RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013)

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) [1] require employers and others in control of work premises to report and record accidents and certain other incidents. Changes to the regulations came into force in 2013.

It is a legal requirement for the following incidents to be recorded and reported to the Health and Safety Executive (HSE) [2-5]:

• Deaths of workers and non-workers due to work-related accidents (not suicides).
• Specified injuries to workers. These include:
  • fractures, 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, where an injury arising from an accident at work prevents someone carrying out their normal duties for more than seven consecutive days (excluding the day of the accident).
• Injuries to non-workers (e.g. members of the public), where a person is taken directly from the scene of an accident to hospital for treatment for that injury. There is no need to report incidents where people are taken to hospital purely as a precaution when no injury is apparent.
• Reportable occupational diseases. These 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.
• Dangerous occurrences, where injury does not occur but could have done, for example, explosion of a pressure vessel, an electrical fire, or if an employee is injured by a sharp known to be contaminated with a blood-borne virus (e.g. Hepatitis B or C, or HIV).

When an employee is injured by a sharp known to be contaminated with a blood-borne virus (BBV), this is reportable as a dangerous occurrence. When the employee receives a sharps injury and a BBV acquired by this route sero-converts, this is reportable as a disease. If the sharp is not contaminated with a BBV, or the source of the sharps injury cannot be traced, it is not reportable, unless the injury itself causes an over-seven-day injury. If the employee develops a disease attributable to the injury, then it must be reported [3]. See also Occupational Exposure Management (including Sharps).

Recording and reporting to the HSE must be made by the ‘responsible person’ [6]: for incidents involving members of staff the responsible person is the employer; for incidents involving self-employed persons working on the premises, or members of the public affected by work carried out on the premises which results in death or removal to a hospital for treatment, the responsible person is the person in control of the premises at the time of the incident.

All incidents must be reported to the HSE using the appropriate online form [7].

NB: the telephone service (0345 300 9923) is for reporting deaths and specified injuries only.

• Deaths, specified injuries and injuries to non-workers requiring hospital treatment should be reported without delay.
• Over-seven-day* injuries must be reported within 15* days of the incident occurring.
• Work-related diseases should be reported as soon as a doctor’s notification has been received.
• Dangerous occurrences should be reported immediately.

Recording of incidents covered by RIDDOR is important for ongoing monitoring, risk management and inspection. Records of all reportable injuries, diseases or dangerous occurrences must be entered into a data protection compliant accident book (BI510).  The HSE will also send a copy of the record held within their database following receipt of a report. In addition, records of any occupational accident that resulted in the worker being absent for more than three consecutive days (not counting the day of the accident but including any weekends or other rest days) must be kept but need not be reported unless extending to seven days.

*Since April 2012 reporting of over-three-day injuries was increased to over-seven-day injuries, and the reporting deadline increased from 10 to 15 days from the day of the accident.
