  1. The formula for calculating your accident frequency rate is the number of reported accidents multiplied by 200,000, divided by the number of employee hours worked. The number of reported accidents is derived from your operations, as is the total hours worked, while the number 200,000 is used in a number of safety KPI's to standardise the AFR ...

  4. Accident frequency rate is one of the standard safety measures which companies use to identify and analyse the number of occupational accidents which take place in the workplace. Any accident which is reported on site or in the workplace will become a part of the resulting AFR number. The reason for calculating an accident frequency rate is to ...

  5. Mar 1, 2024 · How are advisory fuel rates calculated? HMRC works out what the AFR should be by taking the average cost of a litre of unleaded or diesel fuel, and crunching these numbers with the official ...

  6. Jul 20, 2023 · Lambda is a dimensionless term used to describe the actual air-fuel ratio (AFR) in relation to the stoichiometric AFR. It is calculated by dividing the actual AFR by the stoichiometric AFR. For example, if the actual AFR is 15:1 and the stoichiometric AFR is 14.7:1, the lambda value would be 15/14.7 = 1.02.
