SECTION 2: Hazards identification

29 CFR 1910.1200) Titanium Products as sold by Webco are not hazardous per OSHA GHS 29 CFR 1910.1200. However, individual customer processes, (such as welding, sawing, brazing, grinding, abrasive blasting, and machining) may result in the formation of fumes, dust (combustible or otherwise), and/or particulate that may present the following hazards

Potential health effects

Titanium 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. 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 titanium alloy products may generate airborne concentrations of hexavalent chromium, Titanium Alloy Tubing -SDS | 2 (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. 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) This is considered to be nuisance particulate by the American Conference of Governmental Industrial Hygienists (ACGIH) 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. 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. Titanium Alloy Tubing -SDS | 3 Zirconium (Zr) Zirconium compounds can affect the body if they are inhaled or if they come in contact with the eyes or skin. Skin rash has been reported from exposure to zirconium-containing deodorants. Zirconium compounds have been reported to cause radiographic changes in animals due to pulmonary retention. Zirconium hexachloride may be irritating to the mucous membranes of the respiratory tract. Zirconium may cause granulomas of the skin.
