The NSW Fire Commissioner has said Australia's most common smoke alarm should be banned.

A two-year-old died after she got stuck in the cord of a tangled window blind which strangled her, while she played hide and seek with her older brother.
Danielle Hudson, 28, found her daughter Sophie Allen hanging with the beaded cord around her neck in her bedroom when she went to find her, after her four-year-old son Jayden said his sister was stuck.
Despite efforts to revive her, Sophie was taken to hospital and put in an induced coma. The two year old died on Saturday, five days after her mother found her trapped in the cord.
Miss Hudson, of Sunderland, said: “My son came in and said 'Sophie's stuck' and pointed at the cupboard. I didn't understand what he meant and just thought she was hiding. "Then he came back and said it again. I walked over to the window and saw a shadow behind the curtain.
