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. Mineral Oils are suspect carcinoma of the skin, scrotum, larynx, lung and alimentary-tracts.

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. Antimony (Sb) Very hazardous in case of ingestion. Causes damage to the following organs: blood, kidneys, lungs, the nervous system, liver, mucous membranes. Arsenic (As) Very hazardous in case of ingestion, of inhalation. Slightly hazardous in case of skin contact (irritant), of eye contact (irritant). Causes damage to the following organs: kidneys, lungs, the nervous system, mucous membranes. Beryllium (Be) Overexposure to airborne beryllium particulate may cause a serious lung disease, in certain sensitive individuals, called chronic beryllium disease (chronic berylliosis). Chronic beryllium disease is a condition in which the tissues of the lungs become inflamed, restricting the exchange of oxygen between the lungs and the bloodstream. Symptoms may include cough, chest pain, shortness of breath, weight loss, weakness, and fatigue. Long term effects may include loss of lung function, fibrosis, or subsequent secondary effects on the heart with eventual permanent impairment Carbon (C) Considered to be a nuisance dust. Excessive dust exposure may irritate the eyes and respiratory tract. 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 ferr0chromium alloys may cause lung changes in workers exposed to these alloys. Exposure to Chromium metal does not give rise to pulmonary fibrosis or pneumoconiosis. 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. Lead (Pb) Acute of long-term excessive inhalation exposures to the fumes or dusts of inorganic lead compounds (such as lead oxide) can adversely affect several organ systems including the nervous system, the digestive system, the blood and blood-forming system and the renal system. Early effects are characterized by fatigue, constipation, muscle aches, abdominal pains, and decreased appetite. Later signs and symptoms can include anemia, pallor, a “lead line” on the gums, and reduce-grip. Severe central nervous system and symptoms effects (referred to as lead encephalopathy) usually only occur after heavy and rapid lead exposures. Signs and symptoms may include headache, dizziness, convulsions, delirium, coma and possibly death. Long-term exposures can also produce kidney damage. 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. 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. Phosphorus (P) The dusts and fumes can act as minor irritants to the eyes, throat, and respiratory tract. Long-term excessive inhalation of phosphorus compounds may lead to cough, bronchitis and pneumonia. Selenium (Se) Hazardous in case of eye contact (irritant), of ingestion, of inhalation. Slightly hazardous in case of skin contact (irritant). Silicon (Si) This is considered to be nuisance particulate by the American Conference of Governmental Industrial Hygienists (ACGIH) Zinc (Zn) The inhalation of zinc oxide fumes has been shown to result in a condition known as metal fume fever. The symptoms include fever, chills, muscular pain, nausea and vomiting, but complete recovery occurs in 24 to 48 hours. The same effects are produced by the fumes of some other metals and can also result from breathing finely divided zinc oxide dust. It is generally agreed that metal fume fever is a temporary condition of brief duration and without after effects and without medical evidence of chronic effects. A limit of 5 mg/m3 is recommended for zinc oxide fumes. It is believed that if concentrations are kept below this level, the incidence of metal fume fever will be low and any attacks which do occur will be mild. Non-Metallic Coatings: Prolonged and/or repeated skin contact with lubricants and rust inhibitors may cause dermatitis. In addition, inhalation of excessive concentrations of vapors or gases, e.g. carbon monoxide (from welding, burning, etc.) may result in dizziness, nausea, headaches, and respiratory tract irritation. Mineral Oil- a laxative, inhalation of vapor or particulates can cause aspiration pneumonia.
