Sample Submission & Chain of Custody Instructions
(For Asbestos, Lead, and Mold Analysis)
To ensure accurate laboratory processing and compliance with regulatory standards, please complete the Chain of Custody (COC) form in full and follow the collection and handling guidelines below.
Incomplete or improperly completed submissions may delay processing.
Please provide:
- Client / Homeowner Name
- Address or Project Location
- Contact Phone and Email
- Date and Time Samples Collected
- Sampler's Name / Initials
For each sample, list:
- Sample ID / Label (must match the container label)
- Sample Type (e.g., drywall, insulation, paint chip, dust wipe, tape lift, air cassette)
- Location / Area of Collection (e.g., kitchen ceiling, window sill, basement wall)
- Date and Time of Collection
-
Requested Analysis
- Asbestos: PLM (Polarized Light Microscopy) or TEM (Transmission Electron Microscopy)
- Lead: Paint Chip, Dust Wipe, or Soil Analysis by AAS/ICP
- Mold: Direct Microscopic Examination or Culture
(For Homeowners and Non-Professionals)
If you are collecting samples yourself, proceed with extreme caution. Improper collection may cause personal exposure or compromise sample integrity.
A fit-tested half-face respirator equipped with P100 filters, Disposable nitrile gloves, and Disposable coveralls to prevent contamination and exposure.
- Lightly mist the area with water to minimize fiber release.
- Using hand tools only (no power tools), carefully remove 1–2 teaspoons of representative material.
- Place material in a clean, sealable plastic bag, double-bag it, and label clearly with sample ID and location.
- Avoid disturbing large areas of suspected asbestos-containing materials (ACMs).
- Wear gloves and respirator at all times to avoid ingestion or inhalation of dust.
- For paint chips: collect all layers of paint down to the substrate, approximately 1–2 cm² of material.
- For dust wipes: use approved collection wipes and follow specified surface area protocols.
- Place samples in clean, sealed containers, and label each with the sample ID and location.
- Use clean tape lifts, swabs, or air cassettes intended for mold analysis.
- Wear full protective gear (respirator with P100 filters, gloves, and coveralls).
- Avoid sampling in areas with excessive dust or unrelated debris.
- Do not collect visibly wet or dripping materials unless specifically required.
- Store samples in a cool, dry container and submit promptly to the laboratory.
To maintain sample traceability:
- Sampler Signature / Date / Time (at collection)
- Courier or Drop-Off Signature / Date / Time (if applicable)
- Laboratory Receiver Signature / Date / Time (upon receipt)
Each transfer must be signed and dated to preserve custody integrity.

Sample Collection Responsibility
The submitting party (homeowner or client) is fully responsible for sample collection, handling, labeling, and documentation. The laboratory does not provide sampling services and assumes no liability for the manner or adequacy of sampling procedures. -
Volume and Representativeness
The laboratory analyzes only the material received. It is the client's responsibility to ensure that the quantity, quality, and representativeness of samples meet the requirements for the intended analysis. -
Regulatory Compliance
Clients are solely responsible for ensuring that sampling activities comply with all WorkSafeBC, Health Canada, and applicable occupational health and safety regulations. The laboratory does not verify or enforce compliance with regulatory standards. -
Chain of Custody and Sample Integrity
The laboratory's responsibility begins only upon formal receipt of the samples in the laboratory. All samples must be accompanied by a completed Chain of Custody form. -
Analytical Scope and Reporting
Laboratory results apply only to the materials submitted and cannot be extrapolated to other unsampled locations or materials.
- All sample containers are labeled with unique IDs.
- The Chain of Custody form is complete and signed.
- Samples are sealed and packaged securely.
- Contact information and requested analyses are clearly indicated.
