The importance of RIDDOR and how to report

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013, commonly known as RIDDOR is the set of regulations that puts a duty on employers, the self-employed and people in control of work premises (the Responsible Person) to report certain serious incidents and keep records of:

  • Deaths and injuries caused by workplace accidents.

  • Specified injuries to workers.

  • Diagnosed cases of occupational disease, carcinogens mutagens and biological agents.

  • Certain dangerous occurrences (near misses)/gas incidents.

All incidents in the workplace, depending on their nature and consequence, should be recorded, and investigated either informally or formally to determine the cause and put corrective actions in place to be taken to prevent a recurrence. Formal recording and investigation are required for those injuries that account for over-three-day incapacitation but less than seven, even though they are not RIDDOR reportable. As the responsible person, you must keep an accident book under the Social Security (Claims and Payments) Regulations 1979, to record workplace accidents.

Formal investigation is normally carried out through a detailed accident investigation procedure by an incident co-ordinator and/or line manager, who completes an ‘Incident Report and Investigation’. However, if the incident is RIDDOR reportable, a formalised reporting procedure has to be followed.

It is important to bear in mind, that as a line manager or incident co-ordinator, would be acting as a notifier, therefore acting as the responsible person under RIDDOR legislation and under a legal obligation to make the notification and have a lawful basis for processing the personal data of the injured person (data subject).

Responsible persons and/or the notifier should complete the appropriate online RIDDOR report form, depending on the nature of the incident there are various reporting forms to choose from. These forms are listed on the Health and Safety Executive (HSE) website. The form is then submitted directly to the RIDDOR database. After submitting the RIDDOR report form, there will be an option to download a copy for your records.

Although all incidents can be reported online, there is a telephone service provided for reporting fatal/specified incidents only. In this instance, the responsible person can call the Incident Contact Centre on 0345 300 9923 (opening hours Monday to Friday 8.30am to 5pm).

However, it is helpful to clarify further, what some serious incidents would need reporting.

Deaths and injuries caused by workplace accidents


Deaths. All deaths because of a work-related accident to workers and non-workers, except for suicides, must be reported if they arise from a work-related accident, including an act of physical violence to a worker.

Over-seven-day incapacitation to workers. This is where an employee, or self-employed person, is away from work or unable to perform their normal work duties for more than seven consecutive days (not counting the day of the accident but does include weekends and rest days). The report must be made within 15 days of the accident.

Injuries to non-workers. You must report injuries to members of the public or people who are not at work if they are injured through a work-related accident and are taken from the scene of the accident to hospital for treatment to that injury. There is no need to report incidents where people are taken to hospital purely as a precaution when no injury is apparent.

Specified injuries to workers


Specified injuries to be reported include:

  • a fracture, other than to fingers, thumbs, and toes.

  • amputation of an arm, hand, finger, thumb, leg, foot, or toe.

  • permanent loss of sight or reduction of sight.

  • crush injuries leading to internal organ damage.

  • serious burns (covering more than 10% of the body or damaging the eyes.

  • respiratory system or other vital organs).

  • scalping's (separation of skin from the head) which require hospital treatment.

  • unconsciousness caused by head injury or asphyxia.

  • any other injury arising from working in an enclosed space, or which leads to hypothermia, heat-induced illness or requires resuscitation or admittance to hospital for more than 24 hours.

Here you will find further guidance on specified injuries.

Reportable occupational diseases


Employers and self-employed people must report diagnoses of certain occupational diseases, where these are likely to have been caused or made worse by their work.

These diseases include:

  • carpal tunnel syndrome.

  • severe cramp of the hand or forearm.

  • occupational dermatitis.

  • hand-arm vibration syndrome.

  • occupational asthma.

  • tendonitis or tenosynovitis of the hand or forearm.

  • any occupational cancer.

  • any disease attributed to an occupational exposure to a biological agent.

Further guidance on occupational diseases, occupational cancers and diseases associated with biological agents is available.

Certain dangerous occurrences (near misses)/gas incidents


Dangerous occurrences. These are specified near-miss events. Not all such events require reporting. There are 27 categories of dangerous occurrences that are relevant to most workplaces, for example:

  • the collapse, overturning or failure of load-bearing parts of lifts and lifting equipment.

  • plant or equipment meeting overhead power lines.

  • the accidental release of any substance which could cause injury to any person.

Further guidance on dangerous occurrences is available. In addition, specific categories are available of dangerous occurrences applicable to mines, quarries, offshore workplaces and relevant transport systems (railways etc). 

Gas incidents. Distributors, fillers, importers & suppliers of flammable gas must report incidents where someone has died, lost consciousness, or been taken to hospital for treatment to an injury arising in connection with that gas. Such incidents should be reported using the Report of a Flammable Gas Incident - online form.
