Heinrich’s Theorems
INJURY - caused by accidents.
ACCIDENTS - caused by an unsafe act –
injured person or an unsafe condition –
work place.
UNSAFE ACTS/CONDITIONS - caused by
careless persons or poorly designed or
improperly maintained equipment.
FAULT OF PERSONS - created by social
environment or acquired by ancestry.
SOCIAL ENVIRONMENT/ANCESTRY - where
and how a person was raised and educated.

How accidents are caused &
how to correct those causes.
Parallels Heinrich's to a point.
Injury is called RESULT, indicating it could
involve damage as well as personal injury
and the result can range from no damage
to the very severe.
The word MISHAP is used rather than Accident
to avoid the popular misunderstanding that an
accident necessarily involves injury or damage.
Finally, the term OPERATING ERROR is used
instead of Unsafe Act & Unsafe condition.

Operating Errors:
Being in an unsafe position
Stacking supplies in unstable
stacks
Poor housekeeping

ACAC1717
Initial studies show for each disabling injury,
there were 29 minor injuries and 300 close
calls/no injury.
Recent studies indicate for each serious result
there are 59 minor and 600 near-misses.

There are seven avenues through which
we can initiate countermeasures. None
of these areas overlap. They are:
Safety management error
Safety program defect

A system is simply a group of interrelated parts
which, when working together as they were
designed to do, accomplish a goal. Using this
analogy, an installation or organization can be
viewed as a system.
