Identify & Measure Workplace Health Hazards
Preventis's certified occupational hygienists identify physical, chemical, and biological hazards, assess exposure risks, and design control programs fully aligned with Quebec's occupational health legislation.
Why Industrial Hygiene Matters
Workplace exposure to hazardous agents—whether chemical, physical, or biological—can lead to serious short- and long-term health consequences if not properly controlled. Our approach helps employers meet their strict obligations under Quebec’s occupational health and safety framework while proactively protecting their workforce.
Preventis System supports organizations across Quebec by:
Identifying health hazards in the work environment.
Measuring employee exposure using precise, calibrated instruments.
Designing practical, sustainable control strategies.
Evaluating compliance with legislated exposure limits.
Our Industrial Hygiene Services
Hazard Identification & Exposure Risk Assessment
Our occupational hygienists evaluate work environments to identify factors that may negatively impact workers’ health. Each assessment follows a standardized, legislated, and evidence-based methodology, ensuring reliable results and defensible decisions.
Sampling of Physical, Chemical, and Biological Contaminants
Preventis experts perform on-site sampling using calibrated industrial hygiene instruments. To ensure absolute accuracy and regulatory credibility, all samples are analyzed by accredited laboratories.
We sample and assess exposure to a wide range of contaminants, including:
Volatile Organic Compounds
Asbestos
Beryllium
Diesel Exhaust
Gases and vapours
Formaldehyde
Solvents
Lead
Noise Management & Hearing Conservation Programs
Noise exposure is a major occupational hazard that can cause permanent hearing loss and broader health effects. Health impacts of noise exposure include:
Auditory Effects
Noise-Induced Hearing Loss (NIHL), tinnitus, and acoustic trauma.
Non-Auditory Effects
Cardiovascular risks (hypertension, heart disease), psychological stress, anxiety, sleep disorders, reduced productivity, and increased safety risks.
The Preventis Noise Control Approach
Our occupational hygiene technicians design Hearing Conservation Programs using the standard hierarchy of controls, prioritizing permanent solutions. Our programs perfectly align with CSA Z94.2 and applicable Quebec regulations.
- Elimination / Substitution
Removing or replacing noisy equipment.
- Engineering Controls
Installing barriers, enclosures, or vibration isolation.
- Administrative Controls
Implementing task rotation, scheduling, and quiet zones.
- Personal Protective Equipment (PPE)
Providing earplugs or earmuffs, complete with fit testing when required.
Heat Stress Assessment & Management
Heat stress is a growing occupational risk, particularly in heavy industrial and outdoor work environments. This proactive approach helps prevent heat exhaustion, heat stroke, and costly productivity losses.
Identifying and mapping heat exposure hotspots by task and location.
Evaluating work/rest cycles and metabolic workloads.
Factoring in environmental conditions and individual risk factors.
Recording findings directly in the Preventis software platform.

Frequently Asked Questions
What is industrial hygiene?
Industrial hygiene focuses on identifying, measuring, and controlling workplace hazards that may affect workers’ health. This includes managing exposure to chemical, physical, and biological agents.
Are your services compliant with Quebec regulations?
Yes. All Preventis industrial hygiene services are specifically designed to meet Quebec’s legislated exposure standards and CNESST regulatory requirements.
How are industrial hygiene samples analyzed?
All collected samples are sent to independent, accredited laboratories to ensure the results are reliable, accurate, and legally defensible.
Can our hygiene results be accessed online?
Yes. All data, reports, and recommendations are securely stored and easily accessible through the Preventis Occupational Health software module.
Do you only measure hazards, or do you help control them?
We do both. Preventis not only measures exposure but also designs and supports the implementation of effective, real-world control programs to protect your workers.
