A three-column hazard worksheet and a document a worker reads before starting a job are not the same thing, and writing them as though they were is why the second one goes unread.
Key takeaways
The analysis and the instruction are two different jobs, and treating them as the same document is the most common reason a safe work practice ends up unread. The analysis is thorough because it has to be. The instruction has to be usable, which is a different design goal entirely.
CCOHS describes a job safety analysis, sometimes called a job hazard analysis, as "a process which helps assess a job to identify hazards and necessary control measures." The process runs five steps: select the job to be analyzed, break the job down into a sequence of steps, identify the potential hazards at each step, determine the preventive measures needed to control them, and communicate the results. The first four steps produce an analysis. Only the fifth step produces something a worker is meant to read, and CCOHS treats it as a distinct step for a reason — communication is not automatic just because the analysis was thorough.
This is the point most safety manuals get wrong: they hand the analytical document itself to the worker instead of building the communication step CCOHS describes separately. A JSA is typically built as a three-column worksheet — step, hazard, control — and CCOHS says directly that "the table format may not always be the best way to communicate the information," recommending instead that the analysis be converted into a "narrative-style communication format" for the people actually doing the job. A three-column table is excellent for the person building the analysis, because it forces a hazard to be paired with a control at every step. It is a poor format for a worker reading it quickly before starting a task, because a table has no natural reading order and no sense of urgency — every row looks equally important, whether it is "wear gloves" or "this step can sever a finger."
A narrative safe work practice reads like instructions, not like an audit trail. It follows the same sequence CCOHS’s five-step process already established — the job broken into steps — but writes each one as a sentence a worker follows in order, with the hazard and the control folded into that same sentence rather than split across separate columns. “Check the guard is in place and the blade is sharp before you start cutting” carries the hazard and the control in one instruction, in the order a worker actually encounters them, rather than requiring a cross-reference between a hazard column and a control column two rows apart.
Safe work procedures are not a document that exists on its own — CCOHS lists them among the standing elements every health and safety program should include, alongside hazard identification, training, and inspections. That placement matters for how a practice gets built and kept current: it should come out of the same hazard-assessment process that drives the rest of the safety manual, updated on the same trigger — a new process, a changed operation, a significant addition to the work — rather than written once, filed, and left to describe a job that has since changed.
A narrative safe work practice is a standing document, written once from the JSA and revised when the job changes. It is worth naming explicitly what it is not: a field-level hazard assessment, filled out fresh at the start of a shift for that day’s specific site conditions. The two are complementary rather than interchangeable — the standing practice tells a worker how the task is normally done safely, and the daily field check catches whatever is different about today: weather, a change in the surrounding work area, equipment that wasn’t there yesterday. Alberta’s OHS Code frames this as an ongoing statutory duty rather than a specific named form: an employer must assess a work site and identify hazards before work begins, and repeat that assessment when conditions change. A field-level check is industry practice built to operationalize that duty day to day — useful and often expected, but not itself the statutory language, and a company should not confuse having a daily-check form with having done the underlying hazard assessment the Code actually requires.
A well-written practice still needs a delivery mechanism, and that is a separate document again. New workers should encounter it as part of their site orientation, and existing crews should be reminded of it periodically through short, focused toolbox talks — CCOHS is explicit that these informal sessions do not replace formal training, but they are the mechanism that keeps a written practice from being read once at hiring and never again. A practice that only exists in a binder is, functionally, no different from one that was never written.
A JSA for cutting pressure-treated lumber on a chop saw produces a worksheet with steps like “position material,” “make cut,” and “clear offcut,” each paired with hazards (kickback, blade contact, dust exposure) and controls (guard engagement, PPE, dust extraction). Handed to a new crew member as-is, that worksheet is accurate and almost unusable — nothing in it tells the worker what order to actually do things in, or which line matters most.
Converted to a narrative practice, the same analysis reads: check the blade guard is in place and moves freely before you plug in the saw; put on hearing protection, eye protection, and a dust mask rated for treated wood before you start; keep both hands clear of the blade path and use the material clamp rather than holding stock by hand; let the blade stop completely before clearing an offcut. Every hazard from the worksheet is still there — kickback, blade contact, dust — but folded into the sentence describing the step where it applies, in the order a worker actually performs the cut. Nothing was lost in the conversion except the format that made it hard to follow.
No. A job safety analysis is the analytical process — typically a worksheet pairing each step of a job with its hazards and controls. CCOHS recommends converting the results into a separate narrative-style document for communicating the practice to workers, rather than handing over the worksheet itself.
A narrative-style format, written in the sequence the work is actually performed, rather than the three-column analytical worksheet used to build the underlying job safety analysis.
Select the job to be analyzed, break the job down into a sequence of steps, identify potential hazards at each step, determine the preventive measures needed, and communicate the results.
