The Cumulative Safe Man Hours Calculator is a vital tool in workplace safety management. It helps organizations track the total number of man hours worked safely by subtracting hours lost due to injuries from the total man hours worked. Monitoring safe man hours is crucial for assessing safety performance and improving workplace conditions.
Formula
Safe Man Hours (SH) equals Total Man Hours (TMH) minus Lost Time Injury Hours (LTIH).
How to use
Enter the total man hours worked and the lost time injury hours into their respective fields. Click the “Calculate” button to get the cumulative safe man hours. Ensure all values are correct and that lost time injury hours do not exceed total man hours.
Example
If the total man hours are 5000 and lost time injury hours are 150, the safe man hours are 5000 – 150 = 4850. This indicates the amount of time worked without injury.
