Cause of death

Crush injuries (chest and abdominal injuries and chest compression) sustained in a wastepaper compactor accident

AI-generated summary

Daniel Thomas Knight, aged 43, died from crush injuries sustained while attempting to clear a blockage in a wastepaper compactor (model TCU 660) at a printing business. The compactor had never functioned correctly due to missing safety components (rotary valve, airlock, or air balancing fan), requiring frequent unblocking. Despite being told not to touch the machine and despite the air and power being switched off, both were mysteriously switched back on. Mr Knight entered the compactor with a rake to clear a blockage and accidentally contacted the left-hand compacting ram, which retracted and then extended, trapping him between both rams under 5 kilonewton force. Multiple safety failures contributed: inadequate machinery design and installation, no staff training on isolation procedures, failure to dissipate stored energy, and lack of proper guarding and interlocks. Prompt recognition and CPR attempted, but injuries were fatal.
