INVESTIGATION and INQUEST 

Chester Alan Stanley MOSSOP died on 3 June 2022 following an incident at his home 
address on 29 May 2022. Baby Chester’s death was reported to HM Coroner for Cumbria 
on 6 June 2022 and his death formally transferred from HM Coroner Newcastle. An 
investigation into his death (in accordance with Section 1 Coroners and Justice Act) was 
commenced on the same day.  

An inquest into Chester’s death was opened on 23 February 2023 and his inquest was 
heard before me on 13 April 2023.  

The medical cause of Chester’s death was: 

1a Hypoxic ischaemic brain injury 
1b Cardiac arrest (resuscitated) 
1c Drowning 

The determination was: 

Chester Alan Stanley Mossop was a healthy and well-looked after 9 months' old baby. On 
29 May 2022, Chester was placed in a bath seat in a bath of warm water at his home. 
After approximately 20 minutes of bath time, Chester was left alone in his bath seat. After 
a few minutes, Chester was found face down in the bath, the bath seat having become 
unfixed. Chester was given immediate CPR which was continued by attending police, 
paramedics and clinicians. Chester was conveyed to the Great North Children's' Hospital 
at the Royal Victoria Infirmary by air ambulance. Everything was done to try to save 
Chester's life. However, an MRI scan showed that Chester had sustained an unsurvivable 

 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 brain injury due to drowning and he died in his mother's arms on 3 June 2022 at 18:05 at 
the Royal Victoria Infirmary. 

The conclusion of the inquest was: 

Accidental Death 

I rejected, giving full reasons, a submission that Chester’s death was due to neglect and I 
made no finding in that respect.  

I rejected, giving full reasons, a submission that Chester’s death was due to unlawful 
killing (by gross negligence manslaughter).

CIRCUMSTANCES OF THE DEATH 

Chester was a healthy and well looked after 9 months’ old baby. He was usually fit and 
well. However, on 29 May 2022, he had a mild viral infection (which was confirmed at 
post-mortem).  

Chester was placed in a bath seat and given a bath in suitably warm water. The water 
level was higher than advised - so that Chester did not get chilled.  

After about 20 minutes of bath time, Chester was left alone in his bath seat whilst a plug-
in diffuser (to help his cold) was prepared in his bedroom. It was believed that the bath 
seat was safe and secure to hold him in place.  

After a few minutes, Chester was found face down in the bath. The bath seat had become 
unfixed. There were no sounds that Chester was in distress or difficulty. He was 
immediately removed from the bath and given immediate CPR by a trained adult. 
Emergency services were quickly on scene and CPR was continued by police, paramedics 
and clinicians. Return of spontaneous circulation was achieved. 

Chester was flown by air ambulance to the Great North Children’s Hospital at the Royal 
Victoria Infirmary in Newcastle. However, an MRI scan undertaken on 2 June 2022 
showed that Chester had an extensive severe brain injury consistent with severe global 
hypoxic ischaemia caused by drowning. It was considered that Chester was unlikely to 
survive and further intensive care treatment was not in his best interest.  

Intensive care support was withdrawn on 3 June 2022 and Chester died peacefully in his 
mother’s arms at 18:05.  

I received a statement from RoSPA (the Royal Society for the Prevention of Accidents) 
setting out that: 

•  Baby bath seats are unstable and prone to toppling over leaving the baby 

trapped in the water. 

•  Bath seats may give parents and carers a false sense of security that baby is safer 

in a bath seat and can be left alone (despite warnings that this should not 
happen). 
There can be a misconception that a baby bath seat is a safety product – this is 
not the case.  

• 

•  Under no circumstances should parents regard bath seats as a safety aid and 

leave a child out of arms reach.  

•  RoSPA is aware of incidents where parents have been in the room, but away 

from the baby, with tragic results.  

•  RoSPA is aware of a number of drownings of young children in the bath where a 

• 

baby bath seat has been used.  
There may be some bath seats that are less stable than others or that have 
inadequate methods to hold them in place.  

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 I heard no evidence about any safety concerns with the bath seat in question.  

The Child Death Overview Panel (“CDOP”) advised me that a Bath Safety Alert had been 
issued in the North-East and North Cumbria. This can be viewed at: 

www.nenc-healthiertogether.nhs.uk/parentscarers/keeping-your-child-safe/bath-safety-
advice 

I requested an update on several matters but these were not available at the date of 
Chester’s inquest. Given the “ancillary nature” of Reports to Prevent Future Deaths and to 
avoid the distress of an adjournment to Chester’s family, I decided to proceed with the 
inquest.

