What happened
On Friday, reported as 30 June 2023, a fire broke out inside the Warner Bros. studio lot in Burbank, California, during a studio tour, following an electrical explosion. Burbank Fire Department received its first call at 1:38 p.m. and the fire was reported out by 2:08 p.m. Fire officials said no buildings were damaged and there were no injuries. Smoke was visible over Burbank and Toluca Lake. A Burbank Fire Department battalion chief told Deadline that it was a transformer fire, but fire investigators had not released a definitive determination of the cause at the time of reporting.
A source described as a Warners insider told the Hollywood Reporter that the fire was considered an accident and was not believed to be deliberate. A Twitter user who said they felt the explosion described a loud bang and said their power flickered.
Contributing factors
Not reported. Fire investigators had not released a definitive determination of cause at the time of reporting.
Lessons learned
- Transformers on commercial sites can fail with an explosive electrical event that spreads smoke over a wide area, so fire response plans should cover distribution transformers as well as generation assets.
- Visitor tours and public areas near electrical plant need clear procedures for sheltering or evacuating people when an electrical fire occurs.
- Operators should keep fire service contact details and site access information current so responding crews can reach electrical equipment quickly, as the fire reported here was brought under control within 30 minutes.
