NO open flames. Powder, AFFF, foam, carbon dioxide. EXPLOSION Above 88°C explosive vapour/air mixtures may be formed. Above 88°C use a closed system, ventilation. EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Cough. Sore throat. Ventilation. Fresh air, rest.  •SKIN Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Pain. Face shield. 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. 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. Keep in the dark.

International Chemical Safety Cards NEOPENTYL GLYCOL DIGLYCIDYL ETHER ICSC: 0182 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. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. 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 irritates the eyes and the skin . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Relative density (water = 1): 1.07 Relative vapour density (air = 1): 7.5 Flash point: 88°C o.c. ENVIRONMENTAL DATA N O T E S Explosive limits are unknown in literature. Check for peroxides prior to distillation; eliminate if found. ADDITIONAL INFORMATION ICSC: 0182 NEOPENTYL GLYCOL DIGLYCIDYL ETHER (C) IPCS, CEC, 1994
