintain body heat while also providing some buoyancy. The PFD is a crucial safety measure, ensuring that the swimmer remains afloat in case they tire or experience difficulties in the water.

While helmets, life jackets, dry suits, and fins serve important purposes in various marine and rescue operations, they are not the standard requirement for a rescue swimmer's attire during typical missions. The combination of wetsuit and PFD effectively balances safety, mobility, and thermal protection, making it the best choice for a rescue swimmer's needs in the field.
