  • Hazard Class A: includes fungi or their metabolic products that are highly hazardous to health. These fungi or metabolites should not be present in occupied dwellings. Presence of these fungi in occupied buildings requires immediate attention.
  • Hazard class B: includes those fungi which may cause allergic reactions to occupants if present indoors over a long period.
  • Hazard Class C: includes fungi not known to be a hazard to health. Growth of these fungi indoors, however, may cause economic damage and therefore should not be allowed.

Types Of Mold Categorized By Health Effects

Know The Different Types Of Molds
  • Allergenic molds affect people who have certain allergies or asthma. When people who are allergic to mold are exposed to it, they have a hypersensitive reaction, during which an excessive number of mast cells are activated, resulting in an extreme inflammatory response in the respiratory system. About 20%-30% of the population is susceptible to mold and/or other allergens, which can lead to reactions like allergic rhinitis. Most people without allergies are unaffected by allergenic molds in small amounts.
  • Pathogenic molds are capable of causing certain infections or diseases. Most healthy individuals, with their immune systems in good shape, are able to regularly fight off pathogens. However, pathogenic molds are dangerous to people who have compromised or weakened immune systems, which is why pathogenic molds are considered an opportunistic pathogen. Pathogenic molds most commonly affect infants, the elderly and people with suppressed immune systems.
  • Toxic molds produce mycotoxins, poisonous chemicals that are dangerous to humans. Unlike allergenic and pathogenic molds, toxic molds intentionally harm other living things rather than the harm merely being a side effect. Some of the most deadly chemicals on the planet are mycotoxins. Theyre found both on mold and on mold spores. People can get exposed to mycotoxins via ingestion, dermal exposure and inhalation. This can lead to temporary irritation or even long-term illness depending on the individual.

Because of the nature of mold, it can be harder to spot at the beginning and is something that tends to grow over time if not taken care of at the earliest.

    Generally, mold is known to grow in damp and dark places, and in areas with lower temperatures as compared to the rest of your home. Mold can occur in any part of your home, or even in your general home appliances if not tended to appropriately.

    One of the more common places that serve as a spawning ground for mold is air conditioners, particularly, the vents and ducts that help the airflow to different parts of a home. Because of the nature of air conditioners, it is incredibly easy for mold to grow rapidly, becoming rather hard for the homeowner to deal with themselves. Air conditioners tend to have a high amount of moisture and generally remain damp on a regular basis.

    Types Of Mold Colors Commonly Found In The House

    by Lisa | Apr 17, 2020 | Mold |

    Molds come in all shapes, sizes, and colors, and while some may think that color can serve as an identifying characteristic, unfortunately, it is not. The main means of identifying molds involve looking closely at the structure, spore, and growth morphology, which isnt easily done without access to a lab. Color isnt a good distinguishing characteristic of mold or toxicity because one patch can have multiple colors or change color for several reasons. Some factors that affect mold color are:

    • Food source
    • Humidity level
    • Light exposure

    Regardless of what color a mold is, if its in your house, thats a sign that there is an active moisture problem and it should be removed as soon as possible so the moisture problem can be fixed. Heres a guide to mold colors that you might find in your home.

    What Causes Mold In Homes

    Common Types Of Mold Found In Homes | Real Estate

    Mold spores may enter a home through windows or open doors, and can be brought into the home after attaching to people and pets. In order for a mold spore to grow there must be abundant moisture, the correct temperature range, and a food source.

    Moisture can come from a variety of sources. Many modern homes and buildings are constructed in a very air-tight manner. While this is great for insulation purposes, it reduces the building’s ability to “breathe” — lessening the potential drying effects of natural air circulation.

    Moisture may enter a building as a result of flooding, through broken pipes, or as a result of excessive rain. Moisture in a home or building may soak carpeting and other materials, creating a moist food source on which mold may attach and grow.

    Moisture may also enter a building through walls and living spaces by way of leaks in the roof, walls, or windows. Such leaks may be a result of poor construction, faulty design, or faulty building materials.

    Regardless of the source of moisture, once water enters the a building, mold will be drawn to it — feeding on ceiling tiles, carpet, insulation, paper backing materials, and drywall.

    Any Mold Can Be Dangerous

    The pigmentation in molds and their toxicity are not in any way connected. There are a number of molds that happen to be black or dark green in color, resembling Stachybotrys, but do not contain any of the toxins that make black mold so dangerous.

    It is fundamentally impossible to look at a mold and determine if its dangerous or not. Thats why its important to contact a professional when you discover mold. This holds true in the reverse scenario as well just because a mold isnt black, doesnt indicate that it is safe or non-toxic. Ultimately, while some molds may not be toxic or poisonous, they still indicate a problem and should be properly handled by an expert.

    Dont attempt to remove them unless youre 100% sure theyre safe and youre wearing protective equipment. Its always better to contact a professional who can attack mold at its source by repairing cracked foundations or other sources of moisture.

    How Does Mold Get In Your Home

    Excess moisture in your home is the ideal condition for mold to grow. If you are living in an area that experiences damp, wet and sometimes humid conditions then mold is more likely to grow in your home.

    Moreover, they reproduce very fast by means of small spores that travel easily through the air. You can easily spot them on your walls, appliances, floors, carpets and even on your clothes.
