Environmentally Friendly Mold Remediation Techniques That Significantly Reduce Childhood Asthmaprecaution, fans that create airflow by blowing should no longer beused once visible mold appears, and drying should then proceedunder more controlled conditions to avoid dispersing mold particles.Moisture source(s) that have led to mold growth must be identifiedand understood in order to plan an effective mold remediationproject. Finding the locations of excess moisture, identifying themechanisms for its accumulation or infiltration, and tracing pathwaysof its migration can also aid in finding and assessing the likelihood ofencountering further growth.Oftentimes the source of moisture cannot be accurately pinpointeduntil the water damaged drywall is removed. For example, once thedrywall is removed, small openings in window or door caulking can beeasily found close to the heaviest mold concentrations on wood or drywall.Those responsible for correcting and preventing mold problemsshould recognize that moisture in any of its phases (ice, water, andvapor) must be adequately controlled. For example, moisture may bepresent at a material’s surface as high relative air humidity. Moisturecan also be absorbed into porous and semi-porous materials and maymigrate under surface coverings, around furniture, and betweencomponents at joints. Understanding the moisture sources and dynamicsinvolved in a particular situation may require professional assistance.During the mold remediation project itself, it is necessary to controlthe use or production of water. For example, cleaning techniquesshould use water-based solutions sparingly and must include rapiddrying following the cleaning steps, or the water-based cleaner shouldinclude some mold inhibitor/disinfectant. Power washing should notbe performed if vulnerable material, such as wallboard and sheet rock,might get wet. Power washing of wood trusses or furring – inbuildings before drywall or AC ducts are in – can be quite effectivewhen disinfectant/mold inhibitor is added to the auxiliary powercleaner mixing chamber.1 See Appendix B resources for detailed decontamination protocols.82
Environmentally Friendly Mold Remediation Techniques That Significantly Reduce Childhood AsthmaMold will always grow again where moisture issues are notaddressed adequately. Those planning and carrying out moldremediation should consider how to ensure and document thatmoisture problems have been resolved.Seepage cannot always be eliminated. Very often ground waterseepage into a building cannot be eliminated. Improving drainage canhelp. Adding rain gutters to direct the water away from the sides ofbuildings can help. But sometimes seepage cannot be eliminated.In such cases you consider Plan B. What is Plan B? Perhaps usingfiberglass covered drywall at the bottom of problem walls. Perhapssimply hanging the newly installed drywall off of the floor and out ofcontact with moist concrete flooring is enough.Use real wood baseboard rather than synthetic base. Paint both sideswith mold inhibiting paint and hang the base a little off of the floorso that it is not in contact with the wet floor.Do not use carpet in these areas.Appendix D includes discussion on water problems in basements.9.7 Cleaning of Remediation EquipmentEquipment used during remediation may need careful cleaningdepending on how much mold was released during cleaning. In thecase of a “Minimal” problem, tools can usually be adequately cleanedby damp wiping or washing with soap and water. With “Moderate”and “Major” problems, a protocol for decontaminating workers andequipment should be developed.In the case of “Major” problems, containment should be constructedto include a separate decontamination chamber and should allowplenty of room to work comfortably. All equipment should be HEPAvacuumed, damp wiped with disinfectant, and bagged before beingremoved from the work area. This includes cleaning all tools, negativeair machines, waste-containing bags, outer clothing, respirators, gloves,and goggles. Workers should wear at least an N-95 respirator whencleaning or replacing HEPA filtered equipment components. We83
