1. Background
Data quality
Incident records in the Incident Recording System (IRS) are the responsibility of and quality assured by Fire and Rescue 天美影院 (FRSs). The Department and FRSs work together to improve the data within the IRS and minimise any inconsistencies or errors. However, as the IRS was not designed with record level datasets in mind, a very small number of previously unidentified inconsistencies have been discovered (see project overview for further detail).
IRS incident records are a judgement call of the lead fire officer at the time of the incident. The quality of the information provided by fire and rescue services is variable and its accuracy cannot be guaranteed, especially at a record level, for instance some records involve estimation by those in attendance.
Suffolk FRS could not submit all incidents before the datacut date, due to technical reasons. Therefore, these statistics do not contain data for all incidents attended from September 2024 to March 2025 from Suffolk. The data will be revised in due course, as incidents are updated to the IRS.
Dataset rationale
Casualties in fires were mentioned in a user survey carried out to gather views on the most useful datasets to publish. There is also a clear public good in being able to analyse details on the causes of casualties. The Department has, and will continue to, engage with stakeholders, such as statistical users and FRSs, to gauge opinion on other datasets to publish.
Dataset definition
Non-fatal casualties in fires are those that fit into one of four sub-categories:
Hospital severe - at least an overnight stay in hospital as an in-patient.
Hospital slight - attending hospital as an outpatient (not a precautionary check).
First aid given - first aid given at scene (by anyone), including after a precautionary check.
Precautionary check - a precautionary check (to attend hospital or to see a doctor) was recommended (by anyone).
Information on non-fatal casualties in non-fire incidents are not included in this dataset.
These records, when aggregated, also match the published statistics as these statistics are for non-fatal casualties in fires.
The data in this dataset are consistent with records that reached the IRS by 1 May 2025. The Department only has jurisdiction for fire policy in England, and therefore has published the non-fatal casualties in fires data for England only.
2. Variable by variable - scene setting
Variable Name: FINANCIAL_YEAR Variable Description: The financial year the fire took place IRS Question: 2.1 (based on)
A financial year runs from 1 April to 31 March. Record level information is published from financial year 2010 to 2011 - although the IRS began in April 2009 there are a few minor issues with the financial year 2009 to 2010 records which mean that while statistics at higher levels are robust some of the incident level records are not of a sufficient quality to publish. Incidents are allocated to financial year depending on the time of the call, which is usually collected through automatic systems, so for example an incident where the call was made at 23.59 on March 31st 2010 but the incident was closed at 01.34 on April 1st 2010 would be allocated to financial year 2009 to 2010 not financial year 2010 to 2011.
Variable Name: HOUR_BAND Variable Description: The hour of the day the fire took place IRS Question: 2.1 (based on)
Incidents are allocated to the hour band of the day (00-01, 01-02 etc) depending on the time of the call, which is usually collected through automatic systems, so for example an incident where the call was made at 23.59 but the incident was closed at 01.34 on April 1st 2010 would be allocated to 鈥23-00鈥 not 鈥00-01鈥.
3. Variable by variable - situation
Variable Name: INCIDENT_LOCATION_TYPE Variable Description: The type of location the incident occurred in IRS Question: 3.2
Incidents are categorised into one of the four following locations - 鈥渄welling鈥, 鈥渙ther building鈥, 鈥渞oad vehicle鈥 or 鈥渙ther outdoors鈥.
A dwelling is defined as 鈥渁 property that is a place of residence i.e. occupied by households鈥. The definition includes residential homes, sheltered accommodation, caravans, houseboats and Houses of Multiple Occupancy (HMO). However, it does not include hostels, hotels and residential institutions, bed and breakfast establishments, nursing/care homes and student halls of residence, which are defined as within 鈥渙ther buildings鈥. Fires in common areas of flats (such as stairs) are defined as within 鈥渄wellings鈥.
Variable Name: ALARM_SYSTEM Variable Description: Whether a smoke alarm was present and if it operated. IRS Question: Combination of 5.8 and 5.11
In a case where more than one alarm system was present the 鈥渂est鈥 case is chosen, i.e. 鈥淎larm present and raised the alarm鈥 is the best case, 鈥淎larm present but did not raise alarm鈥 is the second best case, 鈥淎larm present but did not operate鈥 is the third best case and 鈥淎larm absent鈥 is the worst case. This is not applicable to some vehicle and outdoor fires as the question is only asked of primary building fires, so these are marked as 鈥淎larm absent鈥.
Variable Name: OCCUPANCY_STATUS Variable Description: The household occupancy type at the time of the incident IRS Question: 8.15
The options for this variable are 鈥3 or more adults under pensionable age, no child/ren鈥, 鈥3 or more adults with dependant child/ren鈥, 鈥淐ouple both under pensionable age with no children鈥, 鈥淐ouple one or more over pensionable age, no child/ren鈥, 鈥淐ouple with dependant child/ren鈥, 鈥淟one parent with dependant child/ren鈥, 鈥淟one person over pensionable age鈥, 鈥淟one person under pensionable age鈥, 鈥淣ot known鈥, 鈥淥ther鈥.
