  "abstract": "This disclosure describes a mobile racking system configured to manage the kinetic energy of closing aisles, addressing the fundamental hazard of personnel entrapment. The system employs a specific aisle opening sequence and movement control strategy to limit the maximum kinetic energy achievable by any closing aisle section. This approach complements presence detection arrangements, which may have inherent coverage gaps, by ensuring that even in the event of an undetected presence, the potential impact energy remains below a predetermined threshold. The system also incorporates a manual release mechanism to facilitate egress from a partially or fully closed aisle.",
