Mold Remediation >> EPA Contractors Mold Requirements

In order to limit your exposure to airborne mold, you may want to wear an N-95 respirator, available at many hardware stores and from companies that advertise on the Internet. (They cost about $12 to $25.) Some N-95 respirators resemble a paper dust mask with a nozzle on the front, others are made primarily of plastic or rubber and have removable cartridges that trap most EPA Contractors Mold Requirements of the mold spores from entering. 

In order to be effective, the respirator or mask must fit properly, so carefully follow the instructions supplied with the respirator. Please note that the Occupational Safety and Health Administration (OSHA) requires that respirators fit properly (fit testing) when used in an occupational setting; EPA Contractors Mold Requirements consult OSHA for more information (800-321-OSHA orwww.osha.gov). 

Wear gloves. Long gloves that extend to the middle of the forearm are recommended. When working with water EPA Contractors Mold Requirements and a mild detergent, ordinary household rubber gloves may be used. If you are using a disinfectant, a biocide such as chlorine bleach, or a strong cleaning solution, you should select gloves made from natural rubber, neoprene, nitrile, polyurethane, or PVC (see Cleanup and Biocides). 

Avoid touching mold or moldy items with your bare hands.Wear goggles. Goggles that do not have ventilation holes are recommended. Avoid getting mold or mold spores in your eyes. How Do I Know When the Remediation or Cleanup is Finished? Mold growing on a suitcase stored in a EPA Contractors Mold Requirements humid basement.

You must have completely fixed the water or moisture problem before the cleanup EPA Contractors Mold Requirements or remediation can be considered finished. You should have completed mold removal. Visible mold and moldy odors should not be present. Please note that mold may cause staining and cosmetic damage. You should have revisited the site(s) shortly after cleanup and it should show no signs of water damage or mold growth. 

People should have been able to occupy or re-occupy the area without health complaints or physical symptoms. Ultimately, EPA Contractors Mold Requirements this is a judgment call; there is no easy answer. If you have concerns or questions consult ourFrequently Asked Questions database and ask a question if you don't find what you need.

Moisture and Mold Prevention EPA Contractors Mold Requirements and Control Tips Moisture Control is the Key to Mold Control Mold growing on the surface of a unit ventilator.Click on the image for a larger version. Condensation on the inside of a windowpane. When water leaks or spills occur indoors -ACT QUICKLY. If wet or damp materials or areas are dried 24-48 hours after a leak or spill happens, in most cases mold will not grow. 

Clean and repair roof gutters regularly. Make sure the ground slopes away from the building foundation, so that water does not enter EPA Contractors Mold Requirements or collect around the foundation. Keep air conditioning drip pans clean and the drain lines unobstructed and flowing properly. Keep indoor humidity low. If possible, keep indoor humidity below 60 percent (ideally between 30 and 50 percent) relative humidity. 

Relative humidity can be measured with a moisture or humidity meter, a small, inexpensive ($10-$50) instrument available at many hardware stores. If you see condensation or moisture collecting on windows, walls or pipes ACT QUICKLY to dry the wet surface EPA Contractors Mold Requirements and reduce the moisture/water source. Condensation can be a sign of high humidity.Actions that will help to reduce humidity 

Vent appliances that produce moisture, such as clothes dryers, stoves, and kerosene heaters to the outside where possible. (Combustion appliances such as stoves EPA Contractors Mold Requirements and kerosene heaters produce water vapor and will increase the humidity unless vented to the outside.) Use air conditioners and/or de-humidifiers when needed. 

Run the bathroom fan EPA Contractors Mold Requirements or open the window when showering. Use exhaust fans or open windows whenever cooking, running the dishwasher or dishwashing, etc.Actions that will help prevent condensation‚ Mold growing on a wooden headboard in a room with high humidity.Click on the image for a larger version. 

Reduce the humidity. Increase ventilation or air movement by opening doors and/or windows, when practical. Use fans as needed. Cover cold surfaces, such as cold water pipes, EPA Contractors Mold Requirements with insulation. Increase air temperature. Renters: Report all plumbing leaks and moisture problems immediately to your building owner, manager, or superintendent. In cases where persistent water problems are not addressed.

You may want to contact local, state, or federal health or housing authorities. You can also contact your state health department.Testing or EPA Contractors Mold Requirements Sampling for Mold Rust is an indicator that condensation occurs on this drainpipe. The pipe should be insulated to prevent condensation.Click on the image for a larger version.

Is sampling for mold needed? In most cases, if visible mold growth is present, sampling is unnecessary.Since no EPA or other federal limits have been set for mold or mold spores, EPA Contractors Mold Requirements sampling cannot be used to check a building's compliance with federal mold standards. Surface sampling may be useful to determine if an area has been adequately cleaned or remediated. 

Sampling for mold should be conducted by professionals who have specific experience in designing mold sampling protocols, EPA Contractors Mold Requirements sampling methods, and interpreting results. Sample analysis should follow analytical methods recommended by the American Industrial Hygiene Association (AIHA), the American Conference of Governmental Industrial Hygienists (ACGIH), or other professional organizations.

Hidden Mold Suspicion of hidden mold You may suspect hidden mold if a building smells moldy, but you cannot see the source, or if you know there has been water damage and EPA Contractors Mold Requirements residents are reporting health problems. Mold may be hidden in places such as the back side of dry wall, wallpaper, or paneling, the top side of ceiling tiles, the underside of carpets and pads, etc. 

Other possible locations of hidden mold include areas inside walls around pipes (with leaking or condensing pipes), EPA Contractors Mold Requirements the surface of walls behind furniture (where condensation forms), inside ductwork, and in roof materials above ceiling tiles (due to roof leaks or insufficient insulation).Investigating hidden mold problems 

Investigating hidden mold problems may be difficult and will require caution when the investigation involves disturbing potential sites of mold growth. For example, removal of wallpaper can lead to a massive release of spores if there is mold growing on the underside of the paper. If you believe that you may have a hidden mold problem, EPA Contractors Mold Requirements consider hiring an experienced professional.

Cleanup and Biocides Biocides are substances that can destroy living organisms. The use of a chemical or biocide that kills organisms such as mold (chlorine bleach, for example) is not recommended as a routine practice during mold cleanup. There may be instances, EPA Contractors Mold Requirements however, when 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; EPA Contractors Mold Requirements a background level of mold spores will remain - these spores will not grow if the moisture problem has been resolved. If you choose to use disinfectants or biocides, always ventilate the area and exhaust the air to the outdoors. Never mix chlorine bleach solution with other cleaning solutions or detergents that contain ammonia because toxic fumes could be produced.
