Compare control options by changing exposure
See this course’s project requirements
A fictional job-step/hazard/control table for a low-risk office supply task, with control-priority reasoning, a supervisor review request and a changed-condition stop decision.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Save task-scope card with paper-only authority boundary; include the original-case decision evidence and a separate changed-case result.
- Save three-step analysis with condition links and questions; include the original-case decision evidence and a separate changed-case result.
- Save two specific scenarios and no-blame wording; include the original-case decision evidence and a separate changed-case result.
- Save control comparison with limits and implementation owner; include the original-case decision evidence and a separate changed-case result.
- Save residual questions and verification queue; include the original-case decision evidence and a separate changed-case result.
- Save versioned paper JHA packet with two exact next checks; include the original-case decision evidence and a separate changed-case result.
Review and revise
Use these criteria to check your work and choose what to improve.
- The final packet uses the supplied task-specific constraints and all six records agree.
- Every result can be traced to an identifier, input, calculation or stated decision rule.
- Changed-case practice updates dependent records and keeps holds or uncertainty visible.
- The packet states the learner role, authority boundary and specific next verification needed before real work.

The idea in everyday life
Original fictional workplace practice; paper or a local document is sufficient. The rules and records below are supplied for this exercise, not asserted universal workplace policy. Hemlock paper options for cable:remove obsolete cable from route by responsible staff; reroute controlled cable off walkway under qualified review; sign“be careful”without changing route. For high tray:review lower accessible location; no learner climbing/physical trial.
Controls aim to remove or reduce exposure; a reminder alone does not remove the physical condition. Any implementation requires responsible authorized review.
Compare control options by changing exposure — worked practice
Controls aim to remove or reduce exposure; a reminder alone does not remove the physical condition. Any implementation requires responsible authorized review.
Hemlock paper options for cable:remove obsolete cable from route by responsible staff; reroute controlled cable off walkway under qualified review; sign“be careful”without changing route. For high tray:review lower accessible location; no learner climbing/physical trial. Use paper or a local document. Preserve the original case and make a separate changed-case record.
1. Step 1
Match options to the condition they change.
You should see: Removal eliminates cross-route cable; reroute changes exposure; sign leaves condition.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
2. Step 2
Prefer review of source/environment changes over only reminders.
You should see: Removal/reroute addresses physical route condition.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
3. Step 3
Check new conditions and responsible approval.
You should see: No improvised cable repair; qualified/site lead review.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
4. Step 4
Save control comparison with limits and implementation owner.
You should see: Paper recommendations for route and tray, not certified safe methods.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
What to finish
Save control comparison with limits and implementation owner; include the original-case decision evidence and a separate changed-case result.
Watch for this
Calling a warning a removed hazard or implementing a physical change without authorization.
How can I tell I understand it?
Using the supplied identifiers, I can save control comparison with limits and implementation owner. My changed-case record names the revised condition and explains which dependent decision it changes.
