Does the RSS replace the employer's inspection?

No. The employer still holds LSST section 51 duties. The RSS is a participation mechanism, not a transfer of duty.

Where are the 10 / 20 / 100 worker thresholds?

On the regulation sheet for prevention mechanisms: program, committee, RSS and CoSS. This guide does not republish the articles.

Must every machine be inspected every day by the RSS?

The operator does the daily machine walk-around. The RSS prioritizes zones and open gaps; they do not recapture every item for the operator.

Does OK Sécurité appoint the RSS?

No. Designation follows the LSST. The app records walkthroughs.

Site safety representative: daily inspections

By Claude Piché, founder · Updated September 18, 2026

The site safety representative (RSS) is not a CNESST inspector. Field work is see, record, and close actions — with the crew, not instead of them.

The RSS does not set the thresholds

When an RSS is required, part-time or full-time, and when a site committee or CoSS is added: those are legal thresholds (RMPPCC / LSST). They live on the prevention-mechanisms sheet. This guide does not recompute them.

The question here is practical: once designated, how do you use inspection time without drowning in paper?

Prepare the walkthrough

Map today's tasks, subcontractors, and higher-risk zones (height, excavation, machines, energy). Carry one capture tool: location, date, photos, owner.

A list per machine or situation (excavator, scaffold, height work) avoids rewriting the tour every time.

During: observe, don't only tick

Ask for a demonstration, not only a “yes”: a posted guardrail is weak if it is incomplete. For each gap: one sentence, a hazard, a person, a date.

Vague notes (“be careful”) never close. The RSS ties the finding to whoever can fix it.

After: follow-up and committee

Share a same-day summary. At the site committee, bring still-open findings, not only the latest PDF.

OK Sécurité helps assign lists and export a report. The tool is not a CNESST mandate and does not replace RSS designation.

This article is informational. RSS duties and thresholds (headcount, job cost) come from the LSST and the RMPPCC. OK Sécurité is not certified by the CNESST. Confirm with your prevention program. For information only — this is not legal advice. OK Sécurité is an independent company with no affiliation to the CNESST: we are not mandated, endorsed or certified by it. Where there is any discrepancy, the official text published by Légis Québec or the CNESST prevails.
