Are worker health and safety representatives and JHSC worker members entitled under the OHS
Act to investigate incidents that do not result in deaths or critical injuries? - correct answer ✔✔-
NOTHING in the Act spells out what they can do to investigate incidents that don't result in
deaths or critical injuries
- Would want to investigate: harassment, violence, any situation that could escalate, an incident
(near miss), disabling injuries, etc.
What kind of situations other than deaths and critical injuries should be investigated? How can
representatives and JHSC members secure these rights? - correct answer ✔✔- Would want to
investigate: harassment, violence, any situation that could escalate, an incident (near miss),
disabling injuries, etc.
- Make a written recommendation so it doesn't happen again
- Negotiate as part of a collective agreement
,Critical Factors in the Investigative Process - correct answer ✔✔Incident investigations are
influenced by:
1- Timing: A critical factor in incident investigations. Time affects several types of information
2- Severity: Given that investigations are time-consuming, companies tend to examine only
those incidents that have the most serious consequences
3- Legal requirements: Certain types of events—those in which an injury requires medical aid or
results in lost time, for instance—must be reported to a Workers' Compensation Board,
normally within three days
Investigation Methods - correct answer ✔✔1- Observations or Walkthroughs
- Walkthrough refers to inspection of incident scene to get a picture of the total environment
2- Interviews: Basic Rules
- First thing to say "not doing this to cause any blame, doing this to prevent things from
happening again"
- Interview witnesses on the spot as soon as possible after the event
- Interview witnesses separately and in a neutral location
- Put the witness at ease
- Let the individual recall the event in his or her own way
- Ask necessary questions at appropriate times, without interrupting the speaker's train of
thought
- Give the witness feedback. "Based on what you said, this is my understanding of what you saw.
If there is something I missed or haven't got right, please add to or clarify it."
- Make sure that critical information—either from the witnesses or from your own observations
—is recorded in a timely fashion
- End the interview on a positive note by thanking the witness for his or her valuable time and
assistance
3- Re-enactments
, - Simulation designed to recreate circumstances leading up to incident
Guidelines for conducting a re-enactment:
1- A qualified observer is necessary
2- Do not show—tell
3- Shut down every energy source and lock them out
4- Carefully act out the events
Walkthrough, interview, and re-enactment can be supplemented by:
- Photographs, drawings, computers, tape measures, clipboards, water-resistant pens,
flashlights, record check
Domino Theory - correct answer ✔✔- Theory that every incident results from a series of events
developed by H.W. Heinrich
- All align up properly, all the dominos go down → accident → injury
- If you remove one of the dominos, it wouldn't have had the same result (all the dominos
would not have fallen down)
1- Background: A lack of control over the management function (planning, organizing, leading,
controlling)
2- Personal defects: Personal factors such as physical or mental problems, and job factors such
as normal wear and tear of equipment
3- Unsafe acts and conditions: (described earlier)
4- Incident: A series of undesired events with release of energies that can cause harm
5- Injury: The most undesired result (e.g., trauma or property damage)
The Swiss Cheese Model - correct answer ✔✔- Updated version of domino model presented
by J. Reason
- Series of dominoes with holes in them