CORONER’S CONCERNS 

The evidence revealed matters giving rise to concern. In my opinion there is a risk that 
future deaths will occur unless action is taken. In the circumstances it is my statutory duty 
to report to you. 

The MATTERS OF CONCERN are as follows: 

I am aware of similar tragic deaths to Chester’s and inquests held by my fellow Coroners. 
RoSPA is also aware of fatal and non-fatal incidents.  

The use of bath seats is of concern to RoSPA.  

Whilst I am aware of the regional Bath Safety Advice (set out above), I am not aware that 
similar advice has been distributed on a national level to healthcare professionals and to 
parents / carers.  I am not aware whether parents / carers are provided with advice about 
the safe use of bath seats as part of e.g. health visits.  

I am concerned that bath seats may given parents a false sense of security that their child 
is safe. Bath seats are not safety devices.  

6 

ACTION SHOULD BE TAKEN 

In my opinion action should be taken to prevent future deaths and I believe the  

NATIONAL HEALTH SERVICE 
OFFICE OF PRODUCT SAFETY AND STANDARDS 

has the power to take such action.

Re:  Regulation  28  Report  to  Prevent  Future  Deaths  –  Chester  Alan  Stanley 
Mossop who died on 3 June 2022.  

Thank you for your Report to Prevent Future Deaths (hereafter “Report”) dated 20 April 
2023 concerning the death of Chester Alan Stanley Mossop who died on 3 June 2022. 
In advance of responding to the specific concerns raised in your Report, I would like 
to express my deep condolences to Chester’s family and loved ones. NHS England 
are  keen  to  assure  the  family  and  the  coroner  that  the  concerns  raised  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 Chester’s family. I realise that responses to 
Coroner Reports can form part of the important process of family coming to terms with 
what has happened to their loved ones and appreciate this will have been an incredibly 
difficult time for them. 

Your  Report  raised  that  the  use  of  bath  seats  for  babies  is  a  concern  to  the  Royal 
Society for the Prevention of Accidents (RoSPA) and that their use can give parents a 
false sense of security. You raised the concern that you were not aware if the advice 
from RoSPA had been distributed on a national level to healthcare professionals and 
to  parents/carers,  and  whether  parents/carers  were  provided  with  advice  about  the 
safe use of bath seats.  

We were very saddened to hear about this case which has been carefully considered 
by  colleagues  across  the  organisation  including  from  Patient  Safety,  Maternity  and 
Children and Young People teams. In response to the concerns raised, NHS England 
will be updating its ‘Washing and bathing your baby’ website page to include guidance 
on the use of bath seats for babies. This will make clear that bath seats for babies are 
not  recommended  for  use  by  RoSPA  or  by  the  Child  Accident  Prevention  Trust 
(CAPT),  who  we  have  engaged  with  on  this  matter,  and  that  they  are  not  safety 
devices.  The  update  to  the  website  will  also  include  text  to  raise  awareness  with 
parents/carers that babies can drown within seconds, in just a few centimetres of water 
and with no noise or struggle and reemphasise that babies of any age should always 
be kept at arm’s reach of an adult whenever they are in the bath. These updates to 
the  website  are  moving  through  NHS  England’s  internal  approval  process  and  are 

                                                                                                                       
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 expected  to  be  made  imminently.  We  are  happy  to  advise  you  as  soon  as  these 
updates have been made.  

This advice will also be incorporated into staff bulletins for midwifery and healthcare 
workers, reminding staff to communicate this important safety message to parents and 
carers  during  their  interactions.  I  am  also  aware  that  my  Maternity  colleagues  are 
picking up on the concerns raised with the Royal College of Midwives (RCM) and the 
British  Association  of  Perinatal  Medicine  (BAPM),  to  consider  whether  any  further 
awareness work can be implemented via their networks.  

NHS England will also be sharing the case through Patient Safety bulletins and will 
discuss  at  our  next  national  Regulation  28  Working  Group  meeting  in  August.  
Regional  colleagues  who  sit  on  the  Working  Group  membership  will  be  asked  to 
ensure that the safety message around bath seats is shared to their systems, to help 
raise further awareness.  

