Investigation and inquest
On 2 December 2021, one of my assistant coroners, Sarah Bourke, commenced an investigation into the death of Sean O’Connor aged 34 years. The investigation concluded at the end of the inquest on 1 May 2024. The jury made a determination at inquest of death by accident.
Circumstances of the death
On 24 November 2021, shortly after 10am, Mr O’Connor was electrocuted as a result of contact with a heat pump flow switch terminal, during the course of work at Columbus House 7 Westferry Circus, London. He was a Mitsubishi employee changing the flow switch.
His medical cause of death was:
1a electrocution.
Coroner’s concerns
I heard evidence at inquest that, as he was regarded as a lone worker, Sean O’Connor could and, according to the risk assessment method statement (RAMS), should have asked a CWML colleague to come to check on him during the day. He did not ask for such a check and, although a CWML employee thought of doing so, that person was busy and so did not.
Whilst such a check is likely to have taken place too late in the day to have changed the outcome for Mr O’Connor, that might be different for another lone worker.
Several witnesses gave evidence that discussions take place with every worker coming on site as a matter of routine, covering such matters as where the worker is meant to be located, the exact nature of the job and so forth. The CWML director who gave evidence at inquest agreed with me that it would be a straight forward matter to include within that as a point always for brief discussion, whether any checks are required during the day. In this way, if the operative forgets to ask, the discussion can act as a reminder.
