Containment Is Critical When Dealing With Black Mold Cleanup

Using containment to clean up toxic black mold is beneficial. The goal is to prevent dust, mold and moisture from circulating throughout the home or building, and limit spreading to unaffected areas. The bigger the area, the greater the chances, someone will be exposed to mold. Stop it in its tracks before health concerns become an issue

Containment limits the release of toxic black mold into the environment. In an effort to prevent exposure, mold and moldy material prevention from entering outside of contaminated areas is crucial. Sometimes the size of the space can assist in determining how much clean up is required; however, this isn’t a hard-and-fast rule. Smaller spaces may have a heavier growth than larger. Therefore, professional judgment is necessary in each case.

Determining square footage in the space will help figure out what type of containment is necessary. Limited containment is recommended for between 10 and 100 square ft of mold contamination. A single layer of fire-retardant polyethylene should surround the moldy area. Use duct tape to adhere the polyethylene to floors and ceilings. Seal all doors, air vents, risers, and pipe chases within the area to reduce movement to other parts of the building or home.

If it is used as return air, the HVAC may be impacted by heavy mold growth. When this happens, containment should be installed from floor to ceiling and filters immediately replaced. To ensure contaminated air does not seep into surrounding areas, maintain negative pressure, and use an exhaust fan ducted to the outside.

Full containment covers surfaces 100 ft or more. In this case, layers of double polyethylene are used to protect the moldy area and other parts of the building/home. Create a slit entryway to the airlock from the outside. Utilize for entry and exit to the area; see that it is large enough to hold a waste container because all contaminated items must be sealed while in the chamber.

Personal protective equipment is essential when cleaning a contaminated surface
. Gloves, goggles, air purifying respirators, and disposable clothing need to be worn at all times. For full containment or in situations of high-level air-born mold spores, full PPE is necessary. This includes full-faced powered air purifiers where a hood or full-face mask prevents unfiltered air from entering.

Containment is an effective way to remove mold toxins. Remember to use care when attempting it. If inexperienced, a trusted professional can get the job done fast and efficiently.
