What’s Dangerous Occurrence? Definition, Meaning & Examples

In the realm of workplace safety, understanding and reporting dangerous occurrences is crucial for preventing accidents and safeguarding lives. This comprehensive guide delves into the definition, meaning, and examples of dangerous occurrences, providing clarity on how they are identified, reported, and managed under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR).

A dangerous occurrence refers to specific unintended events or incidents that have a high potential to cause death or serious injury. While these incidents might not result in immediate harm, their potential impact necessitates timely reporting and investigation to prevent future occurrences. Dangerous occurrences are distinct from accidents in that they emphasize the inherent risk and potential for significant harm, rather than the harm itself.

Dangerous occurrences are governed by the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR). Under RIDDOR, certain incidents must be reported to ensure that enforcing authorities are informed about what happened and why. This reporting mechanism aids regulators and businesses in identifying hazards and implementing measures to prevent similar incidents in the future.

Schedule 2 of RIDDOR

Schedule 2 of RIDDOR lists the specific dangerous occurrences that must be reported. These are categorized based on the nature of the incident and the potential risks involved. Each type of dangerous occurrence is associated with paragraph numbers within the schedule, facilitating easy reference and accurate reporting.

Reporting dangerous occurrences serves multiple vital purposes:

  1. Informing Authorities: It allows enforcing authorities to understand the circumstances surrounding the incident, enabling them to take appropriate actions.
  2. Preventing Accidents: By analyzing reported occurrences, regulators and businesses can identify patterns and implement preventive measures to enhance workplace safety.
  3. Ensuring Compliance: Timely reporting ensures that organizations comply with legal obligations, avoiding potential penalties and fostering a culture of safety.

To determine whether an incident qualifies as a dangerous occurrence under RIDDOR, the following criteria must be met:

  1. Potential for Harm: The incident must have, or could have, resulted in the release or escape of a biological agent, such as the coronavirus (COVID-19), leading to possible or actual exposure.
  2. Real Risk: There must be a reasonable judgment that the circumstances gave rise to a real risk of significant harm.
  3. No Complex Analysis Required: Reporting is based on a reasonable assessment rather than complex analysis, ensuring swift and efficient reporting.

Understanding specific examples can clarify what constitutes a dangerous occurrence. Here are some illustrative scenarios:

1. Deliberate Work with Hazardous Substances

  • Scenario: A laboratory worker deliberately smashes a vial containing the coronavirus on the floor, outside a microbiological safety cabinet.
  • Potential Harm: This action leads to the release of the virus, exposing others to the pathogen and posing a significant health risk.

2. Incidental Exposure

  • Scenario: During the transit of a sample from a COVID-19 patient, the container breaks, causing a spillage.
  • Potential Harm: The spillage results in the driver being exposed to the virus, increasing the risk of infection.

3. Equipment Malfunction

  • Scenario: A breathing apparatus used by divers malfunctions, depriving them of oxygen.
  • Potential Harm: The malfunction can lead to hypoxia or other severe health consequences for the diver.

4. Lifting Machinery Failure

  • Scenario: The lifting equipment on a diving project collapses or fails, putting divers at risk.
  • Potential Harm: The failure could result in serious injury or death if divers are endangered by the malfunctioning machinery.

5. Explosion or Fire

  • Scenario: An unintentional explosion occurs in the workplace, involving gas cylinders.
  • Potential Harm: The explosion poses immediate threats of fire, structural damage, and injuries to personnel.

6. Pipeline Bursting

  • Scenario: A pipeline or part of it bursts or collapses unexpectedly.
  • Potential Harm: Such an event can lead to significant environmental damage, exposure to hazardous substances, and risks to human health.

Reporting Process

When a dangerous occurrence takes place, the responsible person—typically the employer—must report it to the enforcing authority promptly. The reporting process involves:

  1. Notification: Informing the authority by the quickest practicable means without delay.
  2. Detailed Report: Submitting a comprehensive report within 10 days of the occurrence, outlining the nature of the incident and the potential risks involved.
  • Dangerous Occurrences: Specific incidents with high potential for causing death or serious injury, requiring mandatory reporting under RIDDOR.
  • RIDDOR Compliance: Ensures that organizations report significant risks, enabling authorities to take preventive actions.
  • Simple Reporting: Focuses on making a reasonable judgment about the risk rather than conducting complex analyses, facilitating swift reporting.
  • Examples: Include deliberate actions leading to exposure, equipment malfunctions, explosions, and pipeline failures, among others.

Understanding and reporting dangerous occurrences is a fundamental aspect of workplace safety. By recognizing the types of incidents that qualify as dangerous occurrences and adhering to RIDDOR’s reporting requirements, businesses can play a pivotal role in preventing accidents and protecting lives. Prompt and accurate reporting not only ensures compliance with legal obligations but also fosters a safer and more secure working environment for everyone involved.
