Can I assume this means GFCI?

422.41 Cord-and-Plug-Connected Appliances Subject to
Immersion. Cord-and-plug-connected portable, freestanding
hydromassage units and hand-held hair dryers shall be constructed
to provide protection for personnel against electrocution
when immersed while in the ?on? or ?off? position.

Yes, there are also a couple of other things built into these "appliances".
The hand book has a good explanation. (2011)

Yes, here's the commentary...

Although receptacles in bathrooms of dwelling units have been required to be protected by ground-fault circuit interrupters since the 1975 edition of the Code, many receptacles in existing bathrooms are not so protected. Cord-and-plug-connected appliances such as hand-held hair dryers and curling irons, which can and have accidentally fallen into bathtubs, causing fatalities, are required to be provided with some form of protective device that is part of the appliance. Three types of protectors comply with this requirement:

1. Appliance-leakage circuit interrupters (ALCIs)

2. Immersion-detector circuit interrupters (IDCIs)

3. Ground-fault circuit interrupters (GFCIs)

ALCIs de-energize the supply to the appliance when leakage current exceeds a predetermined value. IDCIs de-energize the supply when a liquid causes a conductive path between a live part and a sensor, and GFCIs de-energize the supply when the current to ground exceeds a predetermined value.
