Be Prepared Develop a policy for accident investigation Routinely audit your policy to:
- ensure personnel understand their role
- system is driving corrective actions
- Assign responsibilities to personnel:
- employee must be trained to investigate
- investigator should know process

Conducting the Investigation Interview witnesses. Document the accident scene before any
changes are made. Review all information (procedures,
equipment manuals).

Conducting the Investigation Make documented observations on:
Pre-accident conditions Accident sequence Post-accident conditions
Document the facts (i.e.: location, witness remarks, and contributing factors).
Determine sequence of events leading to accident

Change Analysis A change analysis consists of:
Defining the problem Establishing the norm Identifying, locating, and describing the
change Identify what was affected and not affected List features of change Pick likely causes

Witness Interviews Interview promptly. Establish rapport with witness (treat as
equal). Get the facts. Write down the witness’s statement

Documentation Complete an accident investigation form to
collect: Personnel information Accident information (location, events
leading to accident, machines involved) Causes of the accident Recommendation to prevent accident Follow up information
![Page 16: 1 Accident Investigation 2 Objectives Explain the meaning and impact of accidents Identify different types of accident causes Know the purpose of accident.](https://reader036.fdocuments.in/reader036/viewer/2022082611/56649e185503460f94b052f9/html5/thumbnails/16.jpg)

Documentation From the accident investigation form and
witness statements write an accident investigation report. The report should include: Background information (where, who) Summary (sequence, extent, type, source) Analysis (causes) Recommendations
