A man believed to be threatening to ignite a barbecue gas bottle has shut down a Gold Coast street for 11 hours.

The man called police from a house on Hart Street, Upper Coomera, on Wednesday, making threats to harm himself.

At 7pm (AEST) officers declared an emergency situation, evacuating homes on Hart Street and several surrounding streets.

The emergency area was scaled back to just Hart Street about 5.30am on Thursday, but police negotiators were still talking to the man at 6am.

It is believed he is alone.
