A lockout cover for restricting access to ports, valves, regulators and/or gauges shielded by a halo handling ring on top of a Dewar bottle. The lockout cover includes a cap seatable on the halo ring. A hatch on a side of the cap can be pivoted between an open position to allow access to the ports, valves, regulators and gauges, and a closed position to allow locking the cap to the halo ring to block access to the ports, valves, regulators and gauges.
