(CNN) London – A union representing workers on the rig warned there was an “urgent need” to stop the leak, that sprang Sunday.
“If the gas cloud somehow finds an ignition source, we could be looking at complete destruction,” said RMT union official Jake Molloy.
“This is an unprecedented situation and we really are in the realms of the unknown,” Molloy said of the leak from the Elgin platform in the North Sea, about 150 miles (240km) east of the Scottish city of Aberdeen.
