Environmental Hazards
Environmental Hazards Our job as your professional
home inspector is to alert you, to the extent possible, to unknown problems and potential environmental hazards in your current
or potential house. Ours is a non-invasive visual inspection of your property which can alert you to possible problems.
We are licensed by the State of New Jersey, to perform tests for these hazards: Radon:
Radon is a radioactive gaseous element produced in the disintegration
of radium, a radioactive metallic element. It cannot be detected by the senses and can be confirmed only by sophisticated
instruments and laboratory tests. The gas enters a house through pores and cracks in the concrete or through floorboards of
poorly ventilated crawlspaces, especially when wet ground allows the gas to escape easily through the soil and disperse in
the atmosphere. Radon is a lung carcinogen: the National Academy of Sciences estimates radon causes some 15,000 to 22,000
lung cancer deaths annually. The U.S. Surgeon General and the EPA recommend all houses be tested for radon. Houses with high
radon levels can be fixed. Excerpts from U.S. Environmental Protection Agency, “Indoor Radon”. Termites or other wood-destroying organisms:
Termites, which play a positive role in recycling wood and plant material, become a problem when
they consume structural lumber. Every year thousands of U.S. housing units require termite treatment. These pests cause serious
damage to wooden structures and posts and can also attack stored food, household furniture, and books. Successful termite
management requires special skills, including a working knowledge of building construction and an understanding of termite
biology and identification. In most cases, it is advisable to hire a professional pest control company for the inspection
and control problem. Wood-boring
beetle larvae feed on wood and wood products. Adults of some species bore holes into plaster, plastic, and soft metals.
Many species cause problems when emerging from wood in newly constructed buildings because they leave small circular or oval
exit holes in the wood. To avoid these problems, infested wood must be kiln-fried before being used for lumber. The species
Deathwatch Beetles is primarily found in soft woods (girder, beams, foundation timbers, some types of furniture, with some
species attacking books). False Powderpost female beetles bore a tunnel, or egg gallery, into wood or other materials, then
deposit eggs in pores or cracks within the tunnel. Adults of some species bore through such soft metal as lead and silver,
as well as plaster and other non-wood materials. Affected structural wood should be removed and replaced whenever possible.
Wood Wasps and Horntails. Wood wasp damage in
buildings is likely to be more cosmetic than structurally weakening. Emerging wood wasps can chew through any substance: wallboard
or plaster walls, hardwood floors, carpeting, linoleum, non-ceramic floor tiles, and other interior surfaces.
Carpenter Ants. Several species can damage wood in building and
other structures. Though ants don’t eat wood, they bore into it to make their nests, sometimes causing serious structural
damage. Also, they nest in hollow doors, cracks and crevices, furniture, wall voids, and termite galleries. New building infestation
occurs when land-cleaning in the area disturbs existing native colonies.
Excerpts from University of California Agriculture & Natural Resources, UCIPMOnline, “Statewide Pest
Management Program”. We sample on request
for these hazards:
Asbestos: Asbestos is a mineral fiber that can be positively identified only with a special type of microscope. There are several
types of asbestos fibers. In the past, asbestos was added to many products to strengthen them and provide fire resistance
and heat insulation. If disturbed, asbestos material may release asbestos fibers which can be inhaled into the lungs. Asbestos
material that crumbles easily if handled or which has been scraped, sawed, or sanded into a powder is more likely to create
a health hazard. Breathing high levels of asbestos fibers can lead to an increased risk of lung cancer, mesothelioma (cancer
of lining of chest and abdominal cavity), and asbestosis (lungs scarred with the tissue). Houses built between 1930 and 1950
may have asbestos insulation. Most of today’s products do not contain asbestos. If asbestos material is more than slightly
damaged or you plan changes that might disturb it, you require a professional for repair and removal. Before home remodeling,
find out if asbestos is present.
Excerpts from U.S. Environmental Protection Agency “Asbestos and Vermiculite”.
Mold:
Mold (fungi) is present everywhere, indoors and outdoors. There
are more than 100,000 species of mold, at least 1,000 of which are common in America. Species of Cladosporium, Penicillium,
and Aspergillus are some of the most commonly found species. Mold most likely grows in bathrooms, basements, and anywhere
else where there is dampness or water. Many types of mold routinely encountered aren’t hazardous to healthy individuals.
Too much exposure to mold may cause a worsening of such conditions as asthma, hay fever, or other allergies. Fevers and breathing
problems in a vulnerable individual are possible but unusual. When moldy material becomes damaged or disturbed, spores, which
are reproductive bodies similar to seeds, can be released into the air. Exposure can occur if people inhale the spores, directly
handle moldy material, or accidentally ingest the spores. Since all molds need water to grow, mold can grow almost anywhere
where there is high humidity, dampness, or water damage. Most often molds are confined to areas near the water source. Removing
the source of moisture through repairs or dehumidification is crucial in preventing mold growth. Correcting underlying water
damage and cleaning the affected area is the best way to treat mold. If mold contamination is extensive, a professional abatement
company may be needed. Excerpts from The New York City Department of Health & Mental Hygiene, Environmental &
Occupational Disease Epidemiology, “Facts About Mold”.
Indoor Air Quality: While mold colonies and the spores they produce can cause allergic
reactions, things such as pet dander, VOC’s (volatile organic compounds), dust, and other allergens can affect
the air we breathe. Using air sampling techniques to IESO standards (www.iestandards.org ), we can sample for these and others issues.
