Overall, calculating and monitoring safe man hours is a proactive approach to workplace safety, contributing to a safer work environment, improved compliance, and potentially lower operating costs.

Formula for "Safe Man Hours"

Meaning of "Safe Man Hours" is Total Hours worked by employees of a company without loss time incident (LTI).

Suppose in a company Total Hours worked by employees in one year is 10000 hours, then "Safe Man Hours" for the company will be 10000 hours.

Point to be Noted

If any accident happens in company then "Safe Man Hours" will be Zero, suppose in one year of period "Total Hours worked" is 10000 hours, but in same year one accident happens then "Safe Man Hours" will become zero, after the accident "Safe Man Hours" will be calculated from Zero.

How to calculate "Total Hours Worked"
