Industrial Hygienist in Spokane: What You Actually Need

Start with the direct answer, because most people searching this term are not sure what they are looking for. We are not Certified Industrial Hygienists. Nobody at this company holds the CIH credential, and we will not imply otherwise. What we do is building science and microbial assessment: moisture diagnosis, mold and indoor air quality sampling, laboratory analysis through accredited labs, and defensible written reporting. For a large share of the projects that come to us asking for an industrial hygienist, that is exactly the service the project actually needs. For the rest, it is not, and we will tell you so and point you toward someone who holds the credential.

That distinction is worth a full page because as far as we can tell nobody else in Spokane or Coeur d'Alene explains it, and several firms in this market use the phrase loosely enough to leave the wrong impression.

What an industrial hygienist actually is

Industrial hygiene is the discipline of anticipating, recognizing, evaluating and controlling workplace hazards that can affect health. The scope is broad and mostly occupational: chemical exposure, airborne contaminants, noise, heat stress, ergonomics, ventilation adequacy, respiratory protection programs, radiation, and the sampling strategies and statistics used to determine whether a worker's exposure exceeds an occupational limit.

CIH is a protected credential. Certified Industrial Hygienist is awarded and administered by the American Board of Industrial Hygiene. It requires a qualifying bachelor's degree with specific coursework in the sciences, several years of documented professional industrial hygiene practice, and passage of a comprehensive examination, plus ongoing certification maintenance. It is not a class you take on a weekend. Only ABIH can confer it, and the term is enforced. Anyone using it who has not earned it is misrepresenting a credential.

There are adjacent credentials that are also real and also distinct: CSP for safety professionals, CAIH, and CIEC or CMC certifications in indoor environmental consulting, which are industry certifications rather than the ABIH credential. They are not interchangeable, and when a specification calls for one specifically, a different one does not satisfy it.

When your project genuinely requires a CIH

Hire a CIH, or a firm that employs one, when any of the following is true.

A contract, specification or insurance requirement names the credential. If the RFP, the remediation protocol requirement, the lender, or the carrier says CIH, that is the end of the analysis. No substitute satisfies a named credential requirement, and no amount of relevant experience does either.

The question is occupational exposure against a regulatory limit. Personal breathing zone sampling for a worker against an OSHA permissible exposure limit or an ACGIH threshold limit value is industrial hygiene work in the formal sense. That includes silica, lead, solvents, welding fume, isocyanates, hydrogen sulfide, and similar. Exposure assessment against a legal limit requires the sampling strategy, statistics and professional judgment that certification exists to demonstrate.

Litigation where the credential itself will be examined. In contested matters, opposing counsel will attack qualifications before they attack findings. If a case is likely to turn on the credentials of whoever performed the assessment, retain someone whose credentials answer that question cleanly.

Complex chemical exposure or a mixed hazard assessment. Multi-contaminant industrial settings, process emissions, confined space atmospheres, respiratory protection program design, or a facility-wide exposure assessment program.

A remediation protocol is required to be authored by a CIH. Some institutional owners and some carriers require this by policy. Again, the requirement decides it.

If your situation is on that list, say so when you call and we will save you the appointment.

What we provide

We do building science and microbial assessment. Specifically:

Moisture and building envelope diagnosis. Pin and pinless moisture meters, thermal imaging for temperature differentials behind intact finishes, borescope inspection of wall cavities, chases and plenums, and psychrometric readings for temperature, relative humidity and dew point by zone. The purpose is to find where water is entering or condensing and to define the extent of affected material with instrument readings rather than opinion.

Mold and fungal sampling. Air sampling with a calibrated pump drawing a measured volume through a spore trap cassette, Air-O-Cell or Allergenco-D, analyzed by an accredited laboratory using direct microscopic examination. Surface sampling by swab or tape lift to confirm whether visible growth is fungal. Bulk sampling of materials. Every job includes an outdoor control sample, because indoor spore counts have no meaning without a same-day outdoor baseline from the same property.

