Understanding Hazardous Substances in Alberta Workplaces
Hazardous substances show up in Alberta workplaces more often than most people realize — sometimes in plain sight, sometimes hidden behind walls or under floors. Whether you’re running a construction crew, managing an industrial facility, or overseeing a commercial building, you’re responsible for knowing what your workers could be exposed to and taking steps to protect them.
These hazards come in a lot of different forms. Older buildings often contain asbestos tucked into insulation, drywall, or flooring materials. Lead turns up in paint, pipes, and certain industrial processes. Out in the oil and gas sector, workers may encounter BTEX chemicals, naturally occurring radioactive materials (NORMs), or hydrogen sulfide gas on a regular basis. Each of these carries its own health risks, and without a solid management plan, any of them can become a serious problem.
The hardest part for most employers isn’t dealing with hazardous materials once they’ve been found — it’s knowing where to look in the first place. A lot of these substances aren’t obvious until something disturbs them: a renovation, routine maintenance, or even just day-to-day work. That’s why identifying risks early, before exposure happens, needs to be a core part of any workplace health and safety plan.
How to Identify and Assess Workplace Risks
Managing hazardous substances starts with a thorough risk assessment. That means walking through the workplace, understanding what materials are present, and pinpointing where workers might realistically encounter something harmful. An older building might need an asbestos management plan. An industrial site might need regular air quality checks for chemical vapours or gas leaks.
Testing is where you get real answers. Asbestos testing confirms whether building materials contain hazardous fibres before anyone cuts into them. Lead testing tells you whether surfaces or settled dust are putting workers at risk, especially during renovations. Air quality testing can pick up airborne contaminants like BTEX compounds or hydrogen sulfide that you’d never know were there otherwise. In some industries, monitoring for NORMs exposure is also part of the picture to keep radiation levels in a safe range.
Once you know what you’re dealing with, the next step is figuring out how serious the risk is. Not every hazardous substance needs to come out immediately, but all of them need to be managed properly. That might mean restricting access to certain areas, improving ventilation, or putting specific safe work procedures in place. The goal is to keep exposure as low as possible and make sure no one is working in conditions that put their health at risk.
Good documentation matters here too. Alberta’s occupational health and safety requirements expect employers to keep records of hazard assessments, test results, and whatever control measures are in place. Beyond compliance, that documentation gives you a clear, reliable reference point whenever future work is planned for the site.

Identifying a hazard is only half the job. Once you know what’s there, you need a real plan to deal with it. For materials like asbestos and lead, that usually means professional removal or encapsulation by certified technicians, with proper containment in place to make sure nothing spreads during the work.
In industrial settings, the focus often shifts more toward monitoring and ongoing control. Gas detection systems for hydrogen sulfide, ventilation upgrades to reduce airborne contaminants, regular NORMs testing — the right approach depends entirely on what your site is dealing with. There’s no one-size-fits-all solution, and mitigation plans should reflect the actual conditions workers are facing.
Training is just as important as any physical control measure. Workers need to know what hazards exist on site, how to follow safe work procedures, and how to use their personal protective equipment properly. Making Safety Data Sheets accessible and keeping the team informed helps prevent exposure and builds a culture where safety isn’t an afterthought.
We work with employers across Central Alberta on all of this — testing, assessment, and remediation for hazardous substances in all kinds of workplaces.
Asbestos management in an aging building, lead testing ahead of a renovation, air quality monitoring on an industrial site — whatever the situation, we help businesses get ahead of the risk instead of reacting to it.
Keeping a workplace safe isn’t a one-time project. It takes regular inspections, updated assessments, and continued monitoring as conditions evolve over time.
Addressing problems early and working with professionals who know what they’re doing protects your workers, keeps you on the right side of regulations, and lets your operations keep moving.
