Introduction l.jpg
Introduction

  • Most Frequent BGSU OSHA Recordable Injuries/Illnesses

    • Slips, trips and falls

    • Strains and sprains

    • Cuts

    • Struck by an object


Objectives l.jpg
Objectives

  • Types of accidents

  • Causes or contributing factors of accidents

  • How to perform an accident investigation

  • What documentation should be completed


Overview l.jpg
Overview

  • The failure of people, equipment, supplies or surroundings to behave or react as expected, causes most accidents.

  • Accident investigations determine how and why these failures occur.

  • Accident investigations are a tool for supervisors and accident investigation teams to find main causes of illnesses, injuries, and “near misses” allowing for corrective actions.


Overview5 l.jpg
Overview

  • Departments are encouraged to use the BGSU Accident Investigation Report Form as a method of reducing hazards in their areas.

  • The aim of an accident investigation should be to prevent recurrence of the same accident.


Definitions l.jpg
Definitions

  • Accident

    • An unplanned event that interrupts the completion of an activity that may or may not result in personal injury, illness or in property damage.

  • Near Miss

    • An unplanned event that interrupts the completion of an activity which directly involves the workers and does not result in personal injury, illness or in property damage.

  • Accident Investigation

    • The process of determining the causes of accidents and implementing corrective actions to prevent recurrence.


Types of accidents l.jpg
Types of Accidents

  • Minor Accidents

    • Accidents that cause minor injury/illness, requiring little or no treatment, or property damage.

  • Serious Accidents

    • Accidents that cause injury/illness or damage to equipment and/or property. If the accident is considered an OSHA recordable the accident is serious.


Outcomes of accidents l.jpg
Outcomes of Accidents

  • Negative

    • Injury, illness, or death, property and equipment damage, lost productivity, poor morale and $$$$$$.

  • Positive

    • Accident investigations

      • increase productivity, improve operations, raise awareness and prevent recurrence.

Who should perform the accident investigation l.jpg
Who Should Perform theAccident Investigation?

  • Dependent on the severity

    • Person involved

    • Supervisor

    • Environmental Health and Safety

  • The advantage of having a supervisor perform the investigation is the supervisor is likely to be the most knowledgeable about the work, the persons involved, and current conditions.

  • The supervisor can also take immediate remedial action.


Steps in an accident investigation l.jpg
Steps in an Accident Investigation

  • Initial Response

  • Information Gathering

  • Analysis and Conclusion

  • BGSU Accident Investigation Report


Step 1 initial response l.jpg
Step 1 - Initial Response

  • After an accident occurs, the initial response should be as follows:

    • Get treatment for individuals that may be injured.

    • Assure the safety of others.

    • Secure the site.

    • Complete the BGSU Injury/Illness Reporting Form.


Step 2 information gathering l.jpg
Step 2 – Information Gathering

  • Inspect the accident site and note information such as:

    • Positions of injured workers

    • Equipment and materials being used

    • Safety devices in use

    • Position on appropriate guards

    • Positions of controls of machinery

    • Damage to equipment

    • Housekeeping of the area

    • Weather conditions

    • Lighting levels

    • Noise levels


Step 2 information gathering19 l.jpg
Step 2 – Information Gathering

  • Gather information:

    • On procedures and rules for the area

    • On maintenance records and equipment involved

    • By taking photographs and making diagrams

    • From employees


Step 2 information gathering20 l.jpg

  • Interview

    • Injured person or persons

    • Witnesses

  • Isolate contributory factors

    • Would the accident have occurred if this particular factor was not present?

  • Determine

    • Why the accident occurred

    • A likely sequence of events and probably causes

  • Accident Tree Handout (Tab 1)

  • Example

    • Bad Report (Tab 2)

    • Better Report (Tab 3)

Step 3 – Analysis and Conclusion

  • Draw conclusions and make recommendations based on key contributing factors and causes.