4. Variable by variable - the fire
Variable Name: ACCIDENTAL_OR_DELIBERATE Variable Description: Whether the incident was recorded as an accidental or deliberate fire IRS Question: 5.15
A deliberate fire is a fire believed to have been started deliberately such as suspected arson and some fires started by children, psychiatric patients, suicides and attempted suicides. Accidental fires include those where the motive was recorded as 鈥渘ot known鈥. Whilst we would not expect the fires for 鈥渄eliberate fires鈥 to match precisely the in the tables from the Crime in England and Wales statistical release, we would expect 鈥渄eliberate fires for dwellings, other buildings and vehicles to be similar to the arson figures.
Variable Name: CAUSE_OF_FIRE Variable Description: The main cause of the fire IRS Question: 8.1
This variable contains options that best describe the main cause of the fire. FRSs are not necessarily certain that the fire was due to the cause given, only that the cause was one that could be reasonably supposed, given the evidence available. The cause may change as more evidence through a fire investigation becomes available.
Variable Name: SOURCE_OF_IGNITION Variable Description: The source of ignition for the fire IRS Question: 8.4
This variable contains options that best describe the source of ignition for the fire. FRSs are not necessarily certain what the source of ignition for the fire is, only that the source of ignition was one that could be reasonably supposed, given the evidence available. The source of ignition may change as more evidence through a fire investigation becomes available.
Variable Name: FIRE_START_LOCATION Variable Description: The type of room/compartment the fire started in IRS Question: 8.14
This variable contains options that best describe the room or compartment where the fire started.
5. Variable by variable - victim details
Variable Name: VICTIM_LOCATION_START Variable Description: Where the victim was when the fire started IRS Question: 9.10
The options for this variable are 鈥淩oom, cabin or compartment of fire origin鈥, 鈥淒ifferent floor, room, cabin or compartment than of fire origin鈥 and 鈥淥ther, unknown or not applicable鈥.
Variable Name: VICTIM_LOCATION_FOUND Variable Description: Where the victim was when they were found IRS Question: 9.11
The options for this variable are 鈥淩oom, cabin or compartment of fire origin鈥, 鈥淒ifferent floor, room, cabin or compartment than of fire origin鈥 and 鈥淥ther, unknown or not applicable鈥.
Variable Name: VICTIM_AGE Variable Description: The age of the victim IRS Question: 9.7
The age of the victim is sometimes unknown and sometimes estimated. To reduce personal data risk, ages are grouped into bands. The options for this variable are 鈥淯nder 1鈥, 鈥1 to 5鈥, 鈥6 to 10鈥, 鈥11 to 16鈥, 鈥17 to 24鈥, 鈥25 to 39鈥, 鈥40 to 54鈥, 鈥55 to 64鈥, 鈥65 to 79鈥, 鈥80 or over鈥 and 鈥淯nspecified鈥.
Variable Name: VICTIM_GENDER Variable Description: The gender of the victim IRS Question: 9.8
The gender of the victim is sometimes unknown. The options for this variable are 鈥淔emale鈥, 鈥淢ale鈥 and 鈥淣ot known鈥.
6. Variable by variable - outcomes
Variable Name: VICTIM_RESCUED Variable Description: Whether the victim was rescued IRS Question: 9.13
A rescue is where a person has received physical assistance to get clear of the area involved in the incident. A baby carried out in the course of another person鈥檚 escape is not included as a rescue, however if a rescuer (including FRS personnel) entered the building or other area affected by the fire in order to rescue the baby, then the baby is recorded as a rescue.
Where 鈥渄on鈥檛 know鈥 is recorded this is included as 鈥渘o鈥 in this variable.
Variable Name: INJURY_TYPE Variable Description: The nature of the injury IRS Question: 9.22
This variable shows the option that best corresponds to the victim鈥檚 injury type.
Variable Name: INJURY_SEVERITY Variable Description: The severity of the injury IRS Question: 9.24
The options for this variable are-
鈥淗ospital Severe鈥 -Where at least an overnight stay in hospital as an in-patient is required.
鈥淗ospital Slight鈥 - Where attending hospital as an outpatient (not a precautionary check) is required.
鈥淔irst aid鈥 - Where first aid was given at scene (by anyone), including after a precautionary check.
鈥淧recautionary check鈥 - Where a precautionary check (to attend hospital or to see a doctor) was recommended (by anyone).
Variable Name: FIRE_RELATED Variable Description: Whether the victim鈥檚 injuries were related to the fire IRS Question: 9.21
Fire-related casualties are those that would not have otherwise occurred had there not been a fire. Those where the role of fire in the casualty was 鈥渘ot known鈥 are included in 鈥渇ire-related鈥.
Variable Name: CASUALTY_TOTAL Variable Description: Whether the incident involved more than one casualty IRS Question: 9.6
The options for this variable are 鈥淪ingle casualty incident鈥 and 鈥淢ultiple casualty incident鈥. This includes other victims who are fire-related fatalities but not fatalities unrelated to the fire.
