Lead, widely used for building construction and as a component of paint, is a heavy metal, which, like mercury, is a potent neurotoxin which accumulates in soft tissue and bone. As a poison, there are a number of applications of lead that we now consider to be hazardous to human health. While sale of lead paint to consumers is now largely discontinued, Though it remains available for use on bridges, ships and many other metal constructions. Many structures still contain lead paint as well as lead in glazing, caulk, and solder.
The wide use of lead in industry, including the production of batteries, tile, ammunition and radiation shielding devices is another means of exposure.
Criterion conducts lead and metals surveys to evaluate the existance and danger associated with lead and heavy metals presence in buildings and in the workplace. Our highly trained staff and state of the art technology provide accurate and reliable answers to inform you of conditions at your facility.
We also provide contractor abatement training,including the NEW Lead Rennovator Training, vital for all contractors under the NEW EPA regulations, set to take effect April 10, 2010 (see training page for details)
