SAN DIEGO (KGTV) -- The San Diego Fire Department and Bomb Squad responded to a hazmat situation in Kearny Mesa Monday.
According to the department, the incident started just before 3 p.m. near the intersection of Balboa Avenue and Ponderosa Avenue near Montgomery-Gibbs Executive Airport.
According to the San Diego Fire-Rescue Department, workers at Senior Aerospace Jet Products routinely put titanium shavings in barrels.
Monday afternoon, one of the barrels, a 55-gallon drum, began to get hot and started expanding.
Firefighters arrived at the business and poured water on top of the barrel to cool the contents after evacuating the building.
The bomb squad and hazmat technicians were also called to the scene and, after opening the barrel, say the titanium was reacting with another chemical.
Shortly before 7 p.m., the area was declared safe and the barrel turned over to the company for proper disposal.
