This newsreel shows the devastating consequences of a fatal blast at a Castleford chemical plant.
In July 1930, 13 people were killed and 32 injured when part of the Hickson and Welch factory exploded. The blast left 300 houses nearby uninhabitable.
The British Pathe film captures images of the damage caused by the accident and the efforts of the fire service to make the area safe. Residents are also shown moving furniture out of destroyed homes.
Sadly the factory, which later became C6 Solutions, was the site of another deadly blast in 1992, when five workers were killed and 200 hurt. The plant closed for good in 2005.
