100% tie off in fall protection is required when a worker is exposed to a fall hazard and must remain continuously connected to an approved fall protection system. Across Alberta, British Columbia, Saskatchewan, and other Canadian jurisdictions, fall protection is commonly required at heights of 3 metres or more, and may also be required at lower heights where a fall could cause serious injury. The key issue is not just whether the worker is wearing a harness. The worker must be properly connected, protected while moving, and supported by a fall protection plan that matches the work.
In Alberta, employers and supervisors must ensure a worker is protected from falling if the worker may fall 3 metres or more, less than 3 metres where there is an unusual possibility of injury, into or onto a hazardous substance or object, or through an opening in a work surface. Alberta also requires a fall protection plan where a worker may fall 3 metres or more and is not protected by guardrails. That plan must address fall hazards, the fall protection system, anchors, clearance distances, inspection and use procedures, and it must be reviewed with workers before work begins.
In British Columbia, WorkSafeBC requires fall protection where work is being done at a place from which a fall of 3 metres or more may occur, or where a fall from less than 3 metres involves a greater risk of injury. BC’s regulation also follows a practical control sequence: use guardrails or similar fall restraint where practicable, then fall restraint, then fall arrest or rope access where other options are not practicable. Workers must be instructed before entering an area where a fall risk exists, and workers must use the system provided.
In Saskatchewan, a written fall protection plan is required where a worker may fall 3 metres or more and workers are not protected by a guardrail or similar barrier. The plan must describe the fall hazards and the fall protection system used at the worksite.
A simple rule that says “workers must maintain 100% tie off” is not enough by itself. Workers need to know exactly where to connect, when to connect, what equipment to use, what not to connect to, and what to do when the normal method does not work.
This matters because fall protection failures are often procedural failures, not just equipment failures. The equipment may be sitting in the truck. The harness may be fitted correctly. The worker may even intend to tie off. The real issue is that the procedure does not match the task, the anchor points are unclear, or the work sequence forces workers to improvise.
A good fall protection process starts before the worker reaches the edge. Employers should ask: Can the work be done from the ground? Can guardrails be installed? Can the worker be kept away from the edge using travel restraint? If fall arrest is required, has the employer confirmed anchor strength, compatibility, swing fall risk, free-fall distance, rescue access, and clearance below the worker?
Employers often ask how to write safe work procedures that actually work in the field. The answer is to write the procedure around the task, not around generic wording copied from a manual.
A safe work procedure for 100% tie off should explain the actual job sequence. It should identify when the worker becomes exposed to a fall hazard, what system is used, where the worker connects, how the worker moves while staying connected, and who verifies the setup before work begins.
The procedure should also explain limitations. For example, a worker should know whether the system is for travel restraint or fall arrest. They should know whether the anchor is engineered, temporary, manufacturer-specified, or restricted to a specific piece of equipment. They should understand that tying off to a handrail, pipe, scaffold component, guardrail, or random structural member may not be acceptable unless it has been assessed and approved for that use.
A strong procedure should include pre-use inspection, equipment compatibility, weather and surface conditions, rescue steps, supervisor responsibilities, and stop-work expectations. If the worker cannot stay connected through the whole task, the procedure is not finished.
One of the most common gaps with 100% tie off in fall protection is treating it as a behaviour issue when it is actually a planning issue. Telling workers to “tie off” is easy. Giving them a practical way to stay tied off is harder.
Common problems include unclear anchor locations, poor rescue planning, lanyards that are too long for the available clearance, workers using fall arrest when travel restraint would be better, missing inspection records, incomplete training records, and supervisors not verifying the setup before the job starts.
Another issue is transition points. Workers may be tied off in an aerial lift but disconnect while stepping onto a roof. They may be protected while working on one section of a structure but exposed while moving to the next section. They may connect to one anchor, finish that part of the task, then disconnect before reaching the next anchor. These short transition moments need to be built into the procedure.
When fall protection is vague, workers improvise. When workers improvise at height, the business risk increases quickly. The immediate risk is obvious: serious injury or fatality. The operational effect is also serious. Work stops, supervisors are pulled away from production, equipment may be shut down, emergency response may be required, and the project schedule can be disrupted.
