Are markings, such as stenciling required on fire barriers, smoke barriers, and smoke partitions?

While NFPA 101 The Life Safety Code (2012) does not require hospitals to have markings or stenciling, fire barriers, smoke barriers, and smoke partitions are required by the International Building Code (IBC) beginning in the 2015 edition to be visually marked, usually by stenciling, on both sides of the barrier to indicate its rating.

This requirement is not retroactively applied; therefore older buildings may or may not have permanent markings, such as stenciling.

For more information reference the IBC (2018) 703.7.