Post-remediation verification. Visual assessment of the work area and containment, moisture verification, and air sampling inside containment against an outdoor control, evaluated against IICRC S520, the industry standard for professional mold remediation.

Other indoor environmental testing. Radon, which matters here because both Spokane County and Kootenai County are EPA Radon Zone 1, the highest tier, with predicted average indoor levels above the 4 pCi/L action level. VOC screening. Asbestos and lead sampling for materials in question. Methamphetamine residue surface testing.

Reporting built to be reviewed by someone who was not there. Chain of custody, measured volumes, raw laboratory data attached, photographs keyed to locations, and explicit statements of method and limitation.

What we do not do: personal breathing zone exposure sampling against OSHA limits, occupational exposure assessment programs, respiratory protection program design, or anything requiring the ABIH credential. We also do not perform remediation, ever, and we take no referral fee from remediation contractors.

Which one does your project need

Why buildings in this market generate these calls

The failure modes here are moisture events, not humid climate. Spokane averages 17.2 inches of rain and 43.9 inches of snow a year. Coeur d'Alene averages 26.6 inches of rain and 42.4 inches of snow, meaningfully wetter on the Idaho side. Neither reads as a mold climate on paper. The problems come from discrete events: hard freezes and burst pipes, ice dams pushing meltwater into roof and wall assemblies, spring melt into below-grade space, failed roof drains and parapet flashing on flat commercial roofs, and mechanical failures like a plugged condensate drain or a saturated coil pan, which are climate-independent and happen year round.

In the City of Spokane roughly 27% of housing was built before 1950, and the commercial core carries a lot of early twentieth century masonry with limited cavity ventilation and original or heavily modified mechanical systems. Water damage and freezing claims occur at about 1.61 per 100 insured properties per year nationally. That is roughly one in sixty properties filing a water claim annually, and the American Housing Survey suggests actual leak-related water damage runs five to six times the claim rate because most of it is never claimed.

None of that requires a CIH. It requires someone who can find water, define its extent, sample correctly and write it down defensibly.

Neither state licenses this work

Washington does not license mold inspection, assessment or remediation. The Department of Health provides guidance and states plainly that there are no certification requirements and that anyone can call themselves a mold specialist without training or credentials. Idaho licenses neither mold work nor home inspection.

That is the regulatory context, and it cuts two ways. It means credentials in this field are voluntary, so a title on a website is not verification of anything. It also means the way to evaluate a firm is method, independence and the report itself. Ask what the sampling plan is and why. Ask whether an outdoor control is included. Ask whether the same company will bid the repair. Ask to see a redacted sample report.

New York went further and made it illegal under Labor Law Article 32 for one company to both assess and remediate the same property. Washington and Idaho have no such rule, which is why we state ours: we test only, and we take nothing from the contractors who fix what we find.

Questions we get on this

Can you write a remediation protocol? We document conditions, extent of affected material and moisture state, and we verify completion against IICRC S520. If your project requires a formal remediation protocol authored by a CIH, that is a CIH engagement and we will say so.

Will you refer us to a CIH? Yes, at no charge and with no referral fee to us, the same way we handle every other referral. Tell us what the requirement is and we will point you at someone who meets it.

Do you have any certifications at all? Credentials in this field are voluntary in both states. We would rather you evaluate us on the method, the independence and the report than on an acronym, and we will show you all three before you book.

Is a CIH better for a routine mold complaint in an office? Not necessarily, and it is usually more expensive. A CIH is the right call when the credential is required or when the question is occupational exposure. For a moisture-driven microbial complaint, what matters is whether the assessment finds the water and documents it correctly.

We were told we need an "industrial hygienist report" by our insurer. Now what? Send us the exact requirement language. If it names a credential we cannot meet, we will tell you within the hour and refer it out. If it describes an assessment and a report, which is more common, we can usually do it.

Talk to us before you book anyone

Describe the building, the problem and any requirement language you were given. We will tell you honestly whether this is our work or someone else's. That call costs nothing and it has saved several clients from paying for the wrong service.
