International Chemical Safety Cards TETRAETHYLENEPENTAMINE ICSC: 1718 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO YELLOW HYGROSCOPIC , VISCOUS LIQUID . PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic fumes including ammonia , nitrogen oxides . The substance is a strong base, it reacts violently with acid and is corrosive. Reacts with oxidants and chlorinated hydrocarbons. pH is 11.8 OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: Serious local effects by all routes of exposure. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of mist may cause severe swelling of the throat. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization.
