• What To Wear When Cleaning Moldy Areas

It is important to take precautions to Limit Your Exposure to mold and mold spores.

  • Avoid breathing in mold or mold spores. 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 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; consult OSHA for more information (800-321-OSHA or osha.gov/).

  • Wear gloves. Long gloves that extend to the middle of the forearm are recommended. When working with water 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 section). 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?
  • You must have completely fixed the water or moisture problem before the cleanup 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, this is a judgment call; there is no easy answer. If you have concerns or questions call the EPA Indoor Air Quality Information Clearinghouse at (800) 438-4318.


  • Moisture and Mold Prevention and Control Tips

Moisture control is the KEY to mold control. 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 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 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 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 or open the window when showering. Use exhaust fans or open windows whenever cooking, running the dishwasher or dishwashing, etc.

Thank you for posting on our forum.
We don't have training that specifically enables you to get a mold inspection certification. You would need to go to a school/organization that can give a certification.

Our Nemmar.com training is for people to self-teach themselves what they need to know about real estate - from Asbestos to Zoning. So you can read through our site content in the real estate library and you will find a ton of helpful advice and information. We are adding new content weekly to the site so please return often to see the updates and new information.
