International Chemical Safety Cards GLASS WOOL ICSC: 0157 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS , FIBROUS SOLID. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV: 1 f/cc A3 (as TWA) (ACGIH 1997). 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: Repeated or prolonged contact with skin may cause dermatitis. Tumours have been detected in experimental animals but may not be relevant to humans (see Notes). PHYSICAL PROPERTIES Relative density (water = 1): 2.5-2.6 Solubility in water: none ENVIRONMENTAL DATA N O T E S Glass wool is an amorphous silicate manufactured from glass. May contain a binder and an oil for dust suppression. Do NOT take working clothes home. JM (John Manville) 100, JM102, JM104, and JM110 are trade names.
