In this episode Mark Reggers discusses clandestine laboratories with guest Brad Prezant. Brad, an occupational hygienist, is the Chief Scientific Officer for ValidAir Sciences. Clandestine Laboratories, also known as clan labs, or by their more common term Meth labs are used for the manufacture of illegal drugs such as methamphetamine. These labs pose a serious risk to the community due to the hazardous toxic chemicals generated during the drug manufacturing process. The by-products of meth labs can contaminate buildings, furniture, soil, water, and air within or close to the clan lab site with harmful fumes and highly explosive chemical compounds that impact both health and the environment.
