APTA SS-PS-004-99, Rev. 1 Edited 4-1-04 EXCEPTION--The maximum spacing of the marking materials may exceed 36 inches (91 cm) if the marking system is determined to provide equivalent visual delineation of the exit path. In stairways incandescent, EL, or LED marking material shall be applied either as a continuous strip applied on the partitions of at least one side of the stairs or as intermittent strips applied to the treads of each step. When the marking material is applied to the stairway partitions, the marking shall be applied as a continuous strip extending from the lowest to the highest step. The strip shall be located no higher on the partition than 18 inches (45.7 cm) above the plane of the stair nosing. When the marking material is applied to the stairway treads it shall extend across the full width of each tread near the step nosing. 5.2.2 Other active marking methods In lieu of, or in addition to, HPPL materials, electrically illuminated marking methods using lighting fixtures may be employed as LLEPM material on all cars. Fixtures may be mounted on partitions or seat pedestals. These marking systems may include incandescent or fluorescent lighting fixtures. The lighting fixtures must be independent of the car’s normal and emergency lighting system and be operational for a period of 1.5 hours after all normal and emergency lighting has ceased operating. The partition or pedestal-mounted internally illuminated lighting fixtures may be applied at a height of up to 18 inches (45.7 cm) above the floor on at least one side of the aisle/passageway and shall be applied at intervals not to exceed 36 inches (91 cm) between fixtures. In stairways, partition-mounted lighting fixtures shall be installed on at least one side of the stairway. A lighting fixture shall be installed at each step tread and be located no more than 18 inches (45.7 cm) above the tread. The illuminance value of the lighting fixtures shall provide an average illumination value of at least 0.1 fc measured and averaged at intervals of 30 inches (76 cm) or less along the center of the aisle, passageway, or stairs. The measurements shall be taken 1.5 hours after normal lighting has ceased operating with all ambient light obscured. The spacing between the corner of a change in direction of the exit path and the marking material/fixture shall not exceed 4 inches (10 cm). EXCEPTION--The maximum spacing of the marking materials may exceed 36 inches (91 cm) if the marking system is determined to provide equivalent visual delineation of the exit path. 4.11 Volume VI - Passenger System
5.3 LLEPM exit door markings 4.12 APTA SS-PS-004-99, Rev. 1 Edited 4-1-04 All primary exit doors shall be clearly delineated with HPPL marking material. A minimum of 1-inch (2.54 cm) wide strips shall be applied to both sides of the exit doors or door frames and shall extend from the floor to a minimum height of 12 inches (30 cm) above the floor. Additionally each door handle, latch, or operating button shall be identified using one of the following two methods: 1) Each door handle, latch, or operating button shall be identifiable using 1 inch (2.54 cm) wide outline stripping around the perimeter of the opening device. 2) Each door handle, latch, or operating button shall be identifiable using an area wide pad that is no less than 6 square inches (39 sq. cm) applied to the door or door frame directly behind the handle or latch. 5.4 LLEPM exit door sign All primary exit doors shall be clearly marked with an exit sign located on or immediately adjacent to each door that is no more than 18 inches (45.7 cm) above the floor as measured from the floor to the top of the sign. The LLEPM door exit sign may be HPPL material, incandescent, fluorescent, EL, or LED fixtures. The text and color requirements shall be in compliance with APTA SS-PS-002-98, Rev. 2 3 relative to exit door markings. 6. Material safety Materials used in the manufacture of LLEPM products shall not contain radioactive or toxic materials. 7. System reliability All LLEPM systems shall be designed so that the exit path shall not be rendered indistinguishable due to the failure of any single HPPL material segment, lighting strip, light fixture, or battery. 8. Operating conditions All LLEPM systems shall be designed to operate without failure under the conditions typically found in passenger rail equipment. These conditions shall include expected mechanical vibrations and shock, electromagnetic interference, and other criteria as identified in 49 CFR, Part 238, Passenger Equipment Safety Standards. 3 For references in Italics, see Section 2.
