Electric Traction Lifts Without Motor Rooms. Also known as MRL Lifts (machine roomless lifts) (DoH Estates Alert)

The following Actions are required of NHS providers:

• All MRL lift installations should include some form of electrical standby power (probably UPS) to facilitate passenger rescue by ensuring electrically operated brakes can be lifted and/or power provided to drive a lift to the nearest landing. 
• All MRL lift installations should include a suitable system to monitor the condition of the UPS or battery and to raise alarms, where necessary.
• The lift installer should provide confirmation from the UPS manufacturer that the UPS is suitable for the environment where they are located (e.g. lift shaft, plant rooms, etc.) and in particular meets all Electromagnetic compatibility (EMC) requirements.
• Installation teams and healthcare providers should ensure that all emergency standby power and UPS equipment connected to an MRL lift are monitored by the healthcare premise Building Management System (BMS) or other suitable facility. 

For existing MRL lifts, healthcare providers should liaise with the lift installer to determine whether a link can be installed from the BMS/PC or suitable monitoring system to the lift UPS.

VIE (Vacuum insulated evaporator) Main Storage Vessel for Bulk Medical Oxygen Supply. (DoH Estates Alert)

There has been an uncontrolled release of liquid oxygen from a vacuum insulated evaporator (VIE) installed at an acute hospital in Wales. This resulted in the loss of approximately 7000 litres of liquid oxygen over a 45 minute period. The discharge was observed on CCTV cameras. If the CCTV had not been present the discharge may have gone unnoticed until the low level alarm activated for the system.
