RIDDOR and First Aid Explained: When Must Injuries Be Reported to HSE?
4 min reading time
Many employers understand that workplace injuries must be recorded. Fewer are clear about when an incident must also be formally reported to the Health and Safety Executive (HSE) under RIDDOR.
This guide explains what RIDDOR is, which incidents are reportable, how it connects to first aid provision, and what employers in the UK need to understand.
The information below is general guidance and does not replace official HSE advice or legal consultation.
What is RIDDOR?
RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations.
It requires certain serious workplace incidents to be formally reported to the HSE. Not every injury is reportable, and first aid treatment alone does not automatically trigger a report.
Does every first aid incident need reporting under RIDDOR?
No.
Most minor injuries that are treated with basic first aid do not need to be reported to HSE.
RIDDOR applies only to specific types of serious injuries, occupational diseases, and dangerous occurrences.
What types of injuries are reportable?
The following are examples of injuries that may require reporting:
Fractures (excluding fingers, thumbs and toes)
Amputations
Serious burns
Loss of sight or permanent reduction in sight
Crush injuries leading to internal organ damage
Loss of consciousness caused by head injury or asphyxia
In addition, injuries that result in a worker being unable to perform their normal duties for more than seven consecutive days may also be reportable.
If an employee cannot perform their normal work duties for more than seven consecutive days following an injury, the incident may be reportable under RIDDOR.
This includes weekends and non-working days.
Dangerous occurrences
RIDDOR also covers certain “near miss” events known as dangerous occurrences.
Examples may include:
Collapse of lifting equipment
Explosion or fire causing significant disruption
Structural collapse
These may be reportable even if no one was injured.
How does RIDDOR connect to first aid provision?
First aid provision helps manage injuries immediately. However, if an incident meets RIDDOR thresholds, employers must take additional reporting steps.
Inadequate first aid arrangements do not automatically trigger RIDDOR, but serious consequences arising from poor management may lead to regulatory scrutiny.
