Indoor Air Quality Assessment
Indoor Air Quality (IAQ) problems result from interactions between building materials and furnishing, activities within the building, climate, and building occupants.
Indoor Air Contaminants
Here are examples of common indoor air contaminants and their main sources:
- Carbon dioxide (CO2), tobacco smoke, particulate matter, carbon monoxide, Temperature, Relative Humidity – from building occupants
- Dust, fibreglass, asbestos, gases, including formaldehyde – from building materials
- Toxic vapours, volatile organic compounds (VOCs) – from workplace cleansers, solvents, pesticides, disinfectants, glues
- Gases, vapours, odours – off-gas emissions from furniture, carpets, and paints
- Dust mites – from carpets, fabric, foam chair cushions
- Microbial contaminants, fungi, moulds, bacteria, – from damp areas, stagnant water and condensate pans
- Ozone – from photocopiers, electric motors, electrostatic air cleaners
LAW Environmental Consultants staff has conducted industrial hygiene and occupational health assessment for various industries across Canada and overseas. The indoor air quality program includes but not limited to:
- Sampling for physical agents including humidity, temperature, noise and vibration;
- Sampling for biochemical agents such as carbon monoxide, carbon dioxide, ozone, formaldehyde, VOCs, and moulds;
- Fibre sampling and identification and respirable dust sampling
- Carbon dioxide as a ventilation indicator;
- Multi-chemical analyses scanning close to 100 compounds for trace concentrations;
In collaboration with joint health and safety committee members we listen to worker concerns and complaints and discuss issues and recommend
Solutions and provide input into existing and proposed workplace health and safety programs to full satisfaction of management and labour.
