International Chemical Safety Cards p-CHLORO-o-CRESOL ICSC: 1476 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive fumes . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. 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). Corrosive on ingestion. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 231°C Melting point: 46-50°C Density: 0.48 g/cm3 Solubility in water, g/100 ml at 20°C: 0.23 Vapour pressure, Pa at 20°C: 27 Octanol/water partition coefficient as log Pow: 3.09 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. N O T E S 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. Substance may be transported in a molten form. Transport Emergency Card: TEC (R)-61GT2-II ADDITIONAL INFORMATION ICSC: 1476 p-CHLORO-o-CRESOL (C) IPCS, CEC, 1994
