Potential health effects

Steel products in their usual physical form do not pose a health hazard. Inhalation of metal dust and fume may result from further processing of the material by the user, particularly during welding, burning, grinding, and machining activities and should be evaluated by an industrial hygienist.

Health hazards

Individuals with chronic diseases or disorders should consult a Physician regarding workplace exposure to ingredients. The National Toxicology Program NTP and International Agency for Research on Cancer (IARC) consider (1) chromium and certain chromium compounds to be known human carcinogens, (2) nickel and certain nickel compounds to be probable human carcinogens.

Medical Conditions Generally Aggravated by Exposure

Aluminum (Al) Long-term excessive inhalation exposure to AI dusts or fumes has been associated with a fibrotic lung condition known as Shaver’s disease; however, the evidence of this is not conclusive since affected workers were exposed to other substances (such as silica) as well. Symptoms of this condition may include shortness of breath, cough, and fatigue. Cobalt (Co) Cobalt dust may cause an asthma-like disease with symptoms ranging from cough, shortness of breath and dyspnea to decreased pulmonary function, nodular fibrosis, permanent disability and death. Exposure to cobalt may cause weight loss, dermatitis, and respiratory hypersensitivity. Stainless Steel Tubing - MSDS | 2 Chromium (Cr) Chromium metal and its divalent and trivalent compounds are of low toxicity. Adverse reactions on the skin may include dermatitis for a Cr-sensitive individual. Long-term excessive inhalation exposure to ferrochromium alloys may cause lung changes in workers exposed to these alloys. Exposure to Chromium metal does not give rise to pulmonary fibrosis or pheumonconiosis. Chromium metal and trivalent chromium (Cr+3) compounds are not classifiable as human carcinogens. However, welding, torch cutting, brazing or perhaps grinding of the chromium metal in stainless steel products may generate airborne concentrations of hexavalent chromium, (Cr+6) , a confirmed human carcinogen. IARC lists hexavalent chromium compounds as Group 1 (sufficient evidence for carcinogenicity in humans). NTP lists certain hexavalent chromium compounds as Group 1 (know to be carcinogenic. The American Conference of Governmental Industrial Hygienists (ACGIH) lists hexavalent chromium compounds as A1. Columbium (Nb) Columbium interferes with calcium as an activator of enzyme systems. Copper (Cu) Excessive inhalation exposure to Cu fume may cause irritation of the eyes, nose, and throat and a flu-like illness called metal fume fever. Signs and symptoms of metal fume fever include fever, muscle aches, nausea, chill, dry throat, cough and weakness. Cu fume may also produce a metallic or sweet taste. Long-term excessive exposure to Cu fume may cause discoloration of the skin and hair. Iron (Fe) Long-term excessive inhalation exposure to iron oxide fumes or dust has been associated with a benign lung condition known as siderosis. No physical impairment of lung function has been linked to siderosis. Manganese (Mn) The dusts and fumes can act as minor irritants to the eyes and respiratory tract. Acute and long-term excessive inhalation exposures to the oxide or salts of Mn may adversely affect the central nervous system (CNS), but symptoms are more likely to occur after at least 1 or 2 years of prolonged or repeated exposures. Early symptoms may include weakness in lower extremities, sleepiness, salivation, nervousness, and apathy. In more advanced stages, severe muscular coordination, impaired speech, spastic walking, mask-like facial expression, and uncontrollable laughter may occur. Excessive inhalation exposure to manganese fumes have also been reported to result in metal fume fever, a flu-like syndrome with symptoms such as dizziness, chills, fever, headache, and nausea. An increased incidence of pneumonia, bronchitis, and inflammation of the lungs has been reported in some worker populations exposed excessively to manganese. Molybdenum (Mo) Molybdenum compounds are highly toxic. Some evidence of liver dysfunction with hyperbilirubinemia has been reported in workmen chronically exposed in a Soviet Mo-Cu plant. In addition signs of gout have been found in factory workers and among inhabitant of Mo-rich areas of Armenia. The main features were joint pains in the knees, hands, feet, articular deformities, erythema, and edema of the joint areas. May cause lung irritation. Nickel (Ni) Ni fumes and dusts are respiratory irritants and excessive exposure may cause severe inflammation of the lungs. Prolonged and repeated skin contact with nickel and its compounds may cause an allergic dermatitis. The resulting skin rash is often referred to as “nickel itch”. Ni and its compounds may also produce eye irritation, particularly on the inner surfaces of the eyelids. Studies have linked nickel and certain nickel compounds to an increased incidence of cancer of the respiratory system. Silicon (Si) Stainless Steel Tubing - MSDS | 3 This is considered to be nuisance particulate by the American Conference of Governmental Industrial Hygienists (ACGIH) Tantalum (Ta) The passivity of Tantalum metal for biological tissues has been amply demonstrated by its longtime use in surgical procedures both in animals and man. No significant toxic effects have been associated with tantalum. Titanium (Ti) Elemental titanium and titanium dioxide is of a low order of toxicity. Excessive exposure in humans may result in slight changes in the lungs. Tungsten (W) Tungsten has been shown to act by antagonizing the action of the essential trace element, Molybdenum. Long industrial experience has indicated no pneumoconiosis to develop among workers exposed solely to tungsten or its insoluble compounds. Vanadium (V) Vanadium compounds are poorly absorbed through the gastrointestinal system. Inhalation exposures to vanadium and vanadium compounds result primarily in adverse effects on the respiratory system. Chronic exposure to Vanadium Pentoxide (V205) dust and fumes may cause sever irritation of the eyes, skin, upper respiratory tract, emphysema, tracheitis, pulmonary edema, bronchial pneumonia, and systemic poisoning. Signs and symptoms of overexposure include conjunctivitis, nasopharyngitis, cough, dyspnea, palpitation, lung changes, chronic bronchitis, skin pallor, greenish-black tongue and an allergic skin rash.
