In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Laboured breathing. Sore throat. Wheezing. Local exhaust or breathing protection. Avoid inhalation of dust . Fresh air, rest. Refer for medical attention.  •SKIN Redness. Itching. Protective gloves. Protective clothing.  •EYES Redness. Pain. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. (Extra personal protection: P2 filter respirator for harmful particles).

International Chemical Safety Cards CERAMIC FIBRES (ALUMINOSILICATE) ICSC: 0123 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS, FIBROUS SOLID. FORMS CRYSTALLINE MATERIALS ON HEATING OVER 1000°C. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure. This substance is possibly carcinogenic to humans. PHYSICAL PROPERTIES Melting point: 1700-2040°C Density: 2.6-2.7 g/cm3 Solubility in water: none ENVIRONMENTAL DATA N O T E S Crystalline materials produced from ceramic fibres when heated over 1000° C present a possibly increased risk to workers.
