A cancer ward in Swansea's Singleton Hospital will remain closed for up to three months following fire damage.
Patients and staff were evacuated from ward 12 on Monday 25 March after a fire broke out.
ABM University Health Board says all 36 patients on the oncology ward were evacuated safely, as well as staff, and no one was injured.
Following assessment of damage caused, the hospital has now warned the ward could be out of action for up to 12 weeks.
Service Director at the hospital, Jan Worthing, thanked staff for their hard work.
An investigation into the fire found no further action is required but the hospital is still feeling a knock on effect.
People are being urged to "think carefully" before travelling to Accident & Emergency Departments in the area.
Andy Macnab from Morriston's Emergency Department said: “We know from experience that our local community can be extremely helpful at times like this and would really appreciate their continued assistance in not using the ED for non-emergency problems.”
