Health Effects
Enter text or highlight term...
Acute Health Effects: From MSDS
Frit is a fused silicate glass substance. The components of this glass product listed below are from the inventory of potentially hazardous substances referenced by FED/OSHA in 29 CFR 1910.1200.

Other Information
Frits are produced from the chemical reactions which occur during the high temperature smelting of various raw materials to form a molten glass. This glass is rapidly cooled and then ground to produce powdered frit. The lead listed
for this product is incorporated into the glass structure of the frit, chemically reacted in the form of silicates of other essentially insoluble complexes. Exposure to the hazardous ingredients can occur if spray mist is inhaled or glaze
ingested and the ingredient dissolves out of the glass. Because of the chemical stability of frit and its resistance to attack by acids or alkali, this is anticipated to occur very slowly. This product contains the following component(s) that require reporting under Section 313 of the Emergency Planning and Community Right-to-Know Act, also known as Title III of SARA (Superfund Amendments and Reauthorization Act), and 40 CFR Part 372:

TOXICOLOGICAL INFORMATION
Chronic Health Effects: From MSDS
Principal Routes of Absorption: Inhalation and ingestion
Effects of Overexposure: Of primary concern is chronic overexposure to lead. Initial warning properties are poor. Prolonged or repeated inhalation and/or ingestion of lead containing frit dust may result in lead poisoning, with symptoms of weight loss, stomach cramps, loss of coordination and joint and muscle pain. Lead can cause kidney damage and delayed effects involving the blood, gastrointestinal, nervous, and reproductive systems. Excessive exposure to lead dusts during pregnancy can result in neurological disorders in infants. For additional information consult OSHA lead standard 29
CFR 1910.1025.
Metal fumes and/or fluoride containing vapors from firing ma cause lung inflammation and injury in terms of hours with symptoms of chest pains, chills, cough, headache, and diarrhea.
Prolonged contact with frit dust can be very irritating to the eyes and/or skin. High dust levels can be irritating to the respiratory tract.
With adequate ventilation, dust control, and good personal hygiene, symptoms of overexposure should not occur. Advise regular medical monitoring of employees by a physician competent in industrial health.
Carcinogenicity: From MSDS
California Proposition 65:
WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

Carcinogenicity: In IARC Supplement 7, inorganic lead compounds are given a 2B rating which indicates sufficient evidence for carcinogenicity to animals and inadequate evidence for carcinogenicity to humans.
First Aid: From MSDS
Eye Contact: Flush eyes with large amounts of water until irritation subsides. Consult a physician.
Skin Contact: Wash affected skin areas thoroughly with soap and water. Consult a physician if irritation persists.
Inhalation: Move subject to fresh air; if breathing is difficult give oxygen. Consult a physician.
Ingestion: If swallowed, consult a physician. Induce vomiting if prescribed under medical supervision. Never give anything by mouth to an unconscious person.
