INVESTIGATION and INQUEST

On 11 September 2020 I commenced an investigation into the death of Jean DYE aged 77.
The investigation concluded at the end of the inquest on 02 July 2025. The conclusion of
the inquest was that:
Jean Dye died on 7 September 2020 at Scunthorpe General Hospital as a consequence of
an iatrogenic artery dissection which occurred during Percutaneous Coronary Intervention
to treat underlying cardiac disease. That was a rare but recognised complication of the
procedure. Once the dissection was identified there was a limited opportunity to provide the
necessary remedial treatment by the deployment of cardiac stents. Coincidentally at that
moment there was a sudden and unexpected failure of electrical power within the treatment
room which persisted for approximately 10 minutes. Save that it resulted from an
activation of the Emergency Power Off (EPO) Circuit, which overrode the back up electrical
supply, no clear cause of that loss of power was identified. There was no manual activation
of the EPO buttons and a fault within the circuitry was suspected but not established to the
required standard. The loss of electrical power removed the ability to provide x ray images
and consequently prevented commencement of the stenting procedure until power was
regained. Although the stenting was then completed Mrs Dye failed to recover and her
death was confirmed. On balance of probabilities, Mrs Dye would have survived but for the
loss of electrical power.

CORONER’S CONCERNS

During the course of the investigation my inquiries revealed matters giving rise to concern.
In my opinion there is a risk that future deaths could occur unless action is taken. In the
circumstances it is my statutory duty to report to you.

The MATTERS OF CONCERN are as follows:
(brief summary of matters of concern)

The circumstances of Mrs Dye's death are set out above. Her death arose as a consequence
of the combination of an iatrogenic injury sustained during a clinical procedure and an
untimely loss of power to the Catheter Lab where she was being treated for a period of
approximately ten minutes at exactly the time at which her treating consultant required the
benefits of real time xray to facilitate a necessary emergency stenting procedure. The delay
whilst power was restored was a critical factor in this death.
The loss of power arose as a result of the Emergency Power Off (EPO) circuit activating. It
overrode the emergency power back up system. The reason for that activation was unclear
although a physical activation of any of the three EPO buttons was excluded on the
evidence. All staff at the scene were unaware of the cause of the loss of power, never
having experienced such a situation previously, and an engineer was summoned to attend
to reinstate the power, which he did.
There was no light or other indicator within the lab to confirm to those present that the EPO
circuit had activated. Likewise there was no restart button within the lab to permit the EPO
circuit to be reset. That lay within the plant room elsewhere within the hospital.
I received evidence of a small number of accidental activations of EPO circuits nationally
over a 12 month period. It is plainly something which can, and does, occur.
Had staff been aware of the exact cause of the loss of power on this occasion and had they
had the opportunity to reset the circuit without the need to await the arrival of an engineer,
who inturn had to attend a separate plant room, the downtime would likely have been
significantly reduced. Whilst it was not possible to say that the additional time spent on this
occasion made a difference between the patient surviving or not, there may well be future
cases within which such fine margins are time critical.
I received evidence that there is no current guidance in relation to the siting of such
controls remote from the affected room. I invite review of that guidance and of the need for
any consequential training.

ACTION SHOULD BE TAKEN

In my opinion action should be taken to prevent future deaths and I believe you (and/or
your organisation) have the power to take such action.

Dear HM Senior Coroner (Mr Paul D Smith) 

Regulation 28 Report following the inquest into the death of Mrs Dye 

We are sorry to hear about the death of Mrs Dye and we offer our sincere 
condolences to her family. 

Care Quality Commission (CQC) first became aware of the death of Mrs Dye on 
receipt of the Regulation 28 Report to Prevent Future Deaths (the Report) on 25 July 
2025. We understand the death occurred whilst Mrs Dye was receiving surgery at 
Scunthorpe General Hospital, which is a location of Northern Lincolnshire and Goole 
NHS Foundation Trust (the Trust), which is a CQC Registered Provider.  

CQC are named responders in the Report. We are grateful for the extension of time 
granted for our response to be provided, that being until 16 October 2025.  

In the Regulation 28 Preventing Future Deaths report the HM Coroner raised the 
following concerns: 

•  Review of the guidance  
•  Review of the need for any consequential training.  

Having considered the report and additional documentation provided, we understand 
the matters of concern to be as follows: 

•  There is no current guidance in relation to the siting of Emergency Power Off 
(EPO) restart buttons remote from an affected room; review of such guidance 
is invited 

•  Further, review of the need for any consequential training is also invited 

 
 
 
 
 
 It is important to highlight from the outset that CQC does not have the power to set 
guidelines or training expectations, rather we assess a registered provider’s ability to 
meet regulatory requirements. Whilst assessing regulatory compliance can involve 
the application of relevant guidelines, it is not within the scope of CQC’s regulatory 
powers to set the guidelines or any associated training requirements.  

Whilst CQC are unable to provide further response in respect of whether specific 
guidance or training requirements should be implemented, we can set out what 
actions have been taken following receipt of the Report and our engagement with the 
Trust in this matter. 

