Water Damage >> Leaking Water Heater

Use (undamaged) HVAC system and de-humidifiers to aid in reducing relative humidity levels to below 50% if possible to aid in drying of wetted materials Leaking Water Heater and to prevent unaffected materials from absorbing moisture in the air. Remove undamaged paper items from affected area if high humidity exists. 

Work with occupying agency as needed to inventory damaged items. Moisture meter should be employed to determine extent of wetted areas and to verify drying process and completion. 11. If walls or flooring or other materials are not dry within 48 hours, Leaking Water Heater document areas-mark out areas and meet with DAS representatives to lay out a plan of remedial action. 

In the event of water infiltration We ask that you contact Bill Falletti or yourProperty Agent so that the proper clean upactions will get started as soon as possible to avoid possible IAQ problems due to mold – Materials that are wet need to be properly addressed. – Source of water stopped AND Leaking Water Heater corrected (so it isn't likely to reoccur). 

Cleanup Methods Method 1: Wet vacuum (in the case of porous materials,some mold spores/fragments will remain in the material butwill not grow if the material is completely dried). Steamcleaning may be an alternative for carpets and someupholstered furniture.Method 2: Damp-wipe surfaces with plain water or Leaking Water Heater withwater and detergent solution (except wood —use wood floorcleaner); scrub as needed.

Method 3: High-efficiency particulate air (HEPA) vacuumafter the material has been thoroughly dried. Dispose of thecontents of the HEPA vacuum in well-sealed plastic bags.Method 4: Discard - remove water-damaged materials and Leaking Water Heater seal in plastic bags while inside of containment, if present. Dispose of as normal waste. 

HEPA vacuum area after it is dried. Personal Protective Equipment (PPE)Minimum: Gloves, Leaking Water Heater N-95 respirator, goggles/eyeprotectionLimited: Gloves, N-95 respirator or half-facerespirator with HEPA filter, disposable overalls,goggles/eye protectionFull: Gloves, disposable full body clothing, head gear,foot coverings, full-face respirator with HEPA filter 

Containment Limited: Use polyethylene sheeting ceiling to flooraround affected area with a slit entry Leaking Water Heater and coveringflap; maintain area under negative pressure withHEPA filtered fan unit. Block supply and return airvents within containment area.Full: Use two layers of fire-retardant polyethylenesheeting with one airlock chamber. 

Maintain areaunder negative pressure with HEPA filtered fan exhausted outside of building. Block supply and Leaking Water Heater return air vents within containment area.Musty odors Musty odors =volatile organic compounds. musty odors can be caused by mold but can be from other sources… If there is no water anywhere then mustyodors are probably not caused by mold. 

Ifthere is water, mold probably plays a role, Leaking Water Heater butmay not be the entire problem.Source of info: Dr. Harriet Burge EMLab P&K Chief Aerobiologist and Directorof Scientific Advisory BoardIf there are reports of a lingering musty orunknown odor We ask that you contact Bill Falletti orProperty Agent so that the situation can beinvestigated as soon as possible 

Don't ignore occupant IAQconcerns Contact DAS Leasing and report concerns sothat they can be investigated Leaking Water Heater and addressed Mold Spores and Allergens Recent research…indicates that allergens are released from a spore duringthe germination process… So.. 

Exposure to allergens from airborne mold spores occurs only if theparticular types of mold spores that are inhaled into the respiratory tractfind the correct amount of moisture, nutrients, Leaking Water Heater oxygen needed to beginthe germination process… Different molds germinate under differing conditions…not all fungi willrelease allergens when inhaled 

Process may take from a few minutes to many hours. Non living spores may not trigger allergic reactions as previously thoughtCommon fungal allergens Basidiospores: mushrooms, rusts, smuts,brackets, Leaking Water Heater and puffballs (mostly outdoors) Alternaria alternata: most common sensitizeramong fungi (in spite of the fact thatconcentrations in air are generally much lowerthan for many other fungi) 

Penicillium Aspergillus Cladosporium What is a toxigenic or Leaking Water Heater toxic mold? A mold that produces toxins (also calledmycotoxins) Not all types of molds produce mycotoxins Some are extremely poisonous/toxic wheningested..like alfatoxin Mycotoxins…health effects 

"Health effects for most of the mycotoxins are known only from either agriculturalenvironments, Leaking Water Heater or from laboratory experiments, and virtually all of the data involves ingestionof the mycotoxins. Article by Dr. Harriet Burge July 2005 issue of the Environmental Reporter "

The fact remains that no research has documented that anyone has ever been exposed toenough mycotoxin from exposure to indoor fungal growth to actually cause any of his/hersymptoms with the possible exception of agricultural environments. In fact, Leaking Water Heater there are nopublications that I can find that actually document the amount of mycotoxin exposure in amoldy indoor environment." 

Aren't Mycotoxins Part of the Indoor Air Problem?By Dr. Harriet Burge, February 2011 issue of Indoor Environment Connections "Extrapolating from the amount of toxin necessary to cause health effects by ingestion, Leaking Water Heater and,given that the toxin content of individual spores is quite low.

Inhalation exposure in nonagricultural environments (i.e. in normal homes Leaking Water Heater and offices) to enough spores of even themost toxic strains to reach a dose likely to produce human health effects is unlikely andprobably very rare. "Article by Dr. Harriet Burge July 2005 issue of the Environmental Reporter
