2. Dangerous occurrences
Dangerous occurrences are certain unintended, specified events, which may not result in a reportable injury, but which do have the potential to cause significant harm.
For an incident to be reportable as a dangerous occurrence, it must have, or could have, resulted in the release or escape of coronavirus leading to possible or actual exposure.
You are not required to do any complex analysis, measurement or test, but you should make a reasonable judgement as to whether the circumstances:
- gave rise to a real risk
- had the potential to cause significant harm.
Examples of a reportable dangerous occurrence
Assess each dangerous occurrence on a case-by-case basis.
Examples of reportable dangerous occurrences include:
- deliberately working with the virus: a laboratory worker smashing a vial containing coronavirus on the floor (outside a microbiological safety cabinet). This leads to people being exposed to the virus
- incidental exposure: a sample from a COVID-19 patient breaks in transit, leading to spillage and the driver becoming exposed
