⚠️ Risk Characterization (Fentanyl, Meth, Heroin, etc.)WHS CIHs evaluate health risks based on the type of drug, concentration levels, surface loadings, and exposure pathways—particularly where children, tenants, or workers may be affected.
🧼 Cleaning Protocols & Contractor Oversight - We provide detailed remediation guidance tailored to site conditions and drug type. Our hygienists can also oversee third-party cleanup crews to ensure compliance with recognized protocols (e.g., ASTM E2458, AIHA guidance).
✅ Clearance Testing & Certification - Post-cleanup, we conduct verification sampling and issue formal clearance documentation, confirming the site meets safety thresholds for re-occupancy.
👷 Worker Exposure Monitoring - When required, we monitor airborne levels of hazardous residues during cleanup, protecting remediation workers and ensuring compliance with occupational exposure limits (OELs).

Regulations and Health Risks
Illicit drug residue cleanup is more than a cleaning task — it’s a regulated occupational health and safety responsibility that can impact both worker safety and legal compliance.
⚖️ Alberta OHS Requirements - Under Alberta’s Occupational Health and Safety (OHS) legislation, fentanyl and other illicit drugs are recognized as workplace hazards. Employers have a legal duty to:
📋 WorkSafeBC Requirements - In British Columbia, an Exposure Control Plan (ECP) is required under WorkSafeBC regulations when workers face the risk of exposure to toxic substances like fentanyl or meth. Your ECP must include:
⚖️ Alberta OHS Requirements - Under Alberta’s Occupational Health and Safety (OHS) legislation, fentanyl and other illicit drugs are recognized as workplace hazards. Employers have a legal duty to:
- Conduct hazard assessments if workers may encounter drug-contaminated spaces.
- Implement controls, including PPE, administrative procedures, and emergency response plans.
- Provide training on handling opioid exposure risks and safe work practices.
- Address impairment from any source as a safety concern.
- Decide on naloxone use and train staff accordingly if kits are supplied.
📋 WorkSafeBC Requirements - In British Columbia, an Exposure Control Plan (ECP) is required under WorkSafeBC regulations when workers face the risk of exposure to toxic substances like fentanyl or meth. Your ECP must include:
- A clear risk assessment
- Detailed control measures
- Training and education protocols
- A defensible post-cleanup clearance process
- Acute health effects such as dizziness, breathing difficulty, or unconsciousness
- Chronic exposure risks including cognitive or neurological impacts
- Cross-contamination risks to new occupants or cleanup personnel
Frequently Asked Questions
❓ How do I know if my property is contaminated with drug residue?
If the property has a history of drug use, overdose, or law enforcement activity, contamination is possible. Residues may not be visible, and even trace amounts of fentanyl or methamphetamine can pose health risks. Western Health & Safety provides certified surface sampling to determine contamination levels.
❓ What types of testing are available for fentanyl or methamphetamine?
WHS uses validated surface sampling methods aligned with ASTM and AIHA guidance. These tests can detect trace levels of:
- Fentanyl and analogs
- Methamphetamine
- Heroin and opioid byproducts
Results are interpreted by Certified Industrial Hygienists to determine if remediation is required.
❓ Can a property be re-occupied after fentanyl cleanup?
Yes — but only after proper assessment, decontamination, and final clearance testing. WHS issues formal clearance documentation that confirms safety thresholds have been met and the space is suitable for occupancy.
❓ Is this service covered by insurance?
In many cases, yes. Property insurance may cover drug contamination cleanup under hazardous materials or biohazard clauses. We recommend contacting your insurer with WHS documentation to support your claim.
❓ What’s included in an Exposure Control Plan (ECP)?
If your workplace involves possible drug exposure (e.g., cleanup crews, restoration teams, first responders), WorkSafeBC and Alberta OHS may require an ECP. WHS prepares ECPs that include:
- Hazard assessments
- Control strategies (PPE, work practices)
- Emergency response procedures
- Worker training and documentation
❓ Can Western Health & Safety oversee cleanup contractors?
Absolutely. WHS offers remediation oversight and post-cleanup verification, ensuring that third-party cleaners follow defensible, regulated protocols.
❓ Do I need naloxone kits at my workplace?
Employers in Alberta can choose whether to provide naloxone, but must conduct a hazard assessment and offer proper training if kits are supplied. WHS helps assess site risk and can integrate naloxone policies into your workplace procedures.
Illicit drug contamination — especially from fentanyl or methamphetamine — poses serious risks to health, safety, and legal compliance. Whether you're managing a residential unit, overseeing a restoration project, or responding to a public health concern, Western Health & Safety delivers certified assessments, defensible documentation, and CIH-led remediation oversight across Alberta and British Columbia.
