RIDDOR regulations explained

RIDDOR stands for Reporting of Injuries, Diseases, and Dangerous Occurrences Regulations. It was introduced in 1995 to try and add a more structured approach to how employers report any health and safety-related issues in the workplace. The regulations are broken down into three key areas; the reporting of injuries, diseases, and other ‘dangerous occurrences’ that are related to work.

Not every work-related incident needs to be reported. This is only necessary if they meet the following RIDDOR guidelines.

Reportable incidents

The death of any person

All incidents resulting in the death of a worker or non-worker will require the filing of a RIDDOR report if they arise from a work-related incident. The exception is in situations concerning suicide.


Specified injury to workers

The Specified Injuries include:

  • Bone fractures diagnosed by a registered medical professional
  • Crushing of the head or body that results in internal or brain damage
  • Burns covering more than 10% of the body or cause damage to the respiratory system, eyes and vital organs
  • Scalping
  • Head injuries or asphyxia that cause loss of consciousness
  • Injuries that occurred in an enclosed workplace resulting in: heat-induced illness, hypothermia, resuscitation or hospitalisation for more than 24 hours

Any of the listed injuries should be reported following the RIDDOR guidelines.


Seven-day injury

If the individual is off for more than seven consecutive days, then it must be reported. This doesn’t include the day of injury and must be reported within 15 days of the injury’s occurrence.


Three-day injury

If a worker is off for more than three days as a result of an injury the incident must be recorded but does not need to be reported.


Non-Fatal Accidents to Members of the Public

Any injury to a non-worker that results in hospitalisation must be reported in compliance with the RIDDOR guidelines.


Occupational Diseases

Both employers and self-employed individuals must report any diagnosis of the following conditions in a RIDDOR report:

  • Carpal Tunnel Syndrome
  • Cramp of the hand or forearm
  • Occupational dermatitis
  • Hand Arm Vibration Syndrome:
  • Occupational asthma:
  • Tendonitis or tenosynovitis:

A doctor must provide a diagnosis in writing for an employer however a verbal statement is sufficient for a self-employed individual.


Dangerous Occurrences

These are incidents that could cause injury or illness to a worker. These are close-call incidents. Not all incidents need to be reported so you should consult the actual regulations to see if you need to fill out a RIDDOR report


Gas Incidents

A gas incident must be reported if it has caused the death of any individual. Additionally, a registered gas engineer must advise on any dangerous gas related issues that could cause the following:

  • The accidental leakage of gas
  • Incomplete combustion of gas
  • Inadequate removal of the product of gas combustion


Changes to Legislation in 2013

Since 2013 the following changes to the RIDDOR legislation have come into force:

  • The ‘major injuries’ classification has been replaced with a more refined list of ‘specified injuries’
  • The 47 types of industrial disease have been replaced with 8 categories of reportable work-related illnesses
  • Less ‘dangerous ‘occurrences’ now require reporting


After you have familiarised yourself with the situations where it is necessary to produce a RIDDOR report, the next step is to learn how to compose one should your business need to report an incident.
