These small quantities (less than 0 . 1%) frequently referred to as "trace" or "residual' elements, generally originate in the raw material used. Theses elements may include, but are not limited to the following: Arsenic, Cadmium, Nitrogen, and Zirconium. Section 4 First Aid Measures Description of necessary first aid measures: • Inhalation : If large amounts of dust, fumes, and/or particulates are generated, move person to fresh air, If symptoms develop, seek medical attention, • Eye contact: If eyes contact with dust or particulates, flush eyes with running water for 15 minutes. Eye injuries from solid particles should be treated by a physician immediately. • Skin contact: If skin contact with dusts or powders, wash immediately with soap and water. Any cuts or abrasions should be treated promptly with thorough cleansing of the affected area. • Ingestion : If ingested no first aid needed, however if symptoms develop, seek immediate medical attention. For Ingestion of dusts or powder : If swallowed, call a poison center or doctor/physician if you feel unwell. Rinse mouth thorough. Important acute and chronic symptoms /effects : Stainless steel products in their usual physical form do not present an inhalation, ingestion or contact hazard. However, operations such as burning, welding, sawing, brazing, machining and grinding may result in the following effects if exposures exceed recommended limits as listed in Section 8 - Exposure Controls/Personal Protection, Acute Effects : • Inhalation : Excessive exposure to high concentrations of dust may cause irritation to the eyes, skin and mucous membranes of the upper respiratory tract. Excessive inhalation of fumes of freshly formed metal oxide particles sized below 1 . 5 microns and usually between 0 .02 - 0 .05 microns from many metals can produce an acute reaction known as " metal fume fever" . Symptoms consist of chills and fever (very similar to and easily mistaken with flu symptoms), metallic taste in the mouth, dryness and irritation of the throat followed by weakness and muscle pain. The symptoms come on in a few hours after excessive exposures and usually last for 12 - 48 hours. Long-term effects from metal fume fever have not been noticed. Freshly formed oxide fumes of manganese have been associated with causing metal fume fever. Inhalation of chromium compounds may cause upper respiratory tract irritation. Inhalation of silica dusts may result in silicosis. Nickel compounds are respiratory tract irritants, • Eye : Excessive exposure to high concentrations of dust may cause irritation and/or sensitization to the eyes. Particles of iron or iron compounds, which become imbedded in the eye, may cause rust stains unless removed promptly. Molybdenum compounds are eye irritants. • Skin : Repeated or prolonged contact with dusts may cause skin irritation or sensitization, possibly leading to dermatitis and allergic sensitization. Molybdenum compounds are skin irritants. • Ingestion: Ingestion of harmful amounts of this product as distributed is unlikely due to its solid insoluble form. Ingestion of dust may cause nausea or vomiting. Chronic Effects by components : • Iron (Iron Oxide) : Chronic inhalation of excessive concentrations of iron oxide fumes or dusts may result in the development of a benign pneumoconiosis, called siderosis, which is observable as an X-ray change. No physical impairment of lung function has been associated with siderosis. Inhalation of excessive concentrations of ferric oxide may enhance the risk of lung cancer development in workers exposed to pulmonary carcinogens. Iron oxide is listed as a Group 3 (not classifiable carcinogen by IARC. Rev. Date May - 2015 2 PSM -SDS-SS f i
