Accident Ratios(1)
Heinrich's analysis of 75,000 industrial accident reports found,

1 Disabling injury
100 Minor injuries
500 Property damage accidents
Bird (1969)
(Whilst not strictly relevant for purposes here, an HSE/APAU
(see HSG96) case study pro
insight into property damage accidents. In an eighteen week
period on a construction site
workers, 3570 such accidents were recorded).

The actual figures above (often displayed in pyramids) relate
only to the Organisations/pprovided the data from which the ratios
were determined; ratios for other Organisation
generated from their own data.
Comment:
Whilst the sum total of an Organisation's accidents is
essentially unique, th
of outcome variables is not. In main stream sectors, the number
of acciden
in property damage has always exceeded those that result in
injury. As f
that result in neither injury nor damage (the near-miss
accidents), theymassively exceeded the combined total of both
property damage and inju
Consequently, an informed glance at an Organisation's accident
data can
about its general reporting culture.
(An additional and quite alarming variable exists to corrupt
analysis for the unwary but tha
continue in the members only area).

Industry tends to focus most of its efforts on reducing the

the pyramid; severity
tends to be the driver. Whilst they must be investigated, the
priority given
resulted in reduced attention lower down the pyramid. The
belief, prevaili
years, is that accident prevention capability is measurable via
injury statisti
it is a belief fuelled by a misunderstanding of terms.
The accident and the injury are two distinct...Read More