We have discussed this case and the concerns raised with colleagues at the Office for 
Health Improvement and Disparities (OHID) at the Department of Health and Social 
Care and are advised that they will be raising the case with their networks as a safety 
alert.  

The  National  Child  Mortality  Database  (NCMD)  will  also  shortly  be  publishing  a 
thematic  report  on  deaths  of  children  and  young  people  due  to  traumatic  incidents 
between  April  2019  and  April  2023,  which  will  include  drownings.  Many  of  the 
drownings considered within the scope of the report did take place when a child or 
baby had been left unsupervised. As advised above, NHS England are undertaking a 
communications push to highlight the importance of never leaving babies of any age 
unsupervised  while  in  the  bath.  We  will  also  of  course  consider  any  additional 
recommendations made by the NCMD within its report.  

NHS England has been sighted on the response to your Report from the Office for 
Product Safety and Standards (OPSS) and I am pleased to hear that the OPSS will 
also be assessing the safety and compliance with legal requirements of similar models 
of baby bath seats to the one used by Chester, and that they will take any relevant 
action.  

I would also like to provide further assurances on national NHSE 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 preventable deaths are shared across the NHS at both a national 
and regional level and helps us 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,

Miss Kirsty Gomersal 
HM Area Coroner 
County of Cumbria

Cockermouth, CA13 9PT 

Dear Miss Kirsty Gomersal, 

Thank you for your Regulation 28 Report (Prevention of Future Deaths) dated 20 April 
2023, following your investigation and inquest into the death of Chester Allan Stanley 
Mossop.  

First, I would like to say how deeply saddened I was on hearing of the tragic death of 
baby Chester. I would be grateful if you could pass on my condolences to the family if 
you have the opportunity to do so. 

The  Office  for  Product  Safety  and  Standards  (OPSS)  is  the  UK’s  national  product 
regulator.  The  UK  has  a  product  safety  system  designed  to  provide  a  high  level  of 
protection for consumers and all consumer products including baby bath seats, must 
be safe before they can be sold on the UK market. The safety of baby products is a 
priority  area  for  OPSS  and  we  have  recently  taken  action  to  prevent  the  sale  of  a 
number of unsafe baby products including baby self-feeding devices. 

Baby  bath  seats  are  regulated  under  the  General  Product  Safety  Regulation  2005 
(GPSR).  This  places  an  obligation  on  manufacturers  or  importers  to  ensure  their 
products are safe before they can be placed on the market (Regulation 5 of GPSR). 
They must also provide safety information to enable consumers to  assess risks that 
are  not  immediately  obvious  without  adequate  warnings  and  to  take  precautions 
against those risks (Regulation 7 of GPSR). Distributors have a separate duty to act 
with due care to ensure that products they offer for sale comply with the law; are safe; 
and to pass on the necessary information on the risks posed by the product (Regulation 
8 of GPSR).   

The Office for Product Safety and Standards is part of the Department for Business and Trade. We strive to enhance 
protections for consumers and the environment and drive increased productivity, growth and business confidence.

 Since  receiving  your  Report,  OPSS  has  been  in  contact  with  your  office  to  obtain 
further  details  of  the  product  involved  in  this  incident.  As  a  result,  OPSS  will  be 
assessing the safety and compliance for similar models of baby bath seat to assess 
their compliance with legal requirements. While we do not currently have any evidence 
that the product itself is unsafe or non-compliant, should that be identified, we have a 
range of actions open to us to ensure products are brought into compliance or removed 
from the market.  

We  will  also  work  with  the  Baby  Products  Association  (BPA),  the  relevant  trade 
association for the sector, to ask them to remind their members of the requirements for 
including appropriate instructions for safe use and to ensure that any safety warnings 
for baby bath seats are suitably clear and prominent. We have worked closely with the 
National  Health  Service  (NHS)  on  our  programme  of  activity  on  the  safety  of  baby 
products and will ask them to consider whether there is an opportunity to include safety 
messages  related  to baby  bath  seats  through  their  communications  with  healthcare 
professionals and new parents.   

Thank you again for bringing this tragic case to our attention. 

Yours Sincerely,  

Deputy Chief Executive  
Office for Product Safety and Standards 

The Office for Product Safety and Standards is part of the Department for Business and Trade. We strive to enhance 
protections for consumers and the environment and drive increased productivity, growth and business confidence.
