ART Tool (assessment of repetitive tasks)

Observe the movements of the arms and select the category that is most appropriate.

Observe the movement of the arm and hand (not fingers) and count the number of times the same or similar pattern of motion is repeated over a minute.

Using the guide and ask the operative to establish the level of force required to complete the task. If a very strong force is required then changes are required before continuing the assessment.

Determine the amount of time that the worker spends in the postures described below. This includes the time spent moving to a bent or twisted position repetitively and the time spent holding a bent or twisted position.

The arm is considered to adopt an awkward posture if the elbow is raised to around chest height and the arm is unsupported (eg not resting on a workbench).

The wrist is considered to be bent or deviated if an obvious wrist angle can be observed.

Hand/finger grip

Determine the maximum amount of time that individuals perform the repetitive task without a break. Breaks are significant changes or pauses (eg of at least 5-10 minutes) in arm or hand activity. They include structured breaks such as meal breaks. They also include time spent performing other tasks that do not involve similar repetitive arm movements (eg a visual inspection task).

Speak to the workers about any difficulties they might have keeping up with the work. Select the most appropriate category.

Identify any other factors that are present in the task. For example.
- gloves affect grip and make handling the task more difficult.
- a tool (eg hammer, pick) is used to strike two or more times a minute.
- the hand is used as a tool (eg hammer) and struck ten or more times per hour.
- the tools, workpiece or workstation cause compression of the skin.
- the tools or workpiece cause discomfort or cramping of the hand or fingers.
- the hand/arm is exposed to vibration.
- the task requires fine precise movements of the hand or fingers.
- operators are exposed to cold drafts or grip cold tools.
- lighting levels are inadequate.

Psychosocial factors are not given a score. However, they should be considered through discussion with workers and if present in the workplace be recorded below. They include things such as:
- little control over how the work is done.
- incentives to skip breaks or finish early.
- monotonous work.
- high levels of attention and concentration.
- frequent tight deadlines.
- lack of support from supervisors or co-workers.
- excessive work demands.
- insufficient training to do the job successfully.
