International Chemical Safety Cards ZINC CHLORIDE FUME ICSC: 1064 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE, HYGROSCOPIC FUME , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: Corrosive to metals. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: 1 mg/m3 (as TWA); 2 mg/m3 (as STEL) (ACGIH 1992-1993) OSHA PEL: TWA 1 mg/m3 NIOSH REL: TWA 1 mg/m3 ST 2 mg/m3 NIOSH IDLH: 50 mg/m3 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 is corrosive to the eyes, the skin, and the respiratory tract. Inhalation of the substance may cause lung oedema (see Notes). Exposure to high concentrations may result in death. The effects may be delayed. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Boiling point: 732°C Melting point: 283-290°C Relative density (water = 1): 2.9 Solubility in water, g/100 ml: 432 Vapour pressure, kPa at 428°C: 0.13 ENVIRONMENTAL DATA NOTES The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
