Airborne contaminants in the indoor environment can be detrimental to occupant’s comfort, health and labour productivity. Our team of experts provide a qualified, independent measuring and advisory service in the field of indoor environmental quality (IEQ). Individual analysis of the indoor environmental situation is appropriate in the case of existing health problems caused by the poor quality of indoor air, or for systematic prevention and avoidance of health risks arising from the presence of pollutants in indoor air. Effective steps can thus be taken to improve the quality of indoor air. Our Occupational hygienists are recognised by the Swiss Federal Coordination Commission for Occupational Safety (FCOS) as occupational safety specialists in terms of the ASA qualification ordinance. They work together with chemists, biologists and physicians. Indoor air tests can be conducted at manufacturing facilities and offices, in sales premises, homes, schools, hospitals, museums and other public buildings. Certification of the indoor environment in terms of the international Health Friendly Air programme is exclusively offered in Switzerland, Austria and Germany.
