In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE SEE EFFECTS OF LONG -TERM OR REPEATED EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Sore throat. Laboured breathing. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Itching. Protective gloves. Protective clothing.  •EYES Redness. Pain. Itching. 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 containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles).

International Chemical Safety Cards ROCK WOOL ICSC: 0194 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: FIBROUS SOLID. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV: (as TWA) 1 f/cc A3 (ACGIH 1999). 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. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is possibly carcinogenic to humans. The carcinogenic potential depends on the length, diameter, chemical composition and biological persistence of the fibre. Expert advice should be sought when working with this material. PHYSICAL PROPERTIES Solubility in water: none ENVIRONMENTAL DATA N O T E S Rock wool is an amorphous silicate manufactured from rock. May contain a binder and an oil for dust suppression.
