2009 Ice Storms

Here we go again. over a million people are without power due to ice storms across the Midwest stretching down into Texas. Ice storms are a huge problem for buildings constructed in areas where they are not common.

One of the things that is happening is warmer temperatures in the outer atmosphere mean there is more moisture. When this moisture condenses it begins to fall as rain. If surface conditions are below freezing, the rain drops freeze and become ice. When upper atmosphere temperatures are cold the water falls as snow not rain. Snow is less damaging since it weighs about 1/10th as much as ice.

In addition to the power outages – we should anticipate an increase in building roof collapses. Steeper sloped roofs are better equipped to deal with this extreme weather where at least some of the ice will generally slide off. Flat roofs tend to accumulate the ice and are more likely to collapse from the load.

Some areas have been reported to already have about 6 inches of ice with another 6 inches potentially falling in the next 24 hours. Twelve inches of ice on a roof weighs about 60 pounds. That is a huge amount of weight for a roof since many roofs in areas that are not commonly exposed to the weight from ice and snow have been built to hold a minimum of twenty pounds. 

We should also anticipate problems with frozen plumbing and ice dams.

:256 Mold and Water Damage

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:256 EcoTip: With the United States being pummeled by more hurricanes this year than since 2005 – the year of Katrina – it is time to look at some of the lessons learned. A January 20, 2006 CDC report examined the knowledge recovery workers had regarding personal protective equipment and mold. The paper cites evidence that exposure to mold and damp buildings can have adverse health complications.

Over the next several days my tips will focus on this and other lessons learned from Katrina that can be used during any construction activities whether it be due to catastrophic damage such as from tornadoes or hurricanes or a routine home upgrade or repair.

Suggested Review:

This is the first in a series of EcoTips about protecting oneself when remodeling and working around buildings when participating in disaster recovery such as occurred with hurricane Katrina and is going on now with Ike. This information is timely since 2008 is the most active hurricane season since 2005 and many buildings are being damaged.

According to CDC:

In 2004, the Institute of Medicine (IOM) reviewed the literature regarding health outcomes related to damp indoor spaces (4). In addition to the risk for opportunistic fungal infections in immunocompromised persons, IOM found sufficient evidence for an association between both damp indoor spaces and mold and upper respiratory symptoms (nasal congestion and throat irritation) and lower respiratory symptoms (cough, wheeze, and exacerbation of asthma).

Basic mold awareness training and training regarding cleaning small areas of mold is available on-line at http://www.restcon.com/training.restcon.com/MAT/index.php
