Molds need food, water and moisture to survive; since molds can digest most things, water or moisture is the factor that limits mold growth. Molds will often grow in damp or wet areas indoors. Common sites for indoor mold growth include bathroom tile, basement walls, areas around windows, wood, and some types of drywall where moisture condenses, damp attic spaces, and near leaky water fountains or sinks. Common sources or causes of water or moisture problems include roof leaks, deferred maintenance, condensation associated with high humidity or cold spots in the building, localized flooding due to plumbing failures or heavy rains, slow leaks in plumbing fixtures, and malfunction or poor design of humidification systems. Uncontrolled humidity can also be a source of moisture leading to mold growth, particularly in hot, humid climates.
All mold types have the potential to cause harmful health effects. Molds produce allergens, irritants, and in some cases, toxins that may trigger adverse reactions in humans. The types and severity of symptoms depend, in part, on the types of mold present, the extent of an individual's exposure, the ages of the individuals, and their existing sensitivities or allergies. There is a direct correlation between indoor mold exposure and human disease.
The work should be performed in a controlled environment, which consists of isolating the work area with a plastic room encompassing the affected mold areas and installing an air filtration device of sufficient size equipped with a high efficiency particulate air (HEPA) filter. The Workers should be dressed in disposable uniforms and wear the required respiratory protection. The purpose of the mold containment and the proper respiratory protection is to prevent facility occupants or home owners and the remediater from being exposure to mold in the air.
American Environmental Construction, because of its background and expertise in dust control and abatement procedures, is well placed to safely mitigate mold projects in the residential and commercial market place.
