Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION Risk of fire and explosion as a result of decomposition when heated. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE. AVOID ALL CONTACT!  •INHALATION Sore throat. Cough. Closed system and ventilation. Fresh air, rest.  •SKIN Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Burns Safety goggles or face shield . First rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.  •INGESTION Sore throat. Abdominal pain. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Cool. Store in an area without drain or sewer access. Signal: Danger Excl mark-Corr-Health haz Harmful if swallowed Harmful in contact with skin Causes serious eye damage May cause allergic skin reaction Suspected of causing genetic defects May cause cancer Suspected of damaging fertility or the unborn child May cause damage to kidneys through prolonged or repeated exposure if swallowed Harmful to aquatic life with long lasting effects SEE IMPORTANT INFORMATION ON BACK ICSC: 1668 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards EPTAC (70-75 % aqueous solution) ICSC: 1668 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLORLESS TO LIGHT YELLOW, CLEAR, ODORLESS LIQUID PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes under the influence of OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen category: 2 (DFG 2008). ROUTES OF EXPOSURE: The substance can be absorbed into the body in hazardous amounts through the skin, by inhalation of its aerosol, INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys. This substance is probably carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development. PHYSICAL PROPERTIES Density: 1.1 g/cm³ Solubility in water: miscible Octanol/water partition coefficient as log Pow: < -1.3 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised that this substance does not enter the environment. N O T E S Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home.
