What Does RIDDOR Stand For?

RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations, which is a bit of a mouthful, so it is usually shortened to RIDDOR.

You will have probably heard of RIDDOR because these health and safety regulations apply to pretty much all workplaces. But what does it mean? And what do you need to do?

Well, as the name suggests, the RIDDOR regulations are about the reporting of injuries, diseases and dangerous occurrences. This means that, if something bad happens at work, and someone is harmed, it may need to be reported under RIDDOR.

If an accident, injury, disease or dangerous occurrence happens, RIDDOR makes it a legal requirement to report it. Not in all cases, but anything that results in a trip to the hospital or a few days off work is likely to come under RIDDOR.

RIDDOR places duties on employers, self-employed and people in control of work premises, so it is important to know and understand what RIDDOR stands for so that you can make sure you comply.

What duties do you have under RIDDOR?

Well, as the name suggests, RIDDOR is about reporting injuries at work, and this includes...

  • Serious workplace accidents
  • Occupational diseases
  • Specified dangerous occurrences

RIDDOR applies at work, so it is only (other than certain gas related incidents) accidents that are work-related that need to be considered. An accident is work-related if any of the following was a factor:

  • The way the work was carried out
  • Any machinery, plant, substances or equipment used for the work or
  • The condition of the site or premises where the accident happened

Also, not all injuries are reportable. Accidents that only involve very minor injuries might not need to be reported. The regulations are specific on what needs to be reported, so let's take a closer look at what RIDDOR stands for.

The R in RIDDOR stands for Reporting.

RIDDOR is all about reporting. The regulations themselves specify what should be reported and when. In all cases, reports under RIDDOR should be made without delay. The enforcing authority (usually the HSE) may want to investigate.

  1. notify the relevant enforcing authority of the reportable incident by the quickest practicable means without delay; and
  2. send a report of that incident in an approved manner to the relevant enforcing authority within 10 days of the incident.
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 Schedule 1

The I in RIDDOR stands for Injuries.

These are deaths, specified injuries (such as fractures, amputations, crush injuries to the head or torso and serious burns), any injury that results in a worker being unable to perform normal work duties for more than 7 days, and injuries to non-workers which result in them being taken directly to hospital for treatment.

Without question, fatalities must always be reported under RIDDOR. Where any person dies as a result of a work-related accident, regardless of whether or not they are an employee.

Non-fatal injuries must also be reported. These could be one of the specified injuries, or any other injury resulting in the worker being unable to carry out normal duties for over 7 days.

Specified injuries to workers include:

  • Bone fractures
  • Amputations
  • Blindness or reduction in sight
  • Crush injuries to head or torso
  • Burn injuries
  • Scalping
  • Loss of consciousness
  • Hypothermia or heat-induced illness
  • Resuscitation
  • Hospital admittance

Where any non-worker is taken to hospital for treatment of an injury, it is also reportable under RIDDOR.

The D in RIDDOR stands for Diseases.

These are occupational diseases likely to have been caused or made worse by work, such as carpal tunnel syndrome, hand-arm vibration syndrome, occupational cancer, occupational dermatitis, tendonitis or severe cramp of the hand or forearm etc.

The DO in RIDDOR stands for Dangerous Occurrences.

These are near miss events that did not actually cause injury but could have resulted in serious injury. These are specified in the regulations and include the collapse of failure of lifts and lifting equipment, plant or equipment contact with power lines, the accidental release of dangerous substances, electric incidents causing serious fires and explosions etc.

7. Where there is a dangerous occurrence, the responsible person must follow the reporting procedure

The final R stands for Regulations.

That means that RIDDOR is a legal requirement. The reporting responsibilities must be complied with, by law. Usually, reports must be made within 10 days, for over 7-day incapacitation, within 15 days. Find out more about when you need to report in RIDDOR reporting timescales explained.

The HSE can (and do) prosecute for failing to report under RIDDOR. In 2018, a contractor was fined £2,700 for failing to report an injury within the specified timeframe.
