1 North Carolina Childhood Lead Poisoning Prevention Program Division of Environmental Health Lead poisoning can be prevented.
2 Lead-based Paint zPaint manufactures used to put lead pigments in paint because the pigments make the paint last longer, dry faster and cling to surfaces better. zPaint that is disturbed or that is breaking down with age can contaminate dust and soil. zLead is highly toxic. Exposure to it can be dangerous, especially for young children.
3 Child Exposure zChildren are poisoned because they eat lead dust that has gotten on their hands, toys, pacifier, etc. Damage to the child’s health is usually done before symptoms show. zChildren who may be exposed to lead hazards should be tested for elevated blood lead levels.
4 CDC Guidelines zTargeted Screening of 12 and 24 month old children. zN.C. - mandatory screening for recipients of Medicaid, WIC, and HealthChoice. zBlood lead analysis provided at no charge through the State Laboratory.
5 Blood Lead Levels zA blood test tells you what a child’s recent exposure to lead has been. Lead in blood is measured in micrograms of lead per deciliter of blood (ug/dL). 0510152025303540 low risk moderate risk high riskurgent risk A level above 10 is of concern.
6 N.C. Surveillance Data zIn 1999: yMore than 105,000 kids tested. y625 confirmed 10 ug/dL or greater x(50% of EBL children were never retested). y80 confirmed lead poisoning.
7 Health Effects A lead-poisoned child usually seems healthy. Exposure to low levels of lead can permanently affect children. In low levels lead can cause: z Nervous system and kidney damage. z Learning disabilities, attention deficit disorder, and decreased intelligence. z Speech, language, and behavior problems. z Decreased muscle and bone growth. z Hearing damage.
8 Societal Cost zLifetime cost of a moderately poisoned child: $40,000 - $60,000. zReduction in lifetime earnings, medical and special education cost. zDoes not include: reduced family time, anxiety in caring for a lead-poisoned child, decreased stature and hearing ability, increase juvenile delinquency and crime, and hypertension later in life.
9 Adult Exposure zInhalation/Ingestion zLong term health risks yhigh blood pressure yreproductive problems yanemia ykidney failure ymemory and concentration problems ymuscle and joint pain
10 Family Exposure zLead can be dangerous to workers and their families if the worker brings equipment and clothing home from the job site. zVehicles and homes can be contaminated with lead-based paint and dust if safe work practices are not followed.
11 Global Action zCountries that either banned the use of lead paint or severely restricted children’s contact with it: zFrance 1840’s Spain 1931 zGermany 1870’s Yugoslavia 1931 zAustralia 1920 Cuba 1931 zGreat Britain 1926 USA 1978
12 Affected Housing zAccording to HUD estimates: z64 million homes have LBP. z20 million homes with deteriorated LBP likely to cause exposure. z890,000 children with elevated blood lead levels.
13 Hazard? zIs all lead-based paint a hazard? zThe mere presence of lead paint does not mean there is a hazard. zLead-based paint that is intact and covered with several layers of non-lead paint is not a health risk if it is maintained.
15 Safe Work Practices zControl access to the work area zCover the work area with plastic zCover the ground with plastic zShut off HVAC zNo eating, drinking, smoking in work area zProtect occupant and belongings zMist painted surfaces before disturbing
16 Safe Work Practices cont’d zWet sweep zPerform specialized cleaning when project is completed. zChange clothes and shoes before leaving work area. zWash work clothes separately from family laundry. zDispose of wash water down a toilet.
17 Exterior Work zCover the ground with 6 mil plastic sheeting. zMove play equipment at least 20’ away from the work area. zClose all windows and doors. zDaily site cleanup
18 Unsafe Work Practices zStripping paint on-site with methylene chloride-based solutions. zTorch or flame burning zHeating paint with a heat gun above 1100 degrees Fahrenheit. zUncontrolled abrasive blasting, or uncontrolled waterblasting.
19 Specialized Cleaning zUsing a HEPA equipped vacuum cleaner, vacuum from the cleanest areas to the dirtiest areas. Work from the top of the room toward the bottom, cleaning, door frames, chair rails, window sills and troughs, shelves, counters, baseboards and floors.
20 Specialized Cleaning cont’d zWet Cleaning zDetergent solution and two buckets zWork from the cleanest to the dirtiest areas. zChange Rinse water at least once per room. zChange mop heads after each unit/house. zFlush dirty water down the toilet.
21 Preventive Maintenance Program zIn 1997 the North Carolina General Assembly adopted the Childhood Lead Exposure Control Act establishing a voluntary preventive maintenance program (PMP). z The PMP is designed to to reduce childhood lead exposure in pre-1978 rental housing. z The PMP is primary prevention!
22 Who is Eligible to Participate? zParticipation Is Voluntary. zOwners of pre-1978 residential rental property are eligible to participate. zOwners of property identified as a potential source of childhood lead poisoning are also eligible to participate.
23 Who cannot Participate? zChild occupied facilities such as child care centers and schools.
24 Benefits Of Participation zProtect children from exposure to lead-based paint and lead- contaminated dust. zLiability relief from lead poisoning related lawsuits. zProperty Marketing.
25 Maintenance Standard Activities z R epair and repaint interior areas of deteriorated paint. z Adjust doors and windows to minimize friction. z Make interior surfaces smooth and cleanable. z Cap window troughs with vinyl or aluminum. z P re-1950’s property must also: yrepair and repaint exterior areas; ycover bare soil within 3 ft. of the foundation.
26 Maintenance Standard Activities (cont’d) zUse safe work practices to prevent the spread of lead dust. zProtect occupant’s belongings. zUse specialized cleaning to remove residual lead dust. zProvide occupant information. zUndergo annual monitoring.
27 Maintenance Staff Maintenance staff should have proper training and a clear understanding of lead- based paint hazards, safe work practices, occupant protection, and dust cleanup methods.
