Fire officials are investigating after an explosion inside an office building in Phoenix on Saturday morning.
Phoenix Fire crews responded to the call of the explosion at a telecommuting business off Peoria Avenue near I-17.
An electrical system in the basement was reportedly the source of the explosion. The pressure of the explosion broke several windows in the building.
Officials say dozens of people were inside the building at the time, but fortunately everyone got out safely.
Fire officials say it's a good reminder to practice workplace safety.
Officials will be on scene for some time to ensure the safety of the building once power is restored, but said the explosion appears to be an isolated incident.
