About the certification

WorkSafeBC Asbestos Abatement Certification, Level 1

Since January 1, 2024, anyone performing asbestos abatement work in British Columbia must complete training from a WorkSafeBC-approved provider and hold a WorkSafeBC certificate, and abatement contractors must be licensed. Level 1 is the foundational-awareness certificate for people who transport asbestos material or dispose of asbestos waste. It has no prerequisite and is valid for three years.

To be certified, you complete an approved training program and pass a written exam. WorkSafeBC does not publish the exam's question count, pass mark or time limit. Training providers describe an exam of roughly an hour with an 80% pass mark, but this is not confirmed by WorkSafeBC, so ExamHub's practice test uses 40 questions, 80% and 60 minutes only as an estimate.

ExamHub's free practice quiz has 80 original questions built from the Level 1 core competencies, Part 6 of the OHS Regulation and B.C. waste asbestos guidance.

Sample asbestos Level 1 practice questions

Five sample questions from the question bank, with the answer and explanation.

Question 1
Under OHS Regulation Part 6, a manufactured article or material is generally asbestos-containing material (ACM) when it tests at what level?
  • 0.5% or more asbestos, using the specified test methods
  • 1% or more asbestos, using a standard laboratory method
  • 5% or more asbestos, using the specified test methods
  • A trace amount of asbestos spotted during a visual field check

Why: Section 6.1 defines ACM as a manufactured article or material that tests at 0.5% or more asbestos using the specified NIOSH or US EPA methods. Vermiculite insulation is treated separately.

Question 2
What clearance air sampling result is required before a containment is dismantled, under s. 6.12?
  • 0.02 f/ml or less in the previously contaminated areas
  • 0.2 f/ml or less in the previously contaminated areas
  • 2.0 f/ml or less in the previously contaminated areas
  • 0.002 f/ml or less in the previously contaminated areas

Why: Before dismantling a containment, clearance sampling must show 0.02 f/ml or less in the areas that were contaminated.

Question 3
How long must records of asbestos risk assessments, inspections, air monitoring, training and incidents be kept under s. 6.32?
  • At least 10 years
  • At least 1 year
  • At least 2 years
  • At least 5 years

Why: Section 6.32 requires risk assessments, inspections, air monitoring results, training records and incident reports to be kept for at least 10 years.

Question 4
Under the B.C. Hazardous Waste Regulation, when is waste asbestos hazardous waste?
  • When it is over 1% asbestos by weight and powdery, friable or unbound
  • When visible fibres can be seen on the surface of the material
  • When it is non-friable and remains tightly bound in a solid matrix
  • When it weighs more than 5 kg, in whatever form it takes

Why: Waste asbestos is hazardous waste at more than 1% asbestos by weight if it is powder or dust, friable, or its fibres are no longer bound in a matrix.

Question 5
How much cover material must be placed on waste asbestos buried in an authorized landfill?
  • 0.5 m
  • 0.05 m
  • 5 m
  • 0.15 m

Why: Waste asbestos disposed at an authorized landfill must be buried with 0.5 m of cover material.
