NO open flames. Powder, AFFF, foam, carbon dioxide. EXPLOSION EXPOSURE AVOID ALL CONTACT!  •INHALATION Cough. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Pain. Safety goggles, or eye protection in combination with breathing protection. 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. Rinse mouth. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water. Separated from strong oxidants, strong bases, strong acids. Cool. Keep in the dark.

International Chemical Safety Cards 1,4-BUTANEDIOL DIGLYCIDYL ETHER ICSC: 0110 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance can presumably form explosive peroxides. Reacts with strong oxidants, acids, and bases. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol. 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 irritating to the eyes , the skin and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Boiling point: 155-160°C Relative density (water = 1): 1.1 Vapour pressure, kPa at 20°C: 1.333 Relative vapour density (air = 1): 7.0 ENVIRONMENTAL DATA N O T E S Check for peroxides prior to distillation; eliminate if found. Araldit D4026 is a trade name. ADDITIONAL INFORMATION ICSC: 0110 1,4-BUTANEDIOL DIGLYCIDYL ETHER (C) IPCS, CEC, 1994
