I was recently interviewed by Connect Media about “unseen” industrial hygiene concerns that can have an impact on human health of property occupants and potentially incur liabilities for owners and investors. By far the biggest concerns lurking in walls, floors and the air are biological concerns like mold/fungus/bacteria, radon gas and other chemicals, and asbestos. All of these collectively contribute to the indoor air quality (IAQ) of a space. Consulting with a certified industrial hygienist and performing regular building assessments and other inspections can go a long way towards proactively protecting your property and the people that inhabit it.
