Transcript of Accident Investigations

ACCIDENT INVESTIGATIONS -Help prevent future accidents
-To identify, correct and eliminate unsafe working conditions
-Reduce costs and downtime for employees, employers, supervisors, etc.
“The Accident Investigation is an essential prevention tool that makes it possible to determine the cause of an accident and minimize risks. Investigation means saving lives!”
• Need to have an open mind
• the accident investigators gather information, analyze it, draw conclusions, and make recommendations
• 1. Physical Evidence
o safety devices used
o machines/chemicals being used
o lighting levels
o time of day
o positioning of guards
• 2. Eye Witness Accounts
o interview witnesses: they may have a different story
o Ask open ended questions to get more information Where it happens (In theatre) - Hazards are everywhere in the shop, and all the power tools can easily cost injury which will be investigated.
- Load in, strike and during performance will be considered under on stage. Workers can be injury while setting up the stage. Performer can be injury during performance, for example, bump into the set or hurt them self by strain their muscles.
- Workers can burn them self by using the iron incorrectly in wardrobe
- During rehearsals, performers can strain their muscles just like on stage, in the rehearsal hall Why get involved? -The point of on accident investigation is to find out why it happened and what precautions can be put in to prevent it from reoccurring

-“To fulfill any legal requirements”

-To figure out the cost of the accident

-To determine proper safety regulations

-Look for the root cause. It can uncover other issues and precautions to take The cause of an accident: Task:
Identify the actual work being done at the time.
Were the appropriate tools and materials used and available at the time of the incident?
Were safety devices used properly?

What material was used during the time of the accident?
Was it poor training or a poorly designed machine?
Was it hazardous? Environment:
Sudden changes to the environment can affect the workplace and cause an accident.
Was it poor housekeeping?

The physical and mental condition of the worker is important to know. The worker may have been tired or ill or not properly trained.

Was management doing their job?
Did they enforce safety rules?
Were inspections carried out?
Was management properly trained? How are facts collected? -An accident is defined as “an unplanned event that interrupts the completion of an activity, and that may (or may not) include injury or property damage”

-The point of on accident investigation is to find out why it happened and what precautions can be put in to prevent it from reoccurring
In some events, witnesses may be the primary source of information since you may be unable to examine the scene immediately after the event.

Often, witnesses may be under severe emotional stress depending on the situation or may be afraid to speak up in fear of retaliation; therefore, sometimes conducting interviews is the hardest task. “What is an accident investigation?” Why it is important? What kind of accidents? -All accidents, occupational diseases and hazardous occurrences effecting any of the employers workers. Different kinds of hazardous occurrences -Minor injury: Medical attention is received at a medical treatment facility
-Disabling injury: An injury resulting in time loss
-Loss of Consciousness: Can be from electric shock or a toxic or oxygen deficient atmosphere
-Rescue/Revival or other emergency procedures: Requires emergency procedure to be implemented How it gets investigated -Reporting the accident
-First aid & medical care
-Advise investigators
-Identify causes
-Report findings
-Implement corrective action
-Evaluate effectiveness
-Make changes for continuous improvement The End When it comes to accident investigations, we always want to ask... This way, information can be collected and the reason for the accident can easily be determined! Who Was Involved? In most cases, you want to ask whether or not were involved. EYEWITNESSES Eyewitnesses: Any individuals that watched the event occur, but were not directly injured in the situation. While there may be cases in which witnesses exist… for those events that witnesses exist, use every effort possible to them. Don’t give up any opportunities as this will often result in helping to find the main cause of the accident!! DO NOT DO interview INTERVIEWS Therefore... Things to keep in mind when conducting interviews...
*Witnesses should be kept apart and interviewed as soon as possible. If witnesses discuss the event among themselves, individual perceptions may be lost and biased opinions may result.
*Witnesses should be interviewed alone. The decision of interviewing the witness at the scene of the accident or a quiet area depends on the nature of the accident and the mental state of the witness. Before we determine who may be involved in an accident investigation... Let us first establish... WHO INVESTIGATES? In Canada, certain authorities require that the investigation must be conducted by both management and labour representatives. Investigators should be knowledgeable about the work processes depending on the event. So in relation to theater, the investigator would have to be educated about theater-related work practices! In most cases... The supervisor should help investigate the event, but other members that may be involved include, but are not limited to: *employees with knowledge of the work
*safety officer
*health and safety committee
*union representative, if applicable
*employees with experience in investigations
*"outside" expert
*representative from local government Common Interview Questions When it comes to asking questions, you always want to ask open-ended questions! While questions will vary depending on the situation, here are just a few that are commonly used. . . *Where were you at the time of the accident?

*What were you doing at the time?

*What did you see, hear?

*What were the environmental conditions (weather, light, noise, etc.) at the time?

*What was (were) the injured worker(s) doing at the time?

*In your opinion, what caused the accident?

*How might similar accidents be prevented in the future? Citations Canadian Centre for Occupational Health. (2006). Accident Investigation: OSH Answers,

* Every accident , occupational disease and other hazardous occurrence that may effect an employee must be investigated.
