What happened

An electricity substation off West Durlston Lane in Swanage was reported to have exploded twice over a weekend in May 2023. Two crews from Swanage Fire Station attended after a call at 4.33pm. The fire was already out on arrival. The area was cordoned off while crews made the site safe, and the incident was handed to the electricity board. It was understood that no one was injured.

Lessons learned

  1. After a reported substation explosion, treat the site as live until the network operator has made it safe.
  2. A fire that is out on arrival still needs a cordon and a formal handover to electricity engineers.
  3. Record the call time and the arrival of engineers so later reports do not confuse the incident date with the publication date.