The financial risks can include regulatory penalties, WCB claim costs, increased premiums, replacement labour, retraining, investigation time, rework, legal costs, and lost contracts. In BC construction alone, WorkSafeBC reported more than 5,400 injury claims from falls from elevation from 2020 to 2024, including almost 1,900 serious injuries and 35 fatalities. WorkSafeBC also issued 152 administrative penalties for inadequate fall protection in 2024, totalling $1,069,720.
The compliance risk is just as important. Poor fall protection documentation can affect COR audits, client prequalification, contractor management, and regulatory due diligence. If a fall protection plan does not match the work, if workers have not reviewed it, or if training records and inspections are missing, the employer may have difficulty proving that the system was understood, implemented, and monitored.
Measurable performance should focus on leading indicators the employer can verify. Examples include 100% fall protection training completion for exposed workers, documented pre-use equipment inspections before work at height, 95% or higher completion of supervisor field observations, correction of high-risk fall protection deficiencies within 24 to 48 hours, and closure of non-urgent corrective actions within 30 days. These are defensible because they can be tracked through training records, inspection forms, site observations, corrective action logs, and audit files.
Situation: A mid-sized contractor working across Alberta and Saskatchewan had a generic fall protection procedure that told workers to maintain 100% tie off, but it did not identify task-specific anchor points or transition methods.
Action: The employer updated the fall protection plan, created task-specific safe work procedures, identified approved anchors, added a supervisor verification checklist, refreshed worker training, and completed a rescue drill.
Result: Within two months, the company had complete training records for exposed workers, documented weekly inspections, and reduced repeat fall protection deficiencies from eight observations in the first month to one in the second month. The company also had clearer documentation available for client review and audit preparation.
Calgary Safety Consultants helps employers turn fall protection requirements into practical field systems that supervisors and workers can actually use. This includes reviewing existing safety manuals, developing or improving fall protection procedures, supporting hazard assessments, preparing safe work practices, and helping employers understand documentation expectations for Alberta, British Columbia, and Saskatchewan worksites.
We can also support COR and SECOR preparation, audit readiness, corrective action tracking, training records, inspections, and compliance support. For employers that work at height, the goal is not to create paperwork for the sake of paperwork. The goal is to build a safety system that shows what workers are expected to do, how supervisors verify it, and how the employer can prove due diligence when it matters. Calgary Safety Consultants provides these services across Alberta, BC, and Saskatchewan.

100% tie off in fall protection should never be treated as a slogan. It has to be planned into the job before workers reach the fall hazard. When employers confirm the hazards, equipment, anchor points, procedures, training, supervision, and rescue process, they create a system workers can actually use in the field.

Fall protection requirements vary by province, but Alberta, British Columbia, and Saskatchewan all require employers to protect workers from fall hazards at defined heights and in situations where a fall could cause injury. In practical terms, employers should assess the task, apply the required provincial rules, and ensure workers remain protected throughout the work. The blog’s internal links should connect readers to your broader safety consulting and compliance pages for employers working across these provinces. Your current site has relevant pages for consulting, COR support, safety manuals, training, and hazard assessment support. (Calgary Safety Consultants)
No. Wearing a harness does not mean the worker is tied off. The harness must be connected to a suitable fall protection system, such as an approved anchor, lanyard, lifeline, self-retracting lifeline, or travel restraint system.
Workers may need equipment such as double-leg lanyards, horizontal lifelines, self-retracting lifelines, engineered anchor points, or other approved systems that allow continuous connection. The work method should be planned before the task begins so workers are not forced to disconnect and improvise while exposed to a fall hazard.
When considering how to write safe work procedures, start with the actual task rather than generic policy wording. The procedure should explain where the fall hazard begins, what equipment is required, where workers connect, how they move while staying protected, how equipment is inspected, and what rescue steps apply if a fall occurs.
Travel restraint is designed to prevent the worker from reaching the fall hazard in the first place. Fall arrest is designed to stop a worker after a fall has started, which means clearance distance, anchor strength, equipment compatibility, and rescue planning become critical.
Documented procedures help prove that the employer identified the hazard, selected controls, trained workers, and gave supervisors a clear method to verify the work. This supports compliance, COR readiness, client prequalification, audit performance, and due diligence if an incident or inspection occurs.
100% tie off in fall protection means a worker remains continuously connected to an approved fall protection system whenever they are exposed to a fall hazard. The worker should not disconnect while moving, repositioning, transferring between work areas, or accessing an elevated location unless another effective control is already in place.
