The emergency room is accepting patients, MultiCare Health System spokeswoman Marce Edwards said.

INITIAL POST: The Emergency Room at Good Samaritan Hospital in Puyallup is shut down for several hours while crews handle a hazardous material spill.
It appears one of the employees poured one of the drain cleaners down the sink and had a chemical reaction with something already in the sink, Central Pierce Deputy Fire Marshal Guy Overby said.
The incident started about 10 a.m.
Six hospital workers, one patient and a family member of the patient reported breathing problems or eye irritation and are being decontaminated.
Crews will be conducting air quality tests before allowing people back inside the Emergency Room, Overby said.
Puyallup police said they are closing Third Street Southeast between 15th Avenue Southeast and 14th Avenue Southeast. The hospital is located at 401 15th Avenue Southeast.
