Falls, unguarded openings, and unstable scaffolding are not general workplace hazards, they are construction-specific ones. Here are the ten violations Western Canadian job sites see most often, and what a COR-ready crew does differently.
A warehouse and an active construction site do not share the same risk profile. General workplace hazards like missing PPE or poor ergonomics show up everywhere, but a construction site adds height, open excavations, heavy mobile equipment, and site conditions that change week to week as the build progresses. That combination produces a specific, repeatable set of violations, and this list stays inside that reality rather than repeating the broader cross-industry hazards we cover elsewhere on this site.
These ten issues turn up again and again during COR and SECOR field audits and site inspections across Alberta, BC, Saskatchewan, and Manitoba. Almost none of them require expensive equipment to fix. Most come down to a written procedure, a competent person assigned to check it before work starts, and a crew that has actually been walked through the plan rather than handed a binder on day one.
Falls and Unprotected Edges
Fall protection is the violation that shows up most consistently on construction sites, and it usually is not a missing harness. It is a harness and lanyard that were never inspected before the shift, an anchor point that was never engineered or rated for the load, or a fall protection plan that does not exist in writing for work being done above the provincial threshold height. Guardrails removed to move material and never put back are just as common, and just as serious.
- Lanyards, harnesses, and self-retracting lifelines not inspected before use or still in service after a fall event
- Anchor points chosen by the crew rather than specified by a qualified person
- Guardrails taken down for material handling and not reinstalled before the next shift
- No written fall protection plan for roof work, leading edges, or floor openings above the threshold
Unguarded openings are the other half of this hazard. Floor and wall openings left uncovered during framing, skylights that are not rated to be walked on and not covered, and stairwell openings without temporary guardrails are all common on multi-storey builds. A cover that has been kicked aside or a barricade that was never replaced after material delivery counts as an unguarded opening even if it was compliant an hour earlier.
Scaffolding and Access Equipment
Scaffolding violations usually trace back to who erected it. A scaffold that was moved or extended by whoever was closest, without a competent person signing off and tagging it, is an uncertified scaffold even if it looks solid. Missing base plates or mudsills on uneven ground, incomplete guardrails on upper platforms, and platforms loaded well past their rated capacity are the specific gaps inspectors flag most often.
Ladders cause a smaller number of serious injuries but a much larger number of near misses. The pattern is consistent: the wrong ladder type for the job, an extension ladder set at the wrong angle or not tied off at the top, a stepladder used as a work platform instead of a ladder, and damaged ladders that stay in rotation because nobody tagged them out.
Site Conditions and Struck-By Hazards
Housekeeping does not sound like a safety category, but on a construction site it is a direct line to struck-by and trip injuries. Material staged in a walkway or inside a mobile equipment swing radius, debris not cleared at the end of the shift, hoses and extension cords crossing active paths, and poor lighting in stairwells or lower levels are the conditions that turn a routine task into an incident.
The related hazard is traffic control between workers on foot and mobile equipment on site. A backing vehicle without an assigned signaller, blind spots that were never mapped, no physical barrier separating pedestrian routes from equipment lanes, and no traffic control plan for site access all show up repeatedly, especially during the busiest phase of a build when equipment density is highest.
Excavation and Confined Spaces
Trenching and excavation work carries some of the highest-consequence risk on a construction site. The recurring gaps are trenches beyond the provincial depth threshold with no shoring, sloping, or shielding in place, spoil piles stacked too close to the edge, no ladder or ramp within safe walking distance for egress, and no daily inspection by a competent person before workers re-enter after rain or a freeze-thaw cycle.
Confined space entry is less frequent on a typical build but far less forgiving when it is missed. Manholes, tanks, and utility vaults entered without atmospheric testing, no written entry permit, no attendant stationed outside, and no rescue plan in place before entry are the specific failures that recur on civil and utility-heavy construction projects.
A single unrated lanyard or one missing guardrail is enough to fail a COR audit observation outright. Auditors do not average a fall hazard against the rest of a well-run site, and neither should your own inspections.
Equipment and Energy Control
Crane and rigging violations tend to cluster around qualifications rather than the equipment itself: a signaller or rigger who has not been formally trained for the role, loads that exceed rated capacity, damaged slings or chains still in service, and no established exclusion zone under a suspended load. These are also the violations most likely to draw a stop-work order on the spot.
Lockout and tagout gaps on construction sites usually involve mobile equipment rather than fixed machinery, which is where crews get complacent. Servicing equipment without isolating hydraulic, electrical, or stored energy, no site-specific lockout procedure for the equipment actually in use, and workers who have not been trained on that specific machine's isolation points are the pattern that keeps repeating.
Building This Into Your COR Audit Prep
In an Alberta COR audit administered through ACSA, several of these violations get caught on the area inspection questions, things like housekeeping, scaffolding, and excavation conditions, while equipment-specific gaps like crane certification and lockout procedures land on the separate equipment inspection questions. Knowing which bucket a hazard falls into matters when you are building or reviewing your inspection checklists, because a strong area inspection program will not automatically catch an equipment-side gap and vice versa.
The fix for all ten of these starts the same way: written procedures that match the actual work being done, a fall protection plan and site-specific lockout procedure that name real anchor points and real isolation steps rather than generic language, and field inspections that happen often enough to catch a guardrail that came down yesterday. If your safety manual has not been updated to reflect current site conditions, or your last COR audit surfaced findings you have not closed out yet, that is the place to start.
On-Track Safety Solutions builds site-specific safety manuals, runs COR and SECOR audits, and provides field safety support across Alberta, BC, Saskatchewan, and Manitoba. If you want a second set of eyes on your fall protection plan, your scaffolding inspection process, or your excavation procedures before an auditor or an incident finds the gap, reach out and we can walk through what your site actually needs.
