Sian Hammond was a consultant at Weatherfield General where an unconscious Claire Peacock was admitted following a house fire at 4 Coronation Street in May 2007. Suffering from the effects of smoke inhalation, the consultant advised her staff that an anaesthetist needed to be paged and a chest x-ray organised as she was worried about Claire's airway being compromised. She informed anxiously awaiting Eileen Grimshaw and Violet Wilson - who had accompanied Claire in the ambulance - that Claire had been transferred to the Intensive Care unit. The consultant was also at Claire's bedside along with Eileen and Violet when she regained consciousness.
