On 23 February 2016, a large section of the former boiler house at Didcot A power station collapsed while the building was being prepared for demolition. One person was killed outright and three people were listed as missing presumed dead. Four or five people were injured, three seriously. Additionally, around 50 people were treated for dust inhalation. The rubble from the collapse was high and unstable, which along with the instability of the remaining half of the building hampered search efforts.
