International Chemical Safety Cards 3-METHOXYBUTANOL ICSC: 0605 3-METHOXYBUTANOL Methoxy butanol C5H12O2/CH3CH(OCH3)CH2CH2OH Molecular mass: 104.2 CAS # 2517-43-3 RTECS # NONE ICSC # 0605 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 74°C explosive vapour/air mixtures may be formed. Above 74°C use a closed system, ventilation. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE STRICT HYGIENE! INHALATION Cough. Headache. Symptoms may be delayed (see Notes). Ventilation. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. SKIN Dry skin. Burning sensation. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower. Wear protective gloves when administering first aid. 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 Abdominal pain. Dullness. Nausea. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Rest. 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. Cool. Dry. Keep in a well-ventilated room.

International Chemical Safety Cards 3-METHOXYBUTANOL ICSC: 0605 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts with oxidants. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV 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 substance irritates the eyes, the skin and the respiratory tract. Inhalation of (warm) vapour may cause lung oedema (see Notes). Exposure could cause lowering of consciousness. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 160°C Melting point: -85°C Relative density (water = 1): 0.92 Solubility in water: miscible Vapour pressure, Pa at 20°C: 120 Relative vapour density (air = 1): 3.59 Flash point: 74°C Auto-ignition temperature: 335°C Explosive limits, vol% in air: 1.9-?

ENVIRONMENTAL DATA
NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. NFPA Code: H 1; F 1; R 0;
