Firefighters used a CO2 canister to extinguish an underground fire in Palo Alto Monday morning, Jan. 28, a battalion chief said.
Crews responded to a report of flames coming out of a manhole grate in the 1400 block of Dana Avenue at about 4:15 a.m., Battalion Chief Niles Broussard said. The firefighters isolated the blaze to an underground electrical vault and used CO2 to extinguish it, Broussard said.
Broussard said flames were reaching six to eight inches above the manhole grate. The blaze was extinguished at about 4:45 a.m., he said. No injuries were reported. The fire department is investigating the cause of the fire.
Residents in nearby homes that were awake were advised to shelter in place as crews put out the fire, he said.
As of 6:15 a.m., city of Palo Alto utility crews were at the scene to fix the electrical equipment, which included a failed transformer, city Communications Manager Linda Clerkson said in a statement. Electrical service was restored to 538 customers. Twenty-one additional customers form this outage were to remain without power until 4 p.m.
At about 8 a.m., utilities customers began experiencing brown-outs in the area of Center Street from Pittman to Dana avenues because of equipment damage caused by the fire, Clerkson said.
Approximately 200 customers were affected by this outage. Additional utilities crews responded and performed line patrols and cable testing for the new outage, she said. Power was restored to 150 customers, and the final 50 customers received power by 12:50 p.m.
