Renovations are an essential part of building maintenance and improvement, but they often come with a hidden health risk: exposure to volatile organic compounds (VOCs). VOCs are chemicals emitted by many construction and finishing materials, including paints, adhesives, sealants, and flooring. These compounds can affect indoor air quality and pose health hazards to occupants and workers alike. For builders and contractors in Canada, minimizing VOC exposure during renovations is critical to ensuring safer environments and meeting green building standards. This blog explores practical strategies to reduce VOC emissions and protect health during renovation projects.
What Are VOCs and Why Are They a Concern?
Volatile Organic Compounds are a group of organic chemicals that easily vaporize at room temperature. Common VOCs include formaldehyde, benzene, toluene, and xylene. They are found in many building products such as:
Paints and varnishes
Adhesives and sealants
Carpets and flooring materials
Composite wood products
Cleaning agents
Exposure to VOCs can cause headaches, dizziness, respiratory irritation, and in some cases, long-term health effects including asthma and certain cancers. Indoor air can contain VOC levels significantly higher than outdoor air, especially during and shortly after renovation activities.
Strategies to Minimize VOC Exposure in Renovations
1. Select Low-VOC or Zero-VOC Products
One of the most effective ways to reduce VOC exposure is to choose products formulated with low or zero VOC content. Many manufacturers now offer paints, adhesives, and finishes certified for low emissions by programs such as Green Seal, GREENGUARD, or the Canadian VOC regulations.
Tips: Verify product VOC levels on technical data sheets and certifications before purchasing.
2. Increase Ventilation During and After Renovation
Proper ventilation helps dilute and remove VOCs from indoor air. Opening windows, using exhaust fans, and employing mechanical ventilation systems can significantly reduce VOC concentrations.
Tips: Plan for extended ventilation after applying finishes; use air scrubbers or filters where possible.
3. Use Alternative Materials
Where possible, substitute high-VOC materials with more sustainable options. For example, use natural fiber carpets instead of synthetic ones, or water-based adhesives instead of solvent-based.
4. Implement Proper Storage and Handling
Store VOC-containing products in tightly sealed containers and in well-ventilated areas to limit off-gassing. Follow manufacturer guidelines for safe handling and disposal.
5. Schedule Work to Minimize Occupant Exposure
Plan renovation activities when buildings are unoccupied or least occupied to reduce exposure risks. If occupants must remain, isolate work areas with temporary barriers and maintain ventilation.
6. Educate and Train Workers
Ensure construction teams understand the risks of VOC exposure and best practices for minimizing it, including use of personal protective equipment (PPE) like respirators and gloves.
