Lead Testing
Lead Testing
What It Is
Lead testing determines the presence of lead-based paint or coatings in a building. Lead was widely used for durability and pigmentation until it was slowly phased out in residential paints.
Why It’s Important
During sanding, cutting, or demolition, lead dust can spread easily and cause serious health effects, particularly neurological damage, anemia, and developmental issues in children.
WorkSafeBC requires identification and control of lead-containing materials before any work that could disturb them begins.
What’s Involved
- Visual Assessment – Identify areas likely to contain lead-based paint or coatings.
- Sampling – Paint chips or dust wipes are collected and analyzed by an accredited lab (using Atomic Absorption Spectroscopy or XRF).
- Report – The report details lead concentrations and recommendations for safe removal, encapsulation, or containment.
Common Lead Sources
- Paint on wood trim, windows, and doors
- Painted masonry and metal surfaces
- Old plumbing fixtures and solder
- Glazed tiles and coatings
