Mold Damage Level 4: 100 Square Feet or More Level 4 contamination (over 100 sq. ft.) poses serious health and safety risks and requires professional remediation.

When mold growth contamination measures greater than 100 ft2 or when intense or long term exposure to mold is expected must be used?

Full Containment
Lesson 3 – Full Containment Full containment is recommended for the clean up of mold-contaminated surface areas of more than 100 square feet and when intense or long-term exposures are expected.

What are acceptable mold levels?

What is Considered A Normal Mold Count? A normal mold spore count in a room is typically 200-500 spores. Anywhere between 1-1500 mold spores in a room is normal and safe as long as mold colonies are not visibly growing and no water damage is present. Mold spores are present in virtually every room of every building.

What does it mean to have mold in your lungs?

The mold spores can colonize (grow) inside lung cavities that developed as a result of chronic diseases, such tuberculosis, emphysema, or advanced sarcoidosis. The fibers of fungus might form a lump by combining with white blood cells and blood clots. This lump or ball of fungus is called an aspergilloma or mycetoma.

What is considered high mold count?

100 cfu or less per cubic meter of air indicates low risk. 100 cfu to 1000 cfu per cubic meter of air indicates intermediate risk. 1000 or more cfu per cubic meter of air indicates a high risk.

What is a high count of Aspergillus?

200-500 spores – the most common species (Penicillium/Aspergillus, Cladosporium and Curvularia) are typically not an issue and stay within the normal range. 500-1500 spores – sometimes the Penicillium/Aspergillus & Cladosporium levels are in this range and do not require remediation.

What kind of respirator is good for mold?

If there is mold in your home (or you suspect that mold growth has occurred), protect your mouth and nose against breathing in mold by wearing at least a disposable, NIOSH-approved N-95 filtering facepiece respirator (often called an “N-95 respirator” or “N-95 mask”).

What happens when you clean mold without a mask?

If you’re not wearing any Personal Protective Equipment (PPE), you’re inviting all of those mold spores to settle on your clothing, the area you’re cleaning, your shoes (allowing mold to travel to other areas in your home), in your eyes, and up your nose into your upper respiratory system.

What mold count is considered high?

Mold produces spores that move, like pollen, in outdoor air during warmer months. 1 to 6,499 is a low spore count. 6,500 to 12,999 is a moderate spore count. 13,000 to 49,999 is a high spore count.

What is a bad mold count?

50-200 spores – still very low levels; the toxic mold species Stachybotrys and Memnoniella are some of the species to be considered an issue at this level. 200-500 spores – the most common species (Penicillium/Aspergillus, Cladosporium and Curvularia) are typically not an issue and stay within the normal range.

How do I choose the level of containment for mold?

Although, in general, the size of the contaminated area indicates the level of containment required, the final choice of containment level should be based on professional judgment. Heavy mold growth in a small area, for example, could release more mold spores than lighter growth in a relatively large area.

How does mold affect the structural integrity of a building?

Problems may arise when mold starts eating away at materials, affecting the look, smell, and possibly, with the respect to wood-framed buildings, affecting the structural integrity of the buildings. Molds can grow on virtually any substance, as long as moisture or water, oxygen, and an organic source are present.

What are the health risks of mold exposure?

There are many types of mold. Most typical indoor air exposures to mold do not present a risk of adverse health effects. Molds can cause adverse effects by producing allergens (substances that can cause allergic reactions). Potential health concerns are important reasons to prevent mold growth and to remediate existing problem areas.

Are there federal standards for airborne levels of mold?

Currently, there are no federal standards or recommendations, (e.g., OSHA, NIOSH, EPA) for airborne concentrations of mold or mold spores. Scientific research on the relationship between mold exposures and health effects is ongoing.
