EverGreen uses non-destructive, non-invasive XRF technology to evaluate painted and coated surfaces for the presence of lead. Lead paint chip sampling will result in a disturbed surface that must be fixed using lead safe work practices before the inspector leaves.
What’s the difference between a Lead Inspection and a Lead Paint Risk Assessment?
A lead inspection involves the step by step / surface by surface testing of painted or coated surfaces for the presence of lead paint. The inspection report will tell you what surfaces or building components contain lead paint. That way the building owners can focus on ensuring that the paint is in good condition and does not pose a health risk, especially to small children. The report will allow the building owner to make informed decisions about renovations or window replacements.
A Lead Paint Risk Assessment is different. Let’s say you own a house or rental housing built before 1978. Chances are good that there is lead paint somewhere in the home. If the age is very old – perhaps it was built between 1900 – 1940 – you can pretty much guarantee that lead is present. A lead paint inspection would tell you where the lead is; in contrast a risk assessment will give you information about the chance that enough lead, as dust or in soil, is present to cause lead poisoning. This is especially useful if you have small children or toddlers that may come in contact with lead dust. The risk assessor will take lead dust wipes and inspect areas of the house where lead paint can be scraped or abraded by friction, like when a door shut and rubs up against the casing.
It doesn’t take much lead to cause a poisoning risk. Here’s a thought:
Take a penny. It weighs between 2.5 and 3 grams. Depends on the year the penny was minted, the newer pennies have zinc so they weigh less.
Use the 3.o grams weight. If you take that penny and pulverized it into powder, think of the powder as lead, there is enough lead to scatter 75,000 square feet up with up to 40 micrograms per square foot, which is the EPA / HUD standard for lead poisoning risk on a floor.
To sum up, that’s 37 houses with each house floor space at 2,000 square feet. So a penny size glob of lead is enough to poison 37 average houses.
