NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles). Do NOT let this chemical enter the environment.

International Chemical Safety Cards TRIPHENYL PHOSPHATE ICSC: 1062 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALLINE POWDER , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: On heating, toxic fumes are formed. OCCUPATIONAL EXPOSURE LIMITS: TLV: 3 mg/m3 (as TWA) (ACGIH 2000) OSHA PEL: TWA 3 mg/m3 NIOSH REL: TWA 3 mg/m3 NIOSH IDLH: 1000 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 on spraying or when dispersed, especially if powdered . EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the peripheral nervous system , resulting in impaired functions . PHYSICAL PROPERTIES Boiling point: 370°C Melting point: 49-50°C Relative density (water = 1): 1.27 Solubility in water, g/100 ml at 20°C: 0.001 Vapour pressure, Pa at 20°C: 1 Flash point: 220°C c.c. Octanol/water partition coefficient as log Pow: 4.59 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use. N O T E S NFPA Code: H2; F1; R0 ADDITIONAL INFORMATION ICSC: 1062 TRIPHENYL PHOSPHATE (C) IPCS, CEC, 1994
