SECTION 2: Hazards identification

Hazard statements

Gray iron castings in their natural state do not present inhalation, ingestion or contact hazards However, dust or fumes from machining, cutting, grinding, welding, brazing, flame cutting and arc gouging will release contaminants into the air, with inhalation as the primary route of entry. Since the castings are primarily iron, the dust and fume generated from the working of these castings will be primarily iron or iron oxide. Flame cutting, arc gouging or welding on these castings may convert a fraction of the chromium to a water insoluble hexavalent (Carcinogenic) form. However, the chromium content of gray iron castings is very low. EMERGENCY OVERVIEW REPRESENTS HAZARDOUS COMPONENTS THAT CAN BE RELEASED DURING PROCESSING.

Potential health effects

Acute Exposure Inhalation Inhalation of high concentrations of metal dust or fume for short periods of time can cause irritation to the eyes, nose and throat. Metal fume fever can also occur, with symptoms of metallic taste, dryness of the mouth, throat irritation and chills and fever, which usually lasts for 12 to 48 hours. Chronic Exposure by Principle Elements Carbon: Prolonged and repeated over-exposure (Inhalation) may lead to benign pneumoconiosis. Chromium: In some workers, chromium compounds act as allergens and my cause dermatitis and may also produce pulmonary sensitization. Chromium and chromium compounds have been identified as carcinogenic substances. Copper: Fumes may cause metal fume fever, with flu-like symptoms and hair and skin discoloration. Keratinization of the hands and feet has been reported. Systemically, dust and fume cause irritation of the upper respiratory tract, metallic taste and nausea. Iron: Iron oxide dust or fumes may cause benign pneumoconiosis (siderosis). This disease may make x-ray diagnosis of other lung conditions difficult or impossible, but causes little or no disability. Manganese: Chronic manganese poisoning may result from inhalation of dust and fume. The central nervous system is the chief site of injury. This is not a fatal disease, although it is extremely disabling. Some persons may be hypersusceptable to manganese. Freshly formed manganese fume has caused fever and chills, similar to metal fume fever. Nickel: The most common ailment arising from contact with nickel or its compounds is an allergenic dermatitis known as “nickel itch”, which occurs usually when the skin is moist. Generally, nickel and most salts of nickel do not cause systemic poisoning, but nickel and some nickel compounds have been identified as suspected carcinogens. Silicon: Accumulation in lungs can cause benign pneumoconiosis, but is not considered to be responsible for pulmonary functional impairment or respiratory symptoms.
