Dr M. H. Cass (ALP VIC) told Federal Parliament in March that an underwater snorkel on sale in Australia was lethal.
He asked the Prime Minister, Mr Gorton, to investigate the sale of the snorkel.
Mr Gorton agreed to make the inquiries.
The snorkel was described by Dr Cass as a long, underwater breathing snorkel with Ping-Pong valves.
He said that an 8 year old boy had drowned in three feet of water while using the snorkel.
