NO open flames, NO sparks, and NO smoking. Foam, dry powder, carbon dioxide. NO water. EXPLOSION Above 21°C explosive vapour/air mixtures may be formed. Above 21°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Cough. Sore throat. Dizziness. Headache. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Pain. Dry skin. Protective clothing. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles, or 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. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Cover the spilled material with dry earth, sand or other non-combustible material. Collect leaking liquid in sealable containers. Remove all ignition sources. Ventilation. Do NOT wash away into sewer. (Extra personal protection: filter respirator for organic gases and vapours.) Fireproof. Cool. Keep in the dark.

No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards DIPROPYL ETHER ICSC: 0468 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance can presumably form explosive peroxides. The substance decomposes on burning producing toxic gases and irritating fumes . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: A harmful contamination of the air will be reached rather slowly 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 . Exposure at high levels could cause lowering of consciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 88-90°C Melting point: -122°C Relative density (water = 1): 0.7 Solubility in water: 0.25 g/100 ml at 25 °C Vapour pressure, kPa at 25°C: 8.33 Relative vapour density (air = 1): 3.53 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2 Flash point: 21°C c.c. Auto-ignition temperature: 188°C Explosive limits, vol% in air: 1.3-7 Octanol/water partition coefficient as log Pow: 2.03 ENVIRONMENTAL DATA N O T E S Check for peroxides prior to distillation; eliminate if found.
