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

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.

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. The elements of the Army Systems Model are:
