UPDATE, Monday 8.10am: THE health service has said there will be a "full investigation" after a wild storm damaged Lismore Base Hospital yesterday.
WorkCover is expected to arrive at the hospital this morning to start investigations.
Executive Director of the Richmond Clarence Health Service Group, Lynne Weir, said scaffolding attached to the redevelopment of the hospital collapsed onto the obstetric area of the hospital late yesterday afternoon.
"Nineteen people were inside at the time, five mothers and their babies, two staff and seven visitors," she said.
"They were escorted by emergency services to another part of the hospital shortly after the incident.
"One nurse was treated for a minor back injury.
"The hospital remains operational.
"The emergency department was not affected and has continued to operate as normal.
"An exclusion zone had been set up around the site to ensure there is no further risk to patients, staff or the public.
"The construction site will remain closed until a full investigation has been undertaken and engineers have determined the site safe."
FIVE babies and their mums were evacuated when the maternity ward of the Lismore Base Hospital collapsed during the recent rain storms just after 4pm today.

There are reports of the building filling with water and electrical wires hanging from the ceiling.
It was also reported 17 people including five babies and five mums were evacuated from the building.
The scene has been attended by HAZMAT and rescue teams from Ballina and as far as Woodburn.
