Firefighters were called to Metalworking Fluid Additives Manufacturing Company on 47th Avenue south of Van Buren Street at about 5 a.m. Friday.  An employee reporting for work noticed a light haze inside the building, as well as a strange smell.  No fire was found, but the building was evacuated while firefighters went in to determine what caused the haze and the odor.  Story and video from azfamily.com
