A large explosion occurred on the afternoon of July 24 at an industrial site near Rettendon, Essex, causing significant damage and prompting an extensive emergency response. The blast was reportedly heard up to 12 miles away, with some residents in nearby areas such as East Hanningfield and Rettendon describing a loud boom shortly before 6 p.m. The explosion sparked a fire that produced thick black smoke visible across the county.

Emergency services deployed more than 100 firefighters to the scene on Southend Road, approximately five miles south of Chelmsford, to contain and extinguish the blaze. Essex Fire and Rescue Service advised local residents to keep their windows and doors closed and urged people to avoid travelling to the affected area while operations continued.

The incident reportedly involved the explosion of fertiliser stored at the site, which contributed to the fire and destruction of some businesses operating on the farm premises. The force of the blast caused vibration and shaking in surrounding homes. While firefighters worked to bring the fire under control, there have been no confirmed reports of injuries as of the latest updates.

Authorities continue to investigate the cause of the explosion and assess the full extent of the damage to the industrial unit and neighbouring properties. Meanwhile, residents in the vicinity remain advised to exercise caution and follow instructions from emergency services as the situation develops.
