Employees at an east side business believe the warehouse-style building was struck by lightning Wednesday afternoon, Madison fire officials said.
Employees said lights flickered and they could see smoke just after they saw a flash at a business in the 1900 block of East Johnson Street.
Crews responded to the warehouse-style building around 3:45 p.m. and found a light haze and a smell of burning rubber in the building, according to the release. There were no apparent signs of fire, and a bank of transformers was not damaged.
Firefighters found an electric meter that had blown in the electrical room, and MG&E crews came to service the meter, officials said.
The smoke in the building dissipated on its own, and no other damage or fire was found, according to the release.
