ORCA is the acronym of Occupational Risk Calculator and is a method to assess hazards at work. It is a model that calculates occupational risks, similar to the calculation of risks for external safety. It provides insight into relative risks at work and can be used to draw conclusions about absolute risks at work.
Risk assessments are used by companies to identify the risks
within their organisation. However, no method was available to
quantify and prioritize these risks. ORCA (Occupational Risk
Calculator) provides the quantification and prioritization.
ORCA is based
on three databases that were developed and constructed,
commissioned by the Ministry of Social Affairs and Employment.
These databases contain information about:
- (underlying) causes of serious accidents that are reported to
and investigated by the Labour Inspectorate (also available in a
stand alone application called Storybuilder),
- exposure to hazards and the quality of working conditions that
affect the risk,
- cost and effectiveness of measures to reduce risk.
The model predicts probabilities of an accident with serious
consequences, which are fatality, permanent injury or recoverable
injury with hospitalisation within 24 hours.
