Vehicle Drug Testing & Decontamination

Background

A recovered stolen vehicle may need drug residue testing before a repair shop begins work or an insurer decides the next step. Testing can also help assess suspected previous drug use, unexplained residue or a vehicle being considered for purchase. A clean-looking interior does not establish whether drug residue is present.

You can book initial testing without committing to cleaning. We also test vehicles after cleanup by another provider. Findings help define the affected areas and the work needed.

​

Seats, Carpets & Other Interior Materials

Cleaning can offer an alternative to extensive interior replacement, particularly when parts are costly or unavailable. We consider seats, carpets, headliners, trim, storage areas and accessible HVAC components when planning the job. The substance detected, material and access affect the treatment selected.

The scope and completion criteria are confirmed before work starts. Where a component cannot be adequately accessed or treated, we discuss replacement with the customer or repair facility. Mechanical repairs and electrical work are arranged separately.

​

Truck Cabs & Sleeper Compartments

Bunks, lockers, flooring and trim can conceal contamination or restrict access. Send photos, earlier reports and details of any dismantling already completed so we can identify what needs to be prepared by the repair facility.

We also review other difficult interior contamination and persistent odours. Acceptance depends on the source, materials and access. Rodent-related vehicle projects are handled through body shops, collision centres or insurance companies.

Cleaning & Decontamination Process

Scenesafe's proprietary cleaning method is a major improvement in our vehicle decontamination work. Further use on real projects has confirmed much faster cleaning and more effective drug residue removal than conventional spray extraction alone, including on porous carpets and fabric seats. The specific method is commercially confidential. We check the results through post-cleaning drug residue testing, with negative results required for completion.

​

1. Review the vehicle and access. Tell us the vehicle type, location and reported contamination. Photos, earlier test reports and details of dismantling help us identify what the repair facility needs to prepare. We confirm who can authorize the work and receive the report.

​

2. Test and define the scope. For most vehicles, we use one rapid surface test panel for an overall initial screen and ScenoMS field mass spectrometry to test samples from individual locations. Scenesafe determines how the two methods are combined for each vehicle.

​

Sampling locations are selected for each vehicle and may include:

• Keys

• Seats

• Carpets

• Steering wheel

• Door handles

• Cabin air filter

• Door storage pockets

• Centre console area and storage compartment

• Glove box

• Headliner

Initial findings guide the areas and materials included. We discuss access, any components that may need replacement, the treatment plan and post-cleaning acceptance criteria before work begins.

​

3. Clean and reassess. Treatment may include appropriate commercial and custom-formulated cleaning agents, steam cleaning and repeated treatment of affected materials. Testing during the job guides further cleaning. Seats, carpets, headliners, trim, doors and cargo areas are included where specified in the cleaning plan. HVAC work is limited to components that can be accessed and treated; we discuss filter replacement and any further dismantling needed.

​

4. Complete testing and drying. We sample the locations identified in the testing plan after cleaning. Further treatment is needed where results do not meet the completion criteria. Interior dehumidification and odour treatment are used where appropriate to the job. We provide a Statement of Completion of Decontamination when the completion criteria are met.

No additional long-distance travel charge applies to jobs within Halifax Regional Municipality or Colchester County. Service charges still apply. Outside these areas, any travel charge is confirmed as part of your quote.

Post-Decontamination Testing

After cleaning, we test selected locations for the target substances and document the findings. Our decontamination standard is to clean drug residues to below the detection limits of the selected test methods. Completion requires non-detect (negative) results. Positive findings guide further cleaning and retesting.

Samples are collected using a 10 cm × 10 cm surface sampling area and analysed using test kits or Field MS, according to the substances initially identified. The selected methods and their detection thresholds form the basis of our company’s acceptance criteria.

For Field MS, we use our own-brand ScenoMS portable mass spectrometer supplied by specialist manufacturing partners. We do not use other brands’ portable mass spectrometers or ion mobility spectrometry (IMS) instruments. Hands-on comparisons and research guide our equipment choices, and we share field findings with our suppliers and manufacturers to support improvements.

As technical examples under the applicable sampling and testing conditions, approximately 0.44 nanograms of fentanyl (FEN) collected from a 100 cm² surface area may trigger a positive result; the approximate positive threshold for cocaine (COC) is 2.2 nanograms. Thresholds vary by substance and method and are not measurements of exposure or health risk.

See our ScenoMS field mass spectrometer for device information. Detection thresholds depend on the selected test method. Rapid test kit cut-offs depend on the kit and panel used and are expressed in nanograms per millilitre (ng/mL). Refer to the instructions for the kit used.

Completion and Scope

Completion requires negative post-cleaning results for the target substances at the sampled locations, using the selected test methods. We provide a Statement of Completion of Decontamination recording the work and results. Areas that could not be accessed or treated, and any recommended replacement, are recorded in the project documentation.

​

Does every recovered stolen vehicle need decontamination?

Initial testing helps determine whether drug residue is detected and what work is needed. You can request testing before deciding on cleaning.

Can fabric seats and carpets be cleaned?

Our method is used on porous interior materials, including fabric seats and carpets. We assess the material and access, then check the outcome through post-cleaning testing. Replacement is discussed where treatment is not suitable or the completion criteria cannot be met.

Can a body shop or insurer arrange the work?

Yes. Send the vehicle details, location, available reports and photos, claim reference where applicable, and the contact authorized to approve the work. We can quote initial testing, cleanup or testing after another provider has cleaned the vehicle.

What affects price and turnaround?

Vehicle size, contamination, materials, access and the testing required affect the quote. Dismantling, repeat treatment and drying can affect the schedule. A testing report timeframe is separate from the time needed to complete a cleanup.
