Definitions

Incident
An incident is an event that results in:
  • a lost-time accident and/or injury to personnel
  • damage to project equipment, facilities or property
  • impact to the public or environment
  • an emergency response or should have resulted in an emergency response.
Near-Miss
A near-miss is an event that, under slightly different circumstances, could have become an incident. Examples include:
  • any unintentional hydrogen release that ignites, or is sufficient to sustain a flame if ignited, and does not fit the definition for an incident
  • any hydrogen release which accumulates above 25% of the lower flammability limits within an enclosed space and does not fit the definition of an incident
Non-Event
A non-event is a situation, occurrence, or other outcome relevant to safety that does not involve a particular incident or near miss. For example, a non-event might consist of a failed safety inspection.

Navigation

The left navigation on the H2Incidents website is two-fold.

  1. Links
    By clicking on the links in the left navigation, you can view all incident reports matching that lone selection. For example, clicking on "Minor Injury" within the "Damages and Injuries" category will return a list of all incident reports that included "Minor Injury."
  2. Checkboxes
    Selecting checkboxes next to navigation items—then clicking the "Update Criteria" button—will provide a restrictive search on the criteria selected. Each selected checkbox will restrict the results to only incident reports that include that criteria. For example, selecting the checkbox next to "Minor Injury" in the "Damages and Injuries" category and selecting the checkbox next to "Decision Making" in the "Factors" category will return a list of all incident reports that included both "Minor Injury" and "Decision Making."
