Different Types of Mold and How to Get Rid of Them
Before you call in a professional for mold removal, you should know the types of mold that you are dealing with. There are different kinds of mold, including Stachybotrys and Aureobasidium. Learn about the differences and what each one means to your property. Read about Pre-testing for mold, Methods of removal, and Containment chambers. Listed below are some of the most common types of mold.
Containment chambers are a must-have for any home or business with a serious mold problem. These containment chambers come in many different sizes, from small, portable units to large, fully operational units. To avoid bringing contaminated air into the containment chamber, make sure the area you plan to contain has adequate space for work. Once you’ve decided on the size of the containment chamber, make sure to purchase a negative air machine with a HEPA filter.
Containment chambers have several benefits. Unlike traditional containment, these chambers allow the mold removal contractor to seal off a small area from the rest of the building. They can be placed across doorways or around the contaminated area. A heavy plastic wall helps prevent mold spores from escaping through the walls, but the mold abatement technician can still access the area. This method of mold containment can help minimize exposure to mold spores and dust, and protect the building’s occupants and the staff.
The primary function of containment chambers during mold abatement is to prevent the transfer of contaminated materials from the building to the outside. Containments can also act as a barrier to keep contaminants from escaping the containment during remediation. They can also be left in place during the reconstruction process. Ultimately, containment chambers are a great investment for a home or business with a mold problem.
One of the most common mold-infested areas can be encapsulated by a single layer of six-mil fire-resistant polyethylene sheeting. To prevent mold spores from spreading throughout the building, it is important to carefully package all materials in this manner. Additionally, large items that are affected by heavy mold growth should be covered with polyethylene sheeting and secured with duct tape. Protect your eyes and hands from mold spores by wearing gloves and eye protection while cleaning.
When choosing a containment chamber for mold abatement, keep in mind that the relative humidity of the enclosed area can be as high as 60%. High humidity levels can be easily reached in a remediation process. If the indoor environment is too humid, HVAC systems can be shut down, and portable HVAC systems can be added to the containment chamber. Regardless of the method, a containment chamber must contain the mold in order to protect the rest of the building and property from further contamination.
There are two main types of containment systems: limited and full. For small-to-medium-sized mold infestations, limited containment is enough to isolate the area. A 6-mil polyethylene sheeting barrier separates the mold abatement work area from other parts of the building or occupied spaces. This double barrier may also include an access panel for exhausting air scrubbers. The barrier may be removed after the cleanup process is complete or before the building is cleared.
Once containment is achieved, the moldy materials must be removed from the area. Moldy materials should be double-bagged or removed as construction waste. When these materials are removed, a HEPA-filtered negative air machine will remove them from the building. This process will minimize the spread of mold spores throughout the building. Large items that have heavy mold growth should be covered with polyethylene sheeting and sealed with duct tape. To protect workers and the building, wearing eye and face protection is vital.
To complete full containment, you must install a barrier that blocks the air ingress. The containment barrier must be installed in an area with an open path. To seal off the area, all cabinetry and openings should be covered. To complete the barrier, attach six-mil polyurethane film to the ceiling and walls. Heavy-duty tape may be required to keep the barriers in place. Once the barrier has been installed, seal all doors and windows.
The proper containment for mold abatement can greatly reduce the extent of work, but can also protect workers from further contamination. Mold spores settle throughout the home, and this can make the job more expensive than it is worth. Proper containment includes a protective barrier, such as plastic sheeting or HEPA scrubbers, and negative air machines. This technique is similar to that used during asbestos abatement.
In addition to constructing a full containment barrier, it is also important to protect occupants from mold spores. Full containment should consist of two layers of fire-resistant polyethylene sheeting and one airlock chamber. An HEPA-filtered fan should be used to maintain negative pressure in the area. The supply and return air vents should also be blocked. Below are some tips for creating a safe containment for mold abatement.
Pre-testing for mold
While mold abatement companies may recommend pre-testing for potential contaminants, it’s not always necessary. Most mold professionals can identify the presence of mold and other contaminants by simply wiping a pre-moistened cotton swab on the affected area. ATP is a universal energy molecule found in all living organisms. This molecule is also present in very small quantities in microbial contamination. When the swab is placed in a special mold tester, it produces a light signal. Within seconds, the device will give a reading that confirms the presence of mold. This test is often used post-mold removal to make sure the area is free of any traces of mold.
Often, a mold test will reveal the presence of mold in the air. An indoor air quality test from an accredited laboratory can help determine whether the presence of mold is a cause for concern. Depending on the results of the indoor air quality test, additional tests may be required. For example, a mold-specific test may require closing external doors while leaving internal ones open. An RTK technician will provide detailed information about pre-testing, including what type of ventilation is needed, how to keep outside doors open, and more.
The air samples taken during pre-testing will help assess the presence of mold spores in the air. For this purpose, multiple samples are required. However, if the mold is only visible, then testing will not be required. Nevertheless, if you have a mold-free environment, you can choose a qualitative testing method instead. However, you can’t guarantee that there’s no mold, so qualitative testing is usually your best bet.
The pre-testing process is the first step in remediation, as this determines whether there is an elevated level of mold present in your home. Once the remediation process has been completed, a post-testing report will allow you to verify that the mold-free space is 100% safe. Having this report is also a good way to protect yourself and others involved in the remediation process. If you are planning to sell your property, you can use this report as a guarantee of quality work.
Methods of removal
Various types of mold are dangerous, and removing them is essential to prevent further health problems. While most mold is harmless, pathogenic and allergenic types may be harmful to the health of people exposed to them. These fungi are difficult to remove with simple home disinfecting products, but removing a large colony of pathogenic mold may require a professional. Here’s a guide to identifying the most common types.
First, make sure to remove any loose debris, such as spores and sludge. Then, you should place the wet materials into six-mil plastic bags and tie them closed. After that, you should wipe away any remnants with a damp cloth dipped in detergent solution. Finally, you can dispose of the plastic bags as regular trash. If the mold is difficult to remove, you may need to perform a dry cleaning.
Using household disinfectants is another effective method. You should always use proper ventilation when applying these products. Always wear protective gear while using household bleach. Distilled white vinegar is another good alternative to household bleach. It is acidic and breaks down the mold structure. Moreover, it’s non-toxic. If the latter method doesn’t work, you can try diluted tea tree oil. The two-tea-tea tree oil mixture is an effective method.
In most cases, a homeowner can safely remove different types of mold. Stachybotrys mold is the most common in the home, and it grows on wood, paper, and wicker. Aspergillus mold is another common type of household mold. It’s commonly found in bathrooms and is often present on air conditioning systems. The main danger associated with black mold is that it can cause various medical problems. Hence, you should remove mold as soon as you find it.
A DIY approach to removing mold is an excellent option for homeowners who have some handy skills. If you’re a handy person with an afternoon on your hands, you can handle this mold removal yourself. Just be sure to wear protective gear and a mask. A professional mold remediation service will use HEPA filters to capture spores and prevent further exposure to mold spores. If you’re unsure of your skills, it’s safer to hire a professional mold removal service.
