Understanding RIDDOR


The Importance of RIDDOR in Workplace Safety

When it comes to workplace safety, the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations, commonly known as RIDDOR, plays a pivotal role. This regulation mandates that certain workplace incidents be reported to the relevant authorities, ensuring they are addressed appropriately and that steps are taken to prevent future occurrences. Whether you’re a seasoned safety professional or just getting acquainted with workplace safety regulations, understanding RIDDOR is essential.

What Does RIDDOR Stand For?

RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations. It applies to employers, the self-employed, and those in control of work premises, requiring them to report specific types of workplace incidents. Here’s a breakdown of what RIDDOR encompasses:

  • Reporting
  • Injuries
  • Diseases
  • Dangerous Occurrences
  • Regulations

This framework ensures that incidents are properly categorised and managed, which is crucial for maintaining a safe working environment.

A Brief History of RIDDOR

The introduction of RIDDOR was driven by the need for a systematic approach to reporting workplace incidents, ensuring that serious accidents and occurrences were properly documented and investigated. Before RIDDOR, there was no comprehensive legal requirement for reporting such incidents, which led to inconsistent practices and gaps in data regarding workplace safety.


RIDDOR was first introduced on 1st April 1986 under the name RIDDOR 1985. This initial version established the foundation for the mandatory reporting of workplace incidents. The primary reasons for its introduction included:

  • Improving Workplace Safety: By ensuring that all significant incidents were reported, RIDDOR aimed to create a safer work environment across various industries.
  • Data Collection: To gather accurate data on workplace accidents and diseases, which could then be used to identify trends, causes, and preventive measures.
  • Regulatory Oversight: Providing authorities with the information needed to oversee and enforce workplace safety regulations effectively.


RIDDOR was updated ten years later to RIDDOR 1995, which took effect on 1st April 1996. This update aimed to refine the reporting process, making it more comprehensive and user-friendly. Key changes included:

  • Expanded Reporting Requirements: The update included more detailed criteria for what needed to be reported, covering a broader range of incidents and conditions.
  • Simplified Procedures: Efforts were made to simplify the reporting procedures, making it easier for businesses to comply with the regulations.


The most recent update, RIDDOR 2013, has been in force since 1st October 2013. This version further streamlined the reporting process and addressed emerging risks in the modern workplace. Significant changes included:

  • Revised Incident Categories: The categories of reportable incidents were revised to focus on the most serious types of injuries, diseases, and dangerous occurrences.
  • Clarified Definitions: Clearer definitions and guidance were provided to help businesses understand their reporting obligations.
  • Improved Reporting Tools: The update introduced more efficient tools for reporting incidents, including online reporting options.

The Purpose of RIDDOR

The primary objective of RIDDOR is to ensure that serious workplace incidents are reported to the relevant authorities, such as the Health and Safety Executive (HSE), local authorities, and the Office for Rail Regulation (ORR). This reporting helps:

  1. Promote Workplace Safety: By mandating the reporting of certain incidents, RIDDOR encourages businesses to maintain safe working environments.
  2. Prevent Future Incidents: Detailed reporting helps identify patterns and causes of incidents, enabling preventive measures.
  3. Ensure Legal Compliance: Adherence to RIDDOR is a legal requirement, and failure to comply can result in significant penalties.

Duties and Responsibilities Under RIDDOR

RIDDOR places specific duties on employers, self-employed individuals, and those in control of work premises to report certain types of incidents. Here’s what you need to know:

Any injury that results in a worker being incapacitated for more than seven consecutive days must be reported. This includes:

  • Fatalities: Any death resulting from a work-related incident.
  • Specified Injuries: Fractures (excluding fingers, thumbs, and toes), amputations, serious burns, loss of consciousness due to head injury or asphyxia, and injuries that prevent normal work duties for more than seven days.
  • Injuries to Non-Workers: Any injury to non-workers that results in them being taken directly to a hospital for treatment.

Certain occupational diseases must be reported under RIDDOR. These include:

  • Carpal Tunnel Syndrome: Often caused by repetitive motion or vibration.
  • Occupational Asthma: Triggered by exposure to substances in the workplace.
  • Hand-Arm Vibration Syndrome: Caused by prolonged use of vibrating tools.
  • Occupational Dermatitis: Resulting from exposure to harmful substances.
  • Tendonitis or Severe Cramp: Caused by repetitive strain.
  • Occupational Cancers: Linked to exposure to carcinogens in the workplace.

