Lead Paint Hazards

The most common source of lead poisoning is lead-contaminated dust (LCD). This dust can be so fine that it cannot be seen by the naked eye. Dusts can have thousands of parts per million lead by weight. The high concentrations of lead in LCD means that even tiny quantities of dust exposure can result in a very high lead intake. The current government standards for safe levels of lead-contaminated dust in housing are 100 µg/ft2 on floors; 500 µg/ft2 on window sills; and 800 µg/ft2 on window wells. Some experts believe these levels are too high and should be lowered.

 

Why Use Lead-Specific Detergents for Lead Removal?

Lead compounds in lead-contaminated dust (LCD) are found in a wide range of physical and chemical forms. Some household LCD contains lead compounds from lead paint hazards. Household LCD also can come from soil residues that include lead compounds that were used in leaded gasoline. Other lead compounds in household LCD can come from a variety of industrial, hobby, or work related activities. Different types and combinations of detergent ingredients are best for lead removal of different classes of lead compounds. Lead-specific detergents are designed to remove the wide range of lead compounds found in lead-contaminated dusts.

Household and general-purpose cleaners are designed to give a home a clean appearance, and in some cases give some germicidal or other sanitary benefits. While certain household or general-purpose cleaners may sometimes have some effectiveness against certain types of lead paint hazards, these kinds of cleaners are not designed to remove the broad range of chemical classes of lead compounds found in lead-contaminated dusts. With lead-specific detergents, it is less necessary to know the details of the lead compounds that are causing the hazard -- making lead removal simple.

Lead-specific detergent formulations are adjusted to be able to dissolve lead compounds that can be easily dissolved, as well as to chemically react with certain insoluble lead compounds to change them into a more easily cleaned form, and also to disperse other non-reactive or insoluble particulate lead. This takes the guesswork out of lead removal and leaves only one type of cleaner to use for each type of lead-contaminated dust. This can be of particular importance when cleaning very high levels of lead dust and lead paint hazards. For example, even if you suspect your hazardous lead dust comes from old lead-based paint, you would not know which of the many types of lead compounds are used in that paint. A properly formulated lead-specific detergent, such as Ledizolv® -- The Lead-Specific DetergentTM -- is effective against the wide range of lead compounds found in household LCD and is designed for lead removal down to trace levels.


Removing lead with Ledisolv 

Bottles contain Ledizolv® concentrate. Prepare a 2% solution by adding concentrated Ledizolv® to water as follows: 4 teaspoons to 1 quart of water, 1/3 cup to 1 gallon of water, one cup to 3 gallons of water, 1˝ cups to 5 gallons of water, or 1 gallon to 49 gallons of water to make a total of 50 gallons. 
Wear rubber gloves. Clean and remove all toys, rugs and belongings from the room. 
Use a HEPA vacuum (High Efficiency Particle Air Filter) or equivalent to vacuum all lead paint hazard surfaces prior to cleaning. Clean and rinse all hard surfaces by any of the means below (A, B, C or D). Work from top to the bottom starting at the farthest point from the exit of the room. Clean and rinse all walls, window components, vents, baseboards, floors, other surfaces and crevices. Clean and rinse a small area at a time before doing next area. Avoid re-contaminating clean areas while working. 

A) Container, rinse bucket and clean rags:

Wet cleaning rag with 2% solution from the container and wipe surfaces until clean. Re-fold cleaning rag periodically to expose fresh rag for cleaning. Rinse cleaning rag in clean rinse water before re-wetting in 2% solution. Change and dispose of rinse water and rags when dirty. Rinse surface with fresh water and new rag.

B) Spray bottle, rinse bucket and clean rags:

Spray 2% solution on surface and wipe off with rinse water rag. Dispose of rinse water and rags when dirty, at least once per room.

C) Mop and 2 buckets:

Use disposable string mop heads. Mop floor with 2% solution. Wring mop in clean rinse water bucket before repeating. Change and dispose of rinse water and mop heads when dirty. Do a final rinse using fresh water.

D) For porous and other hard-to-clean surfaces:

Use hot water to mix the 2% solution. Scrub surfaces. Allow 5 to 10 minutes for the solution to soak before rinsing. For best lead removal, pre-clean very dirty areas with a heavy duty or degreasing detergent.

For lead dust control, surfaces should be smooth and cleanable. Inspect and re-clean surfaces frequently. Have periodic professional lead dust sampling performed to determine cleaning frequency. Weekly cleaning may be required.

Information

Dangerous lead in dust can come from lead paint hazards, household items, lead-contaminated soil, lead pollution and lead related jobs and hobbies. The most common cause of lead poisoning is ingestion of leaded dust from deteriorated lead-based paint. Repair paint before cleaning. To learn about the steps you should take to control lead hazards call 800-532-3394. Use Ledizolv® to clean surfaces according to a hazard control specification from a lead paint hazard professional, or call 800-245-2691 to obtain a copy of the "Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing". Consult a doctor if you suspect you or a family member has been exposed to lead.
