SECTION 2: Hazards identification

Hazard statements

Xn" - Harmful R20/22: Harmful by inhalation and if swallowed. R36/38: Irritating to eyes and skin. R40: Limited evidence of a carcinogenic effect. R43: May cause sensitisation by skin contact. R48/20 Harmful danger of serious damage to health by prolonged exposure through inhalation EMERGENCY OVERVIEW PHYSICAL APPEARANCE: Brown viscous material IMMEDIATE CONCERNS Warning! Product contains fluorides In use above 500oC [930oF] in the presence of water vapor, hydrogen fluoride gas is evolved. Hydrogen fluoride gas can cause irritation to the respiratory tract, and delayed burns to the eyes and skin. It can also cause fluid in the lungs [pulmonary edema], and death. Avoid contact with skin, eyes, and inhalation of vapors. Warning! This product contains Nickel May cause skin irritation, dermatitis or sensitization. Prolonged or repeated inhalation may be harmful. Under special conditions nickel can react with carbon monoxide in a reducing atmosphere to form nickel carbonyl Ni[CO]4, an extremely toxic gas. Fumes from the soldering/brazing process are irritating to the eyes and respiratory system. Hot metal can cause eye and skin burns. Avoid breathing fumes from the soldering/brazing process. Use only with adequate ventilation.

Potential health effects

EYES: Can cause severe irritation and abrasion. [Contains metal powder and fluoride salts.] SKIN Flux ingredient(s) Skin contact may cause severe irritation, burns. Prolonged skin contact may lead to symptoms similar to ingestion. Solvent Skin contact may cause irritation, dermatitis Alloy: Hot molten metal may cause burns to the skin. Wear protective equipment when working with molten metal. Copper: Skin contact may cause irritation and dermatitis. Nickel: Metallic nickel can cause nickel sensitivity resulting in an allergic reaction such as a skin rash. INGESTION Flux ingredient(s) Fluorides Can severely irritate and burn the mouth, throat and stomach. Symptoms include salivation, nausea, vomiting, diarrhea, abdominal pain, and coma. Ingestion may cause systemic poisoning. Silver: Prolonged ingestion of silver compounds may cause a permanent bluish discoloration of the skin, eyes, and mucous membranes. Copper: Ingestion may cause nausea, vomiting, diarrhea. Nickel: Ingestion may cause nausea, vomiting, dizziness, gastrointestinal discomfort, headache. Zinc: Ingestion of soluble salts of this material may cause abdominal irritation resulting in nausea and vomiting. INHALATION Flux ingredient(s) Fluoride fume can cause respiratory irritation and pulmonary edema. Binder If inhaled, may cause coughing, sneezing, adverse lung effects, irritation of the respiratory tract. Silver: Prolonged inhalation of silver compounds may cause a permanent bluish discoloration of the skin, eyes, and mucous membranes. Copper If inhaled, may cause sneezing, nausea, weakness, fever. Fumes from heating may cause metal fume fever Zinc: This material is relatively non-toxic to humans by inhalation. However, acute overexposure to zinc oxide fume may cause metal fume fever, characterized by flu-like symptoms such as chills, fever, nausea and vomiting. Nickel: If inhaled, may cause headache, coughing, dizziness, and difficulty breathing. SIGNS AND SYMPTOMS OF OVEREXPOSURE ACUTE TOXICITY: Acute overexposure to copper fume and/or zinc oxide fume evolved from heating this product may cause metal fume fever, characterized by flu-like symptoms such as chills, fever, nausea and vomiting. Hypersensitivity to nickel is common and can cause allergic contact dermatitis, pulmonary asthma, or conjunctivitis. The most common effect resulting from exposure is the development of 'nickel itch'. It occurs primarily in persons doing nickel-plating and is most frequent under conditions of high temperature and humidity.

Potential chronic health

Flux ingredient(s) Repeated exposure to fluoride containing dust can result in embrittlement and decalcification of bones and increased calcification of ligaments and vertebrae [fluorosis], stiffness and limitation of motion can result. Symptoms of fluorosis include brittle bones, weight loss, anemia, calcified ligaments, general ill health, joint stiffness, mottling of teeth, and bone damage [osteosclerosis]. Solvent Prolonged or repeated exposure to the material may cause dermatitis, kidney damage Silver: Chronic exposure may produce argyria, a permanent blue-gray discoloration of the skin, eyes, mucous membranes and respiratory tract. Skin contact with silver powder produces localized irritation and/or argyria. Copper Prolonged or repeated exposure to the metal may cause skin and hair discoloration, skin irritation, dermatitis, runny nose, irritation of the mucous membranes. Repeated ingestion may cause: damage to liver, kidneys. Repeated inhalation may cause chronic respiratory disease. Nickel: Hypersensitivity to nickel is common and can cause allergic contact dermatitis, pulmonary asthma, conjunctivitis and inflammatory reactions. Repeated over-exposure via inhalation of fumes evolved from heating of this product can have adverse effects on the pulmonary system [edema and/or emphysema]. CARCINOGENICITY: Ingredient(s) of this product are listed as carcinogens. See Section 11 for further details. MUTAGENICITY: Not identified as a Mutagen. REPRODUCTIVE TOXICITY REPRODUCTIVE EFFECTS: Not identified as a reproductive toxin.

Medical Conditions Generally Aggravated by Exposure

May aggravate pre-existing skin conditions, respiratory disorders, liver disorders, kidney disorders, pulmonary function, Wilson's disease, GI tract. ROUTES OF ENTRY Potential routes of entry include eye contact, skin contact, inhalation of metallic fume and decomposition products from heating this material during the soldering/brazing process. TARGET ORGAN STATEMENT Affected target organs eyes, skin, central nervous system, respiratory system, bones (fluorosis), calcification of ligaments and vertebrae, teeth, liver, kidneys, mucous membranes, GI tract, conjunctiva. SENSITIZATION: Metallic nickel can cause nickel sensitivity resulting in an allergic reaction such as a skin rash.

Health hazards

Fluorides can cause eye, skin, and respiratory tract irritation. Overexposure to fluoride dust over prolonged periods can result in fluoride deposition in bones and cartilage as evidenced by X-ray changes [fluorosis] which may be accompanied by stiffness of joints. In use above 500oC [930oF] in the presence of water vapor, hydrogen fluoride gas is evolved. Hydrogen fluoride gas can cause irritation to the respiratory tract, and delayed burns to the eyes and skin. It can also cause fluid in the lungs [pulmonary edema], and death.
