When is a Mold Complaint NOT a Mold Problem?
(Answer: Not often!)
Scott Lawson, CIH, President
The Lawson Group, Concord, NH
About this program:
When a mold problem is suspected in a building, the first reaction is often to start testing immediately. But what if mold isn’t the real problem?
In this session, we will discuss the benefits of engaging a proven process that investigates occupant complaints by treating them as indoor air quality issues, not mold problems, until the evidence says otherwise. Rather than assuming mold is the cause, we begin by treating all suspected IAQ issues with a systematic process to identify the true source of occupant complaints. While environmental testing and monitoring may be part of the investigation, they are used strategically when there appears to be a need - not as the starting point.
Drawing on decades of experience and hundreds of successful investigations, this presentation will demonstrate how a thorough, evidence-based process often reveals issues other than mold, leading to practical solutions that satisfy both building owners and occupants. Attendees will learn a system they can apply to each situation to confidently evaluate complaints, avoid unnecessary testing, and focus on resolving the underlying problem promptly.
Who Should Attend
This presentation is ideal for facility managers, building engineers, maintenance directors, human resources professionals, environmental health and safety staff, risk managers, and others responsible for responding to occupant complaints about indoor environmental quality. Anyone who investigates or manages concerns related to suspected mold, odors, or indoor air quality will benefit from this practical, real-world approach.
Learning Goals:
By attending this session, you will learn how to:
-
Deal with IAQ issues in a timely manner
-
Regard all IAQ complaints as valid
-
Routinely pay attention to HVAC/Mechanical system operation and maintenance
-
Pay proper attention to day-to-day housekeeping
-
Be proactive regarding IAQ in your own building - never assume that no complaints indicate that all is well
