【国外标准】 Standard Specification for Multi-Story Building External Evacuation Platform Rescue Systems

This specification covers the specifications, safety requirements, performance, design, practices, marking instructions and test methods for multi-story building external evacuation platform rescue systems (PRS) for emergency escape of persons who cannot use the normal means of egress to a safe area and for vertical transport of emergency responders. This specification is applicable only to PRSs that are permanently installed, designed for multi-cycle and repetitive use, and where descent is controlled to limit speed before arrival at a floor or landing zone. Conversely, this specification does not cover platform devices that are used primarily for purposes other than emergency evacuation and/or access, helicopters or other flying platforms, a PRS utilizing platforms that can be transported to or between buildings during operations, and a PRS using driving methods other than positive drive as drum and ropes.1.1 This specification covers the specifications, safety requirements, performance, design, practices, marking instructions and test methods for Multi-Story Building External Evacuation Platform Rescue Systems (PRS) for emergency escape of persons who cannot use the normal means of egress to a safe area and for transport of emergency responders vertically.1.2 This specification is applicable only to PRSs:1.2.1 Permanently installed;1.2.2 Designed for multi-cycle and repetitive use; and1.2.3 Where descent is controlled to limit speed before arrival at a floor or landing zone.1.3 This specification does not cover:1.3.1 Platform devices that are used primarily for purposes other than emergency evacuation or access, or both;1.3.2 Helicopters or other flying platforms;1.3.3 Any other devices covered under/within ASME A17.1;1.3.4 A PRS utilizing platform(s) that can be transported to or between buildings during operations; and1.3.5 A PRS using driving methods other than positive drive as drum and ropes.1.4 Operation of a PRS is limited to trained and authorized operators.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5.1 Exception—In 5.2.1 and 5.2.2, inch-pound units are provided in parentheses after the SI units for information only.1.6 Table of Contents:   Section 1Referenced Documents 2Terminology 3Building Interface Requirements and Installation 4Environmental Conditions 5Fire and Smoke Protection 6Material Requirements 7Structural, Mechanical and Stability Calculations 8Mechanical and Physical Properties 9Buffers and Guides 10Suspension Wire Rope and Wire Rope Connections 11Hoisting Machines and Pulleys 12Means to Prevent Falling of the Platform(s) 13Electrical Power Requirements 14Operation, Control and Communication 15Accompanying Documents 16Markings, Warnings and Operating Instructions 17Verification of Safety Requirements 18Quality Assurance 19Maintenance 20Keywords 21Type Tests Annex A1Tests and Verifications Before First Use Annex A2Periodic Verifications Annex A3PRS Utilization Procedures Annex A4Rationale Statement Appendix X11.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.
