Are you measuring for zero accidents? Is this even possible? I agree it is a worthy goal. But, if you are presenting this to management, can you actually achieve it?
There is plenty of discussion around this issue. Maybe a better goal is something harder to measure, but more successful/beneficial in the long term. What about measuring one of these? (or a combination)
- response time from complaint to resolution (from employees)
- number of requests for safety related issues
- satisfaction of safety by workers (rate 1-10)
- safety committee interest & interaction
- decrease in airborne exposure levels year over year
- keeping track of engineering/administrative controls put in place per year
My 2 cents.