Dangerous Occurrences

Dangerous occurrences, or near-misses, are incidents that could have led to serious injury or death but did not. These must be reported to help prevent future incidents. Examples include:

  • Collapse of Lifting Equipment: Failure of lifts or other lifting equipment.
  • Explosions and Fires: Incidents caused by electrical faults or chemical reactions.
  • Release of Dangerous Substances: Accidental release of substances that could harm health.
  • Contact with Overhead Power Lines: Incidents involving contact with live electrical wires.

RIDDOR is underpinned by a robust legal framework that outlines the requirements for reporting and the consequences of non-compliance. Key aspects of RIDDOR legislation include:

  • Mandatory Reporting: Specific incidents must be reported within defined timeframes, usually without delay.
  • Record Keeping: Businesses must maintain detailed records of incidents for at least three years.
  • Penalties for Non-Compliance: Failure to comply with RIDDOR can result in fines and legal action. For instance, in 2018, a contractor was fined £2,700 for failing to report an injury within the specified timeframe.

Steps to Ensure Compliance

Ensuring compliance with RIDDOR involves several key steps. By following these guidelines, businesses can create a safer workplace and avoid legal repercussions.

Educate and Train Staff

1. Comprehensive Training Programs:

  • Develop training modules that cover the essentials of RIDDOR, including what constitutes a reportable incident, the procedures for reporting, and the importance of accurate and timely reporting.
  • Incorporate real-life examples and case studies into training sessions to illustrate the types of incidents that need to be reported and the consequences of failing to do so.

2. Regular Refresher Courses:

  • Schedule regular refresher courses to keep employees updated on any changes to RIDDOR regulations and to reinforce the importance of compliance.
  • Use these sessions to address any questions or concerns employees may have about the reporting process.

3. Tailored Training for Different Roles:

  • Provide specific training tailored to different roles within the organisation. For instance, managers and supervisors should understand their additional responsibilities in overseeing and verifying reports.

Establish Clear Reporting Procedures

1. Develop a Reporting Protocol:

  • Create a clear and concise protocol for reporting incidents. This should include step-by-step instructions on how to document and report incidents, who to notify, and the required timeframes.

2. Designate Responsible Personnel:

  • Assign specific individuals or teams responsible for handling incident reports. Ensure they are well-trained and have the authority to act promptly.

3. Implement User-Friendly Reporting Tools:

  • Utilise digital tools and software to simplify the reporting process. Online forms and incident management systems can streamline the process and ensure that reports are submitted accurately and on time.

4. Communicate Procedures to All Staff:

  • Ensure that all employees are aware of the reporting procedures. This can be done through regular communication, posters, and easy-to-access resources on the company’s intranet.

Maintain Accurate Records

1. Detailed Incident Logs:

  • Keep comprehensive logs of all reported incidents. These logs should include details such as the nature of the incident, the individuals involved, the date and time, and any actions taken.

2. Secure Storage:

  • Ensure that records are stored securely and are easily retrievable when needed. Digital records should be backed up regularly, and physical records should be stored in a safe and organised manner.

3. Regular Review and Audits:

  • Conduct regular reviews and audits of incident records to ensure accuracy and completeness. This can help identify any gaps in reporting and provide insights into areas for improvement.

4. Compliance Monitoring:

  • Monitor compliance with record-keeping requirements to ensure that all incidents are documented correctly and within the required timeframes.

Regular Audits and Inspections

1. Schedule Routine Inspections:

  • Conduct routine inspections of the workplace to identify potential hazards and ensure that safety measures are in place. These inspections should be documented and followed up with corrective actions if necessary.

2. Perform Compliance Audits:

  • Regularly audit compliance with RIDDOR regulations. This includes reviewing incident reports, checking that all required incidents have been reported, and verifying that records are up to date.

3. Engage External Auditors:

  • Consider engaging external auditors to provide an objective assessment of compliance. They can offer valuable insights and recommendations for improving safety practices and reporting procedures.

4. Continuous Improvement:

  • Use the findings from audits and inspections to continuously improve safety practices and reporting procedures. Implement corrective actions promptly and ensure that lessons learned are communicated to all relevant staff
