On 20 September 2017, two employees of were using a grinder to cut and replace pipework at the top of an 11-metre (40’) high metal tank containing waste slurry.
They were not using harnesses.
Sparks from the grinder ignited flammable gasses causing the tank to explode. The slurry vessel was airborne for 9 seconds and came down approximately 100’ from its original location.
Footage of the explosion captured by CCTV has now been released.
