The Term Everyone Mentions but Few Explain
If you’ve started researching renovation requirements for an older Kamloops property, you may have come across the term HMBI and wondered exactly what it means. HMBI stands for Hazardous Materials Building Inspection — a formal survey process used to identify asbestos and other hazardous materials in a building before renovation, demolition, or other work that could disturb them.
Why HMBI Surveys Exist
WorkSafeBC’s occupational health and safety regulations place responsibility on employers — and by extension, property owners initiating work — to identify hazardous materials before work begins that could disturb them. This isn’t a suggestion; it’s a regulatory requirement tied directly to worker safety, since asbestos exposure remains one of the leading causes of workplace-related deaths in BC.
An HMBI survey is the formal mechanism for meeting that identification requirement. It typically involves a qualified person — someone who has completed WorkSafeBC’s Level S asbestos surveyor and sampler training — conducting a visual inspection, collecting samples of suspect materials, and documenting findings in a written report.
What the Survey Actually Involves
- A walkthrough of the property identifying materials with a reasonable likelihood of containing asbestos based on age and material type
- Targeted sampling of suspect materials — done carefully to avoid releasing fibres during collection
- Laboratory analysis of the collected samples
- A written report documenting what was tested, what was found, and recommendations for any necessary abatement before work proceeds
Who Needs One — and When
If you’re a homeowner planning a renovation on a property built before 1990, or a contractor about to begin demolition or renovation work on an older building, an HMBI survey should generally happen before any disturbance work begins. This applies whether the work is residential or commercial.
It’s worth noting that the certification requirement for performing this type of survey work is not limited to large abatement companies — it applies to anyone conducting asbestos surveys and sampling for the purpose of abatement, including independent operators.
What Happens After the Survey
If the survey confirms asbestos-containing materials are present, the report typically includes recommendations for next steps — which usually means hiring a licensed abatement contractor to safely remove the material before renovation work continues. If no asbestos is found, you have documentation confirming that and can proceed with your project.
Common Misconceptions
- “My contractor will just be careful” — Working carefully around an unidentified hazard is not the same as confirming whether the hazard is present. Caution without testing is still a guess.
- “This only applies to big commercial projects” — The requirement applies to any building work that could disturb hazardous materials, residential included.
- “I’ll just assume it’s there and be careful” — Without testing, you don’t know what type of material you’re dealing with, which affects both the handling procedure and the disposal requirements.
Bottom Line
An HMBI survey is the proper first step before renovating or demolishing any pre-1990 building in Kamloops. It protects you, your contractor, and anyone who will occupy the space after the work is done — and it’s a requirement, not an optional precaution.
