It’s important to remember when investigating an accident that effective permanent corrective action measures involve analysis and upgrade of process, as well as management procedures. See chart below for some of the areas to assess.

Reason for Accident		Corrective Process
Procedures	None developed Developed but not followed Developed but not understood Developed but not accurate	Procedure developed Employee instruction
Hazard	Created by external factors Created by co-worker Documented but not repaired Identified but accepted Unidentified Repaired by deficient repair	Supervisory recognition Supervisory intervention
Facilities/Equipment	Faulty equipment Poor design Corrosion/wear Ergonomic factors Facility layout New equipment Change in process/materials	Equipment maintenance Equipment repair Employee instruction Supervisory recognition
Communication	Insufficient planning Communication planning Confusion	Formal planning process Verification of communication
In a Hurry	Supervisor implied need Employee perceived need Friendly competition External factors Workload too heavy Lack of teamwork Rushes/Deadlines Equipment failure	Supervisor intervention
Training	Insufficient training Circumstances not addressed Tools used incorrectly	Formal training process Proficiency training
Other Factors	Weather/ Temperature Long work hours Physical overexertion Personal protective equipment Noise Visibility	Supervisory recognition Supervisory intervention
