Although dust and molds are natural and commonly found both indoors and outdoors, they can cause illness and allergic reactions for workers who are sensitive. The activity in your plant only increases the severity of the problem.
While total elimination of these contaminants is unrealistic, there are many ways to control the amounts that are present. Simple housekeeping habits and good maintenance practices can make a difference.
A regular maintenance program will remove dust and molds from trusses, beams, pipes, wiring, light fixtures, the outside of duct work and anything else you may have hanging up there.
