The 5 situations that attract a CNESST inspection... and what they really reveal

Thursday, April 23rd, 2026

On a construction site, it sometimes only takes a few minutes to realize whether everything is under control... or whether the risks are piling up.

Inspections don't just happen. They almost always target the same situations: those where the danger is real, immediate, and all too often trivialized. Not because of wilful negligence, but because the pace of the worksite takes over.

And yet, these situations are well known.

FALLS FROM HEIGHT

Falls from height, for example, continue to be one of the main risks. A guardrail temporarily removed, a harness left aside "just for two minutes"... and danger sets in. It's not big decisions that cause accidents, but an accumulation of small compromises.

SCAFFOLDING

The same applies to scaffolding. A structure quickly erected, a check put off until the next day, an improvised adjustment. At the time, everything seems functional. But to an outside eye - that of an inspector - these details become clear signals.

EXCAVATIONS

The excavations tell a similar story. The ground seems stable, the work is progressing, and the pressure to deliver pushes on. Yet, without adequate support, the risk of collapse is very real. Here again, it's not bad intentions, but overconfidence in conditions that can change rapidly.

ELECTRICAL RISKS

Electrical hazards, on the other hand, are more discreet. A temporary connection that becomes permanent, an exposed cable, a poorly identified area. Nothing spectacular, but situations where an error can have serious consequences.

SST COORDINATION

And then there's what ties it all together: coordination.

On construction sites where several teams are involved, health and safety cannot rely on a single person or general goodwill. Without a clear structure and communication, even the best intentions become ineffective. This is often where discrepancies arise - not in the rules, but in their application.

THE ROLE OF PREVENTION

What these situations have in common is not just the risk. It's the fact that they are visible. For an inspector, they quickly reflect the level of site management. But above all, they reveal something deeper: the real importance attached to prevention.

Because beyond the obligations, health and safety remains a rigorous indicator. A well-organized worksite, where risks are identified and managed, is generally more efficient, more stable... and more successful.

The good news is that it's not all about reinventing the wheel.

It's all about getting back to basics: observing, correcting and communicating. Ensuring that best practices are not just known, but applied - every day, in the field.

Because in the end, avoiding an inspection is one thing.
But avoiding an accident is what really counts.
