The Harloff Malignant Hyperthermia Cart Breakaway Lock Bars (MH-BA Series) are specialized security retrofit assemblies and locking bar options engineered specifically for Harloff Malignant Hyperthermia (MH) medical carts and integrated cold-storage refrigerators. Malignant hyperthermia protocols demand instantaneous, single-motion access to critical chilled medication (such as Dantrolene) and emergency cooling supplies during acute hypermetabolic crises. These heavy-duty breakaway lock bars provide physical supply security while holding single-use plastic breakaway seals that break cleanly upon activation, ensuring immediate access while delivering clear visual verification of cart and refrigerator integrity. Available for both factory installation and field retrofit on MH series drawer configurations and cooling units, these assemblies maintain full compliance with hospital pharmacy security standards and emergency clinical guidelines.
