Mold Remediation >> Mold Poisonng Symptoms

Four Steps for Responding to Mold Problems 1. Respond quickly with appropriate actions to stop water damage and limit potential exposure to occupants 2. Identify: The cause of the moisture problem The extent of contamination The safety precautions for remediation 3. Implement remediation Remove damaged material that cannot be effectively cleaned or Mold Poisonng Symptoms that is more expensive to clean than replace.  

Clean and salvage materials that are not severely damaged. Dispose of the damaged material in an appropriate manner. Moldy materials can be sent to a regular landfill. Seal them in plastic bags to protect workers while the material is in transit. 4. Repair Mold Poisonng Symptoms and replace removed materials incorporating the necessary changes to correct the underlying moisture problem. Dry out the area being remediated before closing in a wall or ceiling. 

General Recommendations Carefully assess the problem before beginning the cleanup. If the moisture problem started in a closed cavity (wall, ceiling or floor), Mold Poisonng Symptoms the mold that can be seen may be only a fraction of the mold present. Put another way, there may be a lot more mold in the wall than you think there is. 

Assume and prepare for the worst, while hoping for the best. Discuss the planned work with the owner Mold Poisonng Symptoms and occupants. It is easier to address their concerns before you begin the work. Perform the work in a manner that minimizes the risk to the workers doing the remediation and the occupants of the building. 

Opening moldy wall cavities can release millions of mold spores and mold parts; Mold Poisonng Symptoms inhaling these spores and body parts along with their associated toxins can potentially cause health problems. Make certain that the workers understand how to do the work and what they need to do to protect themselves and the occupants of the building.. 

Dispose of the damaged material in an appropriate manner. Moldy materials can be sent to a regular landfill. Sealing them in plastic bags protects workers while the material is in transit. Whenever possible remove moldy material through a window Mold Poisonng Symptoms or door to minimize the chance that mold will be released into the rest of the building. 

Transporting moldy materials through clean areas should be minimized. Clean before you dry. Drying before cleaning can cause mold to become airborne. You do not have to kill mold in order to clean up mold. Cleaning up mold in essence means removing mold. Biocides can be more dangerous than the mold. Don't use bleach; Mold Poisonng Symptoms use soap and water. 

Bleach kills, but it does not clean (remove) the mold. In single family residential buildings it is often possible to pressurize the occupied portion of the building rather than to depressurize the work area. For example, if the problem is a moldy crawlspace, Mold Poisonng Symptoms pressurize the upstairs using a fan door. Workers with appropriate personal protection can perform the work by entering through an exterior access, avoiding airlocks, protection of furnishings and passing contaminated material through the occupied space. 

If there is not an external access, make one. This makes the clean-up much simpler and safer. Attics, garages, basements Mold Poisonng Symptoms and easily isolated additions can be treated this way. Special attention must be paid to any air ducts that are located in the contaminated area. Deciding Whether a Material Should be Replaced or Salvaged 

The general guidance is that soft, absorbent materials that contain a carbon source easily accessible to mold should be discarded unless there are compelling reasons to attempt to salvage them. Paper, textiles Mold Poisonng Symptoms and paper covered gypsum board are examples of materials that should usually be discarded. 

If there is only a small amount of obviously superficial contamination, Mold Poisonng Symptoms these materials may be cleaned (soap and water). If they have more than a few colonies, but are worth enough to salvage (e.g. books, art work, musical instruments, vintage carpets), they are worth enough that the salvage work should be performed by specialists. 

Materials like lumber, plywood, oriented strand board (OSB), particle board, paper covered gypsum board may Mold Poisonng Symptoms or may not be salvageable. The base case test is - has the material lost structural integrity? Most mold species cannot degrade the cellulose-lignin cell wall of intact lumber (there are, of course, a few exceptions - stachybotrys and fusarium for example). 

So mold growing on solid lumber is most likely a surface contamination issue, not a structural issue. It can be cleaned, dried and salvaged. If solid lumber has lost structural integrity, then it has been colonized by wood decay fungi and probably certain bacteria Mold Poisonng Symptoms and that portion must be replaced. However, composite materials that are composed of wood held together with adhesives are a different story. 

Many of the adhesives can be degraded by fungal hyphae, at which time they begin to lose structural integrity (visualize hardboard siding or particle board that has turned to mush). So if one of these materials has only superficial mold, it can be cleaned Mold Poisonng Symptoms and salvaged; but if it's decomposing it should be replaced. A good motto is "when in doubt, throw it out." 

Generally, the more a product is composed of solid wooden pieces the more resistant it is to penetration and damage by mold. Use a pocket knife Mold Poisonng Symptoms or ice pick to determine the depth of damage. For rotted wood, cut it out. For moldy wood, clean it with soap and water and elbow grease. Do not sand it. If you have to sand it to clean it, it's not mold, it's rot. If it's rot, cut it out and get rid of it. 

Wood may be permanently stained (discolored) after you've clean it. If this bothers you, Mold Poisonng Symptoms paint it with latex paint (because latex paint breathes). In rare instances sanding may be justified such as on structural members that may be difficult to remove. Leave such a decision to a qualified expert.
