1205 Alloy Powder

SECTION 2: Hazards identification

OSHA EMERGENCY OVERVIEW PHYSICAL APPEARANCE: Fine powder, metallic gold in color. IMMEDIATE CONCERNS: 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: Dust may cause physical eye irritation. SKIN: May cause skin irritation. Hot molten metal may cause burns to the skin. Wear protective equipment when working with molten metal. INGESTION 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 Zinc Ingestion of soluble salts of this material may cause abdominal irritation resulting in nausea and vomiting. INHALATION 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. Tin: No adverse effects expected. Inhalation of dust may cause mechanical irritation. SIGNS AND SYMPTOMS OF OVEREXPOSURE ACUTE TOXICITY: Acute overexposure to zinc oxide fume evolved from heating this product may cause metal fume fever, 1205 Page 2 of 6 characterized by flu-like symptoms such as chills, fever, nausea and vomiting.

Potential chronic health

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 produce localized irritation and/or argyria. Copper: Prolonged or repeated exposure to the material 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. Tin Prolonged or repeated exposure to the material may cause benign pneumoconiosis, producing distinctive changes in the lungs with no apparent disability or complications. CARCINOGENICITY: The materials used to formulate this product are not listed as a carcinogen by NTP, IARC, or OSHA.

Medical Conditions Generally Aggravated by Exposure

Persons with pre-existing disorders of the liver, kidney, pulmonary function or having Wilson's disease may be more susceptible to the effects of this material. ROUTES OF ENTRY Potential routes of entry include eye contact, skin contact, inhalation of metallic dusts or fume evolved from heating of this product.
