The gas leak was caused by a pool chemical mix-up at about 9am Australian time, the trust managers said in an announcement to the Singapore Exchange. The hotel has since resumed operations.

The hotel is managed by Accor, which is investigating the matter and providing assistance to employees and guests, the trust managers said.
