Lead Paint Removal >> The Hazards Of Dealing With Lead Paint

Lead accumulates in the body following exposure. Lead stays in the blood for several months, and it can be stored in the bone for many decades. Lead poisoning (plumbism) usually results from many small exposures over a period of weeks or years. The brain and nervous system are particularly The Hazards Of Dealing With Lead Paint susceptible. 

It has long been known that high levels of lead exposure can cause serious disability or death. Lead poisoning interferes with the formation of blood cells, which may cause anemia. Lead can also damage the kidneys, digestive system, reproductive system, and The Hazards Of Dealing With Lead Paint other organs. More recent research has focused on the toxic effects of low level exposure. 

There is no established safe level of lead in the human body. No level of exposure can be regarded as free from potential harm. Low level exposure can damage hearing, learning ability, and The Hazards Of Dealing With Lead Paint coordination. Children less than six years of age are of special concern because their developing brains and bodies can easily be damaged by lead. 

It is common for young children to put everything,including hands, pacifiers, and toys, into their mouths. Anything which contains lead, The Hazards Of Dealing With Lead Paint from small dust particles to large paint chips, can cause harm if swallowed. Lead poisoning commonly contributes to problems which may be permanent in young children. 

Learning disabilities,behavior abnormalities, attention deficit problems, and insomnia are common symptoms. Some The Hazards Of Dealing With Lead Paint studies estimate that one out of every six children in the United States has some degree of lead poisoning. Symptoms of lead poisoning can go unnoticed. Blood tests are very important to detect lead poisoning early, and they should be part of the routine health care for all young children.

Lead, even at very low levels, can have toxic effects on unborn children. Infants born with only slightly elevated blood lead levels have been found to have developmental problems. If detected early, lead poisoning can be treated. In extreme cases, The Hazards Of Dealing With Lead Paint a medical procedure called chelation therapy may be initiated to help expel toxic levels of lead from the blood system. 

Testing for Lead on Painted Surfaces The National Institute of Building Sciences has estimated that dangerous levels of lead based paint exist in 42 million of the estimated 80 million housing The Hazards Of Dealing With Lead Paint units in the country. Property owners should assume that most older paints contain lead. The presence of lead can be confirmed by qualified inspectors or laboratories. 

Two processes are used to test for lead on site: the application of sodium sulfide to the painted surface, and the use of a mobile X-ray fluorescence analyzer. Paint samples can also be sent to commercial laboratories for analysis. Each of these The Hazards Of Dealing With Lead Paint methods has advantages and disadvantages: Testing Process 

Advantages--Spot chemical test, 8%sodium sulfide solution--Easy to use--Readily available in kits from many The Hazards Of Dealing With Lead Paint paint stores--Results are easily visible: paint that darkens usually contains lead Disadvantages--Cannot quantify the amounts of lead present--Cannot be used on dark colors where color changes may be imperceptible--

False readings can sometimes occur--Has a limited shelf life--Mobile X-ray fluorescence analyzer--Gives digital readouts quickly--Readouts are accurate--Gives lead measurements per The Hazards Of Dealing With Lead Paint unit area--Seldom available to individual because of high cost--Cannot be used in inaccessible spaces--Cannot measure levels of lead dust--

Analysis of samples by commercial analytical laboratory--Gives the most accurate results--Can give percentage lead by weight--Can verify other methods--Laboratory work can be expensive--Results may not be available immediately The mere presence of lead-based paint is not sufficient cause for The Hazards Of Dealing With Lead Paint abatement procedures.

Some contractors and review authorities have acted on the assumption that any and all features that have lead-based paint must be removed. This is an expensive and The Hazards Of Dealing With Lead Paint destructive approach. Not only does this presumption lead to unnecessary loss of historic architectural elements, it has great potential to accelerate the dissemination of lead dust into the environment. 

Paint removal projects tend to generate tremendous amounts of lead dust. Homeowners who undertake such The Hazards Of Dealing With Lead Paint projects should be aware that they may be contaminating their environment. Appropriate follow-up planning to deal with lead-contaminated features should include these steps: 1. Specification of which elements are affected. 

Not all rooms in a building, nor even all features in a space that contains some lead-based paint, may be affected.2. Evaluation of the relative historic significance of the affected features, The Hazards Of Dealing With Lead Paint by themselves and in context of the overall property. 3. Evaluation of the necessity of abatement, in consideration of the location of the affected features, the significance of the affected features, and the proposed use of the building and the space.

Abatement Abatement means the elimination of exposure to lead-based substances that may result in lead toxicity or poisoning, by the removal or encapsulation of lead-containing substances, The Hazards Of Dealing With Lead Paint by thorough cleanup procedures, and by post-cleanup treatment of surfaces.The Lead Poisoning Prevent Act of 1971 is the only Federal law to date that applies to lead-based paint. 

It is limited to projects involving Federally-owned or assisted housing. State and local regulations vary, The Hazards Of Dealing With Lead Paint and abatement requirements differ according to the use to which an old building is placed. A treatment that may be acceptable for one old building may not be appropriate in another. For projects seeking federal tax benefits or for projects involving federal financing or permits.

The Secretary of the Interior's Standards for Rehabilitation take precedence over other regulations and codes in determining whether rehabilitation procedures are consistent with the historic character of the property and, where applicable, The Hazards Of Dealing With Lead Paint the district in which it is located. Recommended Abatement Priorities 

Complete removal of features affected with lead paint is not always required. Lead, like asbestos and rattlesnakes, The Hazards Of Dealing With Lead Paint is most dangerous when it is disturbed. Careless abatement procedures will probably increase the level of lead contamination in a building. Unless meticulous masking and clean-up methods are used, it may be safer in some cases to leave intact paint layers undisturbed.

Flat painted surfaces pose much less danger than protruding, irregular surfaces. Floors, most wainscots, and The Hazards Of Dealing With Lead Paint baseboards, for example, usually do not require abatement if the paint is intact and non-flaking. Intact painted surfaces on fixed window sash, upper members of window or door frames, and ceilings usually do not require treatment.
