MALDEN, MASS. (WHDH) - A major mess in Malden on Tuesday after a fire suppression system accidentally went off and coated a gas station in white powder.

She went to the emergency room to have saline put on her face to clear off the chemicals. She said the powder irritated her kind and lungs.

It’s unclear what caused the system to go off.
