What are some real proportions I could use to compare 12 injuries across
9,900,000 hours of service. 1 per 800,000 hours with same statistics that
others would relate in real terms or relationships.. Thanks... |

How about 1 injury every 91.26 years? |

Oops, make that 94.12 years (using the original 9,900,000/12,
instead of 800,000). |

How about person years of work time?

I think it might help to consider a workforce or population size.
9,900,000 hours of service represents close to 4950 worker-years. The 12
injuries would therefore represent 2.424 injuries per year per 1000
employees.
