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:
Primary Routes of exposure: Inhalation, Skin Contact, and Ingestion
Overexposure Effects
Overexposure to cadmium by inhalation can result in a metallic taste in the mouth, headache, shortness of breath, chest pain, weakness, leg pains and fluid in the lungs. These signs and symptoms may be delayed, sometimes occurring four to eight hours following exposure. Kidney and liver damage
may also occur. Swallowing can result in severe nausea, vomiting, diarrhea, stomach cramps, salivation, headache, muscle cramps and dizziness.
Excessive ingestion of barium containing frit may cause inflammation of the gastrointestinal tract, muscular paralysis, slow pulse rate, irregular heart contractions, and low blood potassium levels.
Metal fumes from firing may cause lung inflammation and injury in terms of hours with symptoms of chest pains, chills, cough, headache, and diarrhea.
Medical Conditions Aggravated by Overexposure
Populations at increased risk to cadmium include individuals with kidney disease, genetic differences in induction of metallothionein and dietary deficiencies in metal ions and/or protein.
Chronic Health Effects: From MSDS
Long term exposure to the fumes and dust of cadmium have been associated with emphysema, bronchitis, and kidney damage. Chronic overexposure to the metal and cadmium compounds, such as cadmium oxide, cadmium sulfide, cadmium sulfate and cadmiu
Carcinogenicity: From MSDS
NIOSH (Current Intelligence Bulletin 42, September 27, 1984) recommends that cadmium and its compounds be considered as potential occupational carcinogens. In IARC Monograph 58, cadmium and its compounds are undifferentiated as Group I human carcinogens. NTP
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.
