AL-90, Alumina Brick

SECTION 2: Hazards identification

EMERGENCY OVERVIEW : Solid brick or other form, practically odorless. As-manufactured product does not pose significant fire or health hazards. Refractory particulates formed during processing, installation, maintenance procedures and/or tear-out may be irritating to the skin, eyes and respiratory tract, and may cause pulmonary system effects. Potential for cancer and silicosis exists for long-term exposures to product particulates. Product is noncombustible and stable.

Principle Routes of Exposure

Inhalation: Yes. Skin: No. Ingestion: No. Other: No. EYE CONTACT : Particulates may cause slight to moderate irritation. Abrasive action of dust can damage eyes. SKIN CONTACT : Particulates may cause slight irritation. INHALATION : Inhalation of airborne particulates may cause slight to moderate irritation of mucous membranes. Page 1 of 6 INGESTION : Ingestion is unlikely. If ingested in sufficient quantities, may cause gastrointestinal disturbances. Symptoms may include irritation, nausea, vomiting, abdominal pain and diarrhea. CHRONIC : The prolonged inhalation of dusts containing crystalline silica may result in the development of disabling pulmonary fibrosis known as silicosis. Silicosis is a chronic disease characterized by generalized fibrotic changes and the development of nodules in both lungs, and clinically by shortness of breath, decreased chest expansion, lessened capacity for work, absence of fever, increased susceptibility to tuberculosis, and characteristic x-ray findings. CARCINOGENICITY : IARC has listed crystalline silica from occupational sources as a Group 1 carcinogen. A Group 1 carcinogen is one in which there is sufficient evidence for carcinogenicity in humans. NTP has listed crystalline silica as reasonably anticipated to be a carcinogen. SIGNS AND SYMPTOMS OF OVEREXPOSURE: Irritation, shortness of breath, decreased chest expansion, dry cough, fatigue, dyspnea, cyanosis, loss of appetite, chest pain, total incapacity to work.

Medical Conditions Generally Aggravated by Exposure

particulates) Preexisting diseases or other conditions of the lungs, skin, eyes, and other mucous membranes. Exposure to product dust in conjunction with exposure to other potential carcinogens (such as cigarette smoking) may have a synergistic effect.
