Citizen app alerts reported on 13 October 2026 that firefighters were responding to two transformer explosions that caused power outages in the area. The alerts said firefighters were addressing smoke reported on Dumont Avenue after the explosions, and that a 911 caller had reported an unconfirmed incident at 499 Pennsylvania Avenue. Later alerts said firefighters had taped off the area, confirmed that surrounding exposures were safe, and notified the utility company.

The alerts do not state the city or country, the time of the incident, the transformer owner or operator, the equipment ratings, or whether anyone was hurt. The account rests on app alerts only and has not been confirmed by an official incident report.

Not reported. The alerts state only that the utility company was notified; no cause was given.

  1. Transformer failures can produce explosions, smoke and a wide outage, so operators should maintain clear exposure zones and isolation procedures for neighbouring equipment and property.
  2. Early public reports from 911 callers may be unconfirmed, so operators should coordinate with fire services and publish verified status as soon as it is known.
  3. Utilities should record the time, equipment involved and exposure checks promptly so that the cause can be investigated and confirmed later.
