Mold Remediation >> Mold Inspection

Health Concerns If building occupants are reporting serious health concerns, you should consult a health professional. In cases in which a particularly toxic mold species has been identified or is suspected, when extensive hidden mold is expected (such as behind vinyl wallpaper or in the HVAC system), when the chances of the mold becoming airborne are estimated to be high, or sensitive individuals (e.g., those with severe allergies or asthma) are present, a more cautious Mold Inspection or conservative approach to remediation is indicated. 

Always make sure to protect remediators and building occupants from exposure to mold. Cleanup Methods Molds Can Damage Building Materials Mold Inspection and Furnishings mold can eventually cause structural damage to a school or large building, if a mold/moisture problem remains unaddressed for a long time. 

In the case of a long-term roof leak, for example, molds can weaken floors and walls as the mold feed on wet wood. If you suspect that mold has damaged building integrity, Mold Inspection you should consult a structural engineer or other professional with expertise in this area. A variety of mold cleanup methods are available for remediating damage to building materials and furnishings caused by moisture control problems and mold growth. 

The specific method or group of methods used will depend on the type of material affected, as presented in Table 2. Please note that professional remediators may use some methods not covered in these guidelines; Mold Inspection absence of a method in the guidelines does not necessarily mean that it is not useful. Method 1: Wet Vacuum Wet vacuums are vacuum cleaners designed to collect water. 

They can be used to remove water from floors, carpets, and hard surfaces where water has accumulated. They should not be used Mold Inspection to vacuum porous materials, such as gypsum board. They should be used only when materials are still wet — wet vacuums may spread spores if sufficient liquid is not present. 

The tanks, hoses, and attachments of these vacuums should be thoroughly cleaned and dried after use since mold and mold spores may stick to the surfaces. Method 2: Damp Wipe Whether dead or alive, Mold Inspection mold is allergenic, and some molds may be toxic. mold can generally be removed from nonporous (hard) surfaces by wiping or scrubbing with water, or water and detergent. 

It is important to dry these surfaces quickly and thoroughly to discourage further mold growth. Instructions for cleaning surfaces, as listed on product labels, Mold Inspection should always be read and followed. Porous materials that are wet and have mold growing on them may have to be discarded. Since molds will infiltrate porous substances and grow on or fill in empty spaces or crevices, the mold can be difficult or impossible to remove completely. 

Method 3: HEPA Vacuum mold and Paint Don't paint or caulk moldy surfaces; clean Mold Inspection and dry surfaces before painting. Paint applied over moldy surfaces is likely to peel. HEPA (High-Efficiency Particulate Air) vacuums are recommended for final cleanup of remediation areas after materials have been thoroughly dried and contaminated materials removed. 

HEPA vacuums are also recommended for Mold Inspection cleanup of dust that may have settled on surfaces outside the remediation area. Care must be taken to assure that the filter is properly seated in the vacuum so that all the air must pass through the filter. When changing the vacuum filter, remediators should wear PPE to prevent exposure to the mold that has been captured. 

The filter and contents of the HEPA vacuum must be disposed of in well-sealed plastic bags. mold Remediation/Cleanup and Biocides The purpose of mold remediation is to remove the mold to prevent human exposure and damage to building materials Mold Inspection and furnishings. It is necessary to clean up mold contamination, not just to kill the mold. 

Dead mold is still allergenic, and some dead molds are potentially toxic. The use of a biocide, such as chlorine bleach, is not recommended as a routine practice during mold remediation, Mold Inspection although there may be instances where professional judgment may indicate its use (for example, when immune-compromised individuals are present). 

In most cases, it is not possible or desirable to sterilize an area; Mold Inspection a background level of mold spores will remain in the air (roughly equivalent to or lower than the level in outside air). These spores will not grow if the moisture problem in the building has been resolved. If you choose to use disinfectants or biocides, always ventilate the area. 

Outdoor air may need to be brought in with fans. When using fans, take care not to distribute mold spores throughout an unaffected area. Biocides are toxic to humans, Mold Inspection as well as to mold. You should also use appropriate PPE and read and follow label precautions. Never mix chlorine bleach solution with cleaning solutions or detergents that contain ammonia; toxic fumes could be produced. 

Some biocides are considered pesticides, and some States require that only registered pesticide applicators apply these products in schools. Make sure anyone applying a biocide is properly licensed, Mold Inspection if necessary. Fungicides are commonly applied to outdoor plants, soil, and grains as a dust or spray — examples include hexachlorobenzene, organomercurials, pentachlorophenol, phthalimides, and dithiocarbamates. 

Do not use fungicides developed for use outdoors for mold remediation or for any Mold Inspection other indoor situation. Method 4: Discard — Remove Damaged Materials and Seal in Plastic Bags Building materials and furnishings that are contaminated with mold growth and are not salvageable should be double-bagged using 6-mil polyethylene sheeting. 

These materials can then usually be discarded as ordinary construction waste. It is important to package mold-contaminated materials in sealed bags before removal from Mold Inspection the containment area to minimize the dispersion of mold spores throughout the building. Large items that have heavy mold growth should be covered with polyethylene sheeting and sealed with duct tape before they are removed from the containment area. 

Personal Protective Equipment (PPE) Always use gloves Mold Inspection and eye protection when cleaning up mold! If the remediation job disturbs mold and mold spores become airborne, then the risk of respiratory exposure goes up. Actions that are likely to stir up mold include: breakup of mold porous materials such as wallboard; invasive procedures used to examine or remediate mold growth in a wall cavity.

Actively stripping or peeling wallpaper to remove it; Mold Inspection and using fans to dry items. The primary function of Personal Protective Equipment (PPE) is to avoid inhaling mold and mold spores and to avoid mold contact with the skin or eyes. The following sections discuss the different types of PPE that can be used during remediation activities. 

Please note that all individuals using certain PPE equipment, such as half-face or full-face respirators, must be trained, must have medical clearance, and must be fit-tested by a trained professional. In addition, Mold Inspection the use of respirators must follow a complete respiratory protection program as specified by the Occupational Safety and Health Administration.
