Early on a Thursday morning, an incident initially reported as an unknown explosion occurred at an Orlando Utilities Commission (OUC) substation at 129 Robinson St. in downtown Orlando. Orlando Fire and Police departments responded, with 16 fire units attending the scene and providing medical transports. Three OUC employees were taken to hospital. OUC's safety team conducted a preliminary investigation and identified the event as an arc flash, described as the light and heat produced by an arc fault, a type of electrical discharge resulting from a connection through air to ground or another voltage phase in an electrical system.

Police temporarily closed Garland Avenue and Robinson Street for the investigation before reopening them. OUC did not disclose the specific nature of the employees' injuries.

OUC's preliminary investigation identified the event as an arc fault causing an arc flash; no further technical cause was disclosed in the source.

  1. Substation arc flash from an arc fault can cause multiple worker injuries, so operators should enforce safe working distances and arc flash protective equipment.
  2. Initial reports of substation arc flashes may be logged as explosions, so utilities should issue rapid clarification to emergency services.
  3. Urban substations require pre-agreed protocols with police and fire for road closures during arc flash investigations.
