Hazardous Materials Abatement

We abate material identified in the project survey or consultant specification, including lead coatings, mercury devices, silica-bearing deposits, chemical residues, contaminated insulation, fuel residues, biological debris, and other hazardous building or process materials. Each substance receives its own control, cleaning, packaging, and waste route based on its properties and Ontario requirements.

No. Asbestos work follows the operation types and detailed procedures in O. Reg. 278/05. Other hazardous materials can present vapour, skin, ingestion, fire, reactivity, or environmental risks that require different ventilation, tools, protective equipment, and packaging. A project containing several materials needs separate procedures coordinated within one construction sequence.

We compare surveys and process records with drawings, equipment labels, service routes, and selective openings. Suspect material is not disturbed until its identity and extent are established. The consultant can direct sampling, and Harrowgate then updates containment, quantity, method, waste class, and schedule before controlled removal resumes.

Yes, with facility-approved isolation and phasing. We coordinate process shutdowns, ventilation, deliveries, emergency routes, energized systems, and production windows. Sealed work zones, local capture, protected waste routes, and daily handback criteria limit interference. The chosen method must suit the material and process environment, especially where vapours or ignition sources are possible.

Packaging matches the material’s chemistry, physical state, and receiver requirements. Options include sealed drums, overpacks, lined bins, pails, wrapped components, or compatible liquid containers. Waste is labelled, protected, and segregated from incompatible streams. Disposable protection, filters, absorbents, and cleaning residues are classified with the contamination they contain.

Verification follows the project specification and may include a detailed visual inspection, air sampling, surface wipe testing, moisture or gas readings, and laboratory analysis. Harrowgate completes progressive cleaning and presents the work area at the defined hold point. Temporary controls remain until the consultant or client representative accepts the required result.

Closeout records can include location logs, daily reports, containment and pressure checks, worker and equipment entries, sampling results, package counts, digital manifests, receiving confirmations, photographs, and consultant acceptance. Harrowgate reconciles these records against the original survey so remaining known materials and completed areas are clearly distinguished.
