The Health and Safety Executive (HSE) has announced it will prosecute Wessex Water for criminal offences under the Health and Safety at Work etc. Act, following a deadly explosion at the company's Avonmouth treatment site near Bristol in December 2020 that killed four workers.
Victims and Incident Details
The explosion claimed the lives of Luke Wheaton, 16, Ray White, 57, Brian Vickery, 63, and Mike James, 64. The four workers, including an apprentice, were performing welding on the roof of an anaerobic digester silo when a spark ignited gas inside the structure, causing a catastrophic blast.
Investigation and Prosecution Decision
Initially, Avon & Somerset Police led a criminal investigation into the incident. In July 2024, they dropped the case, stating that the evidence gathered did "not reach the extremely high threshold to prosecute" Wessex Water or any individual for corporate manslaughter. The HSE then took over the investigation and has now confirmed it will bring charges.
An HSE spokesperson stated: "Following an investigation by the Health and Safety Executive into an incident at Avonmouth on 3 December 2020, which resulted in the deaths of four workers, our Legal Services Division has taken the decision to authorise criminal charges against Wessex Water, for offences under the Health and Safety at Work etc. Act."
Company Response
Wessex Water, owned by Malaysian firm YTL, confirmed it had been informed of the impending charges. A company spokesperson said: "The HSE has informed us of its decision to prosecute. We will always remember Brian Vickery, Ray White, Luke Wheaton and Mike James. Our thoughts are with their families, friends and colleagues."
Family and Legacy
In the aftermath of the tragedy, the grieving families paid tribute to their loved ones and requested privacy. They have since engaged in fundraising and other projects to honour the deceased and create a lasting legacy, refraining from public comment on the ongoing investigation.
