Step Two: Before the Work Begins, Containing the Area
If you are working on a home built prior to 1978, you will want to begin your bid process by testing the surfaces in the renovation area for lead paint or varnish. If you determine through an EPA-recognized Lead Testing Kit that your worksite contains lead, you will need to secure the regulated area prior to beginning any work activities. Here is a checklist of the materials you will need to properly secure the regulated area.
Materials You Will Need
• Heavy Plastic Sheeting
• Blue Painter Tape and/or Stapler
• Warning Signage which states: Warning Lead Poison Keep Out
• Warning/Barrier Tape
• Paperwork Holder
The procedures for containing the regulated space are similar in concept for both indoors and outdoors renovations. Remember, all companies involved in the renovation need to be an EPA Certified Firm and have an EPA Lead Certified Renovator on site during their renovation activities. EPA lead certification of one firm does not provide coverage for other firms subcontracting on the same project; each firm is responsible for its own activities and certifications.
Indoors Renovations:
• Remove all furniture and appliances possible prior to containment. Those items that cannot be removed should be encapsulated in heavy plastic or poly furniture covers.
• Close and seal all HVAC vents leading into and out of the worksite
• Turn off all HVAC systems during renovation whenever possible
• Seal all doors, windows and openings with heavy plastic and tape or staples
• Cover the floors with heavy plastic sheeting
• Place warning signage at all entrances to the worksite.
• Assign separate pathways and entrances to the home for residents and workers to enter and leave the site while working.
Outdoors Renovations:
• Seal all windows and doorways around the worksite
• Cover the ground and landscaping with heavy plastic
• Remove children’s playground equipment if possible, or cover with heavy plastic
• Mark-off work area with warning barrier tape
Be sure the residents understand the importance of respecting the barriers once work has begun. Curious homeowners may be tempted to sneak a peek at your progress, and in the process contaminate other areas of the residence. Once work has begun, homeowners wanting to check progress should be accompanied by one of your workers, someone who can help them to suit-up and decontaminate themselves before leaving the workspace. We will cover protective gear and clothing in Step 3 of our series, Gearing Up With Lead-Safe Protective Gear.

LEAD PAINT…THE ALLIGATOR IN MY HOME!
If My Home Could Contain Lead Paint, How Do I Test for It?
EPA RRP Lead-Based Paint Certification and Safety Laws
As with any new program, most people, home owners and contractors alike, first hearing about the EPA’s Lead Paint Certification program are very skeptical. Yet we find, when they REALLY investigate the issue, they realize that the program is needed to bring awareness those individuals who might inadvertently produce lead poisoning exposure. Today, in 2010/2011, many people, contactors included, are initially caught off guard and are unaware of the very real health hazards associated with paint containing lead when it’s disrupted. The bottom line, Lead-based paint is hazardous to your health.
LEAD PAINT IS LIKE AN ALLIGATOR!
How many people would jump into a neighborhood pond if they knew of an alligator living in it? Yet, many people have jumped into such a pond or have had their dogs drinking water from such a pond, only to find out after it’s too late, that an alligator was living in it. In the world of lead paint…the alligator is paint containing lead, and the pond is a house built prior to 1978. Today, 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.
How are people exposed to lead from paint?
Contractors and or individuals involved in home renovation activities can generate lead dust by sanding lead-based paint or by scraping or heating lead-based paint. Eating paint chips is one way young children are exposed to lead. This 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. Lead dust can settle on floors, walls, and furniture. Under these conditions, children can ingest lead dust from hand-to-mouth contact or from food. Settled lead dust can re-enter the air through cleaning, such as sweeping or vacuuming, or by movement of people throughout the house.
How much lead does it take to get lead poisoning?
Only about 10 micrograms per deciliter of blood. What does that mean?
A deciliter is about 1/2 of a cup.
◦A packet of sweetener is roughly one gram.
◦There are one million micrograms in a gram.
◦So, divide the stuff from one packet into one million piles. (Pretend!)
