The Exposure

Western Red Cedar Is the Reason

Cedar dust contains plicatic acid, and western red cedar asthma is one of BC's best-documented occupational lung diseases. Symptoms often last long after exposure ends. Crews also breathe softwood dust, diesel and summer wildfire smoke.

BC's OHS Regulation doesn't require spirometry. But without a baseline, any later decline is presumed to be yours.

We've tested 45 workers at Sigurdson Forest Products in Chilliwack in a single visit.

What's Included

Built for Mill Scheduling

Ignore shifts and you get 40% participation.

How It Runs

  1. Before: send the crew list and a spot near the lunchroom.
  2. On site: 10-15 minutes per person.
  3. Shift coverage: we stay through shift change.
  4. After: physician review and a report flagging changes.

40-70 tests per day, alongside hearing testing for forestry and wood products.

Wood Dust and Diesel Exposure

For cedar, softwood dust and equipment exhaust.

Physician-Reviewed Results

Every test reviewed by a licensed physician.

Shift Coverage

Afternoon and night crews included.

Why Partner With Us

Why BC Mills Test With Us

We already test hearing in mills across the Fraser Valley, Interior and Island.

One Visit, Two Programs

Mills need hearing tests anyway. Add spirometry: one disruption, one invoice.

Honest About What Is Required

Hearing testing is mandated and we're authorized (IAB #436). Spirometry isn't, and we won't sell it as compliance. Most mills still choose a baseline.

Frequently Asked Questions

Common questions about spirometry in BC sawmills, planer mills and forestry operations.

Is spirometry required for sawmill workers in BC?
arrow_forward_ios

No. There is no section of the BC OHS Regulation that requires spirometry for wood dust or any other exposure. Where you have an exposure control plan, OHSR 5.54(2)(f) lists health monitoring as an element when required, and spirometry is how most employers meet that. Otherwise it is a voluntary program.

Why is western red cedar treated differently from other wood dust?
arrow_forward_ios

Cedar dust contains plicatic acid, which is a recognized respiratory sensitizer. Occupational asthma from red cedar exposure is well documented in British Columbia, and unlike an irritant reaction it can persist after exposure ends. Crews working cedar are the highest priority group in most mills.

How do you handle shift work?
arrow_forward_ios

We stay through shift change so afternoon and night crews are tested rather than skipped. For larger operations we schedule across two days or add technicians. Tell us your shift pattern when you book and we will build the day around it.

Can you test bush crews as well as mill staff?
arrow_forward_ios

Yes, subject to access. Mill sites and yards are straightforward. For remote crews we need a place to set up with reasonable access - talk to us about the specific site and we will tell you honestly whether it works.

Can this run with our hearing tests?
arrow_forward_ios

Yes, and that is how most mills do it. Your crew comes through once for both. See hearing testing for forestry and wood products for how that program runs.

Add Spirometry to Your Next Mill Visit

For crews in cedar, softwood dust and diesel. Easiest alongside hearing tests.
