Health Minister Dr S Subramaniam said the electrical system at Sultanah Aminah Hospital (HSA) in Johor Baru will be inspected, after it was hit by a second incident in 48 hours.

"The engineering division, Jabatan Bomba, and the concessionaires, are conducting a thorough inspection of the electrical system and other related appliances," said Subramaniam in a statement tonight.

Earlier today, smoke was seen billowing from the operating theatre of the hospital's West Block.

The smoke originated from a socket that came into contact with water, following efforts to clean the area in the wake of yesterday’s fire which killed six people in the Intensive Care Unit (ICU).
