Mold Remediation >> Mold Tester Certification

There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system. There are several important points to understand concerning mold detection in heating and cooling systems: Many sections of your heating and cooling system may not be accessible for a visible inspection, Mold Tester Certification so ask the service provider to show you any mold they say exists. 

You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and Mold Tester Certification may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it. 

If you have insulated air ducts and the insulation gets wet or moldy it cannot be effectively cleaned and should be removed Mold Tester Certification and replaced. If the conditions causing the mold growth in the first place are not corrected, mold growth will recur.

Molds on Foods: Are They Dangerous? September 2005 A Brief Guide to Mold in the Workplace, U.S. Dept. of Labor, Occupational, Safety and Health Administration, Mold Tester Certification Safety and Health Bulletin 03-10-10Indoor Air Regulations and Mold Standards or Threshold Limit Values (TLVs) for airborne concentrations of mold, or mold spores, have not been set. 

Currently, there are no EPA regulations or standards for airborne mold contaminants. Large Buildings and Mold EPA has a number of resources available, Mold Tester Certification you can start with the Indoor Air Quality Building Evaluation and Assessment Model (I-BEAM). I-BEAM updates and expands EPA's existing Building Air Quality guidance and is designed to be comprehensive state-of-the-art guidance for managing IAQ in commercial buildings. 

This guidance was designed to be used by building professionals Mold Tester Certification and others interested in indoor air quality in commercial buildings. I-BEAM contains text, animation/visual, and interactive/calculation components that can be used to perform a number of diverse tasks. See www.epa.gov/iaq/largebldgs/i-beam/index.html.

Mold and mildew are commonly found on the exterior wall surfaces Mold Tester Certification of corner rooms in heating climate locations. 

An exposed corner room is likely to be significantly colder than adjoining rooms, Mold Tester Certification so that it has a higher relative humidity (RH) than other rooms at the same water vapor pressure. If mold and mildew growth are found in a corner room, then relative humidity next to the room surfaces is above 70%. However, is the RH above 70% at the surfaces because the room is too cold or because there is too much moisture present (high water vapor pressure)?

The amount of moisture in the room can be estimated by measuring both temperature and RH at the same location and at the same time. Suppose there are two cases. In the first case, Mold Tester Certification assume that the RH is 30% and the temperature is 70 F in the middle of the room. The low RH at that temperature indicates that the water vapor pressure (or absolute humidity) is low. 

The high surface RH is probably due to room surfaces that are "too cold." Temperature is the dominating factor, Mold Tester Certification and control strategies should involve increasing the temperature at cold room surfaces.In the second case, assume that the RH is 50% and the temperature is 70oF in the middle of the room. The higher RH at that temperature indicates that the water vapor pressure is high and there is a relatively large amount of moisture in the air. 

The high surface RH is probably due to air that is "too moist." Humidity is the dominating factor, Mold Tester Certification and control strategies should involve decreasing the moisture content of the indoor air. Schools and Mold and Indoor Air Quality The Agency's premier resource on this issue is the Indoor Air Quality Tools for Schools kit. 

Our schools-related resources on the web start. The asthma companion piece for the IAQ Tools for Schools Action kit, Mold Tester Certification is Managing Asthma in the School Environment -www.epa.gov/iaq/schools/managingasthma.html. This publication has a section entitled Clean Up Mold and Moisture Control: An excerpt follows: Common Moisture Sources Found in Schools 

Moisture problems in school buildings can be caused by a variety of conditions, including roof Mold Tester Certification and plumbing leaks, condensation, and excess humidity. Some moisture problems in schools have been linked to changes in building construction practices during the past twenty to thirty years. These changes have resulted in more tightly sealed buildings that may not allow moisture to escape easily. 

Moisture problems in schools are also associated with delayed maintenance or insufficient maintenance, due to budget and other constraints. Temporary structures in schools, such as trailers Mold Tester Certification and portable classrooms, have frequently been associated with moisture and mold problems.Suggestions for Reducing Mold Growth in Schools 

Reduce Indoor Humidity Vent showers Mold Tester Certification and other moisture-generating sources to the outside. Control humidity levels and dampness by using air conditioners and de-humidifiers. Provide adequate ventilation to maintain indoor humidity levels between 30-60%. Use exhaust fans whenever cooking, dishwashing, and cleaning in food service areas.

Inspect the building for signs of mold, moisture, leaks, Mold Tester Certification or spills Check for moldy odors. Look for water stains or discoloration on the ceiling, walls, floors, and window sills. Look around and under sinks for standing water, water stains, or mold. Inspect bathrooms for standing water, water stains, or mold. 

Do not let water stand in air conditioning or refrigerator drip pans.Respond promptly when you see signs of moisture and/or mold, or Mold Tester Certification when leaks or spills occur Clean and dry any damp or wet building materials and furnishings within 24-48 hours of occurrence to prevent mold growth. Fix the source of the water problem or leak to prevent mold growth. 

Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, Mold Tester Certification that are moldy, may need to be replaced. Check the mechanical room and roof for unsanitary conditions, leaks, or spills. Prevent moisture condensation Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors) by adding insulation.

Floor and carpet cleaning Remove spots and stains immediately, using the flooring manufacturer’s recommended techniques. Use care to prevent excess moisture or cleaning residue accumulation and ensure that cleaned areas are dried quickly. In areas where there is a perpetual moisture problem, do not install carpeting (i.e., by drinking fountains, by classroom sinks, Mold Tester Certification or on concrete floors with leaks or frequent condensation).
