Mining – Safety Assessment


Safety Assessment Mining assesses the cognitive and psychomotor abilities needed for safe and productive working in the mining industry. The mining industry is a particularly hazardous working environment. Workers in the mining sector have a seven to ten times higher risk of a fatal accident at work than workers in other areas of industry. Accidents not only put individuals at risk but also represent an additional cost factor for the industry. It is for these reasons that managers often seek to reduce the risk of accidents through organizational measures and by selecting workers who are as safe and skilled as possible. Personal factors that can help to reduce accidents include experience, cognitive and psychomotor skills and safety-related personality characteristics.

The Safety Assessment Mining test set has been developed to provide a specific tool for the personnel psychological testing of transport drivers and machine operators in the mining industry. It can be used in both the selection and development of at risk operators. When assessing existing at risk workforce, often other performance data such as near misses or production rates, or post incident reports may be used to inform further areas of assessment.

In the course of a multi-year validation study the Safety Assessment Mining was administered to a large sample of machine operators and transport drivers in various mines in South Africa. Comparison of respondents’ test results and their accident frequency showed that the Safety Assessment Mining test set makes an important contribution to the prediction of accident frequency.





The Safety Assessment Mining test set comprises of the following dimensions and abilities:


Ability Definition

Duration in minutes

Reaction time

Capacity to process information and react swiftly such as during emergency situations (e.g. taking power out of a vehicle by braking hard)

approx. 6

Speed and movement anticipation

Capacity to anticipate speed and direction of moving objects to safely navigate around the mine site and to judge parking and braking distances to efficiently manoeuvre the truck for loading or unloading

approx. 9

Stress tolerance – Performance based

Capacity to respond to visual and auditory signals under varying time and/or cognitive pressure, using co-ordinated and simultaneous multi-limb responses (e.g. moving a vehicle in confined space)

approx. 15

Eye-hand coordination

Capacity to move hands simultaneously to operate control devices (e.g. dynamically adjust the control of a vehicle or machinery in response to changes in driving conditions)

approx. 6

Total length of the test set

approx. 36
