Result

Complete all fields with valid finite values and the specified units; denominators/durations must be positive. Cases/workers must be whole numbers.

Review the methodology and limits below before interpreting this result.

Example: 3 cases / 200,000 h = 3.00. Invalid: zero hours → no result.

Methodology & limits

DART = cases × 200,000 / hours

Count recordable cases involving days away, restricted work or job transfer, once per case. This is not a count of days. Use the same period and workforce as the hours.

Calculated at full precision; display rounded to two decimal places only.
