International Chemical Safety Cards TRI-o-CRESYL PHOSPHATE ICSC: 0961 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS OR PALE YELLOW LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating and on burning producing toxic fumes including phosphorous oxides. Reacts with oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 mg/m3 (skin) (ACGIH 1992-1993). OSHA PEL: TWA 0.1 mg/m3 NIOSH REL: TWA 0.1 mg/m3 skin NIOSH IDLH: 40 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin, 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 may cause effects on the central nervous system and peripheral nervous system , resulting in impaired functions (paralysis). Exposure above OEL may result in permanent paralysis. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the nervous system , resulting in impaired functions and muscular paralysis.
