LEAD BASED PAINT
Lead-based paint is hazardous to your health.
Lead-based paint is a major source of lead poisoning for children and can also
affect adults. In children, lead poisoning can cause irreversible brain damage
and can impair mental functioning. It can retard mental and physical development
and reduce attention span. It can also retard fetal development even at
extremely low levels of lead. In adults, it can cause irritability, poor muscle
coordination, and nerve damage to the sense organs and nerves controlling the
body. Lead poisoning may also cause problems with reproduction (such as a
decreased sperm count). It may also increase blood pressure. Thus, young
children, fetuses, infants, and adults with high blood pressure are the most
vulnerable to the effects of lead.
Children should be screened for lead poisoning.
In communities where the houses are old and deteriorating, take advantage of
available screening programs offered by local health departments and have
children checked regularly to see if they are suffering from lead poisoning.
Because the early symptoms of lead poisoning are easy to confuse with other
illnesses, it is difficult to diagnose lead poisoning without medical testing.
Early symptoms may include persistent tiredness, irritability, loss of appetite,
stomach discomfort, reduced attention span, insomnia, and constipation. Failure
to treat children in the early stages can cause long-term or permanent health
damage.
The current blood lead level which defines lead poisoning is 10 micrograms of
lead per deciliter of blood. However, since poisoning may occur at lower levels
than previously thought, various federal agencies are considering whether this
level should be lowered further so that lead poisoning prevention programs will
have the latest information on testing children for lead poisoning.
You can be exposed to lead from paint.
Eating paint chips is one way young children are exposed to lead. It is not the
most common way that consumers, in general, are exposed to lead. Ingesting and
inhaling lead dust that is created as lead-based paint "chalks," chips, or peels
from deteriorated surfaces can expose consumers to lead. Walking on small paint
chips found on the floor, or opening and closing a painted frame window, can
also create lead dust. Other sources of lead include deposits that may be
present in homes after years of use of leaded gasoline and from industrial
sources like smelting. You can also generate lead dust by sanding lead-based
paint or by scraping or heating lead-based paint.
Lead dust can settle on floors, walls, and furniture. Under these conditions,
children can ingest lead dust from hand-to-mouth con- tact or in food. Settled
lead dust can re-enter the air through cleaning, such as sweeping or vacuuming,
or by movement of people throughout the house.
Older homes may contain lead based paint.
Lead was used as a pigment and drying agent in "alkyd" oil based paint. "Latex"
water based paints generally have not contained lead. About two-thirds of the
homes built before 1940 and one-half of the homes built from 1940 to 1960
contain heavily-leaded paint. Some homes built after 1960 also contain
heavily-leaded paint. It may be on any interior or exterior surface,
particularly on woodwork, doors, and windows. In 1978, the U.S. Consumer Product
Safety Commission lowered the legal maximum lead content in most kinds of paint
to 0.06% (a trace amount). Consider having the paint in homes constructed before
the 1980s tested for lead before renovating or if the paint or underlying
surface is deteriorating. This is particularly important if infants, children,
or pregnant women are present.
You may choose to have a testing laboratory test a paint sample for lead.
Inspections and lab fees for lead sampling and analysis are currently $150.00
per sample, to see full pricing on other inspection fees

The process for lead paint analysis:
-
Get sample containers from the lab or use re-sealable plastic bags.
Label the containers or bags with the consumer's name and the location in
the house from which each paint sample was taken. Several samples should be
taken from each affected room (see HUD Guidelines discussed below).
-
Use a sharp knife to cut through the edges of the sample paint. The lab
should tell you the size of the sample needed. It will probably be about 2
inches by 2 inches.
-
Lift off the paint with a clean putty knife and put it into the
container. Be sure to take a sample of all layers of paint, since only the
lower layers may contain lead. Do not include any of the underlying wood,
plaster, metal, and brick.
-
Wipe the surface and any paint dust with a wet cloth or paper towel and
discard the cloth or towel.
The U.S. Department of Housing and Urban Development (HUD) recommends that
action to reduce exposure should be taken when the lead in paint is greater than
0.5% by lab testing or greater than 1.0 milligrams per square centimeter by
X-ray fluorescence. Action is especially important when paint is deteriorating
or when infants, children, or pregnant women are present. Consumers can reduce
exposure to lead-based paint.
If you have lead-based paint, you should take steps to reduce your exposure to
lead. You can:
1. Have the painted item replaced.
You can replace a door or other easily removed item if you can do it
without creating lead dust. Items that are difficult to remove should be
replaced by professionals who will control and contain lead dust.
2. Cover the lead-based paint.
You can spray the surface with a sealant or cover it with gypsum
wallboard. However, painting over lead-based paint with non-lead paint is
not a long-term solution. Even though the lead-based paint may be covered by
non-lead paint, the lead-based paint may continue to loosen from the surface
below and create lead dust. The new paint may also partially mix with the
lead-based paint, and lead dust will be released when the new paint begins
to deteriorate.
3. Have the lead-based paint removed.
Have professionals trained in removing lead-based paint do this work.
Each of the paint-removal methods (sandpaper, scrapers, chemicals,
sandblasters, and torches or heat guns) can produce lead fumes or dust.
Fumes or dust can become airborne and be inhaled or ingested. Wet methods
help reduce the amount of lead dust. Removing moldings, trim, window sills,
and other painted surfaces for professional paint stripping outside the home
may also create dust. Be sure the professionals contain the lead dust.
Wet-wipe all surfaces to remove any dust or paint chips. Wet-clean the area
before re-entry.
You can remove a small amount of lead-based paint if you can avoid creating
any dust. Make sure the surface is less than about one square foot (such as
a window sill). Any job larger than about one square foot should be done by
professionals. Make sure you can use a wet method (such as a liquid paint
stripper).
4. Reduce lead dust exposure.
You can periodically wet mop and wipe surfaces and floors with a high
phosphorous (at least 5%) cleaning solution. Wear waterproof gloves to
prevent skin irritation. Avoid activities that will disturb or damage lead
based paint and create dust. This is a preventive measure and is not an
alternative to replacement or removal.
Professionals are available to remove, replace, or cover lead-based paint.
Contact your state and local health departments lead poisoning prevention
programs and housing authorities for information about contractors who can
safely remove lead-based paint.
The U.S. Department of Housing and Urban Development (HUD) prepared guidelines
for removing lead-based paint which were published in the Federal Register,
April 18, 1990, page 1455614614. Ask contractors about their qualifications,
experience removing lead-based paint, and plans to follow these guidelines.
-
You should keep children and other occupants (especially infants,
pregnant women, and adults with high blood pressure) out of the work area
until the job is completed.
-
You should remove all food and eating utensils from the work area.
-
You should remove all furniture, carpets, and drapes and seal the work
area from the rest of the house. The contractor also should cover and seal
the floor unless lead paint is to be removed from the floor.
-
You should assure that workers wear respirators designed to avoid
inhaling lead.
-
You should not allow eating or drinking in the work area. Contractors
should cover and seal all cabinets and food contact surfaces.
-
You should dispose of clothing worn in the room after working. Workers
should not wear work clothing in other areas of the house. The contractor
should launder work clothes separately.
-
You should clean up debris using special vacuum cleaners with HEPA (high
efficiency particulate air) filters and should use a wet mop after
vacuuming.
-
You should dispose of lead-based paint waste and contaminated materials
in accordance with state and local regulations.
Government officials and health professionals continue to develop advice about
removing lead-based paint. Watch for future publications by government agencies,
health departments, and other groups concerned with lead-paint removal and
prevention of lead poisoning.
