Health problems and illnesses encountered by unprotected workers, first-responders, home-owners, and volunteers in recovery and restoration of moldy indoor environments after hurricanes, typhoons, tropical storms, and flooding damage are a growing concern for healthcare providers and disaster medicine throughout the world. Damp building materials, particularly cellulose-containing substrates, are prone to fungal (mold) and bacterial infestation. During remediation and demolition work, the Airborne concentrations of such microbes and their byproducts can rise significantly and result in an xposure risk
Water damage can originate by different sources such as a broken dishwasher hose, a washing machine overflow, a dishwasher leakage, broken/leaking pipes, flood waters, groundwater seepage, building envelope failures (leaking roof, windows, doors, siding, etc.) and clogged toilets. According to the Environmental Protection Agency, 13.7% of all water used in the home today can be attributed to plumbing leaks.[2] On average that is approximately 10,000 gallons of water per year wasted by leaks for each US home. A tiny, 1/8-inch crack in a pipe can release up to 250 gallons of water a day.[3] According to Claims Magazine in August 2000, broken water pipes ranked second to hurricanes in terms of both the number of homes damaged and the amount of claims (on average $50,000 per insurance claim[citation needed]) costs in the US.[4] Experts suggest that homeowners inspect and replace worn pipe fittings and hose connections to all household appliances that use water at least once a year. This includes washing machines, dishwashers, kitchen sinks, and bathroom lavatories, refrigerator icemakers, water softeners, and humidifiers. A few US companies offer whole-house leak protection systems utilizing flow-based technologies. A number of insurance companies offer policyholders reduced rates for installing a whole-house leak protection system.