◦Now, discard 999,990 of those "piles."
◦Take the remaining 10 piles and mix them into half a cup of liquid.
Now….that’s not much! Microscopic levels of lead metal can impair the health of a human, especially a young developing child.
Q. So…how do you test for Lead-Based Paint and Lead Dust?
A. The EPA Lead Abatement Certification program offers three lead hazard assessment methods available to homeowners:
Lead-Based Paint Inspection, Risk Assessment and a Lead Hazard Screen. The EPA strongly recommends that you have the testing performed by an EPA RRP Certified Professional. Certified Inspectors may perform Lead-Based Paint Inspections, and Certified Risk Assessors can perform both Lead Risk Assessments as well as Lead Hazard Screens.
Lead-Based Paint Inspection: Generally recommended prior to beginning a renovation in a home built prior to 1978. During the inspection all painted surfaces in the home including varnishes and stains are inventoried and inspected for the presence of lead-based paint. Furniture, dust and soil are not typically tested during an inspection. When the report has been completed, you should have an inventory of all surfaces tested and whether the surfaces contain lead.
Risk Assessment: The lead risk assessment is the most rigorous testing method. This method is highly recommended for those who suspect or have confirmed lead poisoning in family members. Not only are all deteriorated paint surfaces covered in the Inspection reviewed, but dust from children’s rooms, hallways and play areas are tested in addition to soil from children’s play areas. In the event furniture, window sills or molding show bite marks, these surfaces may be tested as well.
Lead Hazard Screening: Recommended for homes and facilities with a low chance of contamination. The Lead Hazard Screening is a scaled down version of the Risk Assessment. Typically, deteriorated paint surfaces are tested, two samples of dust are collected (windows and floors) and soil will not be tested unless there is evidence of paint chips in the soil. A report that shows substantial risks, may require a follow-up with a full-blown Risk Assessment.
Q. How are the surfaces tested?
A. Two methods of Lead-Based Paint Testing are recognized by the EPA:
Portable X-Ray Fluorescence (XRF) analyzers and paint chip sampling which is analyzed by a laboratory recognized by EPA’s National Lead Laboratory Accreditation Program.
Portable X-Ray Fluorescence Analyzers (XRFs) A portable XRF measures lead in paint, usually without damaging the paint. In some instances, the material beneath the paint or curves in paint chips on deteriorated surfaces can affect the lead level readings. In these instances the paint must be removed, and the underlying surface is tested to create a baseline for the painted surface being tested. This is the fastest method for delivering results, although in instances where the testing is inconclusive, paint chip samples will need to be delivered to a laboratory for further testing.
Paint Chip Sampling & Lab Analysis: By using a chisel or scraper, one to four square inches of all layers of paint are removed. Generally, a small layer of the underlying surface (wood, plaster or concrete) is removed with the sample. Following removal of the test material, the surface is repainted to prevent contamination for exposed lead surfaces. The samples are then sent to an EPA NLLAP laboratory for testing. This is the most conclusive method for testing for lead-based paint.
Keep in mind, if your home was built before 1978, and you are planning on renting or selling it, the EPA requires that you provide the test results to your buyers or renters.

Lead Poisoning: Its Symptoms and Treatment
When Does Lead Poisoning Occur and What Are the Symptoms?
Lead poisoning occurs when lead builds up in the body, often over a period of months or years. Even small amounts of lead can cause serious health problems. Children under the age of 6 are especially vulnerable to lead poisoning, which can severely affect mental and physical development. At very high levels, lead poisoning can be fatal.Lead-based paint and lead-contaminated dust in older buildings are the most common sources of lead poisoning in children. Other sources of lead poisoning include contaminated air, water, soil, and some toys and cosmetics.
