Introduction 4.1 APTA SS-PS-004-99, Rev. 1 Edited 4-1-04 (This introduction is not a part of APTA SS-PS-004-99, Rev. 1, Standard for Low- Location Exit Path Marking.) Review of past passenger rail accidents involving passenger and train crew emergency evacuation has indicated that both passengers and emergency responders lacked sufficient information necessary for expedient emergency egress and access due to the absence of clear markings and instructions. The lack of adequate signage in conjunction with lighting system failures and/or low levels of illumination during these accidents were cited as a cause for confusion and as a contributing factor to the injuries and casualties that resulted. The National Transportation Safety Board (NTSB) made the following recommendation to the Federal Railroad Administration (FRA) in National Transportation Safety Board Recommendation to Federal Railroad Administration, FRA R-97-17 after investigation of a recent passenger train accident: “Issue interim standards for the use of luminescent material, retroreflective material, or both to mark all interior and exterior emergency exits in all passenger cars as soon as possible and incorporate the interim standards into minimum car standards.” FRA issued a final rule revising existing glazing standards contained in 49 CFR, Part 223 and established minimum standards for emergency preparedness (see 49 CFR, Part 239). The FRA regulations require that minimum levels of emergency lighting be provided near doors and along the aisles be for new cars. In addition, for both new and existing cars, the interior location of each passenger car door used for emergency egress must be marked and be conspicuously visible by the use of lighting and/or luminescent marking. Each door control release mechanism must be marked on the interior and exterior with clearly visible and legible instructions. The interior location of emergency exit windows must also be clearly visible by the use of luminescent material and instructions for their use must be also be provided. If exterior window access points are provided to emergency responders, clear and conspicuous markings and instructions must be provided. This standard establishes requirements for LLEPM which will provide visual guidance for emergency rail car evacuation when smoke conditions obscure overhead emergency lighting or when failure of the emergency lighting system has occurred This standard, taken together with the American Public Transportation Association (APTA) APTA SS-E-013-99, Standard for Emergency Lighting System Design for Passenger Cars, and APTA SS PS-002-98, Rev 2, Standard for Emergency Signage for Egress/Access of Passenger Rail Equipment 1 , provides a systems approach to locate, reach, and operate emergency exits to ensure the safe evacuation of passengers and crewmembers in the event of an emergency. Railroads and car builders should carefully consider the options available to meet emergency evacuation requirements presented in these three standards. 1 For references in Italics, see Section 2 of this Standard. Volume VI - Passenger System
APTA SS-PS-004-99, Rev. 1 Edited 4-1-04 This revision of the Standard contains a reorganized section 1 (to include scope); renumbered Reference section (now 2) and addition of 49 CFR regulations, and ASTM and UL standards as references. One definition (marking) was added and abbreviations and acronyms are now included in Section 3. Section 6 headings were revised, material safety is now a separate section 7, and the remaining sections are renumbered. In addition, the bibliography was moved to Annex A, and the information formerly contained in Annex A was expanded upon (now included in Annex D), and two new annexes were added to provide railroads with extensive guidance for ensuring that the passive LLEPM material required by this standard provides the minimum brightness specified herein. 4.2 Volume VI - Passenger System
