Occupational safety, key indicators
Safety walks* (no)
LWIF contractor safety**
Serious accidents involving contractors*** (no)
TRIF employee safety****
*Safety walks carried out by Caruna’s employees on worksites and offices. The annual results are not comparable because since August 2015, when Caruna outsourced project supervision, the Safety Walks carried out by the project supervision have been reported as site inspections.
**The indicator reflects the ratio of occupational accidents to contractors or subcontractors while they work for Caruna or are within Caruna’s worksites, leading to a disability of at least one working day, in relation to working hours (incidents/million working hours).
***An accident leading to a disability of over 30 days or a permanent disability.
****The TRIF (Total Recordable Injury Frequency) reflects the ratio of occupational accidents to Caruna’s employees, leading to absences from work or requiring medical treatment visits, in relation to working hours (incidents/million realised working hours).
In 2016, Caruna’s own personnel did not have any occupational diseases.
