Get lead information about tri sodium phosphate

1. All phosphates, including tri sodium phosphate (TSP), are so damaging to the environment, particularly lakes and rivers, that more than 19 states and several counties in 15 other states, limit the phosphorous content of household laundry products to 0.5% (this is assumed to be a virtual ban). The Material Safety Data Sheet (MSDS) from Rhone-Poulenc¹ states; "Do not flush material into public sewer system or any water way."²

2. Tri sodium phosphate leaves a phosphate film on surfaces that if not thoroughly rinsed will cause adhesion failure and/or blistering of new paint or encapsulant. Experiences with workers performing lead abatement activities in residential properties suggest that it is very difficult to have them clean every surface. Imagine also requiring the complete rinsing at all surfaces to remove the difficult to rinse phosphate residue so that new paint or encapsulant will adhere.

3. Phosphate mixed with lead can form a compound known as lead-phosphate --Pb₃(PO₄)₂. Any of the many slightly soluble lead compounds can react with phosphate in solution to form lead-phosphate which can precipitate out of solution as a residue. The Merck Index 11^th edition states about lead-phosphate; "This substance may reasonably be anticipated to be a carcinogen."³

4. Skin, eye or respiratory contact with tri sodium phosphate is hazardous. The hazardous material identification system rates hazards as follows:

Tri sodium phosphate, TSP or tri-basic, is rated 3 high/serious (sodium phosphate anhydrous is also rated 3, high/serious).

The section "Effects of single overexposure" on the sodium phosphate anhydrous MSDS reads in its entirety:

5. The MSDS sheet for Cascade automatic dishwashing detergent states that the product contains sodium phosphates. The MSDS assumes "normal handling procedures." In a call to Procter and Gamble's consumer service number on 10/23/96 about Cascade, the consumer service technician stated that P&G "Definitely does not recommend the use of Cascade dish-washing detergent in the cleaning of a home or any use outside its intended use in a dish-washer receptacle or for soaking dishes."

6. Based on the experience of many contractors, and a study by the Canada Mortgage and Housing Corporation, using phosphates or tri sodium phosphate for lead clean-up is not necessary. In fact, using a lead-specific cleaner proved more effective.

Ledizolv® is THE lead-specific cleaner scientifically formulated for use in the clean-up and control of lead dust hazards. It's a perfect solution for people living or working in lead paint poisoned environments; contractors working on renovation, maintenance, or abatement; and government and health agencies working to solve lead problems by removing lead paint and dust.

LSZ, Inc., devoted 2 ½ years and substantial resources for the development of this product. The focus of our lead information research and development was to invent a lead-specific cleaner that would achieve maximum lead dust removal, while at the same time having excellent functional, environmental and health safety characteristics.

The result of our R&D is Ledizolv® -- a lead-specific, phosphate-free, lead-dissolving detergent that helps prevent lead paint poisoning.

The lead-specific nature of Ledizolv® has been proven in thousands of clearance tests and extensive field studies. These tests have shown Ledizolv® to be a superior and more appropriate cleaner in removing lead paint and lead contaminated dust (LCD) than tri sodium phosphate (TSP) and other phosphate-containing and/or multi-purpose cleaners.

Precaution:	Persons attending the patient should avoid direct contact with heavily contaminated clothing and vomitus. Wear impervious gloves while decontaminating skin and hair.
Swallowing:	Symptoms of swallowing are burning pain from mouth to stomach. May cause irritation or corrosion of the mouth, throat, esophagus and stomach, including blistering of the mucous membranes. Aspiration of the swallowed product or vomitus can cause severe pulmonary complications.
Skin Absorption:	No information is available regarding absorption of the product through the skin, but deep penetrating burns are caused by contact with the product.
Inhalation:	Inhalation of dust may cause irritation or burns to the nose, throat or respiratory tract, resulting in cough, chest pain and difficult breathing.
Skin Contact:	Contact with the dry solid or solutions may cause severe irritation or burns if not washed or removed from the skin promptly. Irritation is likely to be severe if the skin is moist or wet. Contact with concentrated solutions may cause severe irritation or burns depending on the concentration of the product and duration of the contact.
Eye Contact:	Contact with the dry solid or solutions may cause severe irritation or burns. The possibility of severe eye damage exists if concentrated solutions are splashed into the eyes and not promptly and properly treated.
