Firefighters Chase Down Acid Spill, Paint in the Arroyo and Mysterious Odor

Three incidents reported Tuesday in east Livermore made for a busy morning for firefighters:

• At 6:59 a.m. firefighters were sent to South Vasco Road near Industrial Way after a small container of an unknown substance fell onto the street. The contents of the gallon-sized container spilled, creating a vapor cloud, Battalion Chief Jeff Peters said. Northbound Vasco Road was temporarily shut down while a hazardous materials unit helped clean up the spill. The road reopened at 8:50 a.m. 
• At 10 a.m. two engines responded to a report of a white substance in the Arroyo Mocho Creek. Firefighters determined it to be water-based paint and spent nearly two hours trying to find the origin of the spill. The incident was turned over to the California Department of Fish and Game.
• At 10:10 a.m., firefighters were sent to a building at the corner of Las Positas and South Vasco roads for a report of a mysterious odor. The building was temporarily evacuated. "It ended up not being anything," Peters said.
