Serious Injury Fatality, Event Categorization, GRI

1. Event Classification & Categorization

2. Why are we doing this? Despite low overall incident rates, [COMPANY] continues to experience a stable rate of High-Consequence Injuries (HiC). Fewer injuries create a data gap, making it harder to predict Serious Injury or Fatality (SIF) events. Not all incidents carry the same risk for HiC, so it's essential to focus on identifying and preventing High-Potential Incidents (HiPo). This policy aligns with Global Reporting Initiative (GRI) 403.2018 guidelines on occupational health and safety to strategically reduce the risk of SIF occurrences.

3. Terms High Hazard Work Type (HHWT) Work types or conditions known as precursors to serious injuries and fatalities. Serious Injuries and Fatalities (SIF) is a serious work-related injury from which the worker cannot recover or is not expected to fully recover to pre-injury health status within six months. Work-Related An event is work-related if an event or exposure in the work environment either caused or contributed to the event. High Consequence Injury (HiC) A work related Serious Injury and Fatality (SIF) or and injury that occurs during a High Hazard Work Type (HHWT) High Potential Incident (HiPo) A work-related incident when the exposure could have reasonably and realistically resulted in a Serious Injury or Fatality (SIF) outcome had any of the circumstances, factors, or protective measures changed and does not meet the threshold for High Consequence Injury (HiC)classification

4. High Hazard Work Types Lockout Tagout – control of energy Hoses under Pressure – connecting/disconnecting Permitted Work - Hot Work, Confined Space, Line Break, or Specialty Permits Working At Height - if there were no precautions in place, a person could fall a distance liable to cause personal injury Barricades & Machine Guarding - Guards are barriers that prevent access to danger areas: fixed, interlocked, adjustable, and self-adjusting. Arc Flash – NFPA 70E - A release of thermal energy from an electric arc by the vaporization and ionization of materials Impairment – Conditions including substance use/chemical impairment, stress/trauma, fatigue, certain medical conditions, mental distress, or exposure to extreme conditions. Working Under A Suspended Load - the area including, but not limited to, the area directly beneath the load in which it is reasonably foreseeable that partially or completely suspended materials could fall in the event of an accident Bypassing A Safety Device - an operation that temporarily stops a component of a system or stops the entire system.
