Steps taken against recurrence of chlorine mishap at Superdrome

11/3/95

Steps have been taken to minimise the risk of a repetition of last week's chlorine mishap at Perth's Superdrome, Sport and Recreation Minister Norman Moore said today.

"The investigations have shown that a safety control mechanism failed while repairs were being performed," Mr Moore said.

"The failure allowed a sudden build-up of sodium hypochlorite in the pumping system to spill into the main pool when the main circulating pump was switched back on, after repairs had been completed.

"It was an unforseen mechanical failure and the Superdrome has taken steps to minimise the risk of any such malfunction in the future.

"The safety mechanism which failed has been updated and is now fully operative.  Furthermore, a backup safety system using a pressure sensing system has been installed.

"In effect, there are now two mechanical safety systems which should prevent a recurrence of last week's mishap.

"The Superdrome has also taken steps to make its operating procedures even safer.  After a revision of procedures this week it has been decided that the main circulating pump will not be switched off or on while people are in the pool. 

"The safety of the patrons and staff of the Superdrome is of great importance and until last week's mishap the venue's safety record was perfect.

"With an average of 350,000 people using the pool each year, the safety record is one we are all proud of.

"I am also very impressed with the efficient and effective manner in which the Superdrome's staff handled the incident."
