Some Surprising Sources of IAQ Problems and Novel Ways to Sample Mold
Jeffrey May, IAQ Investigator, CIAQP CMC, May Indoor Air Investigations, LLC, Tyngsborough, MA
About this program:
For the last twenty-five years, I have investigated thousands of homes, schools, and offices spaces; and have examined by microscopy over 40,000 air and dust samples. Despite the many years I have spent as an IAQ investigator, I have been surprised by some of the indoor sources of allergens in of my investigations. I will discuss some of my more interesting IAQ cases, which include exposures from couches, carpets, bedding, and even clothing. I will describe several novel ways to gather samples, including the use of Air-o-Cell cassettes with a Scotch tape medium. My presentation will include case studies, photographs of conditions I have observed, and micrographs from samples that I examined. My focus is pragmatic rather than theoretical, and I invite anyone interested in IAQ to attend. I hope to teach people new ways of thinking about and approaching IAQ problems.
Learning Goals:
-
To recognize that mechanical equipment can be a powerful source of IAQ problems.
-
To identify sources of IAQ problems that occupants introduce into the building envelope.
-
To take a sample from a wall cavity without making a hole in the wall.
-
To take a source sample using an inexpensive mini-vacuum along with Scotch Tape in a cassette.
-
To understand that air sampling alone is not sufficient in an IAQ investigation; source sampling must be included.
