Veterinary clinics: air quality assessment & public health protection

What pollutants do we measure in our assessment of your veterinary clinic?

Pollutants specific to veterinary clinics

• Halogenated anesthetic gases (isoflurane/sevoflurane): These neurotoxic and hepatotoxic substances pose risks to reproduction. Although there is currently no French Occupational Exposure Limit (OEL), we follow the strict recommendation from NIOSH (less than 2 ppm).
• Formaldehyde: used in biopsies, histology, and the preservation of anatomical specimens, it is a known carcinogen (classified as Group 1 by the IARC). The assessment verifies strict compliance with the OEL set at 0.3 ppm by the May 2023 decree.
• Animal-derived contaminants: measurement of allergens (dog and cat dander), bacteria, and endotoxins, which can cause occupational asthma, rhinitis, or pneumonia among healthcare workers.
• Disinfectants and VOCs (Volatile Organic Compounds): Analysis of residues of quaternary ammonium compounds, glutaraldehyde, or chlorhexidine, which cause chronic respiratory tract irritation.
• Lockdown and CO₂: Assessing air exchange rates in enclosed spaces. CO₂ levels above 1,000 ppm can cause fatigue and headaches for your staff and customers.
• Aerosolized medications: monitoring of chronic exposure to low doses (antibiotics, antiparasitic drugs, hormone sprays) that may act as potential endocrine disruptors or CMRs (carcinogens, mutagens, and reproductive toxins).

Mapping Air Quality Risks by Veterinary Area

Each area of your facility has its own pollution profile. Our assessment helps you prioritize actions:

Occupational Hazards in Veterinary Clinics: Who Is Exposed to Air Pollution?

Occupational exposure to hazardous chemicals in veterinary clinics is one of the most underreported risks in the medical sector.
According to the INRS, veterinarians and their assistants face a combination of chemical, biological, and physical risks that remain largely unreported due to a lack of documented workplace assessments.

• Surgeons (exposure 8–9 hours/day): neurotoxic effects associated with chronic inhalation of isoflurane and sevoflurane (headaches, working memory impairments, cognitive fatigue at the end of the day). Critical reproductive risk: these halogenated gases cross the placental barrier (miscarriages and birth defects suspected by NIOSH).
• Veterinary Assistants & Support Staff (shared exposure, 6–8 hours/day): chronic eye and respiratory irritation caused by anesthetic residues and disinfectants. Significant risk of occupational allergic asthma (a condition documented after 3 to 5 years of exposure) and respiratory zoonotic risks (scaling aerosols spreading bacteria, Pasteurella, Bordetella).
• Laboratory staff / Laboratory technicians: handling formaldehyde during biopsies and histology procedures. Proven carcinogenic risk (IARC Group 1) leading to nasopharyngeal cancer and myeloid leukemia, requiring enhanced monitoring.
• Reception staff: constant exposure to animal allergens (dander), CO₂, and airborne biocontaminants. An allergic risk that is still too often underestimated.

Recognition as an occupational disease

These exposures are directly related to items No. 43 (aldehydes), No. 45 and No. 66 (allergic asthma and respiratory disorders), and No. 84 (organic solvents) of the general regulations.

Glossary of Terms Related to Veterinary Indoor Air Quality (IAQ) Regulations

• 8-hour OEL / OEL: occupational exposure limit (8-hour average) at the workstation.
• CMR: carcinogenic, mutagenic, or toxic to reproduction.
• MSDS: Material Safety Data Sheet for the chemical product; required at the workplace.
• CPE / PPE: collective protective equipment (priority) / personal protective equipment.

Summary of Exposure Limits and Risks in Veterinary Practice

What does the NatéoSanté diagnostic report NatéoSanté a veterinarian include?

To support you in implementing this action plan, ensure compliance, and protect your staff, our comprehensive audit provides you with concrete, actionable scientific data:

• Continuous 7-day monitoring: precise analysis of the presence of isoflurane, formaldehyde, VOCs, biocontaminants, and CO₂ in each room.
• Expert analysis and AI: Our algorithms cross-reference your results with our 15 years of veterinary expertise data to identify your specific risks.
• Detailed graphs: clear visualization of exposure peaks throughout the week, direct comparison with legal thresholds, and identification of pollution sources.
• Data ready for the DUERP: You’ll receive key indicators—quantified and official—ready to be incorporated directly into your Single Document to demonstrate your due diligence.
• Eolis Air Manager Recommendation: a customized recommendation for the exact air purifier model and filter configuration tailored to your specific pollutants.

Case Study: From Assessment to Compliance for a Typical 25-Square-Meter Clinic

This representative case is drawn from the NatéoSanté database, which contains 15 years of QAI diagnoses in the veterinary field.

The context of the case study on air quality in a veterinary clinic

A suburban veterinary clinic (2 veterinarians, 1 veterinary assistant, ~120 procedures/week) has a 25-square-meter surgical suite equipped with a recently installed single-flow mechanical ventilation system.
The team performs 6 to 8 surgeries per week under general anesthesia (isoflurane), as well as dental scaling and formalin-fixed biopsy preparations.

The trigger

Veterinarians experience recurring headaches at the end of the day, veterinary assistants suffer from eye irritation, and there are persistent odors.
Management wishes to objectively assess the situation for the DUERP prior to an inspection by the Labor Inspectorate.

The diagnosis: 7 days of continuous monitoring

An Air Coach Pro sensor measured air quality every 5 minutes under real-world conditions, without altering the team’s routine. The overall exposure index was 52/100 (Poor air quality).

• Anesthetic gases (isoflurane), non-compliant: Maximum peak of 8.5 ppm during induction, which is 4.2 times the NIOSH recommendation (2 ppm). Average of 1.8 ppm during the hours of surgery.
• Formaldehyde, non-compliant: maximum peak of 95 µg/m³ during biopsy preparation, which is 3.2 times the 8-hour VLEP threshold (Decree 2011-1727). The pollutant persisted for 2 to 3 hours after the vials were opened.
• Fine particulate matter (PM2.5), non-compliant: maximum peak of 35 µg/m³ during ultrasonic scaling, which is 2.3 times the WHO threshold. These aerosols of tartar and saliva are vectors for respiratory zoonoses.
• Indoor air quality (CO₂): compliant; maximum peak of 880 ppm (below the regulatory threshold of 1,000 ppm).

The Pitfall of Code-Compliant Mechanical Ventilation

This assessment highlights a classic pitfall: mechanical ventilation removes CO₂ (a light gas), but not chemical hazards.
Isoflurane (4.7 times heavier than air), formaldehyde, and scaling aerosols accumulate in the practitioners’ breathing zone.
The team believed they were protected by compliant ventilation, even though 3 out of 4 critical pollutants were at severely elevated levels.

Our recommendation: Eolis Air Manager 600 S

Given this typical profile (high chemical load and persistent pollutants), our AI decision matrix recommends installing an Eolis Air Manager 600 S equipped with a VET filter to supplement the existing ventilation system.

• Optimal airflow (CADR 350 m³/h): provides complete air circulation 7 times per hour in a 25 m² room.
• The exclusive VET Filter: combines a HEPA H13-certified filter media (EN 1822 standard) to capture 99.97% of anesthetic particles and allergens, and high-density activated carbon specifically designed to target isoflurane, sevoflurane, and formaldehyde.
• Deep Clean Technology: a patented active decontamination feature (Air + Surfaces) that can be programmed to run overnight, essential for eliminating residual formaldehyde.
