OHS & Hygiene
Industrial Hygiene
Our certified Industrial Hygienists help organizations identify chemical, physical, biological, and environmental hazards before they impact employee health. Workplace exposures to toxic dusts, chemical vapors, excessive noise, mold, asbestos, radiation, and extreme temperatures pose severe long-term health risks and major regulatory liabilities.
We combine advanced sampling technology with deep regulatory expertise to conduct thorough exposure assessments, design engineering controls, and implement compliant conservation programs—keeping your workforce safe and your operations fully compliant with provincial and national health standards.
Core Industrial Hygiene Programs
Our strategic industrial hygiene consulting services empower businesses to systematically measure, control, and eliminate environmental and occupational health risks.
Occupational / Industrial Hygiene Program Development
- Custom Framework Design: Building comprehensive, site-specific hygiene programs to systematically evaluate, monitor, and control hazardous workplace exposures.
- Hazard Inventories: Developing centralized inventories of chemical, physical, biological, and radiological agents present across your operational facilities.
- Regulatory Compliance: Ensuring your health management programs fully comply with provincial Occupational Health & Safety exposure limits (OELs/TLVs).
Workplace Exposure Assessments & Air Monitoring
- Chemical & Airborne Hazard Sampling: Quantitative testing for airborne contaminants, including volatile organic compounds (VOCs), solvents, heavy metals, welding fumes, and toxic gases.
- Particulate & Dust Evaluation: Sampling for respirable and total dusts, hazardous particulate matter, and biological aerosols in manufacturing and processing environments.
- Baseline & Periodic Exposure Profiling: Establishing baseline exposure profiles for high-risk job roles to guide engineering controls and personal protective equipment (PPE) selection.
Indoor Air Quality (IAQ) & Mold Assessments
- IAQ Hazard Investigations: Investigating occupant complaints regarding poor air circulation, odors, humidity issues, and “sick building syndrome” parameters (, , temperature, humidity).
- Mold & Microbial Testing: Conducting visual inspections, surface swab sampling, and indoor/outdoor air sampling to identify mold spores and moisture intrustion points.
- Remediation Protocols: Writing step-by-step containment and scope-of-work protocols for safe fungal and microbial abatement.
Ventilation Assessment & Control Design
- Local Exhaust Ventilation (LEV) Testing: Evaluating capture velocity, hood static pressure, duct airflow, and overall efficiency of local exhaust systems to ensure hazardous fumes and dusts are contained.
- General HVAC & IAQ Reviews: Assessing general dilution ventilation rates to maintain healthy indoor air quality and prevent air contaminant buildup.
- Engineering Control Recommendations: Providing clear engineering design strategies to repair, upgrade, or reconfigure ventilation systems for maximum contaminant capture.

Noise Assessments, Surveys & Hearing Conservation
- Sound Level Mapping: Conducting comprehensive plant-wide noise surveys to map noise levels and identify high-decibel hazard zones.
- Personal Noise Dosimetry: Measuring individual noise exposures across full work shifts to identify employees exceeding regulatory Noise Exposure Limits (85 dBA 8-hr TWA).
- Hearing Conservation Program Support: Designing complete hearing conservation protocols, including engineering noise controls, hearing protection device (HPD) attenuation evaluations, and audiometric testing integration.
Hazardous Materials & Designated Substances Management
- Designated Substance Surveys (DSS): Performing legally mandated facility inspections and sampling for Designated Substances (asbestos, lead, silica, mercury, benzene, etc.) prior to renovation or demolition projects.
- Asbestos & Lead Management Plans: Drafting site-specific management plans, air monitoring protocols during abatement, and clearance inspections following hazardous material removals.
Silica Exposure Monitoring & Control Plans
- Respirable Crystalline Silica (RCS) Air Sampling: Collecting personal and area air samples to measure crystalline silica dust levels during concrete cutting, grinding, quarrying, and construction operations.
- Exposure Control Plan (ECP) Development: Drafting mandatory Exposure Control Plans that outline dust suppression methods, specialized vacuum attachments, local exhaust ventilation, and mandatory PPE.
Thermal Stress & Microclimate Monitoring
- Heat & Cold Stress Evaluations: Measuring Wet Bulb Globe Temperature (WBGT) indices and wind-chill factors to assess worker risk in foundries, bakeries, outdoor operations, and cold storage facilities.
- Work-Rest Regimen Design: Developing customized work-rest schedules, hydration protocols, and acclimatization strategies to prevent heat stroke, heat exhaustion, and frostbite.
Radiation & Non-Ionizing Energy Monitoring
- Non-Ionizing Radiation Surveys: Assessing workplace exposure levels to electromagnetic fields (EMF), radiofrequency (RF) radiation, lasers, and ultraviolet (UV) radiation.
- Ionizing Radiation Safety Support: Establishing safety protocols and monitoring plans for operations using x-ray equipment, industrial radiography, or radioactive sources.
Respiratory Protection Program Development
- Custom Program Writing: Developing written, compliant Respiratory Protection Programs detailing proper respirator selection, use, cleaning, maintenance, and storage.
Fit Testing Protocols: Administering quantitative and qualitative respirator fit testing to ensure proper seal integrity and worker safety.
