Mold Remediation >> Cleaning Mold

Large areas of mold contamination (greater than 30 square feet) require more extensive investigation and usually should be done by professionals with training and experience in remediating contaminated buildings. As the area of contamination becomes greater the need for adequate containment increases. This often requires more sophisticated barriers, entry chambers and Cleaning Mold maintenance of decreased air pressure in the work area or increased air pressure in surrounding areas. 

There are, however, Cleaning Mold a few special situations in which a builder’s own workers can safely remediate an area of mold contamination that exceeds 30 square feet. These are areas easily isolated from the rest of the building and that have separate means of egress (doors or windows). Crawl spaces, attics and building additions or wings are examples of this type.  

Seal openings between the work area and the rest of the home. If air ducts are located in the contaminated are, Cleaning Mold they should be sealed to protect them during the remediation. It is possible that the air ducts are already contaminated so they should be inspected as part of the remediation process. Evacuate the areas of the home adjoining the work area so that if containment is lost unprotected individuals will not be exposed. 

Better still, Cleaning Mold evacuate the home during the clean up. This issue needs to be addressed on a case by case basis before the work begins. Maintain a lower air pressure in the work area than in the adjoining areas by using a HEPA machine or a fan exhausted to the outside with HEPA filtration. Alternatively, maintain a higher air pressure in the surrounding areas using a fan door (blower door).  

Personal protective equipment: gloves, eye protection without vents, Cleaning Mold disposable protective clothing that also covers the head and feet and at a minimum a N95 respirator. Consider use of full-face mask respirators with HEPA filtration canisters. The remainder of the clean-up is similar to that for smaller areas. 

In many instances where mold is found in exterior walls much of the Cleaning Mold work can be done from the outside. Houses with easy to remove cladding such as vinyl siding are ideally suited for this approach. The entire home can be pressurized when the work is being done from the outside. A plastic sheet taped to the interior of the exterior wall can be used to provide the containment barrier. 

Large areas inside of homes (not within exterior walls) - (more than 100 square feet of mold damaged material) require individuals with training and experience in Cleaning Mold remediating extensively contaminated buildings. See the New York City Guidelines below. The New York City Department of Health’s Guidelines for Mold Remediation Introduction 

Although our recommendations are directed to specific locations or types of mold problems, we will briefly discuss the New York City Guidelines. Level I - small isolated areas: less than 10 square feet, e.g. Ceiling tiles, Cleaning Mold small areas on walls Can be performed by regular maintenance staff. Personal protective equipment: N95 disposable respirator, gloves and eye protection.  

The work area should be unoccupied. Containment of the work area is not necessary. Suppress dust production by misting surfaces prior to removing. Contaminated materials that are removed should be sealed in plastic bags. Scrub contaminated materials with soap and water; Cleaning Mold rinse thoroughly and allow to dry.  

HEPA vacuum the work area so that it is free of dust. Level II - mid-sized isolated areas: 10-30 square feet May be performed by regular maintenance staff. Personal protective equipment: N95 disposable respirator, gloves Cleaning Mold and eye protection. The work area should be unoccupied. The work area should be isolated from the rest of the building using polyethylene sheeting that is sealed with tape.  

Contaminated materials that are removed should be sealed in plastic bags. Scrub contaminated materials with soap Cleaning Mold and water; rinse thoroughly; and allow to dry. The work area and the access areas should be HEPA vacuumed and cleaned with disposable damp cloths. Level III - large isolated areas : 30-100 square feet.  

Consult a health and safety professional with experience performing microbial investigations. Work should be done by individuals trained in handling hazardous materials. Personal protective equipment: N95 disposable respirator, gloves Cleaning Mold and eye protection. The work area should be unoccupied. The work area should be isolated from the rest of the building using polyethylene sheeting that is sealed with tape.  

Contaminated materials that are removed should be sealed in plastic bags. Scrub contaminated materials with soap and water; Cleaning Mold rinse thoroughly; and allow to dry. The work area and the access areas should be HEPA vacuumed and cleaned with disposable damp cloths. Level IV – extensive contamination: greater than 100 square feet in one area.  

Consult a health and safety professional with experience performing microbial investigations. Work should be done by individuals trained in handling hazardous materials. Personal protective equipment: full-face respirator with HEPA cartridges, gloves Cleaning Mold and disposable protective clothing covering that also covers head and shoes.  

The Cleaning Mold work area should be unoccupied. The work area should be isolated from the rest of the building using polyethylene sheeting that is sealed with tape. Use an exhaust fan with a HEPA filter to generate negative pressure in the work (containment area). Use air locks Contaminated materials that are removed should be sealed in plastic bags.  

Scrub contaminated materials with soap and water; rinse thoroughly; and allow to dry. The work area Cleaning Mold and the access areas should be HEPA vacuumed and cleaned with disposable damp cloths.
