Los Angeles, California (PressExposure) November 29, 2012 -- To find, kill, and remove toxic mold growth inside heating, ventilating and air conditioning (HVAC) equipment and ducts, Enviro Dangers launches on December 1, 2012, the new HVAC Mold Removal Protocolâ¢ for homes, commercial buildings, and public buildings in California, Las Vegas, Arizona, and nationwide USA.
Developed by mold experts Phillip Fry and Divine Fry, the protocol includes these ten steps:
1. Mold test both the outward air flow from each HVAC air supply duct register and all rooms and areas (including crawl space, basement, and attic) with either an air pump with Air-O-Cell mold sampling cassettes or Petri lab dishes with malt agar growth nutrient.
2. Mold test one outdoor location five feet beyond the building's roof water drip edge as a control test against which to compare indoor mold lab results.
3. Have the mold tests and the outdoor control test analyzed by a certified mold laboratory for mold species identification and quantification. A property owner, manager, or tenant can specify either the nonviable analysis method for quick lab results or the viable analysis method, in which the mold samples are grown for 7 days to identify and count only living mold colonies---as contrasted with both live and dead mold spores being identified and counted in the nonviable method.
4. If one or more of the indoor mold lab test results discovers more types of mold species and/or greater mold spore or mold colony counts, or if the indoor mold counts are especially high regardless of the outdoor test comparison, do the following mold remediation steps for the HVAC equipment and systems, along with the entire home or building. Airborne mold spores from HVAC outward airflow mold cross contaminate all rooms and areas of the entire building.
5. With no persons, pets, or plants inside the building during the ozone treatment time and for two hours afterwards, inject high outputs of ozone gas from an ozone generator for six hours into the HVAC's return air duct to kill HVAC mold spores, mold growth colonies, and bacteria. Then do at least four hours of ozone treatment separately in each room and area.
6. Have a qualified and experienced air duct cleaner scrub the insides of all HVAC ducts to remove deposited mold spores, mold colony growth, bacterial growth, and accumulated dust and dirt (mold food). Scrub all room and area walls, ceiling, floors and furnishings with boric acid powder mixed into hot water (one pound of boric per gallon of hot water) to remove any landed/deposited mold spores and mold growth.
7. After the duct cleaning, do a second ozone gas treatment for another six hours inside all HVAC ducts, plus four more hours in each room or area.
8. After the second ozone treatment, use a fogging machine to fog an EPA-registered fungicide such as Tim-Bor into the HVAC equipment and ducts as an additional mold-killing step and to leave a protective coating on all HVAC interior surfaces to help prevent future mold growth. 9. Then repeat the mold testing steps 1 through 4 as described and explained above. Mold lab results will suggest whether the HVAC and building mold problems are now solved, or whether the above mold remediation steps need to be done again.
10. Do year-round preventative building maintenance to keep indoor humidity at less than 70% (above which humidity can cause widespread indoor mold growth), and regularly inspect the building to find and repair roof water leaks, siding water leaks, plumbing leaks, and water intrusion into the crawl space and basement.
