The 5B male medical ward at Hospital Raja Permaisuri Bainun was vacated following a short circuit last night, Bernama reported.

Health director-general Dr Noor Hisham Abdullah said the short circuit which happened at 11.16pm, originated from a wall plug beside the beds.

He said none of the patients or hospital staff were injured in the incident.

"The hospital has moved the patients to another ward while the wiring and safety are being checked," he told the newswire.

This comes after a fire at Hospital Sultanah Aminah (HSA) in Johor Baru killed six people last month.

The hospital was evacuated again the next day after a short circuit occurred in the operating theatre.

Three personnel received treatment for smoke inhalation.

The main block of the hospital was closed pending inspection and repairs.
