What do lead based paint inspections focus on?
they focus attention on the sources of lead that could poison children and reduce the
cost of lead hazard control by identifying which surfaces are coated with lead-based
paint.
What are certified inspectors capable of?
1. identifying the lead-based painted surfaces in housing
2. Certify the results of an inspection in writing.
3. Conduct post-hazard control clearance sampling to determine if
a. the specified hazard control safety was conducted
b. the area is safe for unprotected workers to enter
c. the area is a safe place for residents and young children to live
An inspector must be able to...
- be knowledgeable about the performance & limitations of all lead testing technique
and methods
-familiar with all lead testing methods and sample techniques & standards
- able to perform math calculations
-skilled in understanding results
- can make objective decisions
-able to implement and interpret quality control procedures
When do lead inspectors get a refresher course & post-course examination?
Every 3 years
What is the lead-based paint disclosure rule?
In the late 1996, the EPA and HUD created the lead-based paint disclosure rule that
allows prospective purchasers of housing built before 1978 to have a lead-based paint
or risk assessment to determine whether lead based paint or lead-based paint hazards
exist in housing
Why is lead more common in children of lower income and/or people of color?
1. Worse physical condition and older housing
2. More lead-contaminated dust in the home
3. high lead levels in urban soil
4. Poor Nutrition
5. Lead in drinking water
What is the largest remaining source of lead exposure in children?
contaminated dust and soil
What is Title X?
the residential lead-based paint HAzard reduction Act ( Title X) of the community and
housing Act of 1992 shifted the focus of federal legislation from acting only on existing
lead-based paint hazards to preventing new hazards from occurring
What is lead based paint?
Paint, varnish, shellac, or other coating on surfaces that contain 1.0 mg/cm² or more of
lead or 0.5% by weight
What are Lead-based paint hazards?
,any condition that causes exposure to lead contaminated dust, lead contaminated soil,
or lead-contaminated paint that is deteriorated or present in accessible surfaces, friction
surfaces, or impact surfaces that would result in adverse human health effects as
identified by the EPA administrator under TSCA Section 403
What is Deteriorated paint?
any interior or exterior paint that is peeling, chipping, chalking, or cracking, or is located
on an interior/exterior surface or fixture that is damaged.
What is an accessible surface?
Surface that protrudes from the surrounding area to the extent that a child can chew the
surface and is within 3 feet of the floor or ground (Window sills, railing, stair tread)
what is a friction surface?
an interior/exterior surface that is subject to abrasion/friction (windows, floor, staircases)
what is an impact surface?
an interior/exterior surface that is subject to damage from repeated impacts (parts of
door frames)
What is the primary purpose of HUD Guidelines?
The guidelines purpose is to guide people involved in identifying and controlling lead-
based paint hazards in housing.
who can use HUD guidelines?
the guidelines can be used by state and local governments or the private sector as a
source of standards and procedures for testing and abating lead based paint in public
and privately owned housing, day care centers, and public buildings that exhibit
conditions similar to those in residential structures.
What are the three main reasons lead has been used in PAINT?
1. as a pigment
2. to add durability and corrosion control
3. as a drying agent
What are the principal industrial uses and products containing lead?
1. electrical storage batteries
2. ammunition
3. various chemicals
4. sinkers for fishing
What is the major cause of lead exposure for adults?
the workplace
experts agree childhood lead poisoning can be attributed to
1. Lead based paint in housing
2. lead in interior/exterior surface dust (through hand-to-mouth transmission)
3. urban soil (contaminated from lead-based paint, gasoline, and industrial sources)
4. drinking water (primarily from leaded solder; brass fittings and fixtures; and service
lines)
What does lead-based paint kill?
kills mold and mildew
What is the most common route of lead exposure in the children?
the more common route of exposure is by ingesting lead-bearing dust that is formed by
the paint when it deteriorates, chalks, or is disturbed through renovation or even
, abrasion from the opening and closing of windows and other friction and impact
surfaces.
Lead in surface dust and soil of all types can come from. . .
- weathering and chipping of lead-based paint
- scraping and sanding of lead-based paint in preparation for refinishing; renovations
that break surfaces painted with lead-based paint
- abrasion and/or impact on door and windows
When and where is there a higher exposure to lead in soil?
-if the house has exterior lead based paint, there is a higher likelihood that the soil lead
levels will be greater than EPA's level of concern (currently 400 parts per million).
- lead contamination is most likely to be found around the outside of the house at the
roof drip line.
What are some factors that may lead to lead in drinking water?
1. the amount and age of lead-containing materials susceptible to corrosion
2. the amount of time the water is in contact with these materials
3. the corrosiveness of the water
Can lead-based paint inspectors collect water samples?
No. Title X does not define lead contamination in water as a lead-based paint hazard.
Additionally, under the EPA training and certification rules, (Section 402 of TSCA),
water sampling is included as a part of a risk assessment, not an INSPECTION.
Therefore, lead-based paint inspectors cannot collect water samples or recommend
corrective measures.
What ares some sources of lead exposure in the air?
Lead gasoline, smelters, battery factories, combustion of oil, coal, waste, municipal
waste, windblown dust. Even activities such as abrasive blasting, sanding, burning, or
welding on steel structures coated with lead-containing paints may produce very high
concentrations of lead dust and fumes.
What are some ways in which food is contaminated with lead?
1. from containers with lead solder, lead glaze, or other materials with lead, especially if
contents are acidic in nature
2. by airborne lead from industrial or automobile emissions deposited onto crops or
water
3. by uptake into food crops from lead in soil or pesticide applications
4. during transportation or processing
What are some occupations in which adults may be more likely to be exposed to
lead?
adults who work in certain industries, such as smelting, auto body repair shops, painting
shops, scrap metal works, electrical work, demolition, and construction can be at risk to
lead poisoning.
What are the three systems where the effects of lead are most dangerous?
1. the central and peripheral nervous systems
2. the cardiovascular system, including the blood forming system
3. the kidneys
Exposure to high concentrations of lead can cause?
Retardation
Convulsions
