Lead Paint Removal >> Lead Paint Abatement Contractors In Massachusetts

Lead paint removal, 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 Lead Paint Abatement Contractors In Massachusetts housing units in the country. Property owners should assume that 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 Lead Paint Abatement Contractors In Massachusetts methods has advantages and disadvantages: 

Testing Process Advantages Disadvantages--Spot chemical test, 8% sodium sulfide solution--Easy to use--Readily available in kits from many paint stores--Results are easily visible: paint that darkens usually contains lead--Cannot quantify the amounts of lead present--Cannot be used on dark colors where color changes may be imperceptible--False Lead Paint Abatement Contractors In Massachusetts 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 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 Lead Paint Abatement Contractors In Massachusetts 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 abatement procedures. Some Lead Paint Abatement Contractors In Massachusetts 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 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 Lead Paint Abatement Contractors In Massachusetts amounts of lead dust. 

Homeowners who undertake such 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: 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, Lead Paint Abatement Contractors In Massachusetts may be affected.

Evaluation of the relative historic significance of the affected features, by themselves and in context of the overall property. Evaluation of the necessity of abatement, Lead Paint Abatement Contractors In Massachusetts 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 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, by thorough Lead Paint Abatement Contractors In Massachusetts 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, and abatement requirements differ according to the use to which an old building is placed. A treatment that may be acceptable for one old Lead Paint Abatement Contractors In Massachusetts 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 district in which it is located. Recommended Abatement Priorities Complete Lead Paint Abatement Contractors In Massachusetts removal of features affected with lead paint is not always required. 

Lead, like asbestos and rattlesnakes, 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, Lead Paint Abatement Contractors In Massachusetts it may be safer in some cases to leave intact paint layers undisturbed. 

Flat painted surfaces pose much less danger than protruding, irregular Lead Paint Abatement Contractors In Massachusetts surfaces. Floors, most wainscots, and 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. 

If the need for lead paint abatement can be clearly demonstrated, and if the contaminated features and finishes are important Lead Paint Abatement Contractors In Massachusetts to the preservation of the property's historic character, the following priorities should be used. These are ranked on the principle of minimal intervention. Removal of lead from architectural features in situ, using safe measures that do not put excessive amounts of lead dust or residue into the environment.

Appropriate measures are evaluated below. Removal of architectural features from the building and controlled Lead Paint Abatement Contractors In Massachusetts removal of lead paint off-site; followed by replacement of the treated features in their original locations. Containment or encapsulation of features using non-destructive methods. When lead based paint is present on flat plaster walls and ceilings, these features can be encapsulated with dry wall or sheetrock. 

When lead-based paint is present on simple floors, sealing the surface and covering the floors with carpeting that meets abatement criteria may be considered appropriate from a Lead Paint Abatement Contractors In Massachusetts preservation perspective. Conventional wallpaper and new layers of paint have little or no encapsulation value. Removal of contaminated features and replacement with in-kind replications. 

If permanent removal of contaminated features is unavoidable, in-kind replication may be an acceptable alternative. Such an approach should be considered only when the loss of the features would not seriously undermine the integrity of the historic Lead Paint Abatement Contractors In Massachusetts property. 

If contaminated features and finishes are determined to be not important for the preservation of the property's historic character, removal of contaminated features without replacement in kind may be appropriate. Recommended Procedures for Removing Lead Paint on Historic Surfaces Removal of lead-based paint from significant historic features should only be considered if it is demonstrated that the features are contaminated above regulated levels, and that the Lead Paint Abatement Contractors In Massachusetts contamination is reasonably accessible to building occupants. 

The cheapest methods for removing lead-based paint are usually not appropriate for older buildings. Poorly chosen paint removal methods can lead to a loss of significant architectural features, damage to wood and plaster, or loss of early paint schemes. Speed is no substitute for quality. The Lead Paint Abatement Contractors In Massachusetts dangers associated with removing lead-based paint demand careful planning and execution. 

The following procedures are recommended when on-site abatement procedures are indicated. 1. Restrict entry to the Lead Paint Abatement Contractors In Massachusetts work area. Only workers directly involved in the project should enter the work area. Young children and pregnant women must stay out of the work area until cleanup has been completed. 

Warning signs should be posted outside all entrances and exits to the Lead Paint Abatement Contractors In Massachusetts work area. For any project involving abatement of lead hazards in a residence, or involving removal of more than a very limited amount of lead paint, it is advised that all residents of that home, including pets, find other housing. Residents are advised stay out of the building until cleanup has been completed.
