Q. Where do I find photoluminescent markings in public transportation?

A. The American Public Transportation Association (APTA) has two standards that require photoluminescent material on passenger trains: APTA SS-PS-004-99, Rev. 2–Standard for Low-Location Exit Path Marking, requires outlining of the path to the exit doors either on the passenger rail car floor or seats in floor proximity. APTA SS-PS-002-98, Rev. 3, is the Standard for Emergency Signage for Egress out of Passenger Rail Equipment. You also may find photoluminescent floor proximity lighting on many airplanes these days. Flight attendants point out such low-location lighting during pre-flight safety briefings.
