Firefighters and a hazmat team have been dispatched to an Ikea warehouse in Frederickson, according to Central Pierce Fire & Rescue spokesman Brian Levings.
A person operating a forklift inside a shipping container ran over something that kicked up a dust that made the person dizzy and sick, Levings said.
The hazmat crew was dispatched and believes the substance to be battery acid and ice melt.
The warehouse is at 5604 196th St. E. in Frederickson.
