The most damage was done on June 1, 2008 when a three alarm fire broke out on the back lot of Universal Studios. The fire started when a worker was using a blowtorch to warm asphalt shingles being applied to a facade. The Los Angeles County Fire Department had reported that Brownstone Street, New York Street, New England Street, the King Kong attraction, some structures that make up Courthouse Square, and the Video Vault had burned down (not to be confused with the actual Film Vault; the Video Vault contains duplicates of Universal's film library). Aerial news footage captured the Courthouse building surviving fire for the third time in its history, with only the west side of it being slightly charred. Over 516 firefighters from various local fire departments, as well as two helicopters dropping water, had responded to the fire. Fourteen firefighters and three Los Angeles County sheriffs' deputies sustained minor injuries. The fire was put out after twelve hours, during which time firefighters encountered low water pressure.