The signs and symptoms of lead poisoning in children may include:
- Irritability
- Loss of appetite
- Weight loss
- Sluggishness and fatigue
- Abdominal pain
- Vomiting
- Constipation
- Unusual paleness from anemia
- Learning difficulties
Lead Exposure symptoms in newborns
Babies in the womb who are exposed to lead through their mothers may have:- Learning difficulties
- Slowed growth
Lead Exposure symptoms in adults
Although children are primarily at risk, lead poisoning is also dangerous for adults. Even exposure to amounts of lead too low to cause symptoms in the short term may increase the risk of high blood pressure and mental decline in the future.Symptoms in adults may include:
- Pain, numbness or tingling of the extremities
- Muscular weakness
- Headache
- Abdominal pain
- Memory loss
- Mood disorders
- Reduced sperm count, abnormal sperm
- Miscarriage or premature birth in pregnant women
- Fatigue
Treatment Options for Lead Poisoning:
Treatment for lead poisoning is based on a combination of factors including nutrition and removal of the source of contaimination. In most instances, these measures will be sufficient to reduce lead levels in the body.- Removal of lead paint dust and lead chips should be performed by an EPA certified lead abatement professional. Special lead containment procedures are required during repair and renovation as well as prescribed clean-up procedures to prevent further contamination of the site.
- Nutrional support includes adequate amounts of vitamins and minerals such as calcium, iron, and vitamin C. Studies find that those who eat nutritious diets rich in vitamins and minerals are less likely to absorb lead.
- If removing the source of lead and improved nutrition do not reduce blood lead levels, or in instances where the blood lead level is initially very high, chelation therapy may be required. Through chelation therapy, agents that cause metals like lead to bind to them are introduced to the system. As heavy metals like lead bind to the agents they are eliminated from the body through urine. Since chelating agents increase the absorption of metals including lead, it is essential that prior to treatment all sources of lead exposure be removed.
- If blood levels for lead do not lower with the above treatments, it is suggested that you recheck the home or building for other sources of lead contamination. Certified lead inspectors can help determine if a contamination site has been overlooked.

The new EPA RRP Lead Safety Rule - Myth, Mania or Material Risk?
Many of our students enter the new EPA Lead Paint Certification classes skeptical of the real risks that might be involved in working on lead-based paint contaminated renovations. After all, US regulations discontinued its sale after 1978. Students question whether the new regulations will merely hinder their ability to get the job done.
While contamination levels have dropped since the 1960’s, the CDC estimates that approximately 250,000 U.S. children aged 1-5 years have blood lead levels greater than 10 micrograms of lead per deciliter of blood, the level at which CDC recommends public health actions be initiated. The Ohio ABLES Registry reports that 14% of adults age 16-80 tested for elevated lead levels had levels greater than 10 micrograms of lead per deciliter of blood. Elevated contamination levels were most likely to be reported for individuals in the age range of 40-64. It is assumed that this greater risk is due to the fact that these individuals are more likely to be working fulltime, thus increasing their risk of exposure.
Lead causes long term nervous system damage, stunted growth, delayed development, and emotional issues in children and adults. It has been known to cause kidney damage and can affect most organ systems in the body. As a danger to adults, it can cause reproductive problems for both men and women. Lead paint is particularly treacherous because it tastes sweet, therefore encouraging children to put lead chips and toys with lead dust in their mouth.
One myth related to lead-based paint is that children must eat leaded paint chips to develop lead poisoning, when in fact the most common exposure to children occurs through ingestion of lead dust from normal hand-to-mouth contact when they swallow lead dust dislodged from deteriorated paint or leaded dust generated during contractor repair work, remodeling or paint surface preparation work.
Much like Asbestos and second hand smoke, lead dust is an insidious contaminant that is not easily eliminated from the body by normal processes. Given that lead dust is portable and can easily contaminate ventilation systems, vehicles and worker’s clothing, the EPA’s guidelines for lead safety, containment and protective gear are meaningful and necessary. To learn more about the guidelines and learn how to get the lead out right, click on the links to the EPA’s RRP website. If you are interested in learning more about the curriculum and exam necessary for certification check out our website at www.leadpaintremovaltraining.com. In my next post, I’ll go over the specifics of lead poisoning: its symptoms in children and adults as well as treatment options.
