4 steps in accident investigation
Step 1 Gathering the Information
Step 2 Analysing the information
Step 3 Identifying risk control measures
Step 4 Action plan and its implementation
STEP 1 - Gathering the information
Three main sources of info -
The scene
Witnesses
Documents
STEP 1 - The scene
Using photographs and videos to document the scene
Notepads to sketch the scene showing positions of people and equipment
Taking measurements of light, temperature
Finding out speeds of vehicles by looking at tyre marks (if involved)
Obtaining CCTV footage (if available)
Investigating the state of equipment (guards missing, worn parts)
STEP 1 - Interview technique
Interview as soon as possible after the event
Select suitable location for interview
Interview witnesses individually
Explain reasons for interview
Be polite, put witness at ease
Avoid leading questions
Ask open questions - where, when, what, who, how
Dont interrupt the witness
Record the interview
Repeat account to witness to ensure accuracy
STEP 1 - Documents
Gathering relevant information such as -
Risk assessments
Safe system of work
Training records
Maintenance records
Inspection records
Manufacturers data relating to equipment or substance
STEP 2 - Analysing causes
Immediate causes lead to - unsafe acts and/or unsafe conditions
STEP 2 - Unsafe acts
Operating without permission
Working at unsafe speed
Turning off safety devices
Using unsafe equipment
Failure to wear PPE
Horseplay between workers
STEP 2 - Unsafe conditions
Inadequate guarding on machines
Unsafe work processes
Hot, cold environments
Inadequate lighting
Holes in floor
Poor housekeeping
Underlying/ root causes…
Management failures
STEP 2 - Typical underlying/root causes
Failure to provide training
Failure to carry out risk assessments
Failure to allocate roles and responsibilities
Failure to carry out regular monitoring
Failure to provide adequate resources
Failure to select competent people
Failure to supervise staff
Failure to carry out maintenance at suitable intervals
Failure to regularly consult workers
STEP 3 - Identifying risk control measures
Based on analysis of underlying/root causes
Temporary, short term remedial action may be required
Permanent, long term remedial action should then be considered
Various controls should be assessed for reasonable practicability before a decision made as to which controls to implement
New controls should follow principles of prevention
