Effects of over exposure
•
Eye: Avoid contact with eyes. Slightly to moderately irritating. Abrasive action
may cause damage to outer surface of eye.
•
Inhalation: May cause respiratory tract irritation. Repeated or prolonged
breathing of particles of respirable size may cause inflammation of the lung
leading to chest pain, difficulty breathing, coughing, and possible fibrotic
change in the lung (pneumoconiosis). Pre-existing medical conditions may be
aggravated by exposure: specifically, bronchial hyper-reactivity and chronic
bronchial or lung disease.
•
Ingestion: May cause gastrointestinal disturbances. Symptoms may include
irritation and nausea, vomiting, and diarrhea.
•
Skin: Slightly to moderately irritating. May cause irritation and inflammation
due to mechanical reaction to sharp, broken ends of fibers.
Exposure to used ceramic fiber product
Product which has been at service in elevated temperatures (greater than 1800
°F/982 °C) may undergo partial conversion to cristobalite, a form of crystalline
silica which can cause severe respiratory disease (pneumoconiosis). The amount
