International Chemical Safety Cards NAPHTHA (PETROLEUM), HYDROTREATED HEAVY ICSC: 1380 Low boiling point hydrogen treated naphtha Catalytic Reformer Feed ICSC #    1380 CAS #     64742-48-9 RTECS # UN #        3295 EC #         649-327-00-6 March 15, 2001 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. NO open flames, NO sparks, and NO smoking. Water spray, alcohol-resistant foam, powder, carbon dioxide. EXPLOSION Above 40°C explosive vapour/air mixtures may be formed. Above 40°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Dizziness. Headache. Drowsiness. Nausea. Unconsciousness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Dry skin. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Cough. Diarrhoea. Sore throat. Vomiting. (Further see Inhalation). Do not eat, drink, or smoke during work. Do NOT induce vomiting. Refer for medical attention. See Notes. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. (Extra personal protection: filter respirator for organic vapours of low boiling compounds.) Fireproof. Separated from strong oxidants. Well closed.

International Chemical Safety Cards NAPHTHA (PETROLEUM), HYDROTREATED HEAVY ICSC: 1380 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts with strong oxidants, causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour and by ingestion. 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 vapour is slightly irritating to the eyes . The substance may cause effects on the central nervous system . Exposure to high concentration of vapours may result in unconsciousness. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. See Notes. PHYSICAL PROPERTIES Boiling point: 155-217°C Melting point: < 0°C Density: 0.76-0.79 g/cm3 Solubility in water: none Vapour pressure, kPa at 20°C: 0.1-0.3 Flash point: 40-62 °C c.c. Auto-ignition temperature: 255-270 °C Explosive limits, vol% in air: 0.7-6.0 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. N O T E S This is a mixture of C9-C13 naphthenes, iso- and n-paraffins. Neither the concentration of aromatics nor of hexane is greater than 0.1% by volume.Note P: the EU classification as carcinogen (R45) does not apply if it can be shown that the benzene content is below 0.1% by volume. Depending on the raw material and the production processes, the composition and physical properties of this solvent can vary considerably. The symptoms of chemical pneumonitis do not become manifest until a few hours or even a few days have passed. Exxsol D40 / D60, Shellsol D40 / D60, Hydrosol P 150 / 180, among others, are trade names.
