Abatement – A procedure that eliminates lead-based paint hazards or lead-based paints. The four types of abatement methods are replacement, removal, enclosure and encapsulation.
Accreditation – the process of authorizing a training course provider to prepare risk assessors, lead inspectors, clearance examiners, abatement contractors, and other lead professionals for certification.
“Affected” Property – A residential property built prior to 1950 that contains at least one rental dwelling unit OR a residential property built between 1950 and 1978 and the owner has elected to comply in order to reduce his or her liability.
Capillary Blood Lead Test – a blood lead test for which the blood sample is drawn using a finger lance to break the skin, followed by (1) drawing the blood from the cut into a capillary tube or other collection device, or (2) placing drops of blood onto a piece of filter paper.
Certified – The designation for contractors who have completed training and other requirements to allow them to carry out inspections, risk assessments or abatements safely. Inspectors, risk assessors, and abatement contractors must be certified by the appropriate local, tribal, state, or Federal agency.
Chelation – A medical drug treatment for lead poisoning.
Clearance – an activity conducted for the purpose of establishing proper completion of interim controls of lead hazards. A clearance examination can be conducted by a licensed risk assessor, lead inspector or clearance examiner. The clearance examination includes a visual examination of the completed work and additional dust samples to be tested for lead.
Defect – A “defect” is any part of a home that has flaking, chipping or peeling paint, or a structural problem such as: leaking ceiling/roof, faulty plumbing, lack of heat or broken doors and windows.
dl – Short for deciliter. A deciliter 1/10 of a liter, or a little less than half a cup of liquid. This measurement is used when measuring blood in the body.
Deteriorated lead-based paint – Any lead-based paint that is blistering, flaking, peeling, worn, chipping, chalking, cracking, or otherwise becoming separated from the surface to which it was applied.
Encapsulation – An abatement method where a lead-painted surface is coated with a special liquid paint that hardens and prevents lead dust from being released.
Enclosure – An abatement method in which a lead-painted surface is covered with wallboard, paneling, or other approved material to prevent lead dust from being released.
High-Efficiency Particulate Air (HEPA) filter – A filter that can remove up to 99.97% of lead particles and prevent them from being redistributed into the air. HEPA filters are used on respirators and vacuum cleaners to prevent lead exposure from projects that that disturb lead-based paint.
Inspection (of paint) – An evaluation to determine if lead-based paint is present and where it is located.
Inspector – An individual who has completed training from an EPA-approved program and has been licensed to perform a lead-based paint inspection
Interim Controls – a set of measures that temporarily reduce lead hazards. Such measures include specialized cleaning, repairs, maintenance, painting, and temporary containment. Interim controls must be periodically monitored to ensure they are still effective.
Lead-based Paint – any paint or other surface coating equal to or exceeding defined levels of one (1) milligram per square centimeter; or five-tenths (0.5%) percent by weight.
Lead-contaminated Soil – means bare soil on residential real property and on the property of a child-occupied facility that contains lead at, or in excess of, levels identified by the U.S. EPA under TSCA, Section 403, 15 U.S.C. 2683.
Lead dust – Dust that forms when lead-based paint is dry scraped, dry sanded, or heated. Dust also forms when painted surfaces bump or rub together. Lead chips and dust can get on surfaces and objects that people touch. Settled lead dust can re-enter the air when people vacuum, sweep, or walk through it.
Lead-free – A property that is devoid of the presence of both interior and exterior lead paint.
Lead-safe housing – Housing that has been inspected by a state lead inspector and certified lead-safe by passing a dust test. (No housing built before 1950 is considered lead safe unless it has been inspected by a certified lead inspector).
Lead Safe Work Practices – a collection of “best practices” techniques, methods and processes which minimize the amount of dust and debris created during remodeling and renovation, rehabilitation or repair of pre-1978 housing.
Paint Stabilization – repairing any physical defect in the substrate of a painted surface that is causing paint deterioration, removing loose paint and other material from the surface to be treated and applying a new protective coating or paint.
Person at Risk – A child under the age of six (6) or a pregnant woman who resides or regularly spends at least twenty-four (24) hours per week in an affected property.
Rental Property Owner – Any person or entity that has legal title to housing, including individuals, partnerships, corporations, government agencies, and nonprofit organizations who own and rent affected properties.
Risk Assessment – An on-site investigation of housing to determine if lead hazards are present and how they can be controlled.
Risk Assessor – A certified individual who has completed training with an accredited training program and has been certified to perform a risk assessment.
Standard Dust Test – The most common method for dust collection is a surface wipe sample. Usually baby wipes or wet wipes are used to collect dust from the property. After sampling, the wipe is placed in a container and sent to a laboratory for analysis.
ug/dL – Short for micrograms per deciliter. The measurement is used to express how much lead is in the blood.
Wet scraping – A process used to remove loose or chipping paint. The paint is wet misted before being scraped to keep dust levels down.
