Understanding Mold Classifications
Mold is generally classified into three hazard classes based on the health risks they pose:
Allergenic
Has been associated with mild allergic responses and may aggravate asthma symptoms in sensitive individuals.
Pathogenic
Has been associated with infections, particularly in individuals with weakened immune systems or underlying conditions.
Toxigenic
Can produce mycotoxins under certain conditions. Health effects vary and depend on the individual and exposure.
Stachybotrys Chartarum
Also known as: Black Mold
Dark Green / Black
High-cellulose materials like drywall, paper, and wood that have stayed wet for several days.
Can produce mycotoxins. Has been associated with respiratory irritation and allergic-type responses in some individuals.
Aspergillus
Also known as: Common Indoor Mold
Yellow / Green / White / Black
Dust, powdery surfaces, HVAC systems, and damp walls.
May cause allergic reactions and respiratory irritation. Some species have been associated with infections in individuals with weakened immune systems.
Penicillium

Water-damaged materials, wallpaper, carpets, and decaying fabrics.
Has been associated with allergic reactions, asthma flare-ups, and chronic sinus irritation in sensitive individuals.
Cladosporium
Also known as: Outdoor/Indoor Mold
Olive Green / Brown / Black
Fabrics, wood surfaces, cooling coils, and damp window sills.
Has been associated with allergy symptoms, skin rashes, and eye irritation. Can grow in cooler temperatures.
Alternaria

Showers, under leaking sinks, and areas with extensive water damage.
Has been associated with asthma flare-ups and allergic responses in sensitive individuals.
Chaetomium
Also known as: Water-Damage Mold

Severely water-damaged drywall, baseboards, and carpets. Often found alongside Stachybotrys.
Produces a strong musty odor. Has been associated with allergic reactions and respiratory irritation in sensitive individuals.
