LSM-S-BE LIFT SYSTEM MEDIUM WITH SWIVEL BOX ENCLOSURE INTEGRATION CONSIDERATIONS General Mitigations: • Implement a hold to run/dead man switch operation. • Control methods should be located within direct line of site of the mechanism. High Risk - Crushing Crush hazard between the base • Implement password or key switch protected operation. panel and the cabinet top as the lift closes.
