Investigate All Incidents and Accidents
Conduct and document an investigation that answers:
• Who was present? • What activities were occurring?• What happened?• Where and what time?• Why did it happen?
How Do You Investigate??
How To Investigate – Main Steps• Develop a plan• Assemble an investigation
kit• Investigate all incidents
and accidents immediately
• Collect facts• Interview witnesses• Write a report
Tips for Developing An Accident Investigation Plan
• Develop your action plan ahead of time.• Your plan might include:• Who to notify in the workplace?• How to notify outside agencies?• Who will conduct the internal
investigation?
Tips for Developing a Plan (continued)
• What level of training is needed?• Who receives report?• Who decides what corrections will be taken and
when?• Who writes report and performs follow up?
What Should Be in The “Investigation Kit”• Camera • Tape recorder• Gloves• Tape measure • Large envelopes• High visibility tape • Scissors• Personal protective equipment• First aid kit Report Forms
Root Cause Analysis
• Direct Cause – Unplanned release of energy or hazardous materials
• Indirect Cause – Unsafe acts and/or unsafe conditions
• Root Cause – Policies and decisions, personal factors, environmental factors
The Five Whys
Basic Question - Keeping asking “What caused or allowed this condition/practice to occur?”
The “five whys” is one of the simplest of the root cause analysis methods.
5 Whys In ActionSuzy had an unwitnessed trip and fall accident:
1)Why? She wasn’t looking where she was going2)Why? She was carrying a box3) Why? She was wearing inappropriate shoes4) Why? There was water on the ground5) Why?
Begin Investigation Immediately
• It’s crucial to collect evidence and interview witnesses as soon as possible because evidence will disappear and people will forget.
Fact Finding• Witnesses and physical evidence• Employees/other witnesses• Position of tools and equipment• Equipment operation logs, charts, records• Equipment identification numbers• Take notes on environmental conditions, air quality • Take samples• Note housekeeping and general working environment• Note floor or working surface condition• Take many pictures• Draw the scene
Interview Witnesses
• Interview promptly after the incident• Choose a private place to talk• Keep conversations informal• Talk to witnesses as equals• Ask open ended questions• Listen. Don’t blame, just get facts• Ask some questions you know the answers to
Write The Report• Who• What• Where • When• Why – Root Cause• Prevention & Action Steps• Follow through
Case Study #1• Handout to be provided
Case Study #1 - Findings• Morale a result of poor supervision &
management
Case Study #2
• Eye Injury• Investigation results: wasn’t following safety
protocol; training provided on correct chemical handling
• Action steps:– Disciplined employee for failing to follow safety
protocols
Case Study #3
• Bus Driver Crashes Bus While Texting• Investigation:– Employee trained not to text– Employee observed texting on run in the am– Letter of reprimand at end of am shift for texting– Accident in pm while texting
