RIDDOR Regulations 2013, Reporting of Incidents Diseases and Dangerous Occurrences Regulations 2013

In force 01/10/2013



The RIDDOR Regulations 2013 (Reporting of Incidents, Diseases and Dangerous Occurrences Regulations 2013) revoke and replace, with amendments, the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (S.I. 1995/3163) (“the 1995 Regulations”) and the

Reporting of Injuries, Diseases and Dangerous Occurrences (Amendment) Regulations 2012 (S.I. 2012/199) (“the 2012 Regulations”).


They maintain requirements that the responsible person must notify, and subsequently send a report to, the relevant enforcing authority by an approved means in relation to fatal and certain non-fatal work-related accidents, specified diseases contracted by persons at work and certain specified dangerous occurrences.


RIDDOR is the law that requires employers, and anyone else with responsibility for health and safety within a workplace, to report and keep records of:

  • work-related deaths
  • serious injuries
  • cases of diagnosed industrial disease
  • certain ‘dangerous occurrences (near miss accidents)


The main changes simplify the reporting requirements in the following areas:

  • The classification of ‘major injuries’ to workers is being replaced with a shorter list of ‘specified injuries’
  • The existing schedule detailing 47 types of industrial disease is being replaced with eight categories of reportable work-related illness
  • Fewer types of ‘dangerous occurrence’ will require reporting


There are no significant changes to the reporting requirements for:

  • Fatal accidents
  • Accidents to non-workers (members of the public)
  • Accidents which result in the incapacitation of a worker for more than seven days


Recording requirements will remain broadly unchanged, including the requirement to record accidents resulting in the incapacitation of a worker for more than three days.


The 2012 version of INDG453 -guidance on the RIDDOR Regulations applies up to and including 30 September 2013.


From 1 October 2013, the guidance in the 2013 revision of INDG453 applied. The leaflet identifies what is required from employers and provides updated information about RIDDOR. Please note that if you downloaded a draft copy before 1 October, the draft is superseded by the version published on 01 October.



Types of reportable injury



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


Specified injuries to workers

The list of ‘specified injuries’ in RIDDOR 2013 replaces the previous list of ‘major injuries’ in RIDDOR 1995.

Specified injuries include (regulation 4):

  • 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);
  • scalpings (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, which leads to hypothermia, heat-induced illness or requires resuscitation or admittance to hospital for more than 24 hours.


Over-seven-day injuries 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).


Injuries to non-workers

Work-related accidents involving members of the public or people who are not at work must be reported if a person is injured, and is taken from the scene of the accident to hospital for treatment to that injury. There is no requirement to establish what hospital treatment was actually provided, and no need to report incidents where people are taken to hospital purely as a precaution when no injury is apparent. If the accident occurred at a hospital, the report only needs to be made if the injury is a ‘specified injury’ (see above).


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 (regulations 8 and 9):

  • 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.


Reportable dangerous occurrences

Dangerous occurrences are certain, 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 coming into contact with overhead power lines;
  • the accidental release of any substance which could cause injury to any person.


Certain additional categories of dangerous occurrences apply to mines, quarries, offshore workplaces and certain transport systems (railways etc). For a full, detailed list, refer to the online guidance at: www.hse.gov.uk/riddor.


Reportable gas incidents

A distributor, filler, importer or supplier of flammable gas and who learns, either directly or indirectly,  of the following events arising in connection with the gas they distributed, filled, imported or supplied, they must report the event

  • that someone has died,
  • lost consciousness,
  • been taken to hospital for treatment to an injury


A gas engineer registered with the Gas Safe Register must provide details of any gas appliances or fittings that are consider to be dangerous to the extent that people

  • could die,
  • lose consciousness or
  • require hospital treatment

This may be due to the design, construction, installation, modification or servicing, and could result in:

  • an accidental leakage of gas;
  • inadequate combustion of gas;
  • inadequate removal of products of the combustion of gas.

An Employer must keep a record of:

  • any accident, occupational disease or dangerous occurrence which requires reporting under RIDDOR; and
  • any other occupational accident causing injuries that result in a worker being away from work or incapacitated for more than three consecutive days (not counting the day of the accident but including any weekends or other rest days). You do not have to report over-three-day injuries, unless the incapacitation period goes on to exceed seven days.
