Mold Remediation: Level 1-small isolated area (10 square feet or less)
At this level you can take care of the mold contamination on your own hence saving you the money that you could have spent on a mold remediation company. This level categorizes small infections that are usually found on ceilings and small areas on the wall. Mold remediation can be conducted by regular building maintenance but those doing this job should remember to wear personal protective garments such as glove, disposable respirator and eye protection. The work area and the adjacent spaces should be unoccupied. Containment can be done by simply misting the contaminated area prior to remediation. After cleaning the area with a damp cloth and removing materials that cannot be cleaned from the house, you should let it dry completely to prevent further mold growth.
Level 2- mid size isolated areas (10-30 square feet)
The same protective measures in level 1 should be also taken when dealing with mold remediation in this level. After taking out all the materials that have mold in plastic bags that are tightly sealed you should and the mold contaminated area is thoroughly cleaned with a damp cloth the area should be vacuumed with a HEPA vacuum.
Level 3- large isolated areas (30- 100 square feet)
At this level mold contaminates patches on the wall the same precautions applied in level 1 and level 2 should also be applied in level 3. In addition to these precautions, use plastic sheets to seal all the air movements around the work area and places adjacent to it. Vacate all the occupants in the work area as well as the surroundings. All areas should be completely dry and visibly free from mold.
Level 4- Extensive contamination (more than 100 square feet)
At this level health and safety professionals who are trained in mold investigations (mold remediation) should be consulted before the mold remediation process begins. Every a person that will be working in the infested area should put on protective garments that are disposable to prevent mold spore from spreading to other parts of the house. Working area should also be completely isolated from the rest of the home. All the openings should be completely since mold is air borne. Before reoccupying the make sure that air monitoring is conducted to confirm if your home is safe for you to move back in.
Level 5- (Air Conditioner and HVAC Systems)
If only a small part of the air condition is infested by mold then you can handle this problem using the steps in levels 1 and 2. However it is recommended that all mold infestation in air conditioners and HVAC systems should be left to the professional mold remediation companies who should follow the precaution measures in levels 1 through to level 4. In addition to these, the workers should shut down the HVAC system before commencing with the work and remove any material that is supporting the growth of the mold in the system and seal it in a plastic bag. They should also use antimicrobial agents that are designed to prevent the growth of the mold.
