Number of accidents divided by time.
(No. of Reportable Accidents * 100,000) / Total No. of Hours Worked for all Employees = AFR
It depends to the acceptable risk level in your company. Usually AFR=10 is acceptable in most companies.
No. of Accident*(Ref.Value)/(total working man-hours)Ref. Value=100 (Number of worker) * 45 (number of working hours per week) * 50 (number of working weeks a year)Result = 225 000if you accept number of working hours per week=40result will be = 200 000
c=frequency x wavelength
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
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

500 manpower X 40 hours a week X 50 weeks per year = 1000000
Number of accidents divided by time.
An accident frequency rate is the number of accidents that occur within a specific company during a defined time period. This rate is often used to find areas within the company that require improvement in safety standards.
To calculate the equivalent property damage only (PDO) accident rate, you divide the number of PDO accidents by the total number of vehicle miles traveled (VMT) and then multiply by a standard factor, typically 1 million, to express the rate per million VMT. The formula is: [ \text{PDO Accident Rate} = \left( \frac{\text{Number of PDO Accidents}}{\text{Total VMT}} \right) \times 1,000,000. ] This provides a standardized measure to assess the frequency of property damage accidents relative to the amount of driving done.
calculation of lost time injury
The beat frequency is calculated by subtracting the frequencies of two sound waves. It represents the rate at which the amplitude of the resulting wave fluctuates.
