How often should we inspect a site?

Frequency depends on risk, site size, and your prevention program. Higher-risk work often needs tighter cadence. Document the rationale for your team.

Who should join an inspection?

Supervision, prevention, and sometimes affected subcontractors participate by topic. The key is that people who can fix a hazard are informed quickly.

Is a photo enough evidence?

Photos help when paired with context: where, what task, what was wrong, and what action is required.

How does this relate to CNESST lists?

Each OK Sécurité checklist groups CNESST-themed checks for a trade or situation. Use them as a walkthrough guide or a completion report.

Construction site safety inspections

Updated March 20, 2026

Solid inspections follow a simple loop: observe, record, and follow up. Use this as a field-friendly structure— it does not replace legal duties or your prevention program.

Why structure inspections

Job sites change daily: access, equipment, materials, and crews shift. Without a shared checklist, teams may skip zones or only address what is obvious.

CNESST-themed checklists help cover critical phases (before, during, after) and keep a trace useful for leadership and workers.

Before the walkthrough

Clarify active and planned work, subcontractors on site, and higher-risk areas (height, energy, traffic, excavation).

Prepare how you will capture notes—paper, tablet, or phone—with location, date, who was present, and photos when helpful.

During the visit

Prefer open questions and demonstrations: a posted procedure is weak if crews cannot show how it is applied.

For each gap, capture the hazard, a realistic due date, and who owns the fix. Vague notes like “be careful” are hard to close out.

After the visit

Share a short summary with affected people and verify corrective actions. History matters for audits and for learning after incidents.

OK Sécurité lets you assign lists, complete on mobile, and export PDF reports for your records.
