Western Health & Safety provides certified Environmental Tobacco Smoke (ETS) assessments as part of our Indoor Air Quality (IAQ) services across Alberta and British Columbia. Using indicators like 3-ethenylpyridine (3-EP), solanesol, and PM2.5, WHS evaluates secondhand smoke exposure risks in offices, schools, and multifamily dwellings. Our assessments align with research from the California Air Resources Board and Health Canada, and results support compliance with occupational health regulations and tenant air quality standards.
What is Environmental Tobacco Smoke (ETS) Exposure?
Environmental Tobacco Smoke (ETS), or secondhand smoke, is a hazardous mixture of gases and fine particles emitted from the burning of tobacco products. ETS has been classified as a toxic air contaminant by regulatory bodies including the California Air Resources Board (CARB). In indoor environments, ETS exposure can increase the risk of respiratory diseases, cardiovascular issues, and cancer, especially in children and vulnerable workers.
What is an environmental tobacco smoke assessment?
An environmental tobacco smoke (ETS) assessment detects and quantifies secondhand smoke exposure in indoor spaces. Western Health & Safety conducts ETS assessments using markers like 3-ethenylpyridine (3-EP), solanesol, nicotine, and PM2.5 to evaluate exposure risk. These assessments support compliance with occupational health and housing standards in Alberta and BC.
ETS Sampling & Analysis by Western Health & Safety
Western Health & Safety uses field-tested methods and laboratory analysis to quantify exposure to secondhand smoke. Our CIH-led assessments include:
- Air and surface sampling for 3-Ethenylpyridine (3-EP): A stable, vapor-phase ETS indicator.
- Particulate sampling for Solanesol: A tobacco-specific marker in the particulate phase.
- Nicotine and PM2.5: Measured to identify presence and load of airborne contaminants.
- Optional VOCs and Tobacco-specific nitrosamines (TSNAs) analysis: To support litigation, sensitive occupants, or policy enforcement.
