Overview

In this thought starter, learners are introduced to eight common workplace hazards, including those involving electricity, chemicals, and mechanical dangers. 

After reading short briefing sheets on each hazard, learners are invited to apply a set of criteria focused on the impact of each hazard to help them assess, prioritize, and rank those that most urgently need to be addressed.

Instructions

What you'll need

  • "Ranking workplace safety hazards" slideshow

Per student:

  • "Workplace hazards" briefing sheets
  • "Workplace hazards" student worksheet
  • "Workplace hazards ranking ladder" worksheet
  • "Ranking Workplace Safety Hazards" slideshow 

For groups:

  • Chart paper 
  • Markers

Learning Launch

  1. Slide 2- Present learners with a list of the eight common workplace hazards from the briefing sheets. Ask them to sort the hazards into three broad categories: electrical hazards, chemical hazards, and mechanical hazards (individually, in pairs, or in small groups).
  2. Slide 3- Invite learners to select the five hazards they believe are of greatest concern and therefore most in need of being addressed. 
  3. Encourage learners to share their reasoning for the hazards they selected and/or to explain their thinking about why the three hazards they left off their list were of lesser concern.


Developing Understanding

  1. Considering learners’ explanations for their selections, propose a set of criteria that can be used to determine which hazards are in most need of being addressed. Criteria could include: 
    • breadth of impact – how many people may be affected by the hazard and how widely it occurs across different workplaces or situations.
    • duration of impact – how long the effects of the hazard may last, including whether injuries or consequences are short-term or long-term. 
    • depth of impact – how serious the potential harm could be, including the risk of severe, life-altering, or life-threatening injury.
  1. Slide 4- Provide learners with copies of the eight workplace hazard briefing sheets and the Workplace Hazards Worksheet. Instruct them to carefully read the details provided on the briefing sheets and record relevant evidence under each criterion on the worksheet. 
  2. Slide 5- As learners consider the details of each workplace hazard through the lens of the criteria, have them rate the level of concern from 4 (very high concern)  to 1 (limited concern).


Reflect and Revise

  1. Encourage learners to reflect on their initial selection of the top five hazards, and determine whether their new learning leads them to revise their thinking. 
  2. Ask what caused them to rethink their selection or what helped reaffirm their initial choices.
  3. Provide learners with a copy of the Workplace Hazards Ranking Ladder
  4. Invite learners to use the criteria and evidence to assess and prioritize safety risks, ranking their top five hazards from greatest to fifth greatest urgency.
  5. Using the evidence, criteria, and concern ratings recorded on the worksheet, have learners add brief details or bullet points to support each placement on the ladder so that the level of concern is clear to someone using the ranking to assess and prioritize workplace safety risks.
  6. Invite learners to share their draft ranking ladders and explain the evidence and reasoning for their placement of hazards. Encourage learners to listen for ideas, information, or reasoning from others that might prompt them to reconsider their own ranking.
  7. After considering other viewpoints, have learners revise and finalize their ranking ladders.
  8. Finally, have learners write a brief statement explaining how their completed ranking ladder provides a clear and useful way to assess and prioritize safety risks in a workplace, and why they chose to revise or maintain their original ranking after hearing others’ ideas.

Modify or extend this activity

  • This activity can be extended by deepening learners’ understanding of the science behind each workplace hazard. By understanding the science of the hazard, learners are better able to guard against actions that could put people in harm’s way Understanding science for safer workspaces.

  • The activity can build on this understanding by inviting learners to use their knowledge and understanding to develop innovative ways to inform, educate, or protect others from potential workplace harm Designing for workplace safety.

  • As an additional extension, learners could examine how their hazard-ranking ladder might need to be adapted for different jobs, workplaces, or environments (e.g., construction, healthcare, retail, laboratories); for assessing and prioritizing different types of workplace risks or dangers (e.g., non-electrical hazards, ergonomic risks, environmental or health-related hazards); and to consider how safety risks and protective measures can affect workers differently, including how inclusive design can improve workplace safety for all.

Assessments

In this thought starter activity, opportunities for assessment, in the form of ongoing guidance and feedback, are embedded throughout the instructional practices.

  • Use the initial invitation to select the top five workplace hazards as an opportunity to gather insight into learners’ current thinking, including how they understand the breadth and depth of impact associated with different hazards.
  • Use the Workplace Hazards Worksheet to notice and support learners as they select relevant evidence, connect it to the criteria, and develop reasoned judgments about workplace risks.
  • Use learners’ opportunities to reflect on and revise their initial selections, including discussion with peers, to support and guide flexible thinking and, where applicable, collaborative thinking.
  • Use opportunities for learners to share their reasoning on the Ranking Ladder to support the development of clear communication, including the use of appropriate science-related terms.
  • Use learners’ evolving Ranking Ladder and written explanations to guide feedback on how effectively they are using criteria and evidence to assess and prioritize safety risks.

Teaching Notes

These teaching notes contain more information on the following sections of the activity: 

  • Learning Launch
  • Developing Understanding
  • Reflect and Revise

Learning Launch

If doing this activity with a group of learners, allow time for individual selection of the top five hazards before inviting sharing with the whole group. This supports independent thinking before discussion.

When inviting learners to share, encourage them to explain their thinking about why they selected certain hazards as more urgent and why others were of lesser concern. Emphasize that there is no single correct answer; the goal is to surface initial ideas and reasoning that can be revisited later.

If working with an individual learner, invite them to talk through their initial selections and explain their thinking. Where appropriate, prompt them with questions or additional information to support reflection, without evaluating or correcting their choices.

Support student voice in identifying safety risk. As learners assess and prioritize workplace hazards, emphasize that recognizing risks and being able to name concerns are important parts of workplace safety. Invite learners to consider how workers with different levels of experience or authority might notice hazards differently, and how evidence and criteria can support clear communication about safety risks. Here is the link to WorkSafe BC's Listen to your Gut campaign that empowers young workers to speak up when they think the workplace is unsafe.

Developing Understanding

When presenting the criteria, connect learners’ ideas to the criteria and consider revising or adding to the criteria if warranted. Use questions, examples, or additional information to support learners’ thinking, rather than correcting their ideas.

If doing this activity with a group of learners, allow time for paired or small group discussion as learners read the briefing sheets, record evidence under each criterion, and revisit their initial selection of the top five hazards. Encourage learners to explain their thinking and to listen for similarities and differences in how others are judging urgency. 

If working with an individual learner, encourage them to explain their thinking as they read and consider the details in the briefing sheets, record information under each criterion, and revisit their initial selection of the top five hazards.

Reflect and Revise

If working with a group of learners, use chart paper and markers to have pairs or small groups create a large-format version of the ranking ladder. This helps make learners’ thinking visible.

Invite groups to share their rankings and rationales and encourage others to listen for ideas, information, or reasoning that might prompt them to reconsider their own ranking. Emphasize that revising one’s thinking in light of new perspectives is an expected and valued part of the thinking process.
