While it brought Buckman undone, the fast opening heat carried her two Australian teammates, Melissa Duncan and Kaila McKnight, into the final as fastest qualifiers.
The incident did not appear to interrupt Van Dalen's performance.
Meanwhile, the pain of the past four years faded for Hamblin as she produced another solid performance at the Commonwealth Games.
Hamblin has endured a torrid time since double silver in Delhi, with a spate of injury problems causing her to question her future in middle-distance running.
But all the hurt would have been forgotten, for a few minutes at least, as Hamblin qualified second-fastest for the final of the 1500m at Glasgow's Hampden Park.
Set to run at the London Olympics, Hamblin suffered heel pain, eventually determined to be bone spurs, that kept her from the Games.
A torn Achilles came the same year, but now the 26-year-old is back and ready to attempt a repeat of her feats in Delhi, with heats in the 800m set for tomorrow.
Van Dalen gets another shot at gold when she contests the 5000m at the weekend.
