Total number of accidents multiplied by one million and divided for total worked hours.
AF= (Number of accidents * 1x10^6)/Worked Hours
Total number of accidents - Accidents that had result in absence to work. That had originated lost days.
Total worked hours - Number of worked hours done by all employees in that period. Incluing extra hours of work, excluding holidays, etc.
I Din't Know
(No. of Reportable Accidents * 100,000) / Total No. of Hours Worked for all Employees = AFR
A lower accident frequency rate is better as "frequency" means "how often something occurs".
accident frequency rate = accidents with lost time x 1.000.000 / manhours worked
500 manpower X 40 hours a week X 50 weeks per year = 1000000
You can calculate a wave's frequency by dividing the speed of the wave by its wavelength. The formula is: frequency = speed of wave / wavelength.
c=frequency x wavelength

fatal accident rate is number of fatal accidents x 100,000 divided by the total hours worked. Accident incident rate is the total number of accidents x 100,000 divided by the total hours worked. accident severity rate is the total days lost x 1,000 divided by the total hours worked
Number of accidents divided by time.
speed=frequency x wavelenth xD