CQC last undertook a comprehensive inspection of the Trust in June and July 2022.  

The CQC report was published in December 2022, and we rated the Trust as 
“Requires Improvement.” A copy of the report can be found on our website - Trust - 
RJL Northern Lincolnshire and Goole NHS Foundation Trust (02/12/2022) INS2-
12039916291 

Following receipt of the Report, CQC engaged with the Trust and requested 
evidence of any action they had taken to date following the tragic death of Mrs Dye. 
The Trust responded by stating that at the time of the incident, the police had 
assumed primacy over the investigation and had later concluded that there was no 
criminality. The Trust have provided us with a copy of external independent reports 
completed in September 2020 and February 2024 on behalf of the police. The 
reports concluded that the treatment room power interruption was due to an 
unknown electrical fault, with no fault on the part of the Trust, its systems, or staff. 

At the time of the incident the Trust logged it as a serious incident on the Strategic 
Executive Information System (StEIS). However, this was later de-logged with 
agreement from the clinical commissioning group (CCG). This meant the Trust did 
not complete a serious incident investigation report.  

Subsequent external independent inspection reports were recommended by the 
Medicines and Healthcare products Regulatory Agency (MHRA). The reports from 
September 2020 and February 2024 concluded the fault was a rare event caused by 
an electrical fire within the EPO  control room.   

The Trust has confirmed the following recommendations from this report and inquest 
have been actioned:  

•  The EPO’s at Scunthorpe and Grimsby hospitals now have durable labels (x-
ray system emergency power off) and photos were provided as evidence to 
the coroner  

•  The Trust has an Electrical Safety Group which meets on a quarterly basis as 

recommended by the Health Technical Memoranda HTM 06-01 

 
 
 •  The Trust has confirmed the installation reports have been completed in 

accordance with the relevant guidelines  

In relation to the installation of remote on/off buttons with integral lamps the Trust 
discussed this at a governance meeting in April 2025. They also added that there is 
no current guidance requiring this, which was also highlighted by the independent 
engineer.  

CQC will continue to monitor the Trust as part of our regulatory activity.  

We hope that our response addresses your concerns in so far as we are able to. If 
we can provide any further information, then please do not hesitate to contact us.  

Yours sincerely

Dear Coroner, 

Re: Regulation 28 Report to Prevent Future Deaths – Jean Dye who died on 7th 
September 2020.  

Thank you for your Report to Prevent Future Deaths (hereafter “Report”) dated 21st 
July 2025 concerning the death of Jean Dye on 7th September 2020. In advance of 
responding to the specific concerns raised in your Report, I would like to express my 
deep condolences to Jean’s family and loved ones. NHS England is keen to assure 
the family and yourself that the concerns raised about Jean’s care have been listened 
to and reflected upon.   

I am grateful for the further time granted to respond to your Report, and I apologise for 
any  anguish  this  delay  may  have  caused  Jean's  family  or  friends.  I  realise  that 
responses to Coroners’ Reports can form part of the important process of family and 
friends coming to terms with what has happened to their loved ones, and I appreciate 
this will have been an incredibly difficult time for them. 

Your  Report  raised  concerns  that  there  is  no  current  guidance  for  the  siting  of 
Emergency Power Off (EPO) controls, particularly where there are remote from the 
affected room. In this case, the EPO was not sited within the lab nor was there a restart 
button  in  the  lab  to  allow  the  EPO  to  be  reset  -  this  was  in  another  room  located 
elsewhere within the hospital. You invited a review of the guidance and of the need for 
any consequential training.  

Review of the guidance 

There are currently two guidance documents that reference EPO controls. They are 
the  Health  Technical  Memorandum  (HTM)  06-01  Electrical  services  supply  and 
distribution and the Health Building Note (HBN) 01-01: Cardiac facilities.  

HTM 06-01 Electrical services supply and distribution (published in 2007 and updated 
in January 2024) refers to EPOs: 

“Emergency power off switches 

                                                                                                                       
 
 
 
 
 
 
 
 
  
 
 
 
 
 
  
 
 
 15.59  Some  permanently  installed  (fixed)  ME  [medical  electrical]  equipment, 
according  to  the  manufacturer’s  instructions,  require  emergency  power  off 
(EPO)  mushroom  buttons  to  be  provided.  These  switches  are  intended  to 
remove all power in the event of a serious incident such as fire, flood or electric 
shock,  which  is  very  rare.  It  is  important  to  protect  these  switches  from 
accidental  operation,  such  as  an  operator  leaning  on  the  button  or  a  trolley 
pushed against it. 

15.60 Protection against accidental operation of the EPO can be achieved by 
careful positioning of the button and using one fitted with a shroud (often a semi-
circular  protrusion  over  the  top).  Care  should  be  taken  to  avoid  making  the 
button too difficult to operate; therefore, covers that need to be lifted should be 
avoided. 

