WHMIS 2015 Signage Requirements: What Every Facility in Western Canada Needs to Know

If you've ever stood in a storage room trying to figure out whether your hazard labels are actually WHMIS 2015 compliant, you're not alone. Ten years after the switch from WHMIS 1988 to the GHS-aligned WHMIS 2015 system, it's still one of the most common questions we field — and one of the easiest things for a facility to get wrong without realizing it.

Here's what WHMIS 2015 actually requires, and where the gaps usually show up.

What Changed With WHMIS 2015

WHMIS 2015 aligned Canada's hazard communication system with the Globally Harmonized System (GHS), which most of Canada's trading partners already used. For facilities, the practical difference is in the labels themselves. A compliant WHMIS 2015 label needs:

• A pictogram — the red-bordered diamond symbols for flame, corrosion, health hazard, and so on

• A signal word — "Danger" or "Warning," depending on severity

• Hazard statements — standardized language describing the specific hazard

• Precautionary statements — what to do about it

• Supplier identification — who's responsible for the product

The old WHMIS 1988 system used different symbols entirely (the circular hazard class symbols many of us grew up with), and a facility still running those isn't compliant, even if the sign is in good physical condition.

Where WHMIS Signage Actually Needs to Show Up

Compliance isn't just about the label on the container. A properly built WHMIS system covers:

Controlled product storage areas — clear signage identifying what's stored and its hazard class, visible before someone opens the door.

Workstations and process areas — anywhere a controlled product is decanted, mixed, or used outside its original container needs a workplace label, which has slightly different requirements than a supplier label.

Transport and transfer points — loading docks, tanker fill points, and anywhere product moves between containers.

Emergency information — signage that tells someone where the Safety Data Sheets are, and who to call if something goes wrong.

If your facility has controlled products in more than one building, or across multiple sites, the bigger challenge usually isn't any single sign — it's making sure the same product is labelled the same way everywhere. Inconsistent labelling between sites is one of the most common findings we see when a company brings us in to audit an existing system.

The Mistakes We See Most Often

Mixed WHMIS 1988 and 2015 signage on the same site. This happens gradually — old stock gets used up slowly, new labels go up as needed, and eventually you've got both systems running side by side without anyone deciding that on purpose.

Faded or damaged decals that are technically still "there." A WHMIS decal that's sun-bleached to the point of being unreadable doesn't meet the intent of the requirement, even if it's technically still stuck to the wall. Materials matter here — outdoor and high-traffic industrial environments break down standard decals faster than most people expect.

No workplace labelling for decanted or transferred product. Original containers usually come pre-labelled from the supplier. What gets missed is the secondary container — the pail, the drum, the day tank — that also needs a workplace label once product goes into it.

Treating WHMIS as a one-time purchase instead of a system. Facilities grow, products change, and regulations get updated. A WHMIS program that isn't reviewed periodically drifts out of compliance, one small gap at a time.

How We Approach WHMIS Signage

We've been building WHMIS-compliant signage and decals since the system existed, first for oil and gas clients and now across industrial, manufacturing, warehousing, and construction operations throughout Western Canada. The thing that changes fastest for our clients isn't usually the regulation — it's the site. New product lines, new locations, new hazards. We build WHMIS systems the same way we build everything else: consistent formatting, durable materials chosen for where the sign actually lives, and a process that makes it easy to update one location without leaving the others behind.

Common Questions

Q: Is our facility required to update from WHMIS 1988 to WHMIS 2015?

A: Yes — WHMIS 2015 has been the required standard for several years now. If your facility still has WHMIS 1988-style circular symbols in active use, that signage needs to be replaced.

Q: Do workplace labels need the same information as supplier labels?

A: No, workplace labels have a shorter required format — but they still need to clearly identify the product, its hazards, and reference the SDS. We can walk you through exactly what's needed for your specific application.

Q: Can IDENT audit our existing WHMIS signage for gaps?

A: Yes. This is common work for us, especially for facilities managing signage across more than one location. Give us a call and we'll help you figure out what's current, what's outdated, and what's missing.
