Heinrich's Pyramid
300=near misses 29=minor 1=major
Bird's Pyramid
600=near misses 30=property damage 10=minor 1=major
APOLLO Evidence Types Sensed= Inferred=
=5 senses =lab analysis, procedures, logs
Incident
An unintentional event may cause personal harm or other damage **removes human blame
How should you ask investigative questions??
Ask opened ended questions, directly after accident
APOLLO Root Causes
At least 2= 1 action + 1 Condition strong solutions= root causes

Causal Factors
Events that cause the accident *root causes *basic *immediate
FTA= LTA= FMEA=
Fault Tree Analysis Less Than Adequate Failure Modes and Effect Analysis

Conklin Safety Definition
Safety is not the absence of events; safety is the presence of defenses
Failure
Something that goes with the personnel, equipment, or environment
APOLLO Problem Definition
What=Primary Block(Effect)=Problem Why=caused by Where?? When??
TAP ROOT Event=
Who does what 1 action per event frequency x consequence
TAP ROOT Condition=
amply events
Steps following corrective actions=
develop corrective actions, track corrective, follow up
Root Causes
different meanings to everyone *1st cause *Last Cause * caused the accident
TAP ROOT Causal=
event or condition we can do something about and prevent incident
TAP ROOT corrective action=
lower frequency and consequence
Goal of accident investigation
reoccurance of the accident
Accident
sequence of events that produces unwanted injury, illness, death , or property
TAP ROOT Accident=
something happens that wasn't supposed to
Hazard
something that has the potential to cause injury
TAP ROOT Incident=
worst thing that could have or would have happened