15.61  The  EPO  button(s)  may  require  a  double-pole  contact  to  enable  two 
circuits  to  be  formed.  One  will  remove  the  power  to  the  equipment  supply 
contactor  and  the  other  circuit  may  be  needed  to  shut  down  any  UPS 
[uninterruptible power supply] the system is using in order to fully isolate the 
source of power. 

15.62  EPO  buttons  should  also  be  clearly  marked  (labelled)  to  indicate  their 
function  and  the  related  equipment.  For  example,  “X-ray  system  Emergency 
Power Off”.” 

This guidance is focused on stopping accidental activation of the EPO, but does not 
currently state what to do if the EPO is activated in error. The NHS England Estate’s 
team advise that they will address this when the HTM 06-01 guidance document is 
next updated. 

NHS  England’s  Head  of  Hard  Facilities  Management  has  been  contacted  by  an 
independent  advisor  to  the  Medicines  and  Healthcare  products  Regulatory  Agency 
(MHRA)  on  electrical  safety,  who  was  involved  in  the  inquest  hearing.  The  MHRA 
advisor raised that: 

•  The  EPO  control  itself  does  not  need  to  be  in  the  same  room  as  the 

equipment/users, just a means to reset it; 

•  A risk assessment on power failure needs to be conducted as part of the room 

design; 

•  He has suggested the following wording be used in the HTM 06-01 guidance 

when it is rewritten: 

“All EPOs and associated contacts in the EPO circuit should as a minimum, be 
replaced when an interventional x-ray room is replaced and would suggest this 
is common practice with all medical radiological equipment.    

All  interventional  x-ray  rooms  shall  be  inspected  and  if  the  contactor  is  in 
another location, (operator cannot see the on/off buttons from the x-ray room), 
a remote on/off is fitted. The remote on/off buttons shall have integral lamps.” 

  
  
  
  
 
  
  
  
 Guidance on cardiac catheter labs, the setting for this incident, are covered in HBN 
01-01  “Cardiac  facilities”.  The  current  version  of  HBN  01-01  was published  in 2013 
(updated in January 2024) and includes the following references to power: 

“Catheter laboratories 

5.9 Key engineering considerations include: 

… It is recommended that removal of a catheter under X-ray control is possible 
in the event of mains power failure; this requirement should be discussed with 
the hospital’s and system manufacturer’s engineers.” 

Earlier guidance, published in 2001 by the former NHS Estates (an Executive Agency 
of DHSC abolished in 2005) called HBN 06-01 “Facilities for diagnostic imaging and 
interventional  radiology”  is  in  the  process  of  being  updated,  but  excludes  cardiac 
facilities  covered  separately  in  HBN  01-01.  The  draft  updated  HBN  06-01  currently 
includes the following text on EPO buttons: 

6.62  As  set  out  in  HTM  06-01,  emergency  stop  buttons  should  be  provided 
within imaging examination rooms. There are three main types of emergency 
button (see AXREM emergency stop button label recommendations): 
•  emergency  power-off  –  cuts  mains  power  and  mains  power  UPS  to  the 

• 

whole room 
imaging system emergency power-off (also medical equipment emergency 
power-off) – cuts power on a local control circuit specific to particular item(s) 
of medical equipment. For example, the X-ray system emergency power-off 
button would cut power to the X-ray machine and its local equipment UPS 
to ensure X-rays cannot be generated in an emergency situation. The mains 
power to the room would remain on so that items on separate circuits such 
as lights and IT would stay on 

•  emergency motion stop – stops movement on the imaging equipment in the 

event of an emergency, to prevent harm to patients. 

6.63  Emergency-stop switches should be clearly labelled, easily accessible 
by staff and mounted at a height which reduces the risk of accidental use. They 
should be installed in both the examination and control area, with advice sought 
from  the  RPA  [radiation  protection  advisor]  or  MRSE  [magnetic  resonance 
safety expert] (as appropriate) on button locations. 

As a result of the discussions between the Head of Hard Facilities Management and 
the  MHRA  advisor,  amendments  are  to  be made  to  this  text.  The  amendments  will 
also address the location of reset buttons in the update.  

An update to HTM 06-01 is planned and the content relating to EPOs will be reviewed 
in  light  of  this  incident  and  the  final  published  content  for  HBN  06-01,  to  ensure 
alignment of guidance. The update is due to be completed in the financial year 2026-
27. 

 
  
  
 
  
  
  
 
  
 
 Training 

Competency and training for engineers will be included in the HTM update described 
above. 

I  would  also  like  to  provide  further  assurances  on  the  national  NHS  England  work 
taking  place around  the  Reports  to  Prevent Future  Deaths.  All  reports  received  are 
discussed  by  the  Regulation  28  Working  Group,  comprising  Regional  Medical 
Directors,  and  other  clinical  and  quality  colleagues  from  across  the  regions.  This 
ensures that key learnings and insights around events, such as the sad death of Jean, 
are shared across the NHS at both a national and regional level and helps us to pay 
close attention to any emerging trends that may require further review and action.   

Thank you for bringing these important patient safety issues to my attention and please 
do not hesitate to contact me should you need any further information.  

Yours sincerely,  

National Medical Director 
NHS England
