Hi All, Just doing some looking around the web for similar companies that publish their own rates (been asked to look at comparisons). Now maths is by no means my strong point and I am looking at data published by the Hs2 project, can someone who is a lot smarter than me, explain how they get a rate lower than zero? Thank you

I did a bit more digging, its something to do with rating accident type in terms of seriousness when you do the calculation. Apprently its a better way https://safety.hs2.org.uk/how-were-performing/

Well obviously it's a totally brilliant way if it gets your rate below zero. Zero harm is evidently old hat, less than zero is the new aim!

None of the several frequency rates I see on that page are below zero though. The lowest of them is 0.06. An accident rate below zero would have a minus sign in front of it and would be calculated in a truly innovative way.

Did someone think about doing some work, then decided against it resulting in a negative number of hours worked. So accident numbers multiplied by whichever number you use ( 100,000 or 200,000) gives a positive number. A positive number divided by a negative one gives you a negative rate. Obviously, the number of accidents can not be zero for this to work.
